“Using the sun-Driven World,” White Paper stressed that the promotion of photovoltaic technology was restricted materials high cost of silicon. The manufacture of photovoltaic cells with wide applicability, the need to develop low cost, non-toxic, abundant supplies of new photovoltaic materials.

Production capacity increases exponentially

Shanghai Institute of Technical Physics, Chinese Academy of Sciences Dr. Chu Jun-Hao, photovoltaic technology has been developed by Bell Laboratories in the 20th century, the first 50 years, the technology development of solar energy. Over the last 10 years, world production of photovoltaic cells to increase exponentially. According to data supplied by Dr Chu in 1997, Inspiron 1100 battery Inspiron 1150 battery world production capacity of solar cells of about 125.8 million watts in 2007 increased to 3.7334 billion watts. He predicted that the future installation of photovoltaic cells per year will continue to grow rapidly. A conservative estimate by 2012 this figure will reach 13 billion watts.

The production of solar cells primarily in China, mostly for export. Chu Jun-Hao stressed that, although in recent years, productions of photovoltaic cells were significantly increased, but the science and technology scientific research is still hot. Although the material costs of solar grade silicon by the end of 2007 from 350 kilograms per $ 400 until the end of the year 2008 to U.S. $ 100 per kilogram, but photovoltaic cells silicon production is still the most expensive cost accounting of a single solar panel, nearly 60%.

Cost reduction is the strategic direction

Chu Jun-ho, the different types of photovoltaic technologies. F3172A PB995A 338794-001

Technologies of crystalline silicon photovoltaic occupy a significant market share. In the whole world is installed solar panels, about 87% of the composition of crystalline silicon. However, the current cost of photovoltaic technology in crystalline silicon is too expensive, need to continually reduce the first generation of photovoltaic cells - solar cells of crystalline silicon thickness of silicon. Although in recent years, the average thickness of silicon wafers from 300 microns to 350 microns in a 150 or so, but not yet on the market can afford.

In comparison with crystalline silicon cells, the second generation of photovoltaic cells - the lower the efficiency of thin film photovoltaic cells, most of the conversion efficiency of 5% ~ 10%. In addition, the thin-film solar cells is not stable, material resulting from exposure to sunlight and deterioration. However, the material thin film solar cells required less raw material than crystalline silicon cells, and not so expensive. Chu Jun-Hao predicted that by 2012 photovoltaics in crystalline silicon from the current proportion of 87% fell to 75%, while the remaining 25% will be based on the movie account.

Chu Jun-Hao also mentioned the new concept of the third generation of solar cell technology - dye sensitized solar cells (DSSC). DSSC with the dye molecules absorb incident light, cheaper than crystalline silicon cells, but the yield is lower than the first two, but there are also stability problems. Dr. Meng Qingbo Chinese Academy of Sciences said that a big advantage DSSC is easier to produce. In China, the researchers observed the materials used in the electrolyte DSSC iodide, lithium iodide classic may be cheaper to replace the aluminum to further reduce costs.

Does the Earth can provide sufficient material to meet the nutritional needs of large-scale solar to attend the first session of the seminar CS3 University of Bath Laurie Bideboshi that chemists need to review past work, using a more appropriate measure on long-term, large-scale application of new materials to perform an alternative test. Inspiron E1705 battery Latitude D410 battery

The future of PV can be expected

Chu Jun-Hao believes that the development of solar cell technology must follow four steps: first, improve the processing technology of silicon solar cells crystalline, which greatly reduce the cost of silicon, improving processing materials and manufacturing process of batteries, so that beyond the addition of 40 per cent of the cost of silicon has also been declining, the second is to develop technology for thin film photovoltaic’s for new ideas and new materials, thus reducing costs while improving performance; 3 is constantly evolving and the dye-sensitized thin-film photovoltaics, the new structure, processes and concepts to improve the cost performance of the product, four scientists in all areas together, working together to find a breakthrough. Latitude D600 battery Latitude D610 battery

On the transmission of electricity on a large scale is concerned, Chu Jun-Hao raises a question: to explore and develop a variety of photovoltaic technology, one of the most effective? According to his analysis of the effectiveness in terms of silicon is still the best material, the next 10 years, the cost of silicon cells should be more readily accepted because they are used less silicon. He also predicted that the molecules of organic solar cells will occupy an important position because of low cost, but before being applied in the realization of large-scale, efficiency and stability of the need to improve.

