The successful development of new lithium battery

Wednesday, September 30th, 2009
Independent intellectual property rights of a new type of polymer lithium-ion battery has successfully developed, will be in the process of industrial production. This unique battery technology is four years ago, back from the research team overseas, led by Lubo Shi Ji-liquid plastic film lithium-ion battery, after yet another achievement of significant results. Currently, lithium-polymer production lines ion batteries are under construction.

It is understood that the liquid lithium-ion batteries are the most important achievements in recent years, one of high technology research and represents the actual power of chemicals at the most advanced level of development. Because of these batteries have high specific energy and recycling, and the good life of a significant advantage, has been widely used in mobile communications, video cameras, laptops and other electronic equipment, and gradually electric bicycles, electric vehicles and other areas. It is estimated that global demand for lithium-ion battery has reached 1.3 billion euros, and with the continued expansion of applications each year. In the liquid lithium-ion battery, while the successful commercialization of lithium ion polymer battery (PLIB) research has been special attention. As a new generation of lithium-ion battery system, PLIB liquid lithium-ion battery not only has all the technological advantages, but also has a higher energy density and better safety performance. In addition, PLIB is recognized as the most development potential and future applications of the battery market. It is predicted that over the next few years, PLIB replace the liquid lithium-ion battery for about 50% of the market has broad prospects for development, is the largest Japanese manufacturer of the battery, and many other investment Key and R & D Management

In the past, lithium polymer national and international ion battery manufacturers to use more U.S. production of Bell Labs, Bellcore process. However, because this method processes cumbersome, inefficient equipment, high investment costs and higher production gaps, constraints to developing lithium polymer ion battery and industrialization. In recent years, domestic and foreign so-called lithium-polymer battery product ion, but in fact, cells of liquid flexible packaging, there is still a large number of flows within the electrolyte dynamic does not have the characteristics of the polymer electrolyte, there are hidden dangers in safety performance. With lithium-ion batteries in the communications and IT industry, the rapid rise of the use, safety, the battery is more important, requires not only lithium-ion batteries with excellent properties power but also requires a higher performance security.

CITIC Beijing Guoan Mengguli New Materials Technology Research Institute and Beijing University New Energy Materials and Technology Laboratory, several years of research, a large number of laboratory work, based on a number of key documents through technology integrated, the first synthesis of a unique structure of the microporous polymer film composite, and then use a single production process of polymer batteries developed a polymer lithium-ion battery. The battery is very low yield excellent discharge temperature and the cycle of use of performance (over 500 times). Packing flexible liquid with the battery capacity compared to the same type lithium-ion polymer battery cooler and acupuncture, etc. In particular, the safety performance of the test performance of a unique advantage. Important, Lubo Shi and research have developed new polymer lithium-ion battery process of production, also has a small investment in equipment and production process is simple and so on. The results obtained with the rights of independent intellectual property will undoubtedly increase the manufacturing industry in China batteries international competitiveness, promotion of domestic lithium polymer and development of ion battery industry and significantly expand the scope application of lithium-ion battery.

What are the green battery?

Sunday, September 27th, 2009

Green means the battery is in use or under in recent years has research and development of a class of high-performance, non-polluting batteries. Is now widely used nickel metal hydride batteries, lithium-ion batteries and are promoting the use of mercury-free alkaline zinc-manganese primary batteries and rechargeable batteries and the ongoing research and development of plastic lithium or lithium-ion batteries and fuel cells all fall into this one category. In addition, there has been widely applied and the use of solar energy for photoelectric conversion of solar cells (also known as photovoltaic power generation), also be included in this category.

Nickel-metal hydride batteries (ni-mh) and nickel-cadmium batteries (ni-cd) has the same voltage (1.2v), but due to the rare earth alloy or tini alloy hydrogen storage materials as negative electrode active material, replacing the carcinogenic substances cadmium, not only to make this new battery into a green battery, but also the battery specific energy increased by almost 40% to 60-80wh/kg and 210-240wh / l. This battery is the early 90s and gradually realize industrialization and, above all for use in mobile phone batteries. At present, although its dominance on the phone gradually being replaced by lithium-ion batteries, but in Europe and the United States mobile phone applications, its market share is still about 50%.

