    Super-capacitor will be a good lithium-ion battery of additional equipment








    So far, the industry agreed that the lithium-ion batteries for electric cars is still the main way of energy reserves, but now have several companies began to consider using a super capacitor (ultracapacitor) lithium-ion battery products as a good additional equipment.



    South Korea will be an electronics company Neescap Tuesday claimed that 9 million U.S. dollars will be invested to expand its transportation, electric power systems and consumer electronics products with super capacitor (ultracapacitor) the product capacity. In the United States and ability to design and manufacture of super-capacitor products and electrolyte materials needed for the company There GrapheneEnergy, EnerG2 and Ioxus 3. Another one EEStor companies by VCs KleinerPerkinsCaufield & Byers as the background, now the company has signed an electric car company Zenn super-capacitor supply agreement.



    The more traditional batteries, super capacitors can store the electricity are not many. So at home Rechargeable (Plug-in) electric vehicles, such a capacitor can not serve as power supply equipment alone, but need to tie in with the fuel cell use. On the other hand, the super capacitor is also equipped with fast-diarrhea release energy stored in the ability. In addition, the capacitor charging time is very short, only takes a few seconds or minutes of time will be able to complete the charge, but charge several times the performance of there will not be reduced.



    Capacitor current consumer electronics products have been used in digital cameras and other occasions, in order to flash this need momentary high-energy input of the device provides energy supply. According to experts, super capacitor the key issues facing the future is how to increase the kinds of capacitor voltage so that it can in the high-voltage environment.



    According to Ioxus engineers said, the super capacitor is environmentally friendly energy, a good supplement can make batteries, fuel cells, solar or wind power generation, power supply would be more perfect. At the same time capacitor used in the production of such materials are also very environmentally friendly, the price Some are more readily accepted.



    Super capacitor technology, the future development direction:



    Massachusetts Institute of Technology computer electronic engineers JoelSchindall said that in the next few years, the super capacitor energy storage capacity will be a qualitative leap forward. The current super capacitor product discharge rate is 10 times that of traditional batteries, while the energy storage capacity in the volume of the same only the latter under the condition of 5%.



    He said: "super-capacitor charge and discharge operations of certain frequent use of a great occasion, such as Brake Energy Recovery-type brake system (that is, five sets of F1 shows on CCAV all day nagging what Coles host system), This capacitance is very easy to use. Of course, this product is currently not yet a large scale to replace the batteries. "



    Over the past five years, Schindall led research team has been studying the super capacitor in the energy storage component - porous carbon material, replaced with another carbon nanotube conductive matrix material + energy storage components. Earlier this year they have been established to the FastCap companies, in order to the commercialization of research results.



    Schindall said the super capacitor energy storage capacity of the product will eventually reach about 25% of the SONY VGP-BPS2 Battery. Massachusetts Institute of Technology developed at present out of nano-materials, energy storage capacity has reached twice the level of carbon materials. But the next few months, he led research team will be showing the kind of energy storage capacity is five times more activated carbon products.

    Why lithium batteries into a "time bomb"








    Planting the seeds of electrolyte "missile"



    According to the U.S. well-known science writer series of articles in the lithium batteries in the introduction, the vast majority of lithium battery explosion caused by a short circuit, and the specific reasons, including charging overvoltage / over-current use of aging.



    Lithium battery manufacturing process, because the manufacturing process itself flawed, it is easy to be insulated in this between the two poles, leaving metal dust, copper foil, aluminum foil pieces. The angle is expected in the battery than the fever (more common in long-term use or charging), the like boiling water in a grain of rice, as in the electrolyte to make random thermal motion. If you happen to have the APPLE 15-INCH ALUMINUM POWERBOOK G4 SERIES Battery positive and negative particles or debris near the middle of the diaphragm level, it could create a divide perforation, triggering micro-short circuit. As the batteries are flammable organic electrolytes, micro-short-circuit may cause an explosion, burning and other accidents, generally have the following three cases:



    1. Sparks ignited the electrolyte, and thus bring disaster to come into contact with plastic body and flammable, resulting in fire;



    2. Was experiencing an increase of temperature caused by the battery, the battery inside the space is small, perhaps because of increased pressure to explode;



    3. Batteries slower rise in temperature, the battery case to melt gradually, so that corrosive electrolyte leakage.



    Lithium battery safety problems can not stop now, because then the advanced manufacturing technology, will inevitably lead to planting the seeds in the electrolyte "missile." Should be noted that the formal sector of lithium battery production and sales have strict norms of acceptable quality lithium batteries, the number and size of debris have been controlled within a very small, very low risk of perforation of diaphragm; Battery Case also used flame-retardant material, is not prone to fire.



    The explosion-proof lithium battery of measures



    Lithium battery safety problems, the battery manufacturer, of course well aware, then what they used explosion-proof measures? Li-ion batteries for notebook computers, for example, its working principle is: Lithium batteries near full charge and discharge almost drained when the voltage drop, the control circuit detects this situation, notify the protection circuit cut off power supply to prevent overcharge or excessive discharge, so as not to shorten battery life.



    The current notebook lithium batteries possess a more complete multi-level protection mechanism, even in the power charger, notebook computers unusual circumstances, the laptop battery can also be converted to automatic protection status, is generally not an explosion. But once the control circuit and protection circuit of the ability to work reduced hours, the battery on the verge of "dangerous" the. Mobile phones and other electronic products, lithium battery charge and discharge protection mechanisms, similar to this.



    Do not need it "at arm's length"



    In recent years, lithium-ion electronic products explosions often found newspapers, aroused a lot of consumer panic, some people for their own mobile phones, MP3 charging often "at arm's length"; also because of fear, simply a long-term will be cast aside laptop battery, cause scrap. However, survey results, the majority of lithium battery explosions are the result of the user pay attention to safety tips, such as unauthorized modification, use of non-matching charger, the battery placed in extreme environments such as making.



    Should be pointed out that the lithium battery technology as a kind of after 30 years of study, has successfully commercialized the mature technology, its safety is guaranteed. Regular brands of lithium batteries at the factory will have been numerous Road test procedure after they are sold as well as information feedback mechanism in order to recall the product in question in time.



    United States Transportation Security Administration (TSA) is given following the recommendations of the safe use of lithium batteries:



    1. Using the original charger: Li-ion battery charging time is the high period of bombing. Than the original battery charger is compatible with the battery charger to ensure better security.



    2. Use of a reliable battery: try to buy original batteries, not to save money to buy "second-hand goods", such batteries may be through maintenance, and reliable than original batteries.



    3. Do not place the TOSHIBA SATELLITE A105 SERIES Battery extreme environments: high temperature, collisions, etc. are all important causes of battery explosion, as far as possible so that the battery is in a stable environment, away from the high-temperature areas.



    4. Do not try to modification: Many young people like their phones to "cosmetic", but it was "bold but cautious" manner to transform mobile phone on their own. However, it can easily lead to improper modification accident. Mobile phone is a sophisticated communications equipment, in the design, manufacturers will have on its security, strictly textual research. After modification, the battery may be at not taking into account the environment before, an increase of security risks.

    Applied Technology clever use of laptop battery








    Use rechargeable batteries



    Use rechargeable batteries for notebook computers, one of the relative advantages of the desktop, it can greatly facilitate a variety of environments the use of notebook computers. Introduced the first battery is nickel-cadmium batteries (NiCd), but this HP F4098A Battery has a "memory effect", each charge shall be required before discharge, very easy to use, and soon was nickel-metal hydride battery (NiMH) replaced, NiMH not only failed to "memory effect", but can make more per unit weight of 10% of the electricity. The most commonly used battery is lithium-ion battery (Li-Ion), it is also no "memory effect", as compared with the NiMH per unit weight gain more power, the price twice as high than the NiMH. In the same weight, this three kinds battery is 1:1.2:1.9 ratio.



    Notebook computer batteries currently used in three kinds of main categories: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Ni-Cd NI-CD, Ni-MH NI-MH, Lithium-Ion battery LI.



    The purchase or replace the battery when the laptop for many users, the "batteries" may be unfamiliar. The outset, batteries and battery are two concepts. A battery is composed of several slightly larger than the thumb, cylindrical, height of about 7,8 cm, voltage is 3.6v of small units. They are the batteries, just like a small battery, through the series combination, that is, we see the battery has. Then talk about how to determine if the battery is several cores:



    One way: Disconnect the battery to the number of contacts to see him, there are a few of the tens of cores. But this is a "minister" approach. Let's take a look at "Cao Chong" is how, "said the elephant": the look of your battery nominal number of v, such as 14.4v, and then divided by 3.6 to be 4, then proved to be four batteries together in series. And then take a look at the capacity of the battery block, for example 3800mAh, then prove that the above mentioned two sets of batteries in series, because the small battery capacity is 1500-2000mAh, even more, to be two to reach 3800mAh. According to these two judgments, then the battery is 4 × 2 = 8 cores.



    The composition of laptop battery



    Laptop battery from shell, circuit boards and batteries, belonging to lithium-ion battery. People are talking about batteries in general refers to the number of batteries within the battery, mAh refers to the laptop battery capacity.



    Mainly by the protection circuit board (or the secondary protection circuit), and the capacity of directed circuits of two parts, notebook battery charge and discharge and safety management.



    Laptop battery standby time mainly by the mAh value to decide. Under normal circumstances, a few more batteries, mAh value is greater the longer standby time. Laptop battery life mainly by the charge and discharge times to measure the quality of the products are generally eligible for 500-600 times. Therefore, the effective use of laptop batteries within a period of two years, expired the battery will be aging, standby time affect the sharp decline in the mobility of notebook computers.



    Laptop battery tips



    In fact, how to make good use of laptop batteries battery, how to extend their use of time and the use of life and so on, is undoubtedly the troubled minds of the majority of notebook users, a problem, the use of laptop batteries There are many methods and techniques, which requires us to usually use more learning and application.



    (A) rapid access to hibernation



    Temporary non-use of laptop computers, in order to conserve battery power, we can set the power management program, allowing the system to enter sleep mode after a period of time, but this is a shorter or longer will have to wait a few minutes, there is no way to make laptop computer system immediately enter the sleep state?



    Notebook computer system to enable quick access to dormant state of a simple method is to directly close the display. Press the display would require little effort, you can make notebook computers into sleep mode immediately and effectively conserve battery power. When you need to re-used time, as long as the opening screen, the system will automatically return to pre-operational state.



    (B) the screen-saving mode



    TFT screen is the largest notebook computer power components, in order to reduce its use of the battery when the power consumption, notebook manufacturers have devised ingenious schemes, but in general are based on the lower screen brightness, and even turn off the IBM THINKPAD T42 SERIES Battery.



    In some notebook computer's power management settings you can customize the brightness of the screen, most of notebook computers by a specific shortcut keys adjust screen brightness, generally 6 to 8-level brightness adjustment.



    (C) energy-saving settings



    Desktop machines using alternating current, most people may not be the computer attached great importance to energy-saving features, but need to use battery-powered notebook computers, the use of energy-saving features should be taken seriously. How to design computer hardware more energy-efficient, this is not a user problem to be solved. The user can do is set up on the computer the effective use of energy-saving option.



    Energy-saving settings require the user to adjust two: First, the computer's BIOS setup program on the energy-saving mode in the settings; most important thing is there are many energy-saving in the operating system settings and operations. In the practical implementation of computer systems, Windows systems should take precedence over energy-saving settings in the CMOS settings.



    1. BIOS in the energy-saving settings



    In the CMOS settings, most had a "Power Savings", which can choose to "Maximum Battery Life" and "Maximum Performance" and other options. "Maximum Battery Life" is the default power saving mode setting. Notebook computer power saving mode in several states, such as the Idle Mode Idle Mode, Standby Mode standby (wait) mode, Suspend Mode suspension (sleep) mode. Notebook computers, these settings have been able to regulate power consumption, mainly in the computer into energy-saving state, the timely closure of some without the use of the system equipment. If the wait state, turn off the screen and hard drive; into hibernation, apart from a close monitor and hard drive, but also the contents of memory can be saved to the hard disk, the basic maintenance of the entire computer system shut down, once activated, or restart the computer, desktop will be accurately restored to pre-hibernation state. The energy-saving settings in the CMOS, mainly set by the Idle Mode to enter Standby Mode to Standby Timeout time, set to enter Suspend Mode from Standby Mode to Suspend Timeout time. Phoenix BIOS notebooks are most common. Different energy-saving BIOS settings may be somewhat different, it should carefully read the screen prompts.



    2. Windows in the energy-saving settings



    For the average user, in the Windows system to operate a better understanding of energy management can be simpler. Windows Help file, in the "management of hardware and software" entries, there are two notebook computers with energy-saving elements relating to: "Managing energy consumption" and "use of portable machine" in the "management laptop on the power." Energy-saving settings during Windows, should read the contents.



    In the Windows "Control Panel", click "power management", you can open the "Power Management Properties" dialog box. In the "Power Management Properties" dialog box, should be "power scheme" is set to "Portable / Laptop" and reasonable arrangement "system waiting for", "close the Monitors", "Turn off hard disks" and other options for . Different computer can control the option to have some differences, the new factory and the latest computer software will be more workable options, detailed settings should be based on the computer's own features and Windows Help files to carry out.



    In addition, if your laptop built-in infrared port, not the time to ban it, it can be extended laptop battery life.



    (D) alarm settings



    Set battery alarm in time to give prompt the user to save the information. Way is to click on Open "Control Panel", double-click "Power" option, point "alarm" menu bar, "low-battery alarm" column, Windows 98 default is 10%, "a serious shortage of the battery alarm" column, Windows 98 default is 3% can make the appropriate modifications as needed. Click both the [alarm response] button, the "voice alert" and "displays the message" are selected, "the power level" may from time to select. Alarm limits so that when the battery is used, it will pop up a warning window, and the alarm buzzer sounds to alert the user to save information on a timely manner. Finally click [OK] button to exit the power management settings.



    (E) open the energy-saving function



    In the "extended laptop battery life technology" section, we have introduced energy-saving feature is the use of a CPU technology, which allows the performance make notebook PCs to play with their ASUS EEE PC Battery life between the time to achieve the best balance.



    Most new models of notebook computers both in the BIOS of the CPU energy-saving technology have given the support, by default is turned on, if not open as long as the enter the BIOS will support the option to open it OK.



    (Vi) The use of third-party software to monitor battery status



    In addition to Windows built-in power management features, there are many utilities available to monitor the battery condition. For example, PowerCenter is a power monitoring tool available for free download (http://me MBers.xoom.com / TimothyBug / powercenter / index.htm). Only 800KB, is designed for notebook computer services software. In addition to the amount of PowerCenter shows the percentage of battery, but also to show the actual time and hours of time can be used.



    PowerCenter total of three kinds of display.



    (1) FullDisplay: In the open window displays detailed information, including the use of battery or AC power, the battery percentage and the remaining time available.



    (2) CompactDisplay: in use is always at the top of the window display.



    (3) MinimizeDisplay: make PowerCenter reduced to the Windows task bar, display the information is relatively simple.



    PowerCenter is also attached to a control center, can be made up to six kinds of warning. When the battery - down to a certain level, a timely warning to the user, save the file being processed. In order not to waste electricity and CPU resources, PowerCenter automatically detect the battery status changes.



    (G) intentionally run out of battery



    Run out of Dell INSPIRON 6000 Battery on a regular basis in order to ensure a full charge. If you need to completely run out of battery power in the specific practice is: In the Power Management dialog box, select Battery Drain this particular power mode, all of its 3 Running on Batteries options are set to Never, this notebook computer on the will continue to run. Select the mode, and then enter the Alarms tab to lift the Low Battery and Critical Battery Warning check box is a check mark (so, when the battery power is low, the machine will not enter the suspended state). Next, let the computer run the CPU-time tasks, such as the computer automatically run a number of computational complexity of the 3D demo program, so soon run out of battery power remaining, of course, these disposal not forget to unplug the AC plug.

    Hewlett-Packard: quick profit, or will lose their competitive advantage in the Chinese market








    A few months ago, Hewlett-Packard's third-quarter results, HP Personal Systems Group third-quarter revenue of 8.4 billion U.S. dollars, down 18% year on year, in which revenue fell 10 percent laptop, desktop revenue fell 26%. Although HP is still occupying the top spot in the global computer industry, location, but the face of the corporate sector adjustment stimulate competition among peers, as well as worldwide, repeatedly broke the product quality problems, particularly China, the quality of the notebook market, frequent problems, Hewlett-Packard to maintain its current position, not always been easy.

