laptop battery to maintain its methods to extend the service life

Do not on the battery in the computer clean boot the computer. For the first time in the use of laptop computers, battery-activated for Operation

In the process of charging the battery, do not unplug an external power supply.

The use of battery time, as far as possible will be used up before all the electricity charge and a charge of electricity will be full, not half way on the charge or discharge. This will keep your battery at its best.

If you do not use a computer for a long time (more than 2 weeks), please take out the battery.

For the storage battery out, you easily stay away from the conductive material (such as water or metal) so as not to lead to short-circuit the battery can not be used.

Separate battery storage time should not exceed the maximum recommended a month, and to ensure that every month or so on batteries recharged.

A separate storage battery, please ensure that the battery power is greater than 80%.

It is recommended that you put the battery temperature range -10 - 35 degrees Celsius in dried storage environments, avoid sunlight.

Laptop batteries after a long period of use, the battery on your proposal to initialize (detailed reference to the operation of laptop Manual).

Since the lithium-ion battery will pollute the environment damaged, but also a certain degree of risk. Please do not arbitrarily demolished, abandoned. Please contact with local authorities to understand that waste.

To protect the environment from the start I Environment Council Lu large collection of waste batteries

Nov. 9 hearing at 9 o’clock on Nov. 8, Eastern Shandong University School of Geography and Planning, Environment Council, held at the bridge used laptop battery  recycling, environmental protection, solidarity with the signing ceremony was also launched.

Activities, members of the Association of Environmental Protection to the students on the destructive power of the battery waste and recycling site used by students of used batteries. The event not only make students aware of the school the importance of environmental protection, but also become personally invested in environmental protection activities as a catalyst. I believe in the Environment Council of the efforts of environmental protection activities in the school can further develop.

Knowledge battery maintenance four: pay attention to other matters

To minimize the use of the number of batteries

The number of dell 2M400 battery charging and discharging a direct bearing on the life of each charge a battery to retire a step forward. If you often several times a day in Plug Power, and notebook computers equipped with a battery, battery on the greater damage. Because each access to external power supply is equivalent to charging a dell 2P700 battery , battery on the nature of the Zheshou. While the above theory of the case, but every time the battery is removed very convenient, plus no batteries, if all of a sudden power-down would lead to data loss. Therefore, we recommend that users do not have to use the notebook battery removed. However, if the customer would very much like to save the battery, the vast majority of the time or the use of power, but also to avoid the risk of power, you can choose to use an external power supply when the dell 312-0279 battery is removed.

After the exhaustion of power charge and avoid charging time is too long

After a long period of storagedell 312-0383 battery , dell 312-0386 battery , dell 312-3250 battery , dell 3149C battery , dell 3H625 battery , dell 3R305 battery , dell 4E368 battery , dell 4E369 battery , dell 4P894 battery , dell 5081P battery , dell 5208U battery , dell 53977 battery , dell 66912 battery , dell 6H410 battery , dell 6T473 battery , and battery discharge has a natural process, natural discharge has been finished, it does not affect the capacity of the battery.

The second battery maintenance knowledge: There stresses discharge charge

General rechargeable dell Latitude D800 battery  through a chemical reaction to store electronic energy, so it may be because the capacity of the temperature, not the length of time, load and the use of the environment and the number of affected. We usually get such a proposal, the use of dell Latitude D820 battery  power should always be used after all, so that notebook computers automatically shut down power to recharge every time must be filled.

However, the actual situation is generally used when the batteries need recharging when the computer prompts another charge, of course, prompts the time set, the default is 3%. Whether the use of laptop power lithium or Ni-MH battery, these batteries have been the memory effect, Ni-MH dell Latitude D810 battery   has a memory effect is obvious, but the lithium power will be the same memory effect, but its memory effect than Ni-MH small number of them. Lithium is no power on the memory effect that no more than exaggerated advertising business irresponsible behavior is totally misled. Since then the dell Latitude D830 battery  has a memory effect, charging it when it should be noted, as far as possible and then run out of charge, but there is no need to deliberate must say that the computer automatically shut down, so did not use up any harm (as with a notebook battery charge Discharge protection, the general notebook automatic shutdown is less than the standard dell Latitude PPL battery  discharge protection), but you do not feel so tired? In fact, less than 3% of the charge in this way on the good, there will certainly be the effect of memory, compared with the natural wear and tear, nothing should be.