Lithium-ion battery (li-ion) by the lithium ion can embed and de-embedded carbon as anode and reversible lithium intercalation metal oxides for the positive (licoo2, & linio2 or limn2o4) and organic electrolyte composition of its working voltage is 3.6 v, so a lithium-ion battery is equivalent to three nickel-cadmium or nickel metal hydride batteries. Thus the battery specific energy can exceed 100wh/kg and 280wh / l, again much higher than the nickel metal hydride battery specific energy. In view of the above advantages, a few years from 1993-2000, its production and use of a very high rate.

Alkaline Battery (alkaline) compared with the size of normal batteries have higher capacity and with a large current discharge capability. In recent years, has been applied to mercury-free zinc powder, thereby allowing the cell to become a green battery, and become the mainstream product in the original battery, now is still alkaline zinc-manganese dry battery bp machine to use the most power. At the same time, the world is also concerned about the rechargeable battery of the U.S. company has introduced a rechargeable alkaline manganese batteries, slow growth in product applications. This battery to keep the original battery discharge characteristics, and longer charge to use dozens to hundreds of times (deep charge and discharge cycle life of about 25 times).

Plastic lithium batteries (lip) is a lithium metal as the anode, conductive polymer electrolyte to make a new battery, its energy density has reached 170wh/kg and 350wh / l. Malpractices plastic lithium-ion battery lithium-ion battery is currently in the organic electrolyte stored in a polymer film, or the use of conductive polymers as the electrolyte, so that no free electrolyte in the battery. This battery can achieve the hot aluminum plastic composite film package, with a light weight, the shape can be changed arbitrarily, security and better features.

Fuel cell (fc) is a use of fuel (such as hydrogen or containing fuel) and oxidizer (such as oxygen or air in oxygen) a direct and continuous power generation device, due to avoiding the Carnot cycle limit, this power generation is not only efficient (conversion efficiency of the electrochemical reaction can be as high as 40% or more), and non-polluting gas emissions, and therefore the future of efficient and clean power generation methods. Many domestic and foreign companies are committed to developing appropriate mobile phones, notebook computers pem fuel cell, once put into use, its great value for money.

Sealed lead-acid battery is a lead-acid batteries.

The following new green battery technology and related industries developing rapidly.

1. Hydrogen storage material and nickel-metal hydride battery nickel metal hydride batteries (ni-mh rechargeable battery)

2. Lithium-ion embedded materials and liquid electrolyte lithium-ion batteries

3. Polymer electrolyte lithium batteries or lithium-ion batteries

4. Zinc-air batteries and fuel cells pem

In addition to these things, the rapid growth of China’s telecommunications industry, China’s battery industry is at very high speeds to promote environmentally friendly mercury-free alkaline zinc-manganese of the original pool and rechargeable batteries and sealed lead-acid battery technology development and expand applications.

The solar cell industry

Friday, September 25th, 2009
Photovoltaic cells to solar energy can be divided into two categories: cells of crystalline silicon and thin-film batteries. In which cells of crystalline silicon, including monocrystalline silicon (SC-Si) cells, polycrystalline silicon (mc-Si) two kinds of cells, while thin film cells are essentially non-crystalline silicon (a-Si, using silicon, but the performance of various forms) solar cells, copper indium gallium selenide (CIGS, Cu (INGA) SE2) solar cells, gallium arsenide (GaAs) and cadmium telluride (CdTe) the solar cells. In silicon photovoltaic solar cells is the key markets worldwide, including monocrystalline silicon solar cells, solar cells, polycrystalline silicon, amorphous silicon, solar cells.

  

With crystalline silicon cells currently account for 90% of market share because of its high conversion efficiency (conversion efficiency of mass production up to 16-18%), relatively stable (20 years after the conversion efficiency can still reach the plant by 80%), production technology mature faster expansion, the next 5 to 10 years, solar cell products are still mostly based on crystalline silicon materials.