     

     



    Global personal computer market's crowded



    With the global economic recovery, the computer market began to pick up. Recently, the market research report published by IDC, global PC shipments top five computer manufacturers, in addition to Dell last quarter, a decline, other four showed a COMPAQ PRESARIO 2100 Battery to increase.



    Last week, Lenovo's new one-quarter earnings freshly baked. Financial report not only shows that Lenovo began to turn around, and the global personal computer shipments increased by 17% year on year, which made Liu was "very satisfied." Lenovo's strong rebound in business, mainly due to China and other emerging markets for the contribution of group sales, particularly in its stronghold of Lenovo's sales in China rose 28 percent, sales increased 9%, with the words Lenovo CEO Yang Yuanqing "China once again played a 'mainstay' role."



    Also last week, some media reported that worldwide PC market share rose to second place just Acer chairman JT Wang said Acer's notebook shipments this year will be more than 30 million, and next year will exceed 4000 10000. This figure, so that Acer is expected to go beyond HP, and become the world's largest notebook maker.



    Hewlett-Packard in this fierce battle, the same active adjustment strategies. Hewlett-Packard Asia Pacific and Japan, regional president, said Xue Jinde, HP will strengthen the Chinese market, sales channels. The end of this year, China's sales network covers cities from the current 700 to 2000.



    Price war ignore the quality of service



    As the market pick up, competition is increasingly fierce, some recent brand computers also frequently be exposed quality issues. October 27 to October 30, Acer, Sony, Asus were submitted to the State General Administration of Quality Supervision, Inspection notebook computers and related equipment on the recall report. Among them, Acer decided to recall the number of Chinese territory involving a total of 12266 units, three kinds of models of notebook computers; Sony decided to replace free of charge in mainland China a total of 1715 units of power adapter; ASUS decided to recall laptop batteries around 3630.



    Some analysts have pointed out that, due to the highly competitive notebook market, manufacturers of products for the price of "dropping lower and lower," product cost compression, causing the security problem is one of the reasons. Some manufacturers have admitted in recent years, the highly competitive notebook market, the profit margins of notebooks have become less dominant in the market in order to not only the product to keep pace, the price should have an advantage, to cheap, the cost have a certain control.



    In fact, HP's product quality issues, has long been China's major media exposure. Started the previous two years, until last year's outbreak of "snow-screen" event, and this year appeared one after another "splash screen" event, HP notebooks have become the main characters, but at the AQSIQ Web site, and did not see the relevant recall information. Can be said that the blind pursuit of product shipments and market share, lower prices, lower costs, ignoring the product quality and after-sales service will only lead to widespread dissatisfaction with Chinese consumers. In the People's Network IT channel related investigations, more than 95% of Internet users expressed the impression that HP was "extremely disappointing", while more than 99% of Internet users expressed a desire for Hewlett-Packard, "the issue in this recall."



    Qiao advantage of this legal gap or infuriating consumers



    In the "AQSIQ Defective Product Management Center" web site, the most recent time in HP's recall of defective products, information is in the last year's June 2. That HP worldwide recall of about 203,000 notebooks buggy batteries, the number involved in China is about 15000. However, this time it is precisely the large-scale outbreak of "snow screen", when, why HP only within the framework of the global recall of laptop batteries, while ignoring the local Chinese region's "snow screen" problem?



    According to "China Quality News" report, HP's recall of batteries is in line with the U.S. Consumer Product Safety Commission's requirements to implement. However, there are still no information on defective electronic product recall laws and regulations. Perhaps, this is giving some companies the opportunity to avoid legal risks, giving the company save a lot of expenses.



    But this clever approach has angered consumers. In the Baidu search engine, enter "HP snow-screen" and "HP splash screen" keyword, the search results more than 40000 and 90000, respectively. Almost all the video sites, can find User upload their own shooting problems on the HP notebook video. Some of the video, HP notebook computers which displayed a variety of unusual phenomena, and still others are angry at the matter and notebooks to consumers shattered. Some TV stations also carried a report on this incident, interviews, many consumers Hewlett-Packard Co. and their agents are very disappointed with the attitude of indifference.



    Quick profit or to lose the Chinese market Hewlett-Packard



    Perhaps the market is eager to compete for the computer maker's mentality. However, the ants of the hole, ACER ASPIRE 3000 Battery bursts thousands of miles. The brands are the sum of all intangible assets holographic concentrated, consumers will buy the brand as the computer, it is because of the brand's trust. But if these brands can not control the quality of the computer business, will ultimately be abandoned by consumers, the brand no longer is the enterprise's cash cow, but simply a sign of just worthless.



    Hewlett-Packard and Lenovo, Acer, the two local computer makers in a competitive Chinese market, which already lacked natural advantages, if the product quality and service attitude ignores consumers, relying on "Little Smart" means to obtain results on the glory, it is Hewlett-Packard is difficult to imagine how the Chinese market, and even a foothold.

    Microbial fuel cell research and application of the latest developments








    Microbial fuel cell (MFC) is a kind of micro-organisms as the anode catalyst, the chemical energy directly into electricity biological device. The use of MFC can not only directly in the water or sludge in the organic matter degradation, but also in microbial metabolism of organic compounds can be generated in the process transformed into an electronic current, to gain power [lj. Since Fes 10-reducing bacteria has been reported that the electrochemical activity, the study found no medium for the microbial fuel cell can be used to operate the bacteria sony pcga-bp2r laptop battery, as a renewable alternative energy sources and new sewage treatment methods, microbial fuel cell has given rise to of particular concern. I will focus on research and microbial fuel cell related internal parameters and to explore better ways of improvement, to improve the performance of microbial fuel cells.

         A microbial fuel cell to obtain the power density

        Due to the presence of a high resistance limits the maximum power density, therefore, from the microbial fuel cell to obtain the upper limit of the power levels still remain unknown. Several groups of studies have shown that microbial flora and fuel with similar microbial fuel cell can produce 10 times the difference between the number of maximum power density. Can be seen that the performance of microbial fuel cells and reactors from the configuration of factors related to the decision, such as the super-potential and resistance. Chemical fuel cells, microbial fuel cells with a higher number of 10 times the power density [lv〕. This is because the micro-device within the various system parameters to increase its resistance, such as water and organic nitrogen demand, anode catalyst and reactor configuration and so on. Therefore, the reactor must be optimized geometry and the electrolyte, thereby reducing the resistance and to the catalytic potential of microorganisms to maximize.

         Two rate-limiting factor in microbial fuel cells

        Like other fuel cells, micro fuel cell performance is by the current, power density and fuel oxidation rate decision. The factors that affect the fuel oxidation rate more, including the catalytic activity of the anode, fuel-proliferation, the spread of electrons and protons, and consumption.

        2.1 The choice of anode catalyst micro-organisms

        From the view of the composition of microbial fuel cell anode can be attached to micro-organisms and transmission of electronic, is to determine the microbial fuel cell produced electricity generation capacity is an important factor, is to study micro-organisms producing electrical and electronic transfer mechanism rationale an important supportive tool, so the microbial fuel cell anode study has very important significance.

        Learned person in microbial fuel cells, activated sludge or anaerobic sludge digestion device, you can generate 0.6V open-circuit potential, closed-circuit when the current can be ignored. To the anode chamber to repeat the supply of fuel, 2 ~ 3 weeks, current can gradually reach a stable value. Analysis of the small ribosomal (165rDNA) showed that bacteria on the anode is different from the use of sludge as inoculum of the bacterial flora Qing〕. Concentrated microbial groups in terms of performance is determined by its dell inspiron 1525 laptop battery, concentrated the most suitable poly-microbial can improve fuel efficiency provided by and used under the given conditions to promote microbial fuel cells run successfully.

          In the enrichment process, using pure culture of the microbial fuel cell electrode surface covered with biofilm. Forming microbial biofilm between cells and electrodes of electronic, you can through insoluble Fe3 10 as the electron acceptor to restore direct contact between the electronic transfer of Qing〕, or to pass through special pili. Some data indicate that some bacteria can produce a natural body of electronic flow, but flow of microbial fuel cell within the e-produce biological importance has attracted suspicion.

         2.2 Proton mass transfer

        Like with the chemical fuel cells, micro fuel cells are also used cation-exchange membrane, in microbial fuel cells proton mass will not be restricted, if the operation in similar conditions, microbial fuel cell anode catalytic activity than the activity of chemical fuel cells low. In general, the chemical fuel cells, microbial fuel cells can produce more than one nursing a height of about a few times the current density. Microbial fuel cell cathode proton consumption rate than the rate of transport through the membrane faster-ching〕, this difference may be caused by microbial fuel cells and fuel cells, the intrinsic chemical differences. Microbial fuel cell using a variety of inorganic compounds, in addition to things, as a fuel for the maintenance of microbial metabolism, while chemical fuel cell is a simple as fuel. Microbial fuel cell used in the chemical substances in the aqueous phase decomposition of cation, the concentration ratio of these cations under neutral pH, the proton concentration was significantly higher than a nursing-fold [2s mouth, they can interfere with transmembrane proton transport. Microbial fuel cells proton mass Another limiting factor is the water quality as the electrolyte solution of choice.

         Rozendal, etc. verify the cathode chamber by a layer of the Nafion 117 membrane transport cation transport effect and the effect of microbial fuel cell performance honk〕. In the two-bedroom with a yin and yang of the microbial fuel cell, transported to the cathode from the anode chamber room to remove the proton (K +, Na +, NH death, Mg, +, Ca "+) cations outside the positive charge carried by the quantity and through Circuit transferred the same number of electrons. Analysis of microbial fuel cell from the film shows, K + and Na + membrane sulfonate residues account for about 74%. cation transport does not depend on the concentration gradient to complete, but an electrodialysis process. In fact, this means that there is no microbial fuel cell proton transport, mainly through the neutral cation transport, rather than proton transport to sustain. This phenomenon raises a range of electrochemical and microbiological the problem, which affected the efficient operation of microbial fuel cells. acidification in the anode chamber of the increase in anode potential while reducing the activity of microbial catalytic anode reaction, while the cathode chamber reduced the anodic potential is alkaline. you can go to film or containing low concentrations of cations with the electrolyte to avoid this cation a priority, rather than proton transfer.

        Usually close-fitting manner microbial fuel cell to avoid the two electrodes short-circuit, this time to film the performance of microbial fuel cell to maximize Tian〕. As the cathode current room will salt or acid solution into the increase. This shows that the proliferation of protons in the aqueous phase is a slow process, with a high salt concentration in the electrolyte to the membrane microbial fuel cell in the proton diffusion rate of speed. As mentioned above, salts inhibit transmembrane proton transport, but the promotion of protons in the aqueous phase of the effective diffusion. In the microbial fuel cell with a membrane, using a reduced proton diffusion depth of the reactor and low-salt electrolyte can increase the anode proton transfer. Miniature microbial fuel cell performance increase may be caused by the diffusion caused by the depth of the reduction [28〕. As the cathode surface of the alkali, with limited buffering capacity of the cathode-electrolyte salt concentration in the low-value can lead to lower cathode potential. Using potassium permanganate as an electron acceptor, due to increases in the cation exchange membrane and cathode, casing-type microbial fuel cell power density can be as high 3987mw/mZ, two-room type than the 34.5 times higher than the microbial fuel cell. Permanganate used the double-pipe microbial fuel cell resistance to 51.Zn, while the two-room-type microbial fuel cells and 1623n.

        From the above results can be seen that the proton mass is a microbial fuel cell of the main limiting factors, it is by increasing the battery's internal resistance to influence the microbial hp pavilion zd8000 series laptop battery cell performance.

         2.3 The oxygen reduction on the cathode

        Oxygen is usually as a microbial fuel cell cathode reaction of the electron acceptor. Have confirmed that the oxygen reduction reaction is a weak microbial fuel cell optimum operating constraints. Commonly used electrode material is graphite, but for the oxygen reduction reaction is weak in terms of catalyst, because it has more than 6.69 / L of dissolved oxygen saturation value. This value is approximately saturated water vapor in the dissolved oxygen concentration of 80%. In order to improve the catalytic activity, usually platinum-modified graphite electrodes, this could make the saturation level of dissolved oxygen increased to 2.0mg / L, the resultant current is the maximum to do more than simply using graphite electrodes 3 to 4 times higher, but its large-scale applications are limited by cost constraints.

        Usually cathode regulator - to increase the oxygen ferrocyanide is also the driving force. In the chemical fuel cells, researchers have examined a variety of materials and their mixtures to replace the expensive platinum cathode kiss〕. These materials include copper, gold, put / drill, key, tungsten and manganese, they use the redox properties of their respective cathode and oxygen in the electron transfer between the indirect. Also studied a 3-valent iron, complex drilling, magnesia coffee〕, etc., as microbial fuel cell cathode materials performance. However, as a microbial fuel cell cathode catalyst, most of them are not as good as platinum and high efficiency. Its effectiveness as a cathode catalyst for the most critical criteria is their affinity for oxygen, which show affinity for the cathodic reaction of dissolved oxygen saturation concentration or K. Value, because the resulting current intensity and the concentration of dissolved oxygen showed a dynamic relationship between horses 3 '1 2:.

         In the enzyme fuel cell [sa〕〕 coffee and microbial fuel cells has been used oxygen reductase - catalase and peroxidase as a cathode catalyst. Aerobic respiratory electron transport system, the end of the oxidase on the molecular oxygen affinity than any known chemical catalyst for the high. Therefore, the aerobic bacteria in the 0.1mg / L of low dissolved oxygen concentrations have the greatest ability to breathe. To this end, the study focus on that as a cathode catalyst on the aerobic bacteria. Cathode biofilm development on improving the overall performance of microbial fuel cells have a significant role.

        Closed-loop conditions, the bacteria formed on the cathode is different from the open-loop conditions, the bacteria on the cathode. In seawater and freshwater sediment microbial fuel cell [3s · 36〕 and man-made water-bed-type microbial fuel cell foot〕 also conducted the same monitoring. Bergel, etc. found in sea water corrosion in the formation of biofilm coated stainless steel cathodes, hydrogen fuel cells do get 0.32w / m, the power density [3s ".

         2.4 electron acceptor other than oxygen

        In addition to the aforementioned ferrocyanide, the permanganate can be used as an electron acceptor. Cathode with potassium permanganate as an electron acceptor (oxidizer) and two-bedroom-type microbial fuel cell can generate a maximum of 115.6mw / m "of the power density, than with ferrocyanide (power density of 25.6 mw / mZ) and oxygen (power density 10.2mw/mZ) as electron acceptor resulting from the high power density, respectively 4.5 times and 11.3 times. This is due to microbial fuel cells permanganate provides a higher open-circuit potential. These results indicate that the cathode reaction also affect the microbial fuel cell applications, an important factor.

         3 microbial fuel cell applications in wastewater treatment

        In wastewater treatment, microbial fuel cell with the existing methods do not possess several advantages. In the wastewater treatment process, the microbial fuel cell can be used as an energy power restoration, addition, in more stable conditions than in aerobic treatment can also produce less sludge.

        The microbes in the aerobic treatment of organic pollutants carried by the use of all the energy, while the microbial fuel cell in the growth of microorganisms in these energy consuming only a small part of most of the conversion to electricity. Assuming a redox potential of 0.32V under the electrons from the contaminants passed to adjoin Sa nucleotide, using oxygen as an electron acceptor end, then the energy of pollutants carried by approximately 1 / 3 is the use of micro-organisms, and the rest 2 / 3 into electricity. This proves that micro-organisms in wastewater treatment sludge from the fuel cell can be substantial savings to address the capital. In different operating conditions, glucose and water half-saturation constant (K,), respectively 79 a 103mg / L and 461 ~ 719mg / L vary. Note these values in order to achieve the required effluent standards, microbial fuel cell to be the most suitable operating conditions of fuel concentrations. Because of this, optimization of microbial fuel cell can not only enhance output power, but also by detecting the quality of effluents to deal effectively with waste water.

         4 Conclusion

        Microbial fuel cell is a kind of repair to use the energy from sewage novel method of sewage treatment. The performance of microbial fuel cells by its resistance to impact, such resistance is the proton mass and the weak cathode caused by the oxygen reduction reaction. Protons in the aqueous phase of the transport rate is very slow, in the hollow fiber reactor to improve the proton transfer between two poles of yin and yang can minimize the depth of the proton transfer, thereby reducing the resistance.

        Cathodic oxygen reduction reaction and the concentration of dissolved oxygen into a unipolar response relationship. Used with a cathode can improve the aerobic performance of fuel cells. Appropriate aggregation of concentrated cathode micro-organisms can be further enhanced oxygen reduction kinetics.