Suggest you to the battery every few months to carry out a deep discharge the battery in order to optimize performance. This is accomplished through use of battery-powered, the  dell Latitude PPX battery capacity has been used to 0% (this time the system will automatically enter standby or hibernation state, according to the BIOS settings in different). And then connected to the AC charger has been full of up to 100%.

Tips: When the batteries are generally used in the computer prompts the need for re-charging charge, of course, prompts the time set, the default is 3%.

Full charge and discharge the right way is first of all in the Bios in the closure of energy-saving options, and then Windows “power scheme in” all elections are “never” and “alarm” option to remove the hook of all, when Electricity consumption about 5% of the left when to restart the computer, the screen display information based on self-keyboard Pause button to suspend and then shut down the screen to allow low-current dell Precision M65 battery  in the case of automatic discharge until the shutdown recharge, a charge that is fully completed.

To extend battery life, in daily use should pay attention to the energy-saving, you can Bios of power options “Maximum dell XPS M1210 battery Life”, in addition to the Bios you do not shut down a number of commonly used equipment such as parallel port, infrared, etc. ; Windows in the “power management” in the dialog box choose your power program; of course, some of the CPU can use the software so that the CPU cooling down to conserving energy.

Terms:

StandBy mode (standby): displays, hard drives, audio has been shut down. By Fn F3 operation.

Suspend mode (hang): All the tasks have been stopped and saved to memory, in addition to the memory of all the equipment outside have been stopped. By Fn F4 operation.

Hibernate mode (dormant): All the tasks have been stopped, and the current state of memory and hard disk to be stored in the system shutdown. By Fn F12 operation.

Battery maintenance knowledge of the cell to activate the new one

When talking about the use of new dell Latitude D500 battery , we often see this kind of perspective: “we buy a new battery, there will be more than 3% of the electricity, the battery’s power than is used up, until the shutdown, and then External power supply charge. Recharge time must be more than 12 hours, repeated three times to do in order to activate the cell. ”

Is this view is correct or not correct? In fact, most of the cases, we do not have been so troublesome to activate a new battery. This is because most of the brands in the factory when the dell Latitude CPID battery , dell Latitude CPIR battery , dell Latitude CPM battery , dell Latitude CPT battery , dell Latitude CPX battery have been completed and the activation of the work of the notebook battery factory with a bit of electricity to avoid natural wear and tear caused damage to the battery. The battery should be activated in the absence of the protection circuit of manner, with its own lithium battery circuit protection circuit, this circuit is designed to avoid over-charging and discharging of the battery, battery in a general, the charging indicator light to turn off time , On the battery charge is not into power, then you plug in the power plug on the face of rechargeable batteries to carry out what is the use?

From the dell Latitude D800 battery will be able to see the situation on the battery charge there, and teach you a simple way to be able to determine there is no battery during charging, the battery will have time to heat, when the battery is full after an hour (power Do not pull the plug), then you try the battery to see if the battery does not heat hot yet? The results must be cold, not because the battery charge and discharge status, of course, not heat.

Notebook makers in the factory when the proposed new dell Latitude D620 battery  for more than 10 hours. This may be the words so that some users have had the first wrong, this writer’s view is that notebook makers should be taken into account some new users to use a new battery when not fully grasp the skills of charge, so that they can simply charge 10 hours, so it should be the business expediency.

Tips: In fact, most of the cases, we do not have been so troublesome to activate some  new dell Latitude D505 battery , dell Latitude D510 battery , dell Latitude D520 battery , dell Latitude D600 battery , dell Latitude D610 battery .

MSI Wind NB 9 Cell Battery really emerged

Some people see before the Wind NB 9 Cell laptop battery  , although at that time with Annti official said no such plan, but has been able to buy on eBay in Britain, asking for a group of 115 U.S. dollars, equivalent to about RMB 786 yuan. Wind NB mounted, looks a bit small really fat, but the MSI Wind NB forum in which to get some people have a dell battery  , the actual testing of up to 7.34 hours, and good-looking than the DIY version of the more.