Waste batteries caused a big discussion between users

Recently, Quzhou San Qu forum on battery recycling waste problem the Internet is widespread concern, triggered the debate.

This discussion is determined by the user Chu published in the Forum Trash “can not create a small pocket on the bag” post triggered. Chu month in your message to reflect a short battery, it will fall into a dilemma, if the batteries and garbage dumped in a garbage landfill cells mixed with waste will create environmental pollution if you do not throw, pile at home for an extended period will be scared, but also pollution, sooner or later, has yet to throw. A1021 M7332 402018-001

Given this situation, Chu suggested that the departments concerned in the trash on the side to create a small pocket or the trash bags to raise the edge of a bucket, designed to save the batteries, the best illustration marked, that people know that this is laying the batteries, so that staff not only to facilitate waste separation and recycling, but also to protect the environment.

Chu months recommendations have been approved by the Internet, the user responses www1818 road: “It is a very good idea, whenever I get the battery ran out of their bottles and a bag thrown in the recycling bins that can not go.”

User www1818 ways to dispose of used batteries, Chu said last month that he had often denied collection staff will refuse simply swept into the garbage truck does not see the staff clearing the waste classification garbage. ThinkPad T60 battery ThinkPad R32 battery

The freewalk users tell us that he had large RT-Mart supermarket in urban areas and the street in motion the business offices of the company saw the collection box of batteries, the batteries must be collected thrown into a special box to collect batteries.

Environmental Protection Agency: a one-time collection and disposal of batteries is not recommended

Where the throw is used batteries at the end? How to deal with really green? The problem with the Internet yesterday questioned the Office of the municipal environmental protection of the parties concerned.

“Currently, the batteries sold on the domestic market have reached low mercury or mercury-free, pollution is very small, so we do not advocate the general focus on the collection of used batteries. Municipal Environmental Protection Bureau staff explained that in the past that spot batteries must be recycled, yes because it was important toxic heavy metals such as mercury. With improved production technology of Chinese battery, domestic sales current mercury free alkaline batteries have reached the level. Therefore, from the standpoint of environmental protection, waste of disposable batteries with the decentralization of garbage per day and does not constitute a danger to the environment. “Focusing on recovery, if used correctly, but may cause localized mercury pollution.” Sony VGP-BPS2B Sony VGP-BPS2C

Staff said the National Development and Reform Commission has published a few years ago, the batteries Pollution Prevention and Control Technology Policy, “clearly that the public commonly used 5, 7, no recycling of disposable batteries, but batteries rechargeable and button batteries and other forms of pollution - heavy, we must focus on recovery from manufacturers, the public can not easily throw away.

The current emphasis on the recovery of nickel-cadmium, batteries nickel hydrogen, lithium-ion batteries, including mobile phone batteries, rechargeable batteries, and batteries for electric vehicles (tanks) and so on. Municipal Personnel Bureau of Environmental Protection, and now the recovery of these cells is still a problem if people are kind of batteries can be linked to the recycling plant.

Municipal Environmental Protection Bureau staff recommends the public to buy time to see if dry “mercury free” logo. If she is usually 5, No. 1, the VGP-BPS2A VGP-BPS2B battery is discharged members of the public and garbage directly together.

Department of Sanitation: the waste of disposable batteries with the life of many landfills

Submitted by users for Chu on the shelf in a small pocket on the trash bag used battery collection and treatment practices and recommendations for the classification of waste, urban construction Bureau Sanitation Department staff has expressed satisfaction for registered users.

With improving living standards, used batteries, electronic waste has increased recently. They comply with national regulations, the waste of disposable batteries with the landfill waste per day. As for waste rechargeable batteries, electronic waste, so that the staff admitted that part of the garbage there after the deal with difficult issues. Latitude D500 battery Latitude D505 battery

“This year we have begun preliminary work to garbage, the staff said that the current two-thirds of urban areas are classified trash, formed by two barrels, one for recyclable waste, a non-recovery load of rubbish. Trash from the landfill waste and wastewater treatment is very good.