        As the microbial fuel cell operating conditions with a moderate resource-efficient and pollution-free, etc., has given rise to energy, environment, space and other concerns, the current micro-device has been applied to biochemical oxygen demand sensor cafe '. 〕. Through this improvement, greatly enhanced the performance of microbial fuel cells. With further in-depth study, which in sewage treatment as well as other aspects of the application will become an apple 15-inch powerbook g4 laptop battery.

    Mercury-free batteries 8 years behind the interests of the patent is invalid Game








    I believe attention to the cause of the development of China Battery readers still remembers how, early in 2006 in a remarkable message: After careful trial, the Beijing High Court on the new Leader Battery Co., Ltd v. National Patent Reexamination Board to make a final ruling that the case: the trial decision error of fact, the appellant the new Leader's main grounds of appeal set up to support his appeal request to revoke the first-instance ruling and the State Intellectual Property Office of Patent Reexamination Board's decision to maintain the name "mercury-free alkaline New Zealand-shaped batteries" , Patent No. 01,234,722.1 the utility model patent valid. See the news readers sigh of relief, thinking that this means that in China, and the world the battery has an important significance in the history of mercury-free button the dust has settled patent ownership of China's mercury-free battery development will move toward a virtuous development. However, the surprise is that this began in 2002, the final nail on the controversy over the end of 2005, but it is far from over, in the next four years, still in the endless continuity. 8 years, three lawsuits, two to reverse the verdict, but ultimately did not reach a conclusion, should have the benefit of all inventions, but until now hanging in the air, not only failed to bring to the enterprise in the interests of the imagination, but will be a drag the burden of its development, the desolate Jiaoren Nankeyimeng can not help but distraught. Why is a clear structure and determined that a clear, meaning an important inventions will lead to so many intertwined? What exactly has hidden behind this hidden secret that something? Mercury-free batteries is very important to mankind, because of mercury products, including the threat of mercury batteries inside the health of people around the world. It is reported that a New Zealand-style micro-mercury alkaline batteries can be contaminated water is 600,000 liters, equivalent to the amount of drinking water a person's life. Although in 1995, the United States and Europe have issued a ban on the sale of mercury-containing batteries with the relevant provisions, clearly defined, alkaline zinc-manganese batteries can not be added mercury and mercury content of no more than 0.0005% of total cells, but because the world has no technology can produce mercury-free button batteries, button cells can only allow mercury content of no more than 2% of the total mass of the HP PAVILION DV9000 SERIES Battery. The export volume of China's battery has been for several years accounted for more than half of the total international battery. Keeping with international standards, in 1997 the Chinese government issued "on the limitation provisions of mercury batteries" and other series of measures. China's battery industry in a short span of two or three years, research on the adoption of technology to solve the mercury-free alkaline zinc-manganese batteries the issue. However, the face of ever-increasing amount of button batteries, the world without a corresponding solution. In other countries, more than a decade in Japan and the United States, Europe and other well-known battery manufacturers of mercury-free button cell mercury-free overtaken by a large number of studies. However, there are technical problems are not resolved, there is no one company can successfully produce mercury-free alkaline button batteries, resulting in the global market has been the use of mercury-containing alkaline button batteries. Button cell 1 billion each year by the production and use, so that China and the rest of the world people are still faced with the danger of mercury exposure. The battery industry finally came good news. Mercury-free button batteries after numerous failures, the new Leader Battery Co., Ltd was finally in 2000, the initial success. October 3, 2002, the new Leader for the "mercury-free alkaline button batteries" utility model patents successfully been authorized. In order to avoid patent issues encountered in overseas markets in the first time, the company again sync in the United States, Germany, Britain and other EU countries have applied for a number of the patent. As a long time in the world coin battery industry has been plagued by excessive mercury content, although many well-known companies before in the field research breakthroughs, but did not succeed. Therefore, the first one to eat crab new Lida was in the hands of the right to speak in this industry. In accordance with the then estimated that if the day of the production budget of only non-Ersanqianwan button cell, then a month's output is 7-10 million. There is also a month's output of more than billion yuan, the new company plans IPO Leader, developed into a million or more large enterprises. Clearly, this is a huge market. At home and abroad, production is not a new coin battery Lida an enterprise, while facing the new Leader of the invention, apart from the envy of some of our competitors, there is also a trace of worry: because the current New Leader has applied for a patent, it also mean that the only new Leader, or the right to possess the technology to master, then in accordance with regulations, and other competitors can only stay away from this piece of a broad market. In order to obtain this piece of the market, individual infringer, drilling the legal loophole, the use of patent reexamination system, make the patent invalid request, would like to eat the inventor of the patent free of charge. New Leader on the market soon found a large number of simulated mercury-free button batteries, and took away a lot of customers. Even stranger things yet to come. On the new Elite has not taken measures to safeguard their own legitimate rights, infringing enterprises blame to the national patent for a new Committee on Lida patent invalid request. Request to annul the new Leader of patents a company in Guangdong. Cylindrical type batteries that since as early as 90 years in China had realized the mercury-free technology, the new Leader of the button cell shape change though, but the principle has not changed is the battery able to think of the field of technical staff in general and to do technology. The new Leader of the patent is obviously not creative. An application declared the patent invalid. In order to give in is the new Leader in 2003, in March, infringing the company's head has engaged the person in charge to meet the new Leader. Stress required to share the patent with the new Leader, otherwise the application for a patent invalid, to become public knowledge technology, which means that any one company can be involved in this market. "Your patent is an antique vase, this is very valuable antiques, you cooperate with me, free me half of the value of the antiques are still, you still have half, but if co-owned with my, I have the ability to play this antique broken, it is not worth a penny. " Each other's unreasonable demands and threats of new Lida was immediately refused, as the new Leader firmly believed that his inventions will be patent law should be protected. However, the result was unexpected. In May 2004, the State Intellectual Property Office, the Patent Reexamination Board with a new patented product Lida button cell structure and has no substantive difference between the structure and its mercury-free alkaline manganese COMPAQ BUSINESS NOTEBOOK NC4000 Battery technology and cylindrical similar as the basis, so out a declaration of "mercury-free alkaline button-shaped batteries" utility model patent is invalid decision. The outcome, the new Leader's dissatisfied, then to the Beijing Municipal No. 1 Intermediate People's Court proceedings, the Patent Reexamination Board to court. However, the Court of First Instance is still admissible criterion of the Patent Reexamination Board made a decision to maintain the patent invalid. Then again stress patent infringer of people have signed an exclusive patent license contract for free, such as signed by the infringer also have this patent, can guarantee that the patent valid, do not sign the formal null and void. Patentee refused, then hit the Beijing High Court lawsuit. After careful trial, December 20, 2005, the Beijing High Court made final: it removes the first-instance ruling and the State Intellectual Property Office of Patent Reexamination Board's decision to maintain the name "mercury-free alkaline button-shaped batteries", Patent No. bits of the utility model patent for the 123,456,722.1 effective. A dramatic scene appeared, in the High Court of Final Appeal ruling, the infringing party to launch a second invalid undo the action, but the applicant changed to the secretary of the company's CEOs. So in the next three years, the new Leader had to repeat the previous process until August 22, 2008 the Beijing Municipal Higher People's Court again rejected the Patent Reexamination Board, as well as a Beijing Intermediate People's Court's decision. China has an old saying called Shibuguosan. However, it appeared to be very persistent opponent. In 2008, the infringing party has repeatedly brought back to the Patent Reexamination Board invalid. Shocking in June this year, the Patent Reexamination Board to determine the third time the patent is invalid. Lida that the new mercury-free technology is the cell area of general and technical personnel in Japan, the technical basis of unsuccessful easy to think of technology, there is no creativity, now the new Leader has been to the Beijing Municipal Intermediate People's Court proceedings. As a blank to fill in the world, to bring the Gospel to the world of environmental protection, giving Chinese companies opportunities invention, it has experienced eight years of marathon litigation. Year after year, the lawsuit should have not only failed to bring benefits to the inventor, but has become a burden at all times Jiaoren lazy. At the same time, in the endless litigation under the influence of the development of enterprises greatly damage. Due to the adverse effects of litigation, making the market a new image of Lida affected, more than 50% of orders have been infringed away, product prices fell more than 30%, resulting in the profit is very low. The new Leader of the dream do not know when the listing can be achieved. The competitors have a new Leader malicious invalid patents obtained in the course a lot of benefits, the business seems to have done in full swing. In an appearance of legitimacy from the patent is invalid case, we can not help but send questions: Who will protect the rights of the inventor? For this case, some experts believe that market competition is a double-edged sword, bringing vitality to the market at the same time, it also brings risks. Without the constraints of the disorderly competition will not only upset the market, and even the market will bring disaster. And because a number of legal measures, imperfect, leading some people have an opportunity infringement, in order to seek their own selfish desires at the expense of relationships and the use of means of coercion to eat the patentee's patent, really daunting! Battery industry believe that the Chinese a leading global, the world's major contribution to environmental protection SONY VGP-BPS9/B Battery is a patent can not be established to make the reasons for invalidation of the three-day decisions, leading to ownership of independent innovation of enterprises received only eight years, the patent is invalid Dabu Wan lawsuit, infringement, unless the long-term large-scale infringement, even more terrifying is the franchise you want to eat like triad means, so that one would have a bright future development of enterprises, the gradual loss of competitiveness. SIPO Patent Reexamination made by members of the three-day review of the decision null and void, you can act against each other with the Court, but not appropriate departments to monitor, and now there is corruption in society, culture, hope that the Central and the State Council leaders will pay attention to this innovation intellectual property rights have been three-day non-normal conditions is invalid, Save China's own innovative enterprises.

    Environmentalists intentions of the proposed classification variable garbage wastes into








    Open a new pair of socks, how to deal with the remaining packaging?



    The life of a common scenario, in fact, the classification problem of litter. Take a look at the practice of Zhengzhou environmentalists, you may be surprised to find there. If you agree with their approach, please be like them, bit by bit from the start in life.



    ■ Chinese Commercial News reporters Zheng Xiao and Qian Gaoyun



    Depressed



    Divided into many different types of waste eventually mixing the



    Yesterday saw the Chinese Commercial News of used batteries on the way out of the reports, Mr. Zheng Zhouzhang call the hotline, said green living, waste batteries hidden behind the fact of a larger problem, it is trash.



    6 years ago, released a set of data so impressed by Mr. Zhang, China's municipal waste output up 200 million tons, and each year to 8% ~ 9% growth rate.



    200 million tons, this huge number, so that Mr. Zhang Dunsheng a fear of being surrounded by garbage.



    Since that time, he would pay special attention to the litter problem, and insisted on waste separation at home. The kitchen to produce food residue, never mingled with the other IBM THINKPAD R31 SERIES Battery.



    However, Mr. Zhang depressed to find that, in the final good type of garbage bags, only a trash mouth "shelter" them, he specially marked garbage bags on the good types, placed in bins next to garbage trucks, etc. come, or a pot of Stew it, all thrown on the train.



    The streets of recyclable garbage Daoshi points can not be recovered, but the other cleaners to collect when they are brought together in a very intimate.



    Mr Cheung said: "Now, I mention a waste separation at home, the wife and kids would laugh at me, said I was enthusiastic about."



    Action



    Socks, bags classified into three types of litter



    Mr. Zhang's distress, Friends of Nature group Xiao-Jing Yang, Henan has also shared his feelings.



    But she said that we can not decide on a city's waste disposal process, then start with themselves, to minimize waste generation.



    "It's nothing difficult, that is, paper, plastic, metal and other junk store different categories." Xiao-Jing Yang said, we can effectively reduce the amount of garbage manufacturing.



    Looked at the simple things, but must pay attention to all aspects. YANG Xiao-jing, for example, she was apart a pair of new socks, trademarks, will be put into paper trash baskets, and plastic supports, then put into plastic bags, the regular use big iron clamp although only a grain of rice would be sent to metal trash baskets.



    Try



    In the domestic vermicomposting garbage



    Separation of recyclable waste, the rest of the garbage on the fling do?



    YANG Xiao-jing can be reconciled to that, she played a domesticated earthworms - the living room in her home a corner of them the three plastic barrels of "garbage", which can be seen from time to time of a reddish-brown flesh Hu Hu earthworm peristalsis.



    "Do not belittle these worms, they eat garbage, and Latin America were all 'black gold', is able to effectively increase soil fertility, organic fertilizer." Said Xiao-Jing Yang.



    Xiao-Jing Yang said that in the municipal solid waste in a larger eco-environmental hazards and can not be recovered, that is, left the kitchen garbage.



    The peel, leaves, leftovers, etc., are earthworm like delicious, after they break down, the pollution of the environment of the waste becomes organic fertilizer to protect the environment.



    Raising earthworms in the process of recording a large number of diary YANG Xiao-jing, understanding the living habits of earthworm. Also wrote an essay on earthworms fairy tale "a worm's monologue" has invited an illustrator of fairy tales with maps, links and publishing houses are now publishing thing.



    "I hope that more people, especially children about earthworms, it is best to earthworms as pets at home to support." Xiao-Jing Yang said.



    Vision



    Hoping to find a community to work together to support earthworms



    Today, Xiao-Jing Yang is leading on a project - "Love Me Green" friendly ACER ASPIRE 3050 Battery.



    Xiao-Jing Yang said: "What we want to find a community co-operation, emphasizing interpersonal harmony here between man and nature in harmony."



    A breakthrough is to start with waste separation began.



    "From our team more than three months of practice, this earthworm is indeed skilled handling of garbage, if the entire community can be adapted to local conditions to support earthworms handling garbage, half of the domestic waste will be able to be digested in-situ treatment." Xiao-Jing Yang said, they want to, residents raise earthworms in the family, community green spaces in the outdoor side of raising earthworms, two lines go hand in hand, common to urban living garbage "war." At present, the project team already has 2.5 acres of earthworm breeding base.



    Not only that, they also plan and the community to explore the battery lease, environmental education and other projects.



    "However, these also are the ideas that we are applying for project funding, but the most needed, is to find a community willing to cooperate." Xiao-Jing Yang said, trash, they are actually misplaced resources.



    ■ News Background



    0 years of struggling, Zhengzhou trash



    Started in 1999 in Zhengzhou



    Speaking of garbage classification, Zhengzhou Municipal Bureau of Environmental Sanitation Management Law Enforcement everywhere longer than the courtier very helpless, "across the country have not been successful in precedent."



    He recalled trying to trash our province the tortuous course of:



    In 2000, the Ministry of Construction choose eight cities across the country as a pilot project to promote waste separation. Zhengzhou, although not in the eight cities in the list, but early step to set off a trash propaganda.



    October 26, 1999, Zhengzhou City, was held at the Greentown Square, "not to pollution into the 21st century" public good publicity on environmental protection, calling on the city to recover the used batteries to make a breakthrough, and gradually to promote waste separation.



    After the trash promotional activities continued in Zhengzhou. In early 2001, zhengzhou shi guan cheng North Street offices were established under the US-led pilot, a number of trash containers in the office under the jurisdiction of the community first "posts." At present, Zhengzhou City, the roads are put next to the classification bin.



    Can be the first line of the road, at the courtier gradually feel "walk by." Up to now, in the waste classification, our country did not become immortal repair of a city.



    The three major stumbling block highway



    Garbage classification difficulties, difficulties in the courtier to sum up as follows: no protection of the laws and regulations, classification standards inadequate, the investment of the main three areas is not clear.



    Throughout the country there is no specific legal protection, depends on the people to voluntarily and consciously to serve their refuse, which test the public's "consciousness."



    Classification criteria of the imperfect, not only members of the public scratching their heads, even in the courtier is difficult to choose.



    Trash will be collected by the end of a mixture of mixed waste disposal, rather classified waste disposal must also require large investments. "Yes the government pays the bill, or take the market-oriented path of success in China has not set a precedent." In his view, Zhengzhou Category Sansibaiwan human waste disposal needs of the organization of specialized sorting, "This huge expenditure is also definitely better than the road cleaning fee very high. "



    Screening look before throwing garbage



    In the waste separation has not formed the premise of the social system and norms, "we are currently only trash hopes to enhance the public awareness." On the courtier said.



    Yu advised the public to deal with the litter courtiers before a round of sorting. Waste paper, plastic bottles, glass bottles, scrap metal, clothing, timber, and the like should first be screened out, sell recycling personnel, this could make some Dell INSPIRON 510M Battery recycling.

    U.S. Scientists use nano-coating made of paper-based battery








    【China Coating Online News U.S. scientists at Stanford University, made the use of nanotechnology-based fast-ordinary office paper for ultra-lightweight, flexible battery or super capacitor. Related Articles published in this week's U.S. "National Academy of Sciences" on-line edition.