PS. It is said that this is very much like Sony battery  manufactured by Medion, as Medion has launched looked like the Wind NB light of the provincial electric pen, pulling even ~ ~ MSI is not officially out, and so on and after that they can ask Xiaobian Known.

The United States released a letter to monitor cell lithium-voltage electric current to protect IC for the main 5 to 10 units of the battery

More than 200,000,000 U.S. dollars to buy 10% stake in BYD shares phase battery God king In the oil sold in a year, Buffett once again the hand of Chinese companies

This time the goal is to BYD, and this is just the beginning.

Buffett said that can be used as BYD and the Chinese partners, the company is very excited. Wang Chuanfu, president of BYD are pleased to express the gratitude. 371786-001

Recently, in Hong Kong at a press conference, Buffett’s holding company, announced that China and the United States energy to 8 per share subscription price of HK BYD 225 million shares, accounting for its stake after the placement of 10%. The company will serve as Chairman of the  pavilion dv1000 battery  BYD’s non-executive directors.

Stealth champion on the road

“Life is like a snowball, the most important thing is to find a long and wet snow slope.” Buffett says he is doing.

In the United States in August on the CNBC host conducted an interview with Buffett, Buffett more than once referred to China, saying China’s economic prospects good, “I think China’s economy will not go wrong. From now on, 10 years , 20 years later,  08K8197  China and India is bound to rapid development. ”

In a lot of talk about China’s economic good, he also revealed that a single investment in China’s stock trading, Buffett said that  pa3285u-1brs  he had a Chinese bid for shares 500,000,000 U.S. dollars, but has not yet traded. In 2004, Buffett’s investment is 500,000,000 U.S. dollars to buy oil in a 3-year, he carried away 4,000,000,000 U.S. dollars.

A month later, the answers were revealed, BYD Buffett has become the latest wet snow.

BYD is why?

Buffett said that because of Wang Chuanfu have the unique ability to manage operations and good records  BYD further explained that the choice for three reasons: First, BYD high-quality management team leadership; Second, a strong R & D capability and  a1078  can be quickly developed into a product; three are widely Applies to all-electric cars, wind energy, solar energy, and other aspects of BYD’s fast charging technology.

Most people only know that BYD is a car, in fact, it is also the king of the world batteries. To become invisible in the championship on the road, BYD done entirely afford Buffett’s evaluation.

BYD was started in 1995, then left to the market, it is not a lot of opportunities. In products such as batteries, Japan in the 1990s is a rechargeable battery of  td175 a superpower, not to mention the Chinese people at that time, the Americans, the French people but the Japanese do. Human Japan is very expensive, so by way of the development of automation, a large investment.

Wang Chuanfu own a key assembly equipment, production inspiron 9300 battery  lines and then broken down into a number of individual workers to complete the process as much as possible in place of artificial machine. As a result, a significant cost advantage - the first production line BYD Nissan San Siqian a nickel-cadmium batteries  pcga-bp2v ,  only spent 100 million yuan. During the same period, Japanese manufacturers of production lines, investment in RMB equivalent to at least tens of millions of dollars. At that time, a lithium-ion batteries sold abroad, 10 U.S. dollars, BYD sold 3 U.S. dollars.

In the next few years, Wang Chuanfu quick to seize the world’s nickel-cadmium  g5266 battery market share of nearly 40%, BYD then replaced the Japanese companies, nickel-cadmium batteries into the sector “Big Brother”, BYD occupied for more than 70% The cell phone market and lay the foundation.

BYD’s other game is: to design and make up for absorption into the lack of such a strategy has been extended down.

In the auto industry, BYD will not do it from scratch a car, compared to the world’s leading platform to do, above board manner to imitate, who will have patent protection, such as the appearance of what the bypass will be over Protection of all useful techniques used. Automotive has developed more than 100 years, the patent has not expired, and the remaining patents is the appearance of a head-for-f3172a BYD, the end of a not-for-one on the patent, so there is no question of infringement. This is the F3 looks very much like a crown, but Toyota has not made BYD infringement lawsuit.