  

If you use a dynamic point of view, from the coastal areas of business users, the shortage of electricity, photovoltaic electricity production in 3-5 years of economic competitiveness. Of course, the basis of coal in the far north-west and south-west of the base of large hydro, photovoltaic electricity production is still an edge of 3-5 years, its vast market lies in the wall PV curtains, lighting applications photovoltaic business.

  

The PV industry in the years ahead, we expect the growth rate of at least 30% or more, after 2007, production of photovoltaic cells 4100MW computer, the next five years, total production of solar cells should reach about 48000MW.

Optimistic about the prospects of the battery industry, IBM is committed to increasing the efficiency of rechargeable batteries

Friday, September 25th, 2009

In the future, to carry a very important place in the technology, IBM intends to focus on the battery.

  

According to Business Week reported recently, IBM announced that it will take many years of efforts to increase the efficiency of rechargeable batteries 10%. Such a research project that allows electric vehicles to recharge a battery can run 50-100 miles 300-500 miles substantial progress in courses.

  

To achieve this goal, IBM has convened an association, it has created a lithium mixed with oxygen with the products of traditional consumer electronics, electric vehicles powered by lithium-ion batteries different. The new batteries will be able to power electricity grid storage.

  

In addition, IBM also hopes from Asia to the reconquest of the U.S. battery industry by divine right. Despite advances in technology, a starting battery is determined by the United States have begun, but now are Japan and South Korea dominate the field.

  

Analysts said that with IBM in materials science and technology, nanotechnology, chemistry, supercomputers professional competence in this plan on footing the battery very good.

Battery fly out to buy radio batteries must be discreet

Thursday, September 24th, 2009

The radio’s battery suddenly exploded, but fortunately no injuries to humans. Recently, Mr. Shen Linyi members of the public due to purchase Nanfu Battery laptop battery No. 5 explosion to bring the matter reflected in 12315. Yesterday, the staff member’s contact experts, the battery is a fake nanfu battery. Experts advise consumers to buy the battery must be through normal sales channels.

 

       Late last year, Mr. Shen in the urban areas a supermarket and bought four Nanfu battery, into the use of the radio. As early as February 28 this year, Mr. Shen will wake up after listening to a radio, they closed the door to go out to work. At noon home, something unexpected happened, and on the bedside radio suddenly heard “bang” to a sound, followed by a battery from the radio on top of high ground bounce out. According to Mr. Shen observation is that the tail section of the battery explosion, battery positive and negative have been “split”, the battery fluid were all in the flow. Mr. Shen will then be reflected in the matter 12315.

 

       Yesterday, after the staff of industrial and commercial Yinqueshan coordination Nanfu and human rights activists charge the battery after-sales service engineers, who arrived in Linyi Peng, the battery explosion were identified. The inspection found that the cell surface near the cathode at the edge of the N-shaped white bars are very smooth, while the white bars on the edge of authenticity shall be in a regular serrated, the next he found that the negative terminal of the battery no metal sealing cap, and therefore concluded the explosion of the battery is a fake nanfu battery.

 

       Peng engineer, under normal circumstances, the regular battery manufacturers do not risk of explosion. Because these batteries have been the raw materials used in an extremely strict special handling, and safety of explosion-proof equipment is designed. However, if there is short-circuit the battery, is mounted against such improper use of negative situations, or the possibility of explosion, so the battery producers will indicate on the packaging warning to remind consumers of the text. The counterfeit batteries because of rough workmanship, and no effective safety explosion-proof facilities, so easy, “SELF”, and some even not in use on the explosion could easily cause harm to consumers.

 

       Peng engineer a brief introduction of the identification of true and false Nanfu battery basic method. For example, see whether the battery anode, or trademarks on the durability date or production date; trademark printed on the availability of laser anti-counterfeit mark; battery at the bottom of whether the “South-fu” word such as steel. Peng engineer, real fake goods and the most fundamental difference is that the negative terminal of the battery internal components, the vast majority of fakes no metal sealing cap, but see the internal structure of the battery approach applies only to professionals, does not apply to consumers , advised consumers to buy batteries to get to the regular store to buy a small shop at the same time to retain the rights protection for future proof of votes.