    Materials Science and Engineering at Stanford University assistant professor Yi Cui (phonetic) said it would provide a paper covered with silver nanowires with carbon nanotubes and coating raw materials can be turned into a good conductive energy storage device. He said that these nano-materials with a diameter of a small three-dimensional structure, which enable nano-materials, dressing more closely attached to the surface of the paper fibers, making a more durable battery or super capacitor. This paper can achieve a super capacitor, or 40000 times charge-discharge cycles, or at least comparable to the number of lithium battery charge and discharge an order of magnitude higher. The nano-materials, more efficient charge transfer can also make it more advantages than conventional capacitors, the effect would be better.



    Research team tried a plastic substrate made of nano-materials for energy storage devices, dressings and paper and as a close bond resistance, this paper as the base of the battery than the battery more durable plastic substrate. More importantly, the paper batteries are not afraid of crumple and fold, or even their being immersed in acidic solution, it will not affect performance, but also to effectively reduce production costs.



    Cui Yi, said paper-based flexibility to achieve a variety of intelligent applications, such as brushes can be such a high electrical conductivity of the dressing smear on the wall above, and its fast becoming a large-scale energy storage device. When it with light-emitting diode (LED) and so connected, it can provide sufficient electricity for the LED source. In addition, this technology can be used for power distribution networks, will generate surplus electricity at night up centralized storage and ease pressure on electricity during the day time peak. In the wind farms and solar energy storage systems can also achieve similar applications. It is worth noting that the paper super capacitor may also be used to electric or hybrid vehicles into. Two kinds of cars depends on the rapid transmission of electricity, while the paper capacitor high ratio of surface area and volume, which created its presence in the automotive application of a great advantage.



    As a leader in nanotechnology, the University of California at Berkeley professor of chemistry Peidong Yang, said the technology's ability to achieve in the short term commercial potential. He believes that this technology will not just be limited to the field of energy storage devices, and its low cost and flexible properties make it fit with any electrical device electrode, the prospects quite broad. More importantly, we can use the most common life of the paper as a substrate, through a simple process,  apple ibook g4 14-inch series laptop battery made of conductive features strong, which will fundamentally nanotechnology will be linked with people's daily lives.

    Mengzi 39 battery plant to die from Xing








    51 years ago, the Red River state's first battery factory - Mengzi Mengzi battery factory was established in 1995, changed its name to 999 Battery Co., Ltd. (hereinafter referred to as 39 battery factory); 10 years ago, a preliminary stage only 15 employees enterprise development, production value of nearly a billion, more than 2,000 employees in Mengzi County pillar industries. 7 years ago, the economic benefits of the national industries have been Wenju second loss of the enterprise began to appear; Last year, the 999 cell mark of 27 million to Hangzhou, a salesman who cheapens the price of a battery factory. In November this year, once a brilliant 999 Battery Co., Ltd. formal entry into bankruptcy liquidation proceedings. From the factory to close down a full 51 years, a former battery factory 39 - died.



    Oida memory scenes in the booming



    December 5, sunny, in front of car to drive to the streets, stirring up a dust. 39 battery plant defense Laoxiao (a pseudonym) to defend the room sitting inside drinking tea, when bored to hand, looking through the table of old magazines. Basically, he need not worry about their own security work, because this time there will be no people to the battery factory.



    Laoxiao not old, only because he felt had been done in the yard inside the 20 years, suddenly felt old.



    Since November of this year, 39 battery factory entered bankruptcy liquidation proceedings, the original factory having more than 2,000 employees, leaving more than 40 staff, to do to defend the Lao Xiao is one of them. "In order to give the workers made cost of living, yard equipment inside basically sold out, and had not left anything." Lao Xiao said.



    Oida this year, more than 50 years old, still living the single life. Be able to write articles, he left the yard in 2004, later, in Mengzi County Economic Development Zone of a Secretary of finding a job.



    As Mengzi local educated youth, the end of 1978, Oida into 39 battery factory work, entered the shop at the time involved in battery production. He said the battery factory was April 20, 1958 established by the beginning of the plant is built, rented a 200 sq m of houses to do factory workers is only 15. Equipment is also very simple, there are three Wagang, a Otikpo table, a cup and a voltage meter. The first director of TAM Chi-sheng to bring everyone over 36 times trial, and finally made into compaq armada 7400 laptop battery.



    In 1964, the battery factory in Guangzhou to introduce the technology Wing-yue battery factory and some equipment to play horizontal playing electric batteries to replace the manual, mechanized production and gradually replace the manual, R20-type batteries fully closed officially come out this year, " 999 "brand opened officially registered trademark.



    Due to various reasons, 39 battery plant development has been relatively slow until the last century, 80 years, the government's support, yard suddenly the fire, and an annual output of the battery to reach 33.04 million. In 1989, the factory covers an area of increase of more than 40,000 square meters, employees reached 1055 people, producing batteries 102.9067 million, the products are sold inside and outside the province, hundreds of counties, cities and export in Vietnam.



    The most glorious time in 1995, the then renamed as the 999 Battery Co. battery factory, when workers have more than 2,000 people, more than 200 million batteries annually, with nearly billion in business output.



    "In the 39 battery factory jobs, you are very busy every day." When asked why he has never married, Oida said, when every day is busy, and basically had no time to Qupei his lover, breaking up is too normal.



    The first technological transformation and enterprise restructuring



    The last century, the early 90s, vigorous state-owned enterprise reform and sweeping river north and south, which also includes the reform of enterprise technology. Mengzi County when he was growing Yao Lee, said the then 39 battery plant is Mengzi's pillar industry, in 1992, the provincial leadership's support, battery factory to increase production capacity expansion of the technological change, the introduction of a batch of equipment from Shanghai . The total investment is 35.06 million yuan, annual production of 200 million batteries technical transformation project implementation, fully completed and commissioned in 1995. The then Governor He Zhiqiang who have hp f4486b laptop battery factory inscription: "Development of high-tech, bold and open up domestic and international market."



    Oida at that time have been assigned to participate in technical innovation. For that technological transformation, Oida, said the equipment was all imported China-made equipment, the production of the batteries is also a traditional paste-type zinc-manganese dry batteries, such batteries generally used in flashlights, is a large battery. This time, the results of technical innovation has also been named the State Economic and Trade Commission Award for outstanding technical innovation. First technological transformation, the 39 battery plant's annual output suddenly increased to 200 million, though this industry is low value-added industries, and each cell's net profit is only a few cents, but the volume up, the benefit comes on Therefore, when the output value of nearly billion business.



    Oida said that in this technological transformation before and after the 39 battery factory received many honors, 1992, 1993, 1994, for three consecutive years was voted as a hundred enterprises in Yunnan Province, in 1994, economic ranks second in the industry, star enterprise attracted national frontier Vietnam, Burma, Japan, Laos and other countries to visit friends, the products also sell well in domestic 16 provinces and cities, are exported to various countries in Southeast Asia and Africa. In 1997, the "999" brand battery has been selected as the first province of Yunnan, brand-name products, access to national import and export right. In 2000, export sales reached 39.4 million yuan.



    For the first technical innovation, a former battery factory engineers packet 39 has its own strong views, packet-keung said the first technical transformation from a business point of view, because the output is indeed a substantial increase, so that businesses look very prosperous, but the From a purely technical point of view, the first technological transformation was not successful. Because the first technical innovation is the use of traditional craft production of traditional batteries, science and technology content is very low.



    Technological transformation was successful, but in the technical transformation of enterprises before and after restructuring have not been so lucky.



    Mengzi County, former deputy head of MAO Cheng-wei said at the time of the restructuring program, state-owned assets, 51%, while the shares owned by employees of the factory 49%. When most employees are unwilling to shareholders, in order to be able to restructuring continues, the factory has taken from each person's wages were deducted money paid for shares of the approach, in disguise forced employees to buy shares. In his view, the 1995 restructuring due to the prevailing level of policy conditions and restrictions that significantly restructured with the transitional nature of the left tail of the old system, strictly speaking, is an incomplete conversion.



    The second technical innovation fatal



    For the first time after the reform, corporate suddenly fire up, but with the development of the times, the original equipment behind the competitiveness of enterprises resulting from lack of highlights. The most intuitive is that with the popularity of pagers than 1, the battery 5, a small, 7 batteries surge in market demand.



    Package-keung said the end of the century, pagers most popular, and sony vgp-bps9 laptop battery plant to produce only applies to No. 1 flashlight batteries, in order to seize the market, 39 rocket battery factory in cooperation with South Korea decided to introduce a set of South Korean production line. This is the 39 battery plant's second technical innovation. In 2002, a total investment of 37.95 million yuan, annual production of 45 million mercury-free alkaline battery technology projects in operation. "It is this time, technical innovation has accelerated the death of 39 battery factory." Package strong view.



    "The first time a total investment of technical innovation nearly 4,000 million, technological transformation of the money is borrowed, the technological transformation after the enterprise is profitable, but the first time technical transformation of the debt is not repaid, immediately proceeded to the second technical innovation in a short time the two technical transformation depleted 39 battery plant family belongings. "a worker who requested anonymity told this reporter, the second technological transformation started in 2002, but the project from start to final production , for a whole spent three years, three years is the golden age of trumpet battery sales, to put into operation in 2005 when the pager out of rivers and lakes, cell phones have been popular, trumpet sale of a sudden the battery into a bottleneck period. Year after commissioning of new technology projects sales of 10 million, only the project design capacity of 45 million a quarter, the average annual working hours in less than three months and spend huge amounts of money from South Korea to introduce the production line is idle, the staff jokingly its is "Sleeping Beauty."



    Pale, self-help measures



    39 battery factory in 2002 for the first time at a loss this year, the second technical innovation has just begun a sharp decline in the effectiveness of the entire plant, the production line the vacancy situation, all workers had to implement a rest rotation. Most of the workers can only work six months a year, the staff's basic salary can not be paid on time, only to work within a period of time to receive a number of attendance wages.



    "We plant the burden too heavy, a total of more than 2000 staff numbers, except for temporary, full-time staff only 1,500 people, while the retirees, there are more than 600 people, the real work, only a few hundred people." When talking about yard just down situation, Oida said that in his opinion, this is one of the reasons closure yard.



    In 2003, in order to save themselves, 39 battery factory has set up a real estate development company, and purchased a piece of land, but the development phase, funding became a problem, Left, under real estate company had to reluctantly part with, transfer of land to another property developers. Although the process of changing hands earned 300 million yuan, but this is a serious loss for the 39 battery plant, the same as in the drop in the bucket.



    April 30, 2005, 39 battery factory completely stop production. In addition to all the workers to stay more than 40 people, the other all the laid-off. Some people moved to other plants, some into the government agencies, there is no technology or expertise to the living conditions of people worrying and can only receive a monthly 156 yuan living expenses. "The money is even lower than the minimal needs Mengzi." Oida said.



    Late last year, 39 battery plant his own mark of 27 million sold a battery factory in Hangzhou, but the battery factory for the 39 people who, now 39 batteries, and they have no relationship.



    The Rise and Fall



    Established in 1958, rented 200 square meters factory houses do, employees 15 people, equipment: 3 Wagang, a Otikpo table, a cup and a voltage meter, 36 times trial made four batteries



    1964, R20-type battery officially come out fully closed, "999" brand opened officially registered



    1989 factory covers an area of 4 thousand square meters, employees 1055 people, producing batteries 102.9067 million, the products are sold at home and abroad



    Economic sectors in 1994, ranks second in



    In 1995, more than 2,000 employees and an annual output of more than 200 million  acer batcl50l laptop batteries, with nearly billion in business output



    1997 "999" brand battery has been selected as the first province of Yunnan, brand-name products, the right of access to national import and export



    Export sales in 2000 reached 39.4 million yuan



    A loss for the first time in 2002, the production line of the vacancy, workers are forced to undertake a rest rotation



    April 30, 2005, the complete shutdown, more than 40 employees stay, the rest of laid-off



    The end of 2008, 999 cells at 27 million mark to the salesman who cheapens the price of a battery factory, Hangzhou



    In November 2009, formally entered bankruptcy liquidation proceedings



    ■ Follow-up



    "39" collapse in the end what causes it? This problem, each person's opinion.



    What causes a "39" closure



    Marketing mistakes trademark does not protect the



    39 battery factory in the marketing department for many years Mr. Chang said the company in marketing there are a lot of mistakes. For example, he said, 1, 2 batteries this should be targeted at the rural market, 5, 7, the battery should be targeted in this town, 39 battery factory has not targeted their marketing policy. Preferential policies for the various regions are not the same, the wholesale price and dealer profits are not the same, resulting in the phenomenon of Chuanhuo more serious once the market situation is very chaotic.



    This one in particular, export, 39 battery factory's products in addition to domestic sales, it also exported to Southeast Asia, while exports were once the company's biggest profit source, the most important is the Laos, the largest export when the battery more than 7000 million . However, in August 2004, 39 Battery trademark in Laos have been maliciously registered by, and apply for Laos's domestic intellectual property protection for the record. After the trademark is registered by the Lao government below, to prohibit sales of 39 batteries in Laos, since trademark does not protect well, 39 battery factory that has 20 years to lose the Lao market.



    Technological transformation led to a short interval of the two higher operating costs



    Oida considered to be the failure of technical innovation, in their view, because of the two technological transformation interval is too short, too much capital investment in technological reform, and the two technological transformation is not considered a real success, the benefits of technical innovation can not compete technological transformation is proportional to the input, resulting in higher costs of business operations and ultimately lead to failure.



    The second year technology projects can not put into use



    MAO Cheng-Wei believes that state-owned enterprises system eventually led to the death of 39 battery factory. In their view, 39 Battery Factory is a state-run old plant, the largest proportion of state-owned capital, the first conversion did not change completely, left a number of problems, to the development of enterprises brought some hidden dangers. In the second technical innovation, if not too much red tape, if we can not put into operation during the year, then the 39 battery factory to catch up with the sales of the golden era, perhaps this company would not have come to such an extent .



    In fact, the clearest reason for the collapse of the current 999 Battery Co., Ltd., Li Zhizhong, the reporter rang his phone, but he refused the interview.



    This year in November, dell inspiron 1200 laptop battery factory has entered bankruptcy liquidation proceedings, Mengzi County People's Court accepted the 39 battery factory has been placed on file the application for liquidation bankruptcy. In fact, the most prosperous time of 39 battery factory, domestic well Deer, South-fu, Duracell batteries and many other brands compete with each other. Now, 39 bankruptcy, and Duracell have lost sight of Deer are rarely able to see. Only the strongest Nanfu become peers. It is understood that Nanfu battery plant is established, the registered capital of only 2 million yuan.

    A substantial decline in sales of new national standard, "knocked" electric car industry








    Currently on the market more than 90% of the electric car more than this standard, which means that more than ten days, the majority of electric bicycles will be on the license, drivers need to test driver's license.



    Electric bicycle motor vehicles to be on the Road? National Standards Commission recently released the "electric car new national standard," caused a great stir.



    The State Bureau of Quality Supervision Management Committee under the National Institute of Standards recently released the "electric motorcycle and electric mopeds general technical conditions" will next come into operation on January 1. Click here to national standards, "vehicle weight of 40 kg or more per hour over 20 kilometers of electric bicycles, electric motorcycles would go into the light or the electric motorcycle, classified as motor vehicles category." According to industry sources, currently on the market more than 90% of the electric car more than this standard, which means that more than ten days, the majority of electric bicycles will be on the license, drivers need to test driver's license.



    "This is a standard introduction, the sales dropped by 50% or more, dealers are afraid to pick up the." Luyuan Electric Vehicle Co., Ltd. Chairman and Director of the Office Ding December 7 to the "Daily Economic News" said.



    If you press the standard implementation, in addition to 120 million electric car owners affected, the more than 2,000 electric vehicles manufacturing industry may face a new round of reshuffle. Professional Committee of China Bicycle Association, Bicycle chairman Lu Chin-lung to the "Daily Economic News", said motorcycle license in accordance with enterprise access threshold, currently more than 2,000 electric cars in the vast majority of SMEs are enterprises not up to standard due to be forced to closed.



    It is understood that the association has been the standard commission to submit report on suspension of implementation of the new national standard, as of December 7 press time, the national standard committee is also the absence of relevant position.



    Dealers did not dare pick up the



    "Now young man riding a bike can achieve this speed, then low, and who buys it?" An electric car dealers said.



    A certain brand of electric bicycle vendors, Yang is also very fears, he Haidian District, Beijing Xiao Xitian near a larger store, the average monthly sales of 300 units or so. "Now people are asking to buy a car, you have to do on this car brand ah? Driver's license or not ah?" Yang the boss of the "Daily Economic News" said that he did not know how to respond. To be sure, ask the majority of people who do not choose to buy, Yang owner, said this month, sales dropped by at least 20%.