BYD has been a lot of vehicle design, cost even less than one-fourth of the others.

Wang Chuanfu management also has its own set of: “In the past, we only know how to control workers, engineers do not know how to organize themselves.   pavilion zd7000 battery ’Made in China’ is also a great advantage in the future, the key is to make good use of China’s high-and low-level human resources personnel, so Most of their play. Workers, high-pressure, the combination of high efficiency can play an immediate role, but the structure of knowledge, values and self-esteem is a very strong set of engineers in this matter is used. It is only through the establishment of cultural identity So that they can follow your ideas. ”

Wang Chuanfu by the end of 2002 when the Department of preparations for the cause of many such promises: “If any one can do business turnover of 3.0 billion, net profit 500,000,000 yuan, from a BYD will be able to share in the split off a separate listing of team Will be a huge incentive options. “BYD Electronics is one example. 8m815

Wang Chuanfu pursued, is to “Made in China” to play to the advantage of the full, and China’s human resources for the seamless combination. As a result, since its inception in 1995, a year in IT to maintain electronic components are 100% growth rate. Automotive industry groups have been maintaining a 100% growth rate.

Buffett has concluded: “Chinese people will do better because they are relatively low starting point. In the past 20 years, they learned a lot of business, as well as how the essence of human intelligence, although those in the United States as early as On the master. The key is that  g5345the Chinese people to learn the speed is very, very fast. ”

Rule the roost in the world dream

Dragged down by rising costs of raw materials, BYD in the first half of 2008 net profit year-on-year reduction of 7% to 596,000,000 yuan. As the global economy as a whole and the slowdown in demand for power tools market, BYD was the largest source of nickel battery product sales also fell by 15% year-on-year. At the same time, BYD’s auto business well in the first half of 2008, subject to the same period last year sales rose 94 percent driven by the business division’s turnover increased 71% year-on-year.

It is clear that the emphasis is BYD business to car.

Wang Chuanfu in accordance with the idea, in 2003 -2005, BYD is a foundation, build a platform stage that this step has been completed; 2006 -2008 is in a product, snatching share of the stage, this step is being achieved; 2009 — 2011 is the use of new technology to do China’s automobile industry leader.

Wang Chuanfu said that 2020 will be the world’s electric vehicles, electric vehicles BYD has mastered the core technology. BYD new energy F6 dual-mode vehicle for electric vehicles - F6DM will be in volume production in the second half of 2008, will be launched in mid-2009 pure electric cars. Dual-mode electric vehicles Wang Chuanfu was likened to “conventional weapons”, is a pure electric vehicle, he clutched the hands of a “nuclear weapons”, BYD will be lead by virtue of technology before other people and have a “release.”

Wang Chuanfu explained: “We are in the field of manufacturing batteries is the world’s top foreigners do not, we have done. The reason why the international electric vehicle failed to achieve any breakthrough, because the battery is experiencing high temperature above 150 ℃ will be an explosion. However, we have developed iron battery, capacity, efforts are very strong, but will not fire into the bombing. At the same time, is also in charge of technical breakthrough. Electrical car did not, portable charger can be used at home or Charge in the parking lot, just 10 minutes on the battery can be filled. You think about a price of less than 150,000 yuan, a necessary and sufficient power to run 400 km, 100 km of electricity consumption, only 15 of the listing vehicle, is it not In the international automobile market on the atomic bomb explosion? ”

“I believe that this product can change the world auto industry’s structure, or even to play down international oil prices! But also in the era of electric cars, engines and transmissions will be a thing of the past time.” Wang Chuanfu the future with hope.