“Classification of garbage, we have always wanted to do something, will be based on the provincial and the actual situation of Quzhou City in a planned, step by step to make the work of separation of waste.” Staff members said in the future, once the batteries the public can not be put into the recycling bin, and the disposal of solid waste landfill.

Nevertheless, the torch is still a long experience of high-tech nickel-metal hydride battery R & D and production. It is understood that the torch high rechargeable Ni-MH battery research for nearly 20 years. Since 2000, companies focused on developing nickel-hydrogen, in 2006 developed the “use of hybrid cars Research on nickel-hydrogen battery and development” projects as key components of electric vehicles.

And from 2006, the company receiving country 3 years and 9 million of research funding grants, began to take on development of battery power and research. Torch Hi-Tech is currently the main production of toys and electric power tools with nickel-metal hydride. Torch High-tech 2008 revenue of 13.87 million yuan, up flat; operating loss of 4.63 million, an increase of 1.25 million deficit in the Currently the company has an annual production of 20 million Ah capacity nickel-hydrogen PA3399U-2BAS PA3399U-1BRS battery.

The torch has now become the research with high energy battery and development area, the company has developed very rapidly, is the design, research and Battery Power Development 150000 km. March 3, the torch high-tech securities on behalf of Guo Yi Hang on “newspaper investors, said that currently the new energy vehicles in the nickel-metal hydride, but also some of the products laboratory, no large-scale production, it has not contributed significantly to the company performance.

However, the High-tech Torch still plans to invest in the expansion of nickel-metal hydride, for investment in strengthening the annual production of 363 million plans Ah nickel-hydrogen battery Expansion Project the proposed total investment of 1.315 billion yuan.

According to the announcement shows that the project into two phases by the end of 2009 with an investment of 338 million is expected to start production by the end of 2010, adding 80 million Ah capacity The total production capacity reached 100 million Ah, two years of construction in 2011, the new 617 million yuan, the new 263 million Ah, the total production capacity amounts to 363 million Ah, to 50 million vehicles to use. Function of the rapid development of new energy vehicles in Japan’s investment in related businesses, the majority of investment and focus on areas of lithium Latitude D510 battery Latitude D520 battery batteries.

According to economic forecasts Fuji Japan, the current nickel-metal hydride will continue until 2011, starting in 2011, lithium batteries will start to gradually replace the nickel-metal hydride.

The data show that the estimated agency nickel-hydrogen car in 2009, the cell size of the global scale compared to 2008 increased by 23.7% to ¥ 92,000,000,000, but the car battery nickel-hydrogen in 2015, the market size will increase to 55 billion Japanese yen, nearly half of the decline.

According to the current vehicle of China a dynamic development trend, the torch high-tech nickel-metal hydride while the adoption of six national certification automakers, but has received no orders, it is was in the performance reports did not see red the main reason. 361742-001 371785-001

Meanwhile in the latest global technology road vehicle battery and the lithium-ion batteries to accelerate the industrialization process in the case, the torch high technology development program can be achieved? Although the implementation of the program, investment recovery more difficult than before the increased number of higher risk factors.

But at the same time, the High-tech Torch some of their own development opportunities.

December 10 last year, the meeting of the Executive Council of State said that in five cities on the private purchase of energy saving and new energy vehicles to provide grants for the pilot. Everbright Securities based projections, in 2010 the first batch of 50,000 pilot-scale subsidies on the new energy vehicles in 2011 should begin 15 to 20 cities, power generation new car will reach 200,000 or more. Sony VGP-BPS8 Sony VGP-BPS8A

Consequently, EMC stock judging, the car battery Ni-MH will account for more than 80% market share in the torch of high tech nickel-metal hydrides as large companies are expected by 2010 to 2011 deliveries of nickel-metal hydride, will reach 8500 units and 40,000 units. Can withstand the test to determine if this? Need time to prove it.

February 9, Shanshangufen issued a public notice in order to further promote, lithium materials company developing ion battery industry, and increase industrial competitiveness base and Toda Kogyo Co., Ltd. (hereinafter Toda below), Itochu Corporation (hereinafter referred to as Itochu) materials in lithium battery cathode signed cooperation “on capital and business cooperation memorandum of the transaction.” Owned subsidiary, Hunan Shanshan New Material Co., Ltd.