    December 7, a number of electric car companies interviewed said there have been significant effect on sales. "This is a standard introduction, we are affected by large-sale terminals, has clearly reflected in the end had a small season, but late in November, from the sale of terminal feedback situation, the sales dropped by 50%, and this is a conservative estimate. "Ding December 7 to the" Daily Economic News "said the general lack of consumer confidence, are waiting to see, basically no longer marketable, and dealers did not dare pick up the dell inspiron 9200 laptop battery.



    Lu Jinlong December 7 revealed that at present the Association has already raised the suspension of the implementation of electric vehicles for the new national standard related to report to the National Institute of Standards Management Committee, has not yet answered.



    20 km 40 kg into a bone of contention



    "Every day I receive dozens or even hundreds of phone companies to inquire about the new standards of electric vehicles, corporate sales were a significant effect, the new standard for the industry a big shock." Lu Chin-lung to the "Daily Economic News" told reporters.



    "Electric cars are the new national standard" refers to the National Standards Board recently released the "electric motorcycle and electric mopeds general technical conditions", one of the most concern is the "speed of 20 km, 40 kg." It is understood that the implementation of China's electric vehicle industry standard is: Speed less than 20 kilometers per hour, weighing not more than 40 kg. National Standards Commission in a recent paper also indicated that, the electric motorcycle is a motorcycle, "electric motorcycle in accordance with the standard motor vehicle management."



    Have "permanent" Road bicycle shares of listed companies (600818, SH) Deputy General Manager Yuan Zhijian December 7 on the "electric car new national standard" accept "Daily Economic News" interview, "said the electric cars currently on the market more than 90% in excess of 20 kilometers per hour, weight 40 kg. If the implementation of the new standard, most of the electric car will be driven motor vehicles Road traffic will be more confusion and can not imagine! "He's worried that this will lead to industry shocks.



    "This standard has been overtaken by events." Professor at Tsinghua University, China Electric Bicycle Association's chief specialist marques Long on the "Daily Economic News" reporter, the new national standard used by the standard in 1999, when the 24 volt 10 Ah lead-acid batteries with meet this requirement. At present such standards can not meet public needs, "to recharge a battery only running 10 kilometers, Who will buy?" Therefore, it is a lot of electric bicycles with 36-volt 10 Ah battery, body weight is completely over 40 kg.



    If the new national standard to be implemented, but also accord with the public's travel needs, lead-acid batteries can only be replaced by lithium batteries. Gui-Long Obviously this does not agree, "lithium batteries is recommended growth stage, there is no large-scale commercialization, only a few enterprises are small-volume pilot production test marketing the material may also need to be imported." He believes that security problem has not yet completely resolved, the new national standard, if implemented, may lead to the development of lithium battery industry, the blind, quite a mixed bag, to the safety of electric bicycles to bring hidden dangers.



    Motorcycles, bicycles competing interests?



    Why is the introduction of a national standard would lead to such intense controversy in the industry? Lu Jinlong that, because participation in the formulation "electric motor conditions" of the unit does not have wide representation, saying it represents the strength of the "motorcycle industry."



    He said, "We are drafting amendments to the national standard of electric bicycles, the purpose is to relax some standards. It should wait for us after the introduction of new standards, with the new standards. However, electric motorcycles and electric light standards are pre-empt the introduction of a motorcycle , and 'blocking' of the electric bicycle industry, space. "



    It is understood that participation in the formulation of this "new national standard" is that China Automotive Technology and Research Center under the National Automotive Standardization Committee, and according to industry sources, the time to participate in drafting the standard, and there is no mainstream enterprises to participate in electric cars. China's largest manufacturers of electric cars electric vehicle Co., Ltd. Jiangsu, the new Japan in December 7 to the "Daily Economic News" reporter, said they did not participate in the discussion of the new national standard. Gui-Long told reporters that the new national standard electric motor is driven by the motorcycle acer aspire 3050 laptop battery, as the electric car industry expert, he did not participate in the standard work, "the drafting of 11 units are not now, electric bicycle industry, mainstream business." Gui-Long that the standard-setting parties and therefore the lack of real understanding of the situation.



    Analysts said that "national standard" of the dispute is actually behind the motorcycle and electric bike business enterprise game. Statistics show that in 2008 the national production of electric bicycles to apply for business licenses to 2394, including more than 100 is the original motorcycle manufacturers. The new standard, once implemented, the remainder of a large group of more than 2,000 small and medium enterprises will face difficulties.



    The new national standard for the electric car controversy, December 6 evening, GB Committee on the electric motorcycle standard release notes of the situation, said, electric bicycles and electric moped is a distinctly different characteristics of the two products. Approved in 2009 "issued by electric motorcycles and electric mopeds general technical conditions" and four standards by the National Development and Reform Commission, the public security departments have agreed to cross-tubes, etc., according to the national standard system (Revised) to provide procedures for the National Automobile Standard Committee Motorcycle Branch will be consulted extensively on the basis of the relevant scientific research institutes and experts from many years of repeated arguments developed.



    However, the description, Lu Jinlong believe that the note did not explain the relevant focal point, "that was not much."



    Or to trigger a wave of industry restructuring



    Under the new standards, more than 20 kilometers per hour, weighing over 40 kilograms of electric vehicles will be included in the scope of motorcycles. According to the latest requirements of the Department of Public letter to get motorcycle license, companies must meet the project's total investment shall not be less than 2 million yuan, investment in fixed assets (excluding intangible assets such as land use rights) shall not be less than 80 million yuan, production and R & D investment in equipment shall not be less than 2000 million yuan, registered capital of not less than 80 million yuan.



    It is understood that there are more than 2000 domestic electric car manufacturers, but most of them small and medium private enterprises. Lu Chin-lung said that the vast majority of electric car companies not meet the standard, which means that most of the enterprises will be forced to close.



    December 7, Jiangsu Electric Vehicle Co., Ltd. Deputy General Manager of the new Japan, Hu Gang, spokesman for the "Daily Economic News" that the introduction of the new national standard, not only will bring about 100 million people to travel changes, the Electric car maker will also have a re-shuffle.



    However, he believes that the new national standard for the company, the pros and cons Jieyou. The new national standard will help standardize the industry, but better to listen to public opinion and the electric car industry big business proposal to suspend the implementation. According to reports, the company is actively under the new national standard for access, while improving the research and development, production and crafts.



    Judging from the current foreign similar standards, the European electric bicycle speed limit is 25 km, the United States for 32.18 kilometers, Japan is 24 km, South Korea is 30 kilometers more than the Chinese standard. Reporter in the interview, several companies said that the proposed new standards in China in the 30 km speed limit more appropriate.



    Electric cars to be implemented the "new national standard" is it mandatory? Experts said that despite the "electric motorcycles and electric mopeds general technical conditions" the national standard is a recommended standard, but if the Ministry of Public Security as the laws and regulations to implement the goalkeeper will have the same mandatory.



    December 7, this reporter contact the State Bureau of Quality Supervision, the official said, there have been questions in the national standard GB committee to explain himself. December 7, this reporter to call the national standards committee responsible for this standard industrial one, while the person should contact the department responsible for Policy Research, and December 7 of the Policy Research Office ibm 02k6699 laptop battery has been in a state of no one answered.


    9:37 am
    Phone tapping in the end how God?








    Recently, with anti-corruption famous Hong Kong Independent Commission Against Corruption (ICAC) monitor was wrong with the phone to listen to the target audience was exposed, allow people to disguise how much insight the cell phone tapping is easy. Earlier, the Hong Kong film "The Lives of Feng Yun", the lines "In fact, every person has some eavesdropping devices, our GSM jamming devices, mobile phone number as long as the input target, it can intercept the call to hear each other, even if the other party does not start , as long as the battery is not removed, like to hear, "to allow users to eavesdropping on the phone more" doubts. "



    In addition, the mother card can be copied without SIM card mobile phone tapping anyone's phone, GSM jamming devices, undercover software after another, but also to allow users to talk about "mobile phone bugging" pale. For a time, on-line to also renewed speculation over again. Well, now travels the phone tapping is really hot so on? However, whether magical or not, pass the HKMA regulatory bodies to remind the members of the public listening to others without  sony vgp-bps3 laptop battery is definitely against the law.



    GSM jamming devices to intercept calls?



    The film "The Lives of situation", the eavesdropper Daniel Wu jamming devices by using the GSM, as long as the input target mobile phone number, you can easily eavesdrop. The search on the Internet, found that "eavesdropping situation," began playing, there are a lot of people to sell "GSM jamming devices," bid was not high, a set of three or four hundred yuan. So, in reality, so eavesdropping can be achieved?



    "In theory, sure can be achieved." Communications technology source said. In today's cellular mobile communication system, each base station using radio frequencies do not exceed a few hundred. If you want to eavesdrop whose cell phone signal can be at one with the same cell, and then be able to receive the cell base station is responsible for all the signals, and "cracked" it. Target all the information issued by the handset, including its number, are those where a digital signal. Eavesdropper needs to be done, that is, from a bunch of "1" and "0" find the required information.



    Of operators have revealed that, in fact, they have now been authorized by the relevant bodies may lawfully monitor the use of certain equipment that can be achieved. Business opportunities in the operating room, monitoring can be achieved without blocking the signal.



    Identification Results: GSM jamming devices, an average person can afford, the general electronic market, there can be no public sale of such products. In addition, GSM jamming devices, the effect is not so miraculous, it can only signal in the same base station within the coverage area played a role in intercepting the signal, if the goal is far away from, or in a different base station coverage, would be difficult to fulfill the function it has.



    "Undercover software" really can become an undercover?



    In the GSM jamming devices, touted at the same time, "undercover software" came back. The software is also called cell phone spyware. This software is similar to computer virus program, once installed in cell phones, you can run automatically in the background, save the user's call or text message records, and even remote control was carried out eavesdropping.



    Alleged that once the phone is equipped with the software, shutdown no use, mobile phone even when turned off, but the same still with the wireless base stations for signal contacts.



    Also, there is a theoretical possibility: cell phone hardware itself has a "back door", or the operating system of loopholes. In this way, designers will be able to phone pre-orders, under some kind of danger, by way of some kind of remote control operation; In addition, the operating system's vulnerability may also have virus "release."



    Identification Results: "undercover software" can indeed when the undercover agents and the extent of its formidable than GSM jamming devices. The virus will open the command cell phone call feature. However, the terror-stricken nor necessary. "Undercover software" needs to be installed in order to be implanted into the mobile phone into, but also the main concern is the use of Windows Mobile, Symbian and other OS smartphone. Even smart phones, mobile phones that they do not lend to people with malicious intentions prolonged use, not much in the possibility of strokes.



    In addition, even if the mobile phone users into opening attachments containing the virus, MMS, if the user does not fooled is not installed, the virus is also helpless. Through other means of transmission, such as infrared, Bluetooth, etc., the same can not be "forced" to install mobile phone viruses.



    Very powerful micro-listening devices?



    GSM jamming devices, eavesdropping technology, content and implementation costs are too high, and the "undercover software" needed to get other people's cell phone bugging installation. However, a miniature cell phone listening devices called the product has been on the market, the price is not high, probably 200. It is reported that if the size of a matchbox, built-in lithium battery, with a complete mobile phone features, but also a microphone for radio, but no microphone, so the operation will not be sound. Insert the SIM card as long as the account, you can make use of voice communication networks, the use of comparable to the film scene.



    Sales personnel, such as some people attempt to eavesdrop will be in someone else's office, the family inconspicuous place secretly installed listening devices. Or, you may be presented with a small item, there is no strange appearance, but perhaps the side of a gap, in fact SIM card slot. Inserted into the SIM card, it becomes a mobile phone. Eavesdropper can always dial the station "mobile phone" and turn it around to listen to the voice of your fill. However, the device defect is most obvious power problem, generally only 6 hours of continuous use.



    Identification Results: indeed able to eavesdrop, but the cost is also low, the scourge of much use if they are criminals. However, in addition to electricity, this tiny cell phone listening devices there are weaknesses, it will be a fixed installation, can only be used in a specific place and can not eavesdrop the user all of the talk, but can not see the text, surrounded by noise from the larger goals, or tapping too distant, have no way to hear them. If the user has been eavesdropping on suspected possible, carefully check the home or office, it can probably be found in such tiny cell phone listening devices. Of course, worthy of attention is, sale, purchase use of these products are likely to break the law.



    SIM card copying any bugging devices?



    Probably by the ICAC, as well as the film "eavesdropping situation" and "encourage", "mother card can be copied without SIM card mobile phone tapping anyone's call," the mass SMS has suddenly found a "ride." SMS is not only a way through the mass release of such information, journalists on-line search into a range of selling SIM card copying device fujitsu lifebook t4020 series laptop battery in price from 1,000 yuan to 3,000 yuan in all.



    They said as long as the first billing (often to the designated bank account to play them or transfer), we can provide in accordance with the payer of any cell phone number to copy, copy the card payers get inserted into the phone, you can tap the number calls, SMS. However, not surprisingly, all those who refused the sale of the first test, pay later.



    Identification Results: This is the use of "number changing software," and carried out in outright fraud. When people first hit of the models, then tapping things go down the drain, while the traffickers are mostly dark and quiet without trace. Previously, journalists have reported, GSM mobile phone SIM cards can indeed copied, but the premise is to get the other side of the original mobile phone SIM cards, mobile phone number alone is impossible to copy the SIM card information. And, if replicated, call or text message will only give to a mobile phone, and can not be achieved at the same time answering. Therefore, consumers do not have to care about this eavesdropping fraud.



    News Extension:



    Cell Phones four strokes



    Trick one: I have to pull off the battery



    Shutdown and then unplug the battery is necessary. For example, in "The Lives of Feng Yun", the fear of being tapped boss, to tell the Secretary of commercial confidentiality, the order the Secretary to take off the battery. It is reported that many of the domestic secret meetings, the participants will be asked to remove the phone battery or simply ahead and confiscated the mobile phone another store. Experts say mobile phones are still stand-off in a matter of fact.



    Trick 2: Do not phone to strangers



    To copy the SIM card, to install the "undercover software", has been eavesdropping phones must be left to him. So, if you keep poor cell phone, can be installed on the malefactors have some sort of virus. So, if you think your whole body sensitive, it must be careful of their own mobile phones. Of course, the vast majority of ordinary people do not have to worry about.



    Trick 3: the virus is more flow and power consumption of mobile phones



    Mobile phone data traffic, as well as changes in power, you can roughly determine whether the cell phone bills. This standard is the basic right cell phone virus is very effective. When tapped, the information sent out is to spend energy. So you may find that cell phone off, the power is still very soon. On the other hand, cell phone traffic fees would probably be no reason to surge.



    Tricks 4: Confidential call noise



    Like the movie, like the anti-eavesdropping, if you have a very confidential conversation, but also a high degree of suspicion of eavesdropping, may wish to learn the plot of the film noise. Because listening devices are the same, is also very sensitive to noise. The effect will be very noisy around the eavesdropping greatly affected. However, the mobile phone users need not paranoid, mobile phone tapping is far from apple powerbook g4 17-inch laptop battery.

    Novel ZAP cells using air to produce electricity








    As there is a zinc cathode electron shell, the air deflector into the hole, a chemical reaction of oxygen and zinc, they generate electricity. The structural design efficiency is very high, can achieve three times the power.

        Global consumer electronics products want smaller, lighter, at the same time, manufacturers will want their devices to produce more energy efficient. Energizer ZincAirPrismatic (ZAP) battery is able to meet all these demands a solution.

        The product uses the same with the hearing aid batteries ZincAir technology, by making the zinc and oxygen in the air react to generate electricity. Energizer's Director of OEM Marketing JonEager introduction, positive and negative electrode material determines the nature of the battery, the typical alkaline 5 (AA) batteries used two kinds of zinc and manganese dioxide material, two kinds of materials to be integrated into the cell to should take up a lot of space. However, ZAP battery difference is that it only contains a "zinc" a material, another need is the air of oxygen.

        As there is a zinc cathode electron shell, the air deflector into the hole, a chemical reaction of oxygen and zinc, they generate electricity. The structural design efficiency is very high, can achieve three times the power. Compared with the rechargeable lithium batteries, Energizer batteries for OEM manufacturers ZincAir significant cost savings, while providing the same slim and compact form factor, without charging circuit and charging devices can be used. The product's innovative features include the new 5mm Prism (rectangular) structure, its energy density in all portable consumer power solution second to none. Prism structure has many advantages, first, the design of electronic devices become increasingly thin, OEM manufacturers need the size of the battery itself, we should try to thin. Prism structure can be more efficient use of the volume. In addition the battery through ZAP oxygen in the air play a role, use the prism structure, relatively easy to make the air flow into the battery out; while for ordinary circular batteries, air into the not so easy. Prism structure also allows access to the air contact surface area is relatively large, relatively stable electricity generated.