Applied Technology clever use of laptop battery(b)

Friday, September 18th, 2009

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 %, which may 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 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 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.

Repair laptop battery

4, repair, method of laptop batteries

(A) cause damage to the battery

Notebook computer battery life is longer, often dissatisfied with battery charge, and even show the battery has been damaged, concrete expression of the resistance is bigger, at charging voltage is increasing relatively quickly at both ends. So easy to charge control circuit has been judged already been filled, the capacity also falls. Since relatively large battery internal resistance, discharge voltage drop big, fast, so the system is easy to mistakenly believe that voltage is not enough electricity shortage. The discovery of relatively short battery life, should take appropriate measures.

(B) The battery refresh program to restore the battery discharge time

Big-brand notebooks have a battery refresh program, we can use it to repair the battery. For example: a IBMThinkpad390/262650-based notebook computers, are fitted with nickel-metal hydride batteries (Ni-Mh) batteries, due to normal charge and discharge properly, leading to the battery discharge time is shorter, leaving less than 5 minutes, if the bring notebook computers to work, then it is very inconvenient, what methods can restore the battery( dell Inspiron 6000 battery,dell Inspiron 630m battery,dell Inspiron 6400 battery,dell Inspiron 640m battery )discharge time?

In response to these circumstances, we can use the IBM has launched a battery refresh program to refresh the battery put it back in discharge time, specifically as follows.

(1) the use of AC power to the notebook computer, first to ftp://fip. pc. ibm. com / pub / pccbbs / mobiles / isbr01ww. exe download software provided by IBM notebook computer batteries TP390/390e/390x refresh program.

(2) Restart the computer, press F8 key to enter boot menu and select safe DOS mode.

(3) to enter the directory where the file you just downloaded, the implementation of the battery refresh program isbr0lww, exe, reading a warning message, by asking you to insert a floppy disk, and then press the Enter key to the implementation of the self-extracting operation.

(4) boot floppy disk with this computer, the screen appears StartingPC-DOS. . . Tips.

(5) Follow the prompts to unplug the AC power, the program will automatically pairs of Ni-Mh battery discharge, discharge is completed, the system will automatically shut down.

(6) As the battery temperature is higher at this time should not immediately start, let the battery cool for a while, the plug in AC power.

(7) to guide the computer with the floppy disk, this Autoexec. bat file will run automatically refresh program, and asks the user whether to proceed. Select yes, press the Enter key.

(8) At this point, refresh program began to refresh the battery, the process quickly, when the return to DOS prompt A:> when that refresh has been completed.

(9) Turn off the computer, and recharge the battery until the green indicator light up.

(10) The above procedure repeated three times to get the best results.

Also, many battery pack lithium battery failure is the failure of a power-saving result of the core, this phenomenon can not be avoided. Because each section of the battery core properties can not be fully consistent with some of the quality of somewhat less long after the beginning of aging and the undermining of the whole (series after) the discharge curve. Interest and ability readers can try to open the battery pack, in the multimeter’s help, you can quickly find the damaged batteries (abnormal voltage). If conditions permit, according to the corresponding parameters of the replacement batteries can be qualified product.

5, notebook battery maintenance

1. When no external power supply situation, if the working conditions at the time being less than PCMCIA card slot, it is recommended to remove the card first to extend battery life.

2. At room temperature (20-30 degrees) for the battery of the most suitable working temperature, the temperature is too high or too low operating environment will reduce the battery life.

3. Can provide a stable power supply in the environment using a laptop computer, remove the battery for extended battery life is affected by incorrect. On the Asus notebooks, when the battery fully charged, the battery charging circuit will automatically shut down, so the phenomenon of overcharging does not occur.

4. Suggested an average of three months to conduct a battery power correction action.

5. To minimize the number of battery

The number of battery charge and discharge is directly related to life on one charge, the battery on a step forward to retirement. Suggest that you try to use an external power supply,

6. Use an external power supply when the battery removed.