It is understood that BYD is currently the national power grid and Southern Power Grid, as well as on the power station construction projects to communicate. BYD Co., Ltd., general manager of auto sales this summer ice explained: “The electric vehicle market in the early, as the cost of the relationship between the price will be higher. BYD is indeed present in the State Power Grid and Southern Power Grid to discuss co-operation to enable BYD related to the future of free or low-cost model for charging, to reduce the use of cost-DM model. BYD is also out of a long-term strategic considerations, in the hope that the DM project to find new partners. ” VAIO PCG-R505AGTVAIO PCG-R505AKVAIO PCG-R505B/PVAIO PCG-R505BFVAIO PCG-R505BWVAIO PCG-R505CTVAIO PCG-R505DVAIO PCG-R505DFVAIO PCG-R505DFKVAIO PCG-R505DFPVAIO PCG-R505DLVAIO PCG-R505DLKVAIO PCG-R505DLPVAIO PCG-R505DSVAIO PCG-R505DSKVAIO PCG-R505DSPVAIO PCG-R505DTVAIO PCG-R505DXVAIO PCG-R505EVAIO PCG-R505ECVAIO PCG-R505ECKVAIO PCG-R505ECPVAIO PCG-R505ELVAIO PCG-R505ELKVAIO PCG-R505ESVAIO PCG-R505ESKVAIO PCG-R505ESPVAIO PCG-R505EXVAIO PCG-R505F/BDVAIO PCG-R505F/SPVAIO PCG-R505FRVAIO PCG-R505FR/DVAIO PCG-R505GVAIO PCG-R505GCVAIO PCG-R505GCKVAIO PCG-R505GCPVAIO PCG-R505GKVAIO PCG-R505GLVAIO PCG-R505GLKVAIO PCG-R505J/BDVAIO PCG-R505JEVAIO PCG-R505JEKVAIO PCG-R505JLVAIO PCG-R505JSVAIO PCG-R505KVAIO PCG-R505MFVAIO PCG-R505MGHVAIO PCG-R505MPVAIO PCG-R505MXCVAIO PCG-R505Q/BVAIO PCG-R505Q/BDVAIO PCG-R505RVAIO PCG-R505R/AKVAIO PCG-R505R/DKVAIO PCG-R505R/GKVAIO PCG-R505R/KVAIO PCG-R505S/PSVAIO PCG-R505SPVAIO PCG-R505TEVAIO PCG-R505TEKVAIO PCG-R505TFVAIO PCG-R505TFPVAIO PCG-R505TLVAIO PCG-R505TLKVAIO PCG-R505TSVAIO PCG-R505TSKVAIO PCG-R505TXCPVAIO PCG-R505TZCPVAIO PCG-R505V/BDVAIO PCG-R505VJ/KVAIO PCG-R505VM/KVAIO PCG-R505VM/PVAIO PCG-R505W/PVAIO PCG-R505W/PDVAIO PCG-R505X/PVAIO PCG-R505X/PDVAIO PCG-R600VAIO PCG-R600HFPDVAIO PCG-R600HMKDVAIO PCG-SRVAIO PCG-SR1/BPVAIO PCG-SR11KVAIO PCG-SR17VAIO PCG-SR17DVAIO PCG-SR17KVAIO PCG-SR19GVAIO PCG-SR19GTVAIO PCG-SR1C/BPVAIO PCG-SR1G/BPVAIO PCG-SR1KVAIO PCG-SR1M

At the same time, but he acknowledged that BYD and State Grid, China Southern Power Grid of the relevant contact, no substantive progress.

In addition, the current domestic market DM models, will be part of the policy limit, in order to promote a large area are still difficult.

Wang Chuanfu would like to doze off when due, Buffett gave up the pillow.

Wang Chuanfu excited that Buffett’s investment company will have a major impact on the promotion of the brand, you can speed up the electric vehicle research and development and promotion, particularly in the North American market. He further explained that: “BYD itself very much like to find a long-term strategic partners, particularly in the United States. Commercialization of electric vehicles has always been our dream. In North America, relying on Buffett and his companies Reputation, together with China and the United States with the help of energy, BYD can more quickly realize this dream. “He also said that China and the United States energy in a wide range of U.S. energy networks and power distribution network can help BYD in the future of electric vehicles in the United States Charging station facilities.