        Since ZAP batteries need to use the oxygen in the air, so air management system design is essential. JonEager pointed out, ZAP cells need oxygen to and inside the interaction of zinc, so the oxygen capacity and discharge rate must be proportional. Consumers first battery when the battery is first necessary to block the air holes into pieces to remove, and then put to use to use electrical appliances on. However, prolonged exposure to the air so that the battery may cause cell performance slightly affected by some impact. Need to restrict access to the battery in the air, can effectively increase the apple 12 inch powerbook g4 laptop battery life. "In addition, some special circumstances, Energizer company also has a special solution", JonEager explained, such as Tibet and other highland areas, the proportion of oxygen in the air less, may have some impact the battery. So Energizer special areas for the program, allow OEM manufacturers to understand they were going to where the battery used, and Energizer will help customers determine and design in order to obtain the most efficient solution. Of course, under normal circumstances, even in a lot of high mountains, oxygen battery for ZAP is also very adequate.

        "The other extreme environments is a hot and humid conditions", JonEager continued, humidity conditions that can affect the performance of the battery, if the extremely dry, then the batteries may be rendered useless; humidity is too high, then the internal battery will retain some of the air liquid. So Energizer team of engineers to the world's 60 major cities, 365 days a year, by the hour monitoring, collecting data on extreme weather limits and in accordance with the actual data to carry out the battery product design. "After monitoring, we found that most urban conditions are close to the middle of the range, that is relatively rare in the extreme circumstances. Of course, if the customer needs to the harsh desert environment, the use of batteries, Energizer companies do not recommend the use of the battery ZAP program. In short, consumer electronics products in general terms, the general work at room temperature without the need to have very poor conditions, difficult circumstances, there is no big problem. "

    HP's complaint focused on the quality of the outbreak: Notebook temperature can be fried eggs








    Months, the China Quality Miles official website, consumers complaints about HP notebook computers surge. So far, nearly 200 cases of complaints. The same period, activist networks and 315 complaints from consumer electronics to provide the data network, Hewlett-Packard notebook computers have more than 700 cases of complaints from users. HP's consumer self-organized group of activists QQ users has reached as many as 20.

    Able to "fried egg" notebook



    "To be honest, I really wanted to smash it!" September 25 in Beijing, Wang Ming (at his own request, his real name) pointing to 5,000 yuan his units to spend money to buy, using the HP notebook has been two years V3431au , shook his head. The previous 10 days, has been an angry consumers publicly smashed his own HP laptop, and severely stepped on Jijiao - This short video is still widely circulated online.



    Let Wang Ming difficult to accept that his Hewlett-Packard laptop computers in the short span of two years, a total of three times maintenance, and burning of the two motherboards, there is a time was the fan. "My normal work and life have been seriously disturbed ... ..."



    August 5, 2007, Wang Ming, the money spent 5,000 yuan to buy a Hewlett-Packard V3431au. "When I first chose to buy HP laptops, one directed at its brand to go, I feel the quality is also protected, and second, HP's notebook made very beautiful," Wang Ming of the China Quality Miles told reporters. Nevertheless, he did not expect that the use of only six months, it appeared the phenomenon of black. Sent to the HP Care Pack service stations testing, maintenance staff, said the motherboard burned, and needs to be replaced the motherboard. However, six months after the free replacement motherboard, the same problems actually arose. This is how the matter in the end? Wang Ming, very puzzled.



    But the mere touch, Wang Ming can also be aware of laptop overheating - hot. Wang Ming said that he was his own laptop to use, love has always been very careful, because the high temperature machine specially self-made cooling rack. Can notebook still "persistent high fever." When the temperature continues to rise for some time, the computer began to strike - automatic black, working lights all bright, pop-up drive ... ... HP Care Pack service personnel said there may be static, but the King tried off power, remove the Dell INSPIRON 8600 Battery and other methods and found These measures appear to have little real effect. So, in the end, where is there a problem?



    Measured using specialized software over the temperature before he knows that Taiwan has just finished changing the motherboard, clear the dust off the notebook boot in 83 degrees cooler graphics card, 18 minutes later, as high as 100 degrees!



    Similarly, Hewlett-Packard Wuhan attracted consumers purchase high Shu-juan, their experience may even be greater when compared with the Wang Ming. In February 2007, high in the Hongshan District of Wuhan Branch Stars Hewlett-Packard store to spend 8400 yuan bought a HP DV2156TX laptop. "Who got the beloved treasure, really care for me. Whose hands dirty touching my computer would have been my supercilious."



    However, after 3 months of the day, GAO Shu-juan notebook sudden Blue Screen of Death. After the crash, she shut down for a while, re-boot did not find anything unusual. She was also believed to cause a computer crash for many reasons, not surprising. Till February 18, 2008, GAO Shu-juan notebook suddenly appeared, "a long two short" alarm sound (monitor or video card error), and soon a complete breakdown - but she did not think that this is only a flood of trouble a prologue.



    HP Care Pack Maintenance Department are sent after the tested motherboard burned, changing the motherboard. "At that time machine why burn advisory board, the reply was: There are many factors." Shu-Juan Gao said. 8 months later, "machine has broken." Shu-Juan Gao a second sent to the maintenance department. "Annoying is that this fix only after a half months later, machine yet again broken, and even burn the motherboard." Shu-Juan Gao said, "three times a year maintenance, which is definitely quality!"



    And Wang Ming and Shu-Juan Gao was one of many complaints from users of HP's notebook quality of the two. In July 2009 to October, consumer complaints for the HP laptop problems surprisingly large outbreak. China Quality Miles Complaint Center statistics show that in a short period of time less than a month of HP's notebooks have been nearly 200 cases of complaints. Statistics on the network, over the same period: nearly 300 cases. The past six months, 315 complaints against the network, electronic data on up to more than 1,000 cases. Hangzhou, 60 minutes and the TV news programs in broadcast quality coverage of HP's notebook, after 4 days had received nearly a hundred complaints call.



    Not stop there. 315 complaints from consumer electronics, network, Sina science and technology, Netease technology, China's financial network, Hewlett-Packard notebook forum, vista home, the Ben Wang, Tianya other sites or forums posts consumer complaints, complaining posts one after another. In such a short period of time, such a concentration of complaints, is a mere coincidence or is there a causal factors?



    "Card door" shadow



    Until 2008 the British Hill & Knowlton card door broke, the Ming did not realize that they have may be the problem card victims.



    According to media widely reported in July 2008, the world's leading graphics card manufacturer NVIDIA (English Hill & Knowlton) acknowledged that some G84 and G86 series of notebook graphics core, packaging material set was defective, if the core temperature rise and fall more frequently, it could be lead to failure, there multiple images, random characters, vertical and horizontal lines, there is no video signal such as one or more of the phenomenon. Although Hill & Knowlton in Britain, said, "only a small part of the chipset for notebook PCs have been shipped there quality problems", but industry insiders believe that "In the past year and a half years, the world's estimated 18 million units sold to configure NVIDIA G84 and G86 series of notebook graphics cards, they are faced with higher display error probability. " Involved in the affected laptops HP, Dell, Lenovo, Apple, Sony and other notebook manufacturers a variety of models of notebook IBM THINKPAD 390X Battery.



    Almost the same time, NVIDIA statement, will be reserved for a one-time payments, the amount of up to 150 million ~ 200 million U.S. dollars to deal with the accident.



    Soon, Hewlett-Packard's official website announced that the affected models include the Pavilion dv2000/dv6000/dv9000 as well as Compaq Presario V3000/V6000 Series - Wang Ming and high Shujuan notebook are included.



    HP's official website announced Pavilion dv6000/dv9000 and Presario v6000 series graphics cards affected by the issue of fault symptoms include: Can not detect wireless network or equipment; Manager can not detect the wireless network card; LCD screen or external monitor no display; can not boot (need to Frequent start to start); not start; battery charge indicator light does not shine; startup beep prompt appears soon as power is not connected; external display can work, but no built-in LCD screen displays.



    At that time, HP announced that for this series of products to provide a follow-up service planning, if the user purchased this notebook damage is caused by defects in question, it will provide free repair, if not, also want the user to quickly update the BIOS (ie "Basic Input Output System") to prevent.



    This is what was referred to HP's wide range of "limited warranty service enhancement" program.



    Some experts questioned the time: "This solution (in the BIOS where the fan forced open) simply to reduce the rate of change of temperature in order to extend the life of the chip, but 'suffer' over one-year warranty. This approach is not only a temporary solution is not a cure, but also a great impact on the battery endurance, right to buy related products, the user is quite irresponsible attitude. "



    Wang Ming said that although the gold medal back in to HP's repair frequently encountered when the user experience is similar, but because they were all free of charge repair, we also blow off steam, but rather the "is not the case this year," - as "card door" involved in the two series of notebooks from HP in 2006 began a trial in 2007, began selling - and the warranty is only two years, many consumers have faced a notebook now, or have been Paul Paul.



    Once they are over, consumers are faced with a very high price - Wang Ming, said that Beijing Ciyun Si shop to replace the motherboard offer is 4,000 yuan; GAO Shu-juan said, Wuhan, Hewlett-Packard repair gold board is charged 3,000 yuan.



    A senior IT industry analysts, this is the year, consumer complaints, the reasons behind the large area, which essentially revolves around a warranty period, consumers and the game between the interests of multinational SONY VGP-BPS9 Battery.



    Today, by "door card" effects of the number of how many notebooks? HP's public relations department, said one person is still unable to provide accurate statistics.

    Phone tapping staged situation, Yizhenyihuan?








    Cell phones are indispensable to our daily lives, common tools, but it is likely to have become a dangerous tool, which originated from the area of wiretapping technology to the spread of mobile phones. Maybe you are not classified in the core technical staff, maybe you are not worth a lot of money for business leaders, but when you know your private lives are being overheard, you would feel? Maybe you certainly have to ask me how to guard against the cell phone tapped? Phone tapping is a high-tech product, but this makes the product vigilance impact on our lives do?



    Take off the APPLE A1057 Battery, cell phone not leave the body, pay attention to traffic and power, a noisy environment more secure



    ■ carried out in the end of news



    "Today's science and technology, do not have to install listening devices. Now every person has listening devices." Released this year, the Hong Kong film "The Lives of Feng Yun", by Daniel Wu in this case the audience was impressed. He plays a professional listener, in the film shows how to use an ordinary mobile phone wiretapping.



    Daniel Wu will be a mobile phone number input software dialog box, press the Enter key, the corresponding mobile phone becomes a listening device - as long as the cell phone next to the sound, can be reached the listener's headphones - even in the cell phone off later, it is still bugging.



    This is a fictional film, or reality? If there is really possible, how do we prevent?



    - Doubt that a --



    Really "GSM jamming devices" do?



    "Eavesdropping situation", the Daniel Wu mentioned that this type will be able to wiretap mobile phone number system, called the "GSM jamming devices."



    Search on the Internet, found that "eavesdropping situation," began playing, there are a lot of people to sell "GSM jamming devices," three or four hundred yuan a set of bellowing. According to media validation: these things are get money for.



    So, in reality, the existence of such machines? Nokia Siemens Networks believe that the BCS system engineer Zhang Guanghua, GSM mobile phone signal is technically very easy to "intercept" and "decoding."



    Mobile Communication Theory, is one of the voice signal wireless upload it to cell base stations, through the program-controlled switching system transmitted to the other mobile phone. Zhang Guanghua said that in today's cellular mobile communication system, each base station of radio frequencies do not exceed a few hundred. If you want to eavesdrop whose cell phone signal can be at one with the same cell, and then be able to receive the cell base station is responsible for all the signals, and "cracked" it.



    Target all the information issued by the ACER TRAVELMATE 4000 SERIES Battery, including its number, are those where a digital signal. Eavesdropper needs to be done, that is, from a bunch of "1" and "0" find the required information. As long as the use of sufficiently complex equipment, it would not be difficult, especially for the GSM network is concerned. Because domestic GSM network to transmit a digital signal is not encrypted - because the GSM encryption algorithm has long been compromised, nor will the second-generation network operators to design new encryption algorithms, simply is not encrypted.



    Third-generation CDMA networks, and various encryption algorithms, on the security of some, but not the possibility has not been cracked.



    Zhang Guanghua said that, in fact, legitimate eavesdropping public security authorities need only to program-controlled switchboard room operator, by off the shelf equipment can be. Do not need to be achieved by blocking the signal.



    - Question 2 --



    Do not call, the phone can also be tapped?



    "Mobile phone into a bugging device is possible." Motorola's Mobile Devices Division, said Wang Yu, an engineer, as long as some kind of Trojan viruses, cell phones can indeed secretly monitor their environment.



    Now the smart phone is like a computer, software, various functions can be called, regardless of whether the software is well-intentioned, or viruses. If the phone tapping of the Trojan, then the software may secretly wiretap calls some of the features, such as the voice recorded, spread out through the network and so on. Under the command of cell phone hardware and the virus doing these things, the screen or speaker is not going to tell the user.



    Wang Yu, for example, there are some people who attempt to eavesdropping, will send someone installed a Trojan horse of the mobile phone as a gift. Users unknowingly, in relation to the loss of personal privacy or commercial confidentiality. On the other hand, the user's mobile phone if the offender to get hands on the virus may also be installed to achieve the purpose of eavesdropping.



    This got a spy phone, shut down it is. Some of the equipment is shut down cell phone to stop responding, its operating system is still running, the virus is completely able to work.



    - Question 3 --



    Enter the number, you can change mobile phone as a bugging device?



    The movie, Daniel Wu input number and pull out of a wiretapped. This is not to say that: tapping the touch of fingers in the ends of the earth, we can allow any cell phone infected with a virus? Wang Yu believes that this is basically fiction.



    First, the virus infection the way smart phones, mobile phone users are generally mistakenly opened the multimedia message containing the virus attachment, just as computer users by opening the e-mail attachments, like poisoning. If the user does not fooled, and the virus do nothing. Through other means of transmission, such as infrared, Bluetooth, etc., the same can not be "forced" to install mobile phone Dell LATITUDE CPX Battery.



    Second, not all mobile phones are smart phones. For some of the older style mobile phones, it will be impossible long-range "airborne" to a virus.



    Of course, there is a theoretical possibility can not be eliminated - cell phone hardware and a "back door", or the operating system of loopholes. On the one hand, if the designers of the next preset in the mobile phone hardware, some kind of danger, then there may by remote-controlled manner into the virus to (or activate the cell phone comes with a malicious program); the other hand, if the operating system there are loopholes, the virus may also be secretly slipped into the past.



    Having said that, even if all brands of mobile phones, is flawed and the invaders have to first find out what kind of loophole. Like Daniel Wu as "indiscriminate white", enter the phone number will be able to control the possibility of that is zero.



    ■ Expert Tips



    Weapon 1: Shutdown does not serve the purpose, may Qudiao battery



    "Eavesdropping situation", the fear of being tapped boss, to tell the Secretary of commercial confidentiality, the order the Secretary to take off the battery. This is very true. In fact, many of the domestic secret meetings, the participants will be asked to remove the phone battery.



    Once the phone has been bugging the software, even if turned off, but also to avoid the danger that it can not - because of the shutdown, the phone is enter a standby state, it is the exchange of information with the outside world is continuing, the background can still run the software.



    Weapon 2: Do not let phone at random from the body



    While today's cell phone is not like the movie as being a remote infection, but this does not mean that it will not be evil tricks - if you keep poor cell phone, can be ulterior motive were installed on the virus (software or hardware), you blissfully unaware of.



    Similarly, if you have a novel and sensitive, we must caution people to accept gifts of cell phones, maybe this is a Trojan horse.



    Weapon 3: Note that phone traffic and power consumption



    Trojan on the phone when in the dry bad, is not entirely without a trace without a trace. On the one hand, the information sent out is to spend energy. Therefore, the owner may find that cell phone off, the power is still very soon. On the other hand, cell phone traffic may be no reason to fly by. Under these circumstances, the owner should be alert to your mobile phone as soon as possible censorship.



    Weapon 4: In a noisy environment safer



    Like other listening devices, cell phone listening devices is also very sensitive to noise. Once the voice of the surrounding noise up, and its effect is greatly affected by eavesdropping. For example, the environment, there is music, then the cell phone microphone to receive three meters outside the normal voice would be difficult.