Statistics show that South Korea, China, Japan and the production of Li-ion batteries in three countries in the global share market up 95%, and competition is very fierce among the three countries. While China’s production of lithium batteries has the third largest in the world, but the product quality and technical level with the other two countries have some distance, and lithium batteries for automotive manufacturers have not cooked yet.

The Toda engaged in the production of cathode material, and the use of mobile phones is the battery of the automobile, and other large-scale developments in the field of battery materials is a dynamic force technology business classification. According to statistics, Toda cathode material about 6% of world market share. Shanshangufen signed with the Toda, he is optimistic about the resources in this regard. PA3383U-1BRS PA3395U-1BRS

According to statistics, the lithium-ion batteries can be used, including mobile phones and laptops, and the Environmental Protection Model (hybrid electric vehicles, electric vehicles, buses, etc.) and so on. Batteries Currently, 70% of the lithium-ion batteries used in mobile phones and laptops, according to forecasts, with the popularity of hybrids and electric vehicles, the new world energy market car should grow rapidly in the world are likely to be associated with this question of their future car development of the industry key battle. apple PowerBook G4 12 inch battery apple MacBook 13 inch battery

The status quo of mobile phone battery in China

As mobile phones become more powerful, the requirements of the capacity utilization of the battery are increasingly high. In recent years, the industry began widespread use of Bigger, Longer lithium-ion batteries. But until now, state authorities have not promulgated lithium-ion batteries for national testing standards.

It is reported that Chinese demand for mobile phones and batteries were more than 300 million euros, the sub-market battery is compatible with original batteries and battery of two. With original batteries are most often on their own manufacturing, quality is relatively good, but the high price. Currently the market is compatible with a growing percentage of the battery, compatible battery prices generally higher than the same size of the original battery is low but the quality is mixed. Inspiron E1405 battery XPS M140 battery

The industry calls the new standard

“Around 2000, the capacity of mobile phone battery is very low, low energy density, 150 ℃ temperature normal, there is no problem. However, with the constant development of multi-function mobile phones and user demand for the startup time, the ability of mobile phone battery larger and larger, high-capacity battery can not withstand 150 ℃ standards, in particular, more than 1000 milliamps of battery capacity can be 130 ℃ test, then what is the use of 150 ℃ or 130 ℃ that standards of heat shock temperature has been controversial for many years. “The person explains:” Until now, the authorities’ state has not promulgated lithium-ion batteries for national testing standards. KD476 TD347 C1295

In 2003, the Ministry of Information Industry promulgated YD1268-2003 “mobile phones and lithium batteries and charger safety requirements and test methods”, in which temperature standard impact test heat have been changed to 130 ℃, become the mobile phone industry, to test the general industry standards, in September 2005 by the State Administration of Quality Supervision, Inspection and Quarantine and the ‘National Standardization Technical Committee alkaline batteries under the auspices of the national meeting standard review, the new proposed national standard, “revised edition”, in which the temperature standards for thermal shock test in A 130 ℃, but for various reasons, is expected in September 2005 enacted a new national standard has not yet issued. Currently, both the manufacturer of the battery or the mobile phone manufacturers in general would be 130 ℃ as a temperature the lithium-ion battery testing standards for thermal shock, and the battery design, production, quality control, procurement and other areas commonly used by this standard. Inspiron 1520 battery Inspiron 1521 battery

According to industry experts, the State is currently testing the use of thermal shock test is to put the battery in the box with hot (5 ℃ ± 2 ℃) / min rate up to 150 ℃ ± 2 ℃ and heat for 30 minutes, the battery does not catch fire or leak, which is a simulation of destructive tests in extreme conditions. In fact, consumers may find difficult to meet in the use of mobile phones such as the use of the environment, even the 130 ℃, was also well beyond the daily use of mobile phones for consumers when the temperature limit. Substituting Nokia, Motorola, Amoi, Lenovo Mobile brand to represent the mainstream of the original battery, all with very catchy captions to remind consumers not to the battery in fire or heat to avoid explosion. GK479 FK890

Development of the industry trend, the mobile phone battery need a new standard. Now, only a small number of Nokia and other mobile phone companies use a unified standard battery. At present, China has gradually become the world’s lithium-ion battery manufacturing facility. Release of the lithium-ion batteries in 2005 to about 35% of the world, with exports amounting to 2.32 billion dollars, has become the second largest production of lithium-ion batteries and the exporting country.