Wang Chuanfu said: “BYD will be the new energy vehicle in North America and Europe as a stepping stone market. We welcome Mr. Buffett is also an important investment in one of the reasons why he can to speed up investment in North America BYD new energy vehicles Promotion. F3DM we will be dual-mode hybrid power cars and pure electric cars to enter the European market, plans to test in 2010, officially launched in 2011, and in the United States and market development to keep pace. ”

Wang Chuanfu Buffett is the real reason to welcome, not just those 230,000,000 U.S. dollars. Wang Chuanfu said that the Sino-US energy put forward by the beginning of a greater amount of investment by Buffett’s is 500,000,000 U.S. dollars, “but we take into account the company’s capital needs and development, ultimately we have to respect the requirements”, formed 8 Hong Kong dollar per share to purchase 225 million shares BYD shares of the final plan.

“Do not hesitate to say that China’s labor advantage is not as developed countries, and we do the battery, start with the human costs of Japan beat the opponent. Do cars, or take advantage of our human defeat competitors. Because of the car Process the vast majority of people still do.’s Hard work and hard-working Chinese people, our decision is bound to become the first in the world. “Wang Chuanfu very confident.

“2015 sales of 1,440,000, becoming the first Chinese passenger car sales market”, “2025 sales 13,360,000, as the world’s first passenger car sales market,” … … 2025, to go beyond the BYD Toyota, one of the world’s largest car manufacturer, and this is the dream of BYD.

Buffett’s investment will accelerate the realization of this dream it?,02K662702K663202K663302K664402K664502K664702K664802K664902K665102K665302K668702K669002K669102K671002K674002K674102K674302K675802K676002k676202k676302K682102K682202K682302K682402K682502K682902K683002K683202K684502K684602K691902K692302K692402K692802K701602K701802K702202K702502K702602K702802K703402K703702K703802K703902K704002K705002K705102K705202K705302K705402K705502K705602K705702K705802K705902K706002K706102K707202K707308K802408K802608K803508K803608K803908K804008K804508K804808K818208K818308K818408K818508K818608K819208K819308K8195

New type of silicon solar cells, such as portable carpet

Recently, the United States, University of Illinois at Urbana - Champaign (University of Illinois at Urbana-Champaign) of the John Rogers (John Rogers), led by scientists discovered a new high-efficiency silicon solar cell production. This means the production of silicon solar cells is the flexibility and scalability to roll in pencil, a transparent and even as the building and automotive glass windows of colorants laptop battery  .

Published in the online journal “Nature - Materials” (Nature Materials) on a report that a new type of method can be used to the traditional silicon processing, is about to cut crispbread fragile silicon micro-thin ultra-fine Silicon, and then carefully transfer them to another extension of the flexible material on the surface.

The new leader of the research Rogers said: “We can make super-thin silicon can be attached to the plastic on any curl. Can also make silicon thin film or a film-like, glass, construction incorporation. This Building for the use of solar battery energy has become a platform opens up space. ”

As the global oil prices, coupled with people’s concerns about global warming, greatly increased the demand for solar cells.

Many of the world, such as Japan consumer electronics maker Sharp Corporation (Sharp Corp) and the German photovoltaic cell giant Q’s (Q-Cells) have a thin film solar cell production, however, this type of thin film solar cells in solar energy will be converted to electrical energy On the general efficiency of less than traditional solar cells.

Rogers said the technology used in the traditional silicon, they are “rugged, high efficiency, however, now appears to be too rigid and therefore fragile.” Rogers they adopted a method of etching silicon to deal with these Hp battery   . In a large silicon surface Guaxia small debris, the debris than the thin silicon wafers would also like to book 10 times to 100 times, and because of the small size, more user-friendly.

Guaxia silicon debris, the equivalent of a “rubber stamp” of these devices Zhanqu debris, and then they will be “printed” into other substances on the surface.

Rogers said: “These Guaxia Lai silicon debris as ink. Guaxia debris after the big silicon thin silicon surface has become the ’stamp pad’. Just ’seal’ to ’stamp pad’ in the silicon debris’ India ‘to other objects to the surface. ”

He said that as long as the final step in the electronic equipment used in solar cells will power Export it  HSTNN-LB31 .