    Of course, the safest solution is to simply not to carry mobile phones. Today, a number of private confidential discussions, like the election in the bath, that is, in order to avoid electronic sony vaio t series laptop battery "mischief."

    GSM jamming devices are false, do not be fooled



    By "eavesdropping situation," the east wind, and many online retailers began to sell "GSM jamming devices." "Beijing Evening News" reporter in the Shop saw a "GSM jamming devices", referred to as "the use of GSM phone jamming devices, information technology, tapping someone else. That through the installation of GSM mobile phone jamming devices, so long as to know each other's phone number, issued by eavesdropping program signal, even if the other cell phone turned off, will automatically enforcement procedures, will be launched with a cell phone conversation between those who listen and equipment. " General services cost 500 yuan to 800 yuan, when used according to 0.8 yuan a minute charge.



    "Beijing Evening News," said the so-called "GSM jamming devices," technology does exist, but the actual operation of them by no means as simple. According to reports, the phone tapping within the system structure is complicated, costly, is by no means ordinary people can afford, the general electronic market, there can be no public sale of such products. Therefore, network operators to sell several hundred dollars of so-called "GSM jamming devices" should not be true.



    Undercover software is true, to beware of



    Today, a very popular piece of software is "undercover" software. Whether your phone has a secret, in which undercover agents and the software will always glance. Jiangsu Satellite TV reporter, according to reports, a small company in Nanjing, the presentation will be the software installed on a Nokia smart phone, the whole process less than three minutes. Later, the monitor can be received on the network traffic of this phone and SMS content.



    Not only that, this phone can also be carried out silently listening, just as "eavesdropping situation" where the plot. It is said that this kind of basic business transactions on the Internet, use unknown, but most with the business and emotion.



    In an undercover software, web site marketing, advertising claims that a user "through its help, the success to find a mole inside the company. Thanks to a mobile phone company was only saved by an undercover software, great loss." There are users "through the undercover software, cell phone inside my wife intercepted messages content and call records, confirmed that she had an affair. Also use an undercover software, GPS positioning function in a hotel that they blocked the entrance to the positive, forward."

    The use of listening devices sim cards



    According to Mr. Zhang Guanghua briefing, the reporters noted that the current market sale of a listening device, which plug in sim cards can work, in essence, is a cell phone. It can be made into a variety of shape.



    For example, you may be presented with a white plug wire board, there is no strange shape. How you could not think of it on the side of a gap is actually a sim card slot. Inserted into the sim card, it becomes a mobile phone. Eavesdropper can always dial the Taiwan "plug-line board" mobile phone, listen to the voices around it your toshiba satellite a70 seires laptop battery.



    Different from the traditional listening devices, this mobile phone listening devices is the use of existing communication network to send information, and therefore low cost. Probably four or five hundred yuan will be able to buy one.

    Renewable energy industry: thin-film batteries, hev, nickel-metal hydride batteries, clean-burning








    In late November, we visited in Japan, some of the new energy companies, including Sharp (solar), Toyota (hybrid), Tokuyama (Japan's largest polysilicon plant), Fuji Electric (flexible film and IGBT), Mitsubishi Heavy Industries (Nuclear Power with the clean-burning CCS), the local investment community with Japanese counterparts in an exchange; as a series of reports on the first part, we will simply list the research gave us deep impression on new technologies and new industry directions. Later we will be solar cells, power battery and other technologies to conduct a detailed analysis of the three reports; solar energy, the Japanese enterprises generally focused on the amorphous silicon thin-film batteries and battery, the original, one of five global polysilicon German Mountain chemistry will also be placed on the capacity expansion in Malaysia.

        Japanese companies are basically giving up in the field of conventional crystalline silicon cells to compete with Chinese enterprises in favor of an advantage to do their thin-film battery or a high conversion rate of crystalline silicon cells; Japanese giant Sharp as the representative will be added to the enormous capacity shift the thin-film batteries, plans to expand production in 2012 to 1200MW, its equipment made, claiming that laminated conversion rate of more than 10%; Showa Shell uses its own process of production than the current mainstream of CIS cells less CIGS cells lost CdS buffer layer, to avoid the potential heavy metal cadmium pollution; Fuji Electric is unique in the field of flexible thin-film batteries, the company plans to flexible film forming good an advantage that extends the field of photovoltaic materials; Sanyo Electric Co. Ltd. is taking the high-efficiency crystalline silicon cells the way , from the European market situation, Sanyo battery conversion rates and prices are far ahead of other competitors.

        For EV and HEV dispute, Toyota clear-cut support for HEV; while the nickel-metal hydride batteries and lithium battery choices, they believe the balance of nickel-metal hydride is the best choice (point of view from Toyota); support the hybrid rather than pure The reason is electric vehicle battery technology, cost, range, several aspects of metal consumption, integrated more down, Toyota is currently considered the best choice of hybrid and pure electric vehicles, but the apparent lack of indicators of excellent economy; HP OMNIBOOK XT1000 Battery option is also the case , while lithium is superior to nickel-metal hydride battery technology indicators, but as a tool for short-distance means of transport to use nickel-metal hydride hybrid battery has enough battery was not necessary.

         LED industry is another focus of concern to Japan. The needs of their notebooks and the battery LED will be a demand for the past two years the main driving force, and from 2012, before and after the lighting industry, will bring another wave of rapid growth; clean-burning and nuclear power technology is the focus of communication with Mitsubishi Heavy Industries , in addition to production outside of the Japanese fighter tank rockets, MHI is the world's major participants in the field of power generation equipment; Mitsubishi that its models after many years of safe operation of pressurized water reactor has never been a serious accident, this is the greatest competitive advantage, hand, not too much emphasis on the technical details of the differences between Europe and America; clean combustion and CCS is a Mitsubishi think they have the core competitiveness of the business segments, rather than IGCC (coal) or GTCC (gas) can get a better combination of emission reduction results.

    US-Chinese study of fuel cell achievements of Professor big U.S. Department of Energy Award








    According to the U.S. "World News" reported that automobile research and development technology, with each passing day, all kinds of alternative energy sources such as springing up in order to compress hydrogen-based fuel cell (Fuel Cell), is moving to enhance endurance, high stability and low cost goals. U.S. Head of Department of Environmental Engineering, UC Riverside Chemical Yushan Yan, a breakthrough in fuel cell research achievements, access to the U.S. Federal Department of Energy ARPA-E (Advanced Research Projects Agency-Energy) prize, becoming the nation's 37 was certainly one of the academics.

        ARPA-E Prize winner Steven Chu announced by the Federal Minister of Energy, the nation's application of the more than 3700 research report, Yushan Yan is indeed a rare honor. Yushan Yan from China, Jilin, China University of Science and Technology graduate, after the California Institute of Technology (California Institute of Technology) to obtain a degree, 11 years ago, has taught at UC Riverside.

        Two years ago, he and graduate student from Dalian Shuang Gu into fuel cell research, to significantly reduce development costs for the premise, the use of alkaline environment, nickel, silver and two kinds of cheaper materials, replacing the expensive platinum and DuPont patented high - molecular adhesive Nafion, significantly reducing the cost of manufacturing catalyst, if the next high-volume applications, the automobile industry, the energy industry has brought revolutionary change.

        Assessment in accordance with Yushan Yan, nickel, silver and membrane as long as the original cost of 1/500 to promote fuel-cell vehicles significantly reduce manufacturing costs, so that price of ordinary people. At the same time, the future energy needs do not have to rely on the more dangerous of hydrogen, the change in liquid such as methanol and sony pcga-bp2r laptop battery.

        1839 advent of fuel cell technology, scientific research and development are focused on the acidic environment and platinum, but overlooked from the alkaline environment start with, until the 1960s, DuPont introduced Nifion technology, people believe they have found the answer, did anyone expect that over the past few decades a substantial material cost Rengmei decline in Yushan Yan studies at different angles to obtain significant results.

        The current progress, coupled with more than 90 million federal grant funding, he believed that the earliest years can be applied to the market, the future can even take advantage of solar energy, wind power generation fields.

        New Energy Battery Industry: benefits of new energy vehicle development program

        According to media reports, the National Development and Reform Commission automobile the team leader Wang Shulin, has revealed "new energy vehicle development program" has been submitted to the State Council, is expected to formally promulgated in March 2010. In addition, the state departments will also be launched next year, the development of new energy vehicles for the five supporting measures. Analysts believe that new energy battery industry will be more benefit from the concept of new energy vehicles.

        The new energy vehicles in March next year, introduced the planning or

        While the concept of new energy market, stir-fried, at the policy level came good constantly. Recently held in Nanchang, the new energy vehicles and lithium-ion batteries feature forums, the National Development and Reform Commission automobile team leader Wang Shu-lin said that China will soon release new energy vehicles, technical specification, and the new energy vehicle development plan submitted by the Development and Reform Commission the State Council, was formally promulgated in March next year.

        CITIC Securities (600030) auto industry analyst with Cheng that this concept for some new energy battery companies, such as Shanshangufen (600,884), Jiangsu Guotai (002,091), etc. to benefit more battery manufacturers, but for the entire auto sector in particular, yes SAIC, FAW and other large automobile companies little effect. Energy vehicles would be more car industry and its upstream segment of the cell concept the company have some impact. March release, "the automobile industry restructuring and revitalization plan" submitted in 2011 to form a production capacity of 500,000 short-term goal, which is currently more than 1300 million units for the production of the automobile industry is concerned, a very small proportion of new energy vehicles. For their own smaller battery companies to the past, mainly the supply of mobile phones, computers and other battery-shift production of motive power batteries, 500,000 will be a tremendous volume of business, therefore, the emergence of new energy concepts will greatly enhance the performance of these enterprises .

        As early as March 2009 "issued by the automobile industry restructuring and revitalization of planning" in response to new energy vehicles in the electric car, Development and Reform Commission had been clearly put forward in 2011 to form a production capacity of 500,000 short-term goal. It is understood that electric vehicles, power batteries, electric motors, power electronics, the cost of key components, accounting for the cost of electric vehicle 30% -50%. Based on the calculation 500,000 electric vehicles an annual production value is expected to reach 1,000 billion yuan.

        Previously, the two countries issued a joint statement in Beijing, the two sides agreed in the next five years, Sino-US Joint Research Center of clean energy investment of at least 150 million U.S. dollars, priority research topics will be clean cars. The market believes that the Sino-US Joint Declaration on cooperation in such new energy sources, digital, relatively rare in history, the new energy vehicles are expected to form a substantial positive plate.

        The State Council Development Research Center of Industrial Economics Research Department, Feng Fei energy experts believe that the two sides are expected to take the lead in the field of electric vehicles for cooperation, the Chinese electric vehicle has a huge market and manufacturing cost advantage, but the overall level of the automobile industry, industrial technology, infrastructure was not enough, the United States is precisely in this area has a great advantage, so the two sides take the lead in the field of electric vehicles to launch a new type of automotive products, will become a reality.

        Automotive Li-ion batteries next year doubling of shipments of

         As the environment-friendly vehicles on a global scale are sought after, hybrid and electric cars sells the next few years, automotive lithium battery market will expand rapidly. Fuji Institute of Economic Research reported that after 2010 cars lithium battery market will quickly recover and continue to expand. The report predicts that by 2014, global battery manufacturers than the amount of total shipments in 2008 increased 45.2%, to 6.2392 trillion yen. Among them, rechargeable battery market will be extended to 4.9983 trillion yen, an increase of 66.8%. It is worth mentioning that the needs of the automotive industry will become the main engine battery market expansion is expected in 2009 automotive lithium battery shipments will amount to ¥ 10,400,000,000 in 2008, based on double to ¥ 25,000,000,000; By 2014, the market size will rapidly expand to 2.25 trillion yen, is about 215 times in 2008.

        International management consulting firm Roland Berger Strategy on global prospects for new energy vehicles the latest research report predicts that by 2020 China's electric power drive assembly parts and components market worth 10 billion euros Chao, of which 2011, 2014 and 2017 the market value of 600 million, respectively, 2.4 billion and 56 billion euros, the estimated market value of the middle in 2020 will reach 6.5 billion euros, even a conservative estimate will reach 2.4 billion euros. Based on the forecast the next 10 years, Chinese enterprises in the future hybrid and electric vehicle developments in the field have an advantage, in particular, the core components, including battery developments in the field has great potential because the Chinese enterprises have the raw material cost advantages, manufacturing equipment and labor cost advantage.

        According to Roland Berger predicted that by 2020 will be the major markets in Western Europe, electric vehicles and plug-in hybrids will be more than 3 million annual sales, China ranked second to reach 1.58 million units.

        With the plug-in hybrids, electric cars all the relevant components, the Roland Berger predicts that by 2020, the battery components in the global market share in the largest share of the market size in 9600000000-297 euros between. Now that the Chinese suppliers and Japan, South Korea, North America, Europe, the supplier has a significant cost advantage compared to, so in the future the standard battery in quality, longevity and price differences will become increasingly smaller.

        Roland Berger believes that demand for electric vehicle batteries will be the future of lithium the main source of output growth is expected by 2020 there will be eye-catching 70% of the average annual compound growth rate. Despite the significant growth in demand, but because of higher reserves, experts do not believe that the production of lithium will be a shortage, but there might be a price increase in the risk of a temporary existence.

        Promising varieties of independent innovation of automotive batteries

        Shenyin analyst Wang said that under optimistic about new energy policies to promote investment opportunities in automotive battery industry, promising varieties of independent innovation of automotive batteries. Shenyin that the next 3-5 years, Ni-MH battery HEV will remain the mainstream of new energy vehicles, HEV will PH EV, EV co-existence about 10 years. In the 3-5 years later, with the yield increase lithium iron phosphate batteries to bring the cost down, as well as the national network of charging stations gradual establishment of lithium iron phosphate batteries as the main driving force of the PH EV, EV will usher in a broad prospects for development. Recommended Section Li Yuan (600,478), Shanshangufen, Jiangsu Guotai, Tibet Mining (000,762).

        Shenyin expected future subsidy policy, and the localization rate is likely to hook. In the development strategy, the country's expectation of new energy vehicles as an opportunity to catch up from behind their own technology. I believe Sino-US cooperation, China will continue to insist on independent R & D path. Possible future introduction of new energy car allowance standards, and key spare parts localization rate will be linked to, and encourage the autonomy of key parts as soon as possible and the basis of the localization of raw materials. At the same time the state will improve the access threshold, and rigorous product review system.

        Shenyin expected to follow relevant state ministries and commissions, will be introduced to encourage large-scale electric vehicle applications and the development of specific incentive policies. The industrialization of new energy vehicles, including the most important policy for consumers to buy new energy vehicles are subsidized, and the development of new energy vehicles and infrastructure planning. Introduction of these two policies that will address bottlenecks in consumption and the use of the sony pcga-bp2v laptop battery.