It was also revealed that currently outside temperature standards for thermal shock test, the 2000 version of mobile phone batteries in the specification old national standard for several other standards are multiple industry, partisan wrangling. After 7 years, when the new version of national testing standards at the end, when he introduced, drew the attention of the industry. Inspiron 5100 battery Inspiron 5150 battery

Organic thin solar cell is a kind of semiconductor materials through organic pn junction or PIN junction composition, and then converted into light output of solar cells. Characterized by thin, lightweight, flexible, color, freedom of choice and higher volumes can be produced by volume, it should significantly reduce manufacturing costs. However, there are many different topics. Conac reached an organic solar cell thin film based products, but the module conversion efficiency is only “3% ~ 4″ (CONAC executive chairman and founder Howard R. Berke), lower than the existing number of solar cell. In addition, there are topics such as life expectancy is shorter. Inspiron 5150 battery Inspiron 700m battery

The common development “to achieve an efficiency of 10% module conversion and 10 years of existence as the target” name (Konica Minolta President Executive Matsuzaki is to years). The two companies plan is to know if we could achieve by the year 2012 target, will establish a joint venture, before and after mass production in 2013, to expand sales in Asia as the center. Matsuzaki said “(manufacturing plan since the beginning) 5 years for the 500 billion yen in the scale.”

Konica Minolta has been with General Electric U. S. development of lighting products organic EL launched cooperation). The desire to develop an organic thin film solar cells because “(thin film organic solar cells) and organic EL lighting products is expected to create synergy” (Matsuzaki). Make specific reference to basic technology from Konica Minolta ( 1) Water and oxygen have a high barrier thin-film technology, (2) in a variety of business accumulating optical “light management” (Matsuzaki), (3) in photo film industry, the combined volume of technical roll coating, and (4) a variety of organic materials, technology development, cells of lighting products and organic EL thin film organic solar are two aspects of advantage. Vostro 1720 battery Vostro 2510 battery

On the other hand, is very concerned about the type of non-silicon solar cell is composed of CdTe solar cells and CIGS type classes (see site report). However, the Konica Minolta view Matsuzaki, the use of such compounds, materials, solar cells is of short duration. Matsuzaki also stressed that “There was a time composites have been used as a copier and sensible body. However, toxicity and performance issues such as the existence of problems of instability of amorphous silicon and possibly organic photoconductor (OPC) market. It is estimated that the field of solar cells will also appear in the same situation. ”

During the year 2010 to reach 10% efficiency of conversion of cells is the touchstone of

The two companies established in 2012 in the year preceding the performance target on the issue of life takes shape. Conac Berke said, “is only used in the package with Konica Minolta high barrier film is a measure, it will be for an initial term of five years of outdoor life up to 10 years.” Sony VGP-BPS8 Sony VGP-BPS8A

In addition, the objectives of efficiency of conversion there is a major obstacle. Currently, many companies and research institutions are actively engaged in the development of organic thin film cells, solar conversion efficiency also continued to improve. In the products already announced, the United States of Solarmer efficient energy conversion of 7.9% in units ranked first, and other companies have already reached more than 7%. In addition, the majority of these companies think we can achieve in 2010 years, 10% conversion efficiency of cells.

Conac is also one of them. Conac Berke said, “Research institutions received 7% conversion efficiency of cells. At the end of 2010 will be able to reach 9 ~ 10% conversion efficiency of cells and 5% conversion efficiency module. “A1078 A1045

China’s Path to low carbon content to examine a low-carbon economic development at this stage to consider the cost of priority, on the market to understand the development of the economy with low emissions of carbon, the energy industry new car because of its relatively large market that can drive the development upstream and downstream industry and stimulate consumption, but also save energy economy in the path of low carbon emissions in a privileged position.

2, the new energy vehicles will become a national strategy, national efforts to support exceed other low carbon industries.

In 2010, Mars, the National Development and Reform Commission will be promulgated, the “new energy development program the vehicles,” new energy vehicles will be brought to the national strategy, it will be a major asset for the development of new energy. In all low carbon sectors, the importance of new energy vehicles in the top row, the intensity should exceed state support for solar energy, wind power and other industries.

3.2011 years for new energy vehicles up to 50 million units, driving demand growth of over 50% of cells, with the penetration of lithium batteries improve in the next three can maintain 50% annual growth.