Silicon material to increase the flexibility of making silicon solar cells more lightweight, easy to carry. Rogers looking forward to the future of silicon solar cells “can be rolled up like a carpet into the same truck.”

He said that the newly established North Carolina’s Durham County Semprius is the registration of the technical consultation.

Rogers said: “We only change the way we have the advantage of familiar things.”

Thin film solar cells into a new investment hot spot to open up the sun’s Road

In April 2008, Xiasha in Hangzhou Economic and Technological Development Zone, a petty building, Long Yan Energy Science and Technology (Hangzhou) Co., Ltd. was established. The total investment of 24,000,000 U.S. dollars of the company to do things very advanced: CdTe thin film batteries and components can be. Although their product is still in the stage of research and development laboratory, to be formally put into operation in 2009, they set up in the company to get on the first day of the domestic venture capital investment  ThinkPad R50 battery   in Lenovo’s big money, and Legend Capital Partners for the “Success” is very happy to invest.

Yan Lung, and the low-key, Chint Group for investment in solar constant media attention. Zhengtai production of thin film solar cell Tablets available by the end of 2007, to the present capacity of 100 megawatts. Managing Director of Solar Zhengtai Yangli You are expected by 2011 will reach 400 megawatts of capacity. “The market demand, supply, a product line has been taken away,  PA3383U battery   completely a seller’s market!” Pleased Yangli You anomaly.

Silicon thin film battery supply crisis led to investment

In fact, as early as the 1970s, amorphous silicon thin film  Pavilion ZV5000 battery   was developed, but due to the conversion efficiency of polycrystalline silicon is only half has not been universal. In recent years increasingly favor the photovoltaic industry, triggered a crisis in the supply of silicon materials. Silicon raw material prices, making cell membrane surface again. In 2007, the world’s thin film solar cell output to reach 400MW, over 181MW of 2006 increased 120% market share in 2006 from 8.2% to 12%.

Accordingly, the following components of   ThinkPad T20 battery  solar heat, heat polycrystalline silicon, thin film photovoltaic cells and become a new investment hot spot in the field. In June 2008 the German Photovoltaic Exhibition, 2008 with an annual output of Taiwan can only 30MW of green energy, to be signed orders amounted to 200MW, is an annual output of 2008 to 6 times; Yutong energy production yet, have also made orders 60MW. Tianwei change security plans to invest 3.2 billion for the A1012   amorphous silicon thin film solar cell projects; Zevi announced in Nanchang, Jiangxi building the world’s most technologically advanced and largest thin film solar cell projects; in July 2008, Johnson & Johnson non-25MW photovoltaic Crystalline silicon thin film solar cell production line officially put into operation; Jiangxi be able to announce the formation of joint stock companies, the goal of building capacity for 50MW of amorphous silicon thin film photovoltaic cell production line. Prior to this, Suntech, Vosges stake in the new extension to that variety, such as shares of the company have also announced to enter the field of thin film batteries.

Benchmarking Enterprise First Solar

Many types of thin film solar cells, contains the main types of silicon thin film (amorphous silicon a-Si, Si c-Si, stack-a-Si / c-Si, etc.) and compound semiconductor-type (copper indium gallium selenium CIS / CIGS , Cadmium telluride CdTe), and the new concept of the type of dye-sensitized.

Although the film solar cell market share of less than one-cheng, the conversion efficiency of the production yield, equipment costs and other issues have to be overcome, however, save a thin film solar cell material can be inexpensive glass, plastic or stainless steel substrate To create, large-scale manufacturing, can be made of flexible, easy to work with the external walls of building construction applications, such as flexible benefits, has been widely the solar industry, research institutions are good, it will be the next generation of     VGP-BPS9/B  solar-Star Products.

Sino-amorphous silicon thin film technology to solar cells for the largest, and cadmium telluride solar cell production growing the fastest. In 2006 the world’s top 15 largest solar cell manufacturers, only 13 of the top of the First Solar is a production of cadmium telluride thin film solar cell business. The company is headquartered in Arizona, the current thin film battery products in short supply, orders scheduled to post in 2010; its share price in a year and a half rose nearly 10 times that of the U.S. market to enjoy the highest level of valuation of the shares of PV  Pavilion ZV5000 battery  .