    Mercury-free batteries 8 years behind the interests of the patent is invalid Game








    I believe attention to the cause of the development of China Battery readers still remembers how, early in 2006 in a remarkable message: After careful trial, the Beijing High Court on the new Leader Battery Co., Ltd v. National Patent Reexamination Board to make a final ruling that the case: the trial decision error of fact, the appellant the new Leader's main grounds of appeal set up to support his appeal request to revoke the first-instance ruling and the State Intellectual Property Office of Patent Reexamination Board's decision to maintain the name "mercury-free alkaline New Zealand-shaped batteries" , Patent No. 01,234,722.1 the utility model patent valid. See the news readers sigh of relief, thinking that this means that in China, and the world the battery has an important significance in the history of mercury-free button the dust has settled patent ownership of China's mercury-free Dell LATITUDE D520 Battery development will move toward a virtuous development. However, the surprise is that this began in 2002, the final nail on the controversy over the end of 2005, but it is far from over, in the next four years, still in the endless continuity. 8 years, three lawsuits, two to reverse the verdict, but ultimately did not reach a conclusion, should have the benefit of all inventions, but until now hanging in the air, not only failed to bring to the enterprise in the interests of the imagination, but will be a drag the burden of its development, the desolate Jiaoren Nankeyimeng can not help but distraught. Why is a clear structure and determined that a clear, meaning an important inventions will lead to so many intertwined? What exactly has hidden behind this hidden secret that something? Mercury-free batteries is very important to mankind, because of mercury products, including the threat of mercury batteries inside the health of people around the world. It is reported that a New Zealand-style micro-mercury alkaline batteries can be contaminated water is 600,000 liters, equivalent to the amount of drinking water a person's life. Although in 1995, the United States and Europe have issued a ban on the sale of mercury-containing batteries with the relevant provisions, clearly defined, alkaline zinc-manganese batteries can not be added mercury and mercury content of no more than 0.0005% of total cells, but because the world has no technology can produce mercury-free button batteries, button cells can only allow mercury content of no more than 2% of the total mass of the battery. The export volume of China's battery has been for several years accounted for more than half of the total international battery. Keeping with international standards, in 1997 the Chinese government issued "on the limitation provisions of mercury batteries" and other series of measures. China's battery industry in a short span of two or three years, research on the adoption of technology to solve the mercury-free alkaline zinc-manganese batteries the issue. However, the face of ever-increasing amount of button batteries, the world without a corresponding solution. In other countries, more than a decade in Japan and the United States, Europe and other well-known battery manufacturers of mercury-free button cell mercury-free overtaken by a large number of studies. However, there are technical problems are not resolved, there is no one company can successfully produce mercury-free alkaline button batteries, resulting in the global market has been the use of mercury-containing alkaline button batteries. Button cell 1 billion each year by the production and use, so that China and the rest of the world people are still faced with the danger of mercury exposure. The battery industry finally came good news. Mercury-free button batteries after numerous failures, the new Leader Battery Co., Ltd was finally in 2000, the initial success. October 3, 2002, the new Leader for the "mercury-free alkaline button batteries" utility model patents successfully been authorized. In order to avoid patent issues encountered in overseas markets in the first time, the company again sync in the United States, Germany, Britain and other EU countries have applied for a number of the patent. As a long time in the world coin battery industry has been plagued by excessive mercury content, although many well-known companies before in the field research breakthroughs, but did not succeed. Therefore, the first one to eat crab new Lida was in the hands of the right to speak in this industry. In accordance with the then estimated that if the day of the production budget of only non-Ersanqianwan button cell, then a month's output is 7-10 million. There is also a month's output of more than billion yuan, the new company plans IPO Leader, developed into a million or more large enterprises. Clearly, this is a huge market. At home and abroad, production is not a new coin battery Lida an enterprise, while facing the new Leader of the invention, apart from the envy of some of our competitors, there is also a trace of worry: because the current New Leader has applied for a patent, it also mean that the only new Leader, or the right to possess the technology to master, then in accordance with regulations, and other competitors can only stay away from this piece of a broad market. In order to obtain this piece of the market, individual infringer, drilling the legal loophole, the use of patent reexamination system, make the patent invalid request, would like to eat the inventor of the patent free of charge. New Leader on the market soon found a large number of simulated mercury-free button batteries, and took away a lot of customers. Even stranger things yet to come. On the new Elite has not taken measures to safeguard their own legitimate rights, infringing enterprises blame to the national patent for a new Committee on Lida patent invalid request. Request to annul the new Leader of patents a company in Guangdong. Cylindrical type batteries that since as early as 90 years in China had realized the mercury-free technology, the new Leader of the button cell shape change though, but the principle has not changed is the compaq 204263-001 laptop battery able to think of the field of technical staff in general and to do technology. The new Leader of the patent is obviously not creative. An application declared the patent invalid. In order to give in is the new Leader in 2003, in March, infringing the company's head has engaged the person in charge to meet the new Leader. Stress required to share the patent with the new Leader, otherwise the application for a patent invalid, to become public knowledge technology, which means that any one company can be involved in this market. "Your patent is an antique vase, this is very valuable antiques, you cooperate with me, free me half of the value of the antiques are still, you still have half, but if co-owned with my, I have the ability to play this antique broken, it is not worth a penny. " Each other's unreasonable demands and threats of new Lida was immediately refused, as the new Leader firmly believed that his inventions will be patent law should be protected. However, the result was unexpected. In May 2004, the State Intellectual Property Office, the Patent Reexamination Board with a new patented product Lida button cell structure and has no substantive difference between the structure and its mercury-free alkaline manganese battery technology and cylindrical similar as the basis, so out a declaration of "mercury-free alkaline button-shaped batteries" utility model patent is invalid decision. The outcome, the new Leader's dissatisfied, then to the Beijing Municipal No. 1 Intermediate People's Court proceedings, the Patent Reexamination Board to court. However, the Court of First Instance is still admissible criterion of the Patent Reexamination Board made a decision to maintain the patent invalid. Then again stress patent infringer of people have signed an exclusive patent license contract for free, such as signed by the infringer also have this patent, can guarantee that the patent valid, do not sign the formal null and void. Patentee refused, then hit the Beijing High Court lawsuit. After careful trial, December 20, 2005, the Beijing High Court made final: it removes the first-instance ruling and the State Intellectual Property Office of Patent Reexamination Board's decision to maintain the name "mercury-free alkaline button-shaped batteries", Patent No. bits of the utility model patent for the 123,456,722.1 effective. A dramatic scene appeared, in the High Court of Final Appeal ruling, the infringing party to launch a second invalid undo the action, but the applicant changed to the secretary of the company's CEOs. So in the next three years, the new Leader had to repeat the previous process until August 22, 2008 the Beijing Municipal Higher People's Court again rejected the Patent Reexamination Board, as well as a Beijing Intermediate People's Court's decision. China has an old saying called Shibuguosan. However, it appeared to be very persistent opponent. In 2008, the infringing party has repeatedly brought back to the Patent Reexamination Board invalid. Shocking in June this year, the Patent Reexamination Board to determine the third time the patent is invalid. Lida that the new mercury-free technology is the cell area of general and technical personnel in Japan, the technical basis of unsuccessful easy to think of technology, there is no creativity, now the new Leader has been to the Beijing Municipal Intermediate People's Court proceedings. As a blank to fill in the world, to bring the Gospel to the world of environmental protection, giving Chinese companies opportunities invention, it has experienced eight years of marathon litigation. Year after year, the lawsuit should have not only failed to bring benefits to the inventor, but has become a burden at all times Jiaoren lazy. At the same time, in the endless litigation under the influence of the development of enterprises greatly damage. Due to the adverse effects of litigation, making the market a new image of Lida affected, more than 50% of orders have been infringed away, product prices fell more than 30%, resulting in the profit is very low. The new Leader of the dream do not know when the listing can be achieved. The competitors have a new Leader malicious invalid patents obtained in the course a lot of benefits, the business seems to have done in full swing. In an appearance of legitimacy from the patent is invalid case, we can not help but send questions: Who will protect the rights of the inventor? For this case, some experts believe that market competition is a double-edged sword, bringing vitality to the market at the same time, it also brings risks. Without the constraints of the disorderly competition will not only upset the market, and even the market will bring disaster. And because a number of legal measures, imperfect, leading some people have an opportunity infringement, in order to seek their own selfish desires at the expense of relationships and the use of means of coercion to eat the patentee's patent, really daunting! apple a1045 laptop battery industry believe that the Chinese a leading global, the world's major contribution to environmental protection technology is a patent can not be established to make the reasons for invalidation of the three-day decisions, leading to ownership of independent innovation of enterprises received only eight years, the patent is invalid Dabu Wan lawsuit, infringement, unless the long-term large-scale infringement, even more terrifying is the franchise you want to eat like triad means, so that one would have a bright future development of enterprises, the gradual loss of competitiveness. SIPO Patent Reexamination made by members of the three-day review of the decision null and void, you can act against each other with the Court, but not appropriate departments to monitor, and now there is corruption in society, culture, hope that the Central and the State Council leaders will pay attention to this innovation intellectual property rights have been three-day non-normal conditions is invalid, Save China's own innovative enterprises.

    Virus battery fast charging








    Day trip full to the brim, and are in negotiations with clients dealing a critical moment you suddenly find Shoujimeidian, and so you quickly find the vicinity of power, just 10 seconds of mobile phone battery will be restored to full grid state.

    Even more surprising is that in your electric car batteries, the actually used by the virus produced positive and negative material! But do not be afraid that such cells not only failed to toxic materials, and SONY PCGA-BP2E Battery charging and discharging speed is 100 times more than existing batteries.

    Not only is the mobile phone battery charging speed, as well as notebook computer batteries will not be aging, electric vehicles at the same price with gasoline-powered cars can reach the same power and mileage, so the situation is very likely in a few years to be your day to day grown accustomed to things in life.

    Massachusetts Institute of Technology March 11 and April 2 respectively, published an article on its Web site said they developed the two new batteries, a can be 10 ~ 20 seconds to complete the task of small battery charging, a species is to use the virus to make the battery positive and negative to significantly improve the battery performance, even with the current drive hybrid cars rechargeable battery without much difference, "from the performance point of view, the virus may be in the future replace the battery in the car battery dominance The lead-acid batteries, to seize their market share in automotive batteries. "BYD Company Limited Chief Engineer Liu Weiping April 17 told the" investor newspaper "reporter.

    10 seconds to complete the charging

    Traditional lithium-ion batteries have two electrodes, cathode by the cobalt oxide or lithium iron phosphate composition, negative electrode made of graphite, two electrodes submerged in the electrolyte solution. Charging, the lithium-ion - or positively charged atoms - from the flow of lithium electrode graphite electrodes; discharge, lithium-ion flow the opposite direction.

    At present lithium iron phosphate batteries can store large amounts of electricity, but the rate of release and absorb the power is very slow. Therefore, in order to stabilize the speed electric vehicles on the highway when driving better performance than acceleration, while the battery power is exhausted take hours to complete the charge.

    The problem lies in the lithium-ion, these ions with electrons in the material in the HP OMNIBOOK XE3 SERIES Battery is running slowly, take a very long time to reach the battery terminals, transmission of electric power.

    Builds on a new fast rechargeable batteries have been widely used in conventional cameras, cameras, mobile phones and laptop lithium-ion rechargeable battery. However, its relatively slow charging rate is affecting people's everyday work life, a major obstacle.

    The researchers will be made of lithium iron phosphate structure of the traditional electrode surface to be improved, so that lithium-ion release and inhalation of speed to the original 100-fold. Advantage of this new battery prototype made of only 10-20 seconds to complete the process of charging or discharging. In contrast, a considerable volume of ordinary batteries need charging 6 minutes to complete.

    Responsible for the design of new battery Gebulande? Cedal (Gerbrand Cedar), Dr. said: "The charging and discharging time in seconds rather than hours of battery may be calculated for the new technology opens a door, but also will change people's lives way. "" While in the past two years, which I am not optimistic about a large number of industrial batteries, because the technology is just changing the conductivity of the cathode, while the battery charging speed of the main constraints on the negative. "LIU Wei-ping on the" Investor newspaper, "said," but in the long run, MIT's innovation capacity is very strong and is expected to break out of this in the future, and its industrialization is possible, would enable lithium-ion batteries to further increase market share. "and different from the other battery materials, the new material does not repeat the charge and discharge with aging. Scientists said that the battery can be charged faster to use two consecutive years or 3 years.

    Scientists develop fast charging batteries, said the new technology can be used to develop a new generation of smaller, lighter batteries, mobile phones and laptop batteries heads only the size of a credit card. In addition, this new invention will also nurture a new generation of electric vehicles. Relative to the current charging time takes about 8 hours of battery, the volume of a larger electric vehicle batteries in the future just 5 minutes to complete charge, equivalent to 95-fold increase.

    Batteries with viruses

    Daily life, I am afraid that everyone is talking about the virus to avoid any connection. But if you put the virus and batteries together? If someone tells you that there is a high-performance batteries contain viruses, you will Zuoheganxiang?

    This is not science fiction, but scientists at MIT developed are expected in the future market-oriented "virus" batteries.

    The new "virus" battery is not to say the virus using genetic engineering to produce electricity, but to use them to create better battery positive and negative, resulting in improved battery performance.

    3 years ago, the research team once claimed to have bred a genetically engineered virus, the virus can be coated by coating itself in the cobalt oxide and gold or their own way to the formation of the composition of nano-wire battery anode. However, much more difficult to create cathode, the reason is the cathode electrode must be rapidly and has high conductivity. The real situation is that the majority of production of cathode materials are insulators.

    The researchers used a virus called phage (bacteriophage), which is a common bacteria that can infect humans but harmless virus, and be able to recognize and attach to certain materials (such as this study of carbon nanotubes ) on.

    In order to obtain a high conductivity of the cathode, the researchers adopted a method, the genetically engineered virus-plated iron phosphate coating to the material, and then let the virus, "to grasp the" carbon nanotubes, thus forming a network of high conductive materials.

    Research Group Leader, Institute of Materials scientist Angela - Belcher said that the new genetically engineered virus, batteries and currently on the market for popular art-driven hybrid cars rechargeable batteries not only in energy storage and power performance, there is no difference, but also They can also be used to provide a large number of small portable electrical power.

    In addition, the production of genetically engineered viruses containing the new battery technology economical and environmentally-friendly, the reason is the "virus" Synthesis of the battery temperature is below room temperature or at room temperature, at the same time without the use of harmful organic solvents, and for battery the material is not toxic.

    "This virus, a fast-charge the battery with a battery (the R & D) is the same idea, but it will improve Dell 310-6321 Battery performance." Wei-Ping Liu added. These two studies for the Massachusetts Institute of Technology, he said, "according to the further development of technology, BYD to determine whether or not to introduce or learning."

    Of electricity storage: power battery-powered electric vehicles








    People who frequently travel on the aircraft may have found that starting this year lithium battery backup of electronic products can no longer be checked, but must carry, it is mainly to prevent the lithium battery short-circuit caused the fire. In fact, the lithium battery is not as unsafe as it seems the surface, it may even become the next most important vehicle power hp f4812a laptop battery.

    Power battery to be research

    There are a variety of new energy vehicles by category, but according to the most stringent standards, only a pure electric vehicle is the full sense of the new energy vehicles. At present, the main driving force of new sources of energy vehicles, including nickel-hydrogen batteries, fuel cells and lithium-iron batteries, lithium batteries and the iron has been the industry's recognized as a motive power in the most promising direction of development.

    At present, China can produce power with the lithium iron phosphate battery manufacturers are not many, in addition to the famous BYD, there Tianjin power of God, Vientiane Group, CITIC Guoan, among others. Chinese Academy of Sciences Institute of Physics, Huang Xue-Jie told reporters: "ability to develop a more cost-effective, more reliable electric cars lithium battery is an important prerequisite for large-scale commercial ability, as lithium iron phosphate battery good security. However, iron phosphate Lithium phosphate batteries accounted for 80% of the cost of the battery, this is still not made. "

    It is understood that China's major iron phosphate lithium battery energy density can reach 80Wh/kg, close to the international advanced level. National Development and Reform Commission automobile Expert Group, the China Association of Automobile Manufacturers Executive Vice President and Secretary-General Chang Shu-lin told reporters, "Our power battery development objective is to lower costs by 2020 two-thirds of the energy density more than double . "

    Nanchang FRIEND Technology Co., Ltd. has launched a A-level pure electric cars, charging a mileage of 180 to 220 kilometers per hour about 90 km / hour battery life about 25 thousand kilometers. Nanchang FRIEND Operating Officer weeks LU Qing told reporters: "The price of the car about 18 million, if taking into account national and local subsidies, consumer price actually paid about 60,000 yuan. The biggest piece of the cost of car is the battery, the battery cost is about 6-70000 yuan. "

    Full sail ahead of Electric Vehicles

    Although the lithium iron phosphate batteries are still expensive, and other industrial problems, but the electric car industry has not remained pending, the current domestic enterprises in the electric vehicle power management, motor control, spends much ink on the field.

    Nanchang FRIEND Operating Officer weeks LU Qing told reporters: "Our cars have a self-developed power management and motor control technology, now is certified through the United States, we have car exports to the U.S. cost about 10 yuan / vehicle. "

    In addition, the Nanchang University in Jiangxi Province under the Innovation and Technology Development Co., Ltd. Tai Cheong has been dedicated to electric vehicles, power modules, research and industrialization, the current power management systems, motor control systems, super capacitors and other key technologies to achieve a breakthrough. Public information, Nanchang University and Jiangxi Changhe Automobile Co., Ltd. based on the Changhe Ideal II's new co-developed the model of pure electric vehicles, have complete independent intellectual property rights, has now entered the industrialization stage.

    A staff member of the company told reporters, "Chang major innovation in electric vehicles, power modules, industrialization began in October of this year, now has an auto enterprises in Jiangxi reached a preliminary letter of intent from the major innovation to the businesses Cheong Electric automotive power modules for the production of electric vehicles. "

    However, lithium iron phosphate battery giant BYD Liu, senior director of the right of the right balance between technology and the market has a more sober understanding. He told reporters: "I personally believe that for the electric car, the business model is more important than the battery technology."

    At present, the domestic operating model of pure electric cars is still not clear, a rare charging station outlets, charge the way the industry and replacement Dell XPS M1330 Battery for fast charging mode has its own supporters. Pure electric vehicles operating mode restricting the electric car will probably be a major bottleneck in the development.