A huge quantity of car batteries, electric vehicle 4000 laptops, each car on average 50 kg of cathode materials, anode materials, 40 kg, 40 kg of electrolyte. If the use of vehicles by 20% for lithium (10 million cars) could also contribute 5,000 tons of positive, negative, 4,000 tons, 4,000 tons of electrolytes. 2009 The domestic demand of 8,000 tons of the electrolyte, increasing only 50% of the demand for automobiles. With the penetration of lithium batteries will increase, more vehicles to use lithium batteries, the next three years, lithium batteries can maintain 50% growth.

4, the development of new energy vehicles, battery manufacturers have the largest vehicle manufacturer has been less affected. Studio 1737 battery Vostro 1200 battery

2009 domestic car production and sales of 13 million 500 thousand new energy vehicles have little impact on the vehicle. Due to rising prices of new energy vehicles, vehicles with lower margin, profit, especially in the upper part of the battery, control electronics and links generator.

5, lithium increased the gross margin, with the actual results support the concept of a new energy even more desirable.

Texas, a group of researchers recently discovered that piezoelectric materials in the form of 21 nanometers (a human hair is 100,000 nm) may be the capacity of energy production has increased 100%, will be available to low consumption of energy of mobile devices and sensors, sound Kaopu not really, but the theory is possible, or hope they succeed. 

Cajun working on nanotechnology, through the use of materials known as piezo-electric, it has developed a self-powered device, which does not require batteries that can replace the food category. In particular, card payments and a partner of the University of Houston have discovered a piezoelectric material in less than 21 nm thickness less than the size of the microwave energy can be converted to 100%. In addition, when this material larger than the specific size or more hours, their rate of energy conversion has decreased significantly. Its findings will be published in the fall of the American Institute of Physics journal “Physical Review B”. This discovery will help develop products at low power electronics are heavy with meaning, it can be developed from I-powered mobile phones, laptops, personal communication devices, computers and many other related products electronics. Satellite M55 battery Tecra A3 battery

Many high-tech components are nano-level. Although the invention Cajun small but significant influence. He concluded that enable small and easy to extend the lifetime of wireless products. Because, MP3 and mobile phone, autonomy is a major problem if you want to expand their capacity, then they need a more powerful battery to support. And a free-running device to resolve this problem, which is several federal agencies interested in the reasons for these devices. In fact, the U. S. Defense Advanced Research Projects Agency (DARPA) has reviewed the field, soldiers how to use their conversation to get the energy to run their portable devices. In addition, the sensors used to detect explosives, would benefit greatly from technology self-powered, can reduce the pain of testing and battery replacement. Tecra A4 battery Tecra A5 battery

Cajun explained that the key to this technology is the piezo-electric body. Is a class of piezoelectric crystals are very interesting, when you push or pull it, it will produce different ends of the charge. This effect is called piezoelectric effect. Piezoelectric effect can produce a crystal is called piezoelectric crystals. Crystal (α-quartz) is a piezo-electric crystal well known. Piezoelectric body is not new, in fact, from 80 years in the 19th century was French scientists have found. At first used in piezoelectric sonar equipment during the First World War. Now, with a piece of piezoelectric crystal of the camera so that the search for technical staff of the steam engine, internal combustion engines and all kinds of chemical equipment in pressure changes become a reality. The use of piezoelectric crystals can be measured or even the pressure of fluids in pipes, guns, firing shells into the barrel when the pressure of the bomb exploded when the instantaneous pressure. In addition, the piezoelectric crystal is also widely used in the microphone array and the quartz. Even the touch of your car also has the piezoelectric crystal. Click the button causes the ignition of piezoelectric crystals generate impact, thereby generating sufficient voltage to produce sparks and ignite fuel. Tecra A6 battery Tecra A7 battery

Of the major applications, a number of European dance floors of nightclubs and dance halls were built by the piezoelectric crystal can absorb and convert energy to generate traces of electricity as a means of light bulbs inside the nightclub. According to reports, the Hong Kong Coliseum is an athlete who uses this technology to convert energy into electrical energy as a means of lighting and playing music. Cajun said that the application of piezoelectric crystal will be a higher level, especially when the emergence of nano-scale piezoelectric crystal, after the application of this technology becomes more widespread.