First Solar is higher than 50% of the gross margin, but such a high gross margin due to the company’s grasp of the cadmium telluride thin film of the core technology of its own equipment for the design, technology has developed, so the cost is much lower. From the breakdown of the costs also can verify this, even though First Solar equipment depreciation period of five years, the middle class than the other U.S. AMAT Applied Materials of 7 years shorter, but the unit cost of depreciation than AMAT’s amorphous silicon production line 20% more than in the AMAT laminated production  9T119   line for more than 40%.

“First Solar in the world of film producers set a good benchmark, but it is impressive indicator is not General enterprises and the enterprises can easily.” Country gold of the new energy industry securities analyst, said Zhang Shuai.

Space great concern both

Experts believe that with crystalline silicon cells, thin film battery cost is much greater potential decline, mainly due to the thin film battery technology are advancing rapidly. According to the “Photon” forecast, the average price of polycrystalline silicon components from the end of 2007 of 3.92 U.S. dollars / W in 2012 dropped to 2.08 U.S. dollars / W, thin film batteries from the current average price of 2.65 U.S. dollars / W fell to 1.11 U.S. dollars / W, with the obvious advantages compared to crystalline silicon.

As the cost of the decline in the industry estimate, to thin film solar cell in 2010 will be better into the development of mass production, market share will be raised to about 12% -20% of the total output of up to more than 1GW.

“Solar is expected in the future of film production could reach throughout the solar industry’s 20 percent, only 7.6 percent, which can be seen in this space.” Huarui Zhejiang Investment Management Ltd. investment manager Zhang Bin: thin film solar is to do thin, To improve the performance, there are a lot of physical methods, such as ion beam deposition method of nano-crystalline silicon thin film technology that, in the only foreign company doing, there is no home. If domestic enterprises to upgrade some of these  ThinkPad T40 battery  above method will be very promising.

Zhang Bin, as mentioned, domestic enterprises are technically still a great gap. And the crystalline silicon cells are quite different from the thin film battery manufacturing, such as wider use of vacuum coating technology, like the semiconductor industry, so a direct impact on the level of technology products yields has indirectly affected the profitability of enterprises, from this major LCD Plant, IC manufacturers, the profitability of the great differences can be seen slightly; Second, the thin film battery industry is a technology innovation and development of industry, technology and some routes are not yet ripe, so from the need to continue to improve the technology point of view, thin film batteries Battery makers than the crystalline silicon manufacturers need a strong R & D and technology team.

In addition, the thin film  battery  F1739A  technology development due to a shorter time, did not form a common technology and common equipment, the provision of the current large-sized thin film battery devices turn-key projects mainly in the United States Applied Materials (AMAT), Switzerland’s Oerlikon, as well as three of Japan’s ULVAC . Film equipment depreciation is the cost of one of the main battery, according to market quotations, with the capacity of the thin film battery production line is the price of the silicon crystal 6-10 times, and the main suppliers of raw materials, are currently the monopoly of the international giant, high prices and without Security.

The main raw materials, thin film batteries include glass (conductive glass and other glass), EVA, as well as the target gas. ITO thin film battery on the higher, current weak domestic manufacturers, the market mainly from Japan and the United States AFG divide up the NSG. With the outbreak of the domestic film production, is likely to tight supply situation. The current target the domestic supply is still dominated by large international companies, Heraeus Germany is the world’s largest supplier in the domestic market share of over 60%. In addition, there is no domestic production of silane, while the large international companies, mainly limited expansion, coupled with high demand for LCD and so on, silane supply side is still tight, prices will remain high does not rule out the possibility to continue to rise.

Of course, from another point of view, the domestic enterprises if they can break through bottlenecks in the development of these naturally will have a very strong competitive edge. In the current crystal silicon solar energy prices high, thin film solar cells usher in a good development opportunities, market demand increasingly strong. However, if the next crystal silicon solar energy prices fell sharply, thin film solar cell market demand for   PowerBook G3 battery  products that might be affected. Experts advise investors, it is important to note that the market risk.