While other companies’ high-end cell designed to provide fast charge and full acceleration of the battery power, Amperex companies try to improve the energy density of battery power to extend that deadline. More batteries energy storage, which supply power to the car or the phone longer. As carmakers turned to electric cars, but like the iPhone, mobile devices such as energy run more intensive applications, if the energy density of the battery and energy consumption resulting a single load can provide the time, they become a more pressing issue.

Lithium-ion battery Lithium-ion on the anode from the cathode to move, while the flow of electrons through an external circuit, reversing the discharge process. As anode material, compared to the currently used graphite, silicon May accept more lithium, which increases the potential. Indeed, the theoretical maximum density of energy of silicon is ten times that of graphite. Burst however, silicon is brittle and easy expansion, although it took a charge cycle.

However, the silicon nanowires can be prepared in the cycle of the battery anode repeated continuously without damage. Fall 2009, the founders Amperex, Stanford University Assistant Professor of Materials Science and Engineering, CUI Yi (Yi Cui), showed the structure of nanoparticles of silicon-silicon anodic capacity of storage of the way to achieve the value theoretical and have not broken. Long, thin, soft and easy to bend nanowires pad, which makes when the battery charge and discharge to be soft. The nanowire assembly to form a large surface, which means that the site of interaction with lithium and more. FRU 92P1141 40Y6799

Amperex enterprise business development manager at Ryan • If Kedeng Tet (Ryan Kottenstette), said the company has significantly improved the growth of nanowires processes to correspond with the high volume production. Line Nm from a catalyst-coated metal substrate gasification. Anode production company did not disclose details, but said that the production process using a matrix more conductive metal catalysts and less expensive. Yi Cui said: “The anode material may be in sheet metal at low cost on a large scale to produce high speed.

Currently, the Amperex works with vehicles, communications and electronics manufacturers to phase to prepare, in March raised its first round of venture capital funds venture. The company hopes that next summer to raise funds more difficult to establish a pilot production line. KD476 TD347

No matter how excellent the anode, the capacity of the battery all also needs to rely on the cathode. The performance of lithium ion cathode today is not as developed by the anode rod Amperex’s so. Design first cell of society, through the anode thin and thick corresponding to the cathode means to compensate this lack of proportion. With the same size compared to conventional lithium-ion batteries, design Amperex Company may be stored above 40% capacity load. However, to further improve the energy density, Amperex companies will need to search for new cathode material. F4809A F4812A

For laptops, the battery can be considered a more important component, its performance is directly related to the environment of the laptop in the absence of power in the ability to work. The notebook batteries can be considered a public component in another letter of consumables, it involves keeping the laptop battery and reasonable use of this forum is often discussed question. Regarding the laptop batteries at the time set aside to save much more than what should stay and whether the use of power when you remove the battery problems are not always what a unified response.

Generally, the lithium batteries in a life cycle can be 300 to 500 times more charge-discharge. So many people think, so using less energy, while it may to some extent, played a role in prolonging the life of the battery. But they ignore the original battery that the physical nature of the end, when the battery assembly line, that’s life internal clock will then start walking. So even if you do not set aside the battery life of lithium was only two to three years, one can arrive at an end. Battery capacity due to reasons of this decline was due to oxidation caused by the battery internal resistance increases. When the resistance of the electrolytic cell reaches a certain point, but this time the battery still be full of electricity, but the battery has not been able to release the stored electricity.

Overall, in order not to make your premature loss of the role of the PC764 Y9943 battery, then the use of normal, you should try to comply with the following principles:

A. avoid a complete discharge, and often for lithium batteries. Repeated damage arbitrarily rechargeable lithium battery is very low, almost negligible.

B. will need to continue to hold lithium batteries placed in the shade, remember not to refrigerate. Avoid placing hot car, as a time to save the battery to 40% in place.

C. Most of the time if you use a power supply fixed, please remove the batteries placed in the shade.

D. no needs to buy batteries lithium spare storage, so this piece is actually a waste of battery.

The cells are induced to use, so that attention to the rational use and conservation methods, it is not necessary to deal with their excess, which makes it possible for us to “contribution” is the more important. Similarly mobile phones! hp Pavilion dv4 battery  hp Pavilion dv6 battery
