Reporter learned from the high-tech zones, to fill gaps in Sichuan Province, “Lithium iron phosphate nano-projects” in the trial has been completed, and the formation of 600 tons / year capacity; and nano-lithium iron phosphate batteries is a major manufacturer of high quality raw materials.

It is the key to battery

Chengdu a few days before the public shouted can not stand the high temperature, and in the future, the hot sun can actually become your home-based free energy, provided that as long as you have enough storage capacity, performance and stability of the battery and the energy collection device on the line the. The production of such batteries is dependent on an important part of it – fine of lithium iron phosphate.

“All the batteries are from the cathode, anode and electrolyte composition; and lithium iron phosphate cathode material is the most important. Through wind, solar electric hair is very unstable, very demanding on the battery. By the nano-phosphate iron lithium battery cathode production of high quality, sufficient capacity, stable performance can be achieved without sufficient light hair light and memory, especially for domestic use. “” Lithium iron phosphate nano-projects “to the reporter, Huang responsible.

To fill the gaps in Sichuan Province

Reporter learned yesterday from the Sichuan Provincial Science and Technology Agency, “nano-lithium iron phosphate project” to fill the province’s quality and stability can not be mass-produced lithium iron phosphate blank. The project used in the world currently the most advanced production technology, to solve the current domestic and Jun use traditional methods of high cost of lithium iron phosphate, heavy pollution and mass production capacity Nan Yi Yi Jibi control, Liang Producing, Zhi Liang Wen Dingxing poor major scientific and technological problems. The product used in lithium battery with a ratio of large capacity, high discharge power, quick charging and long cycle life, high stability, the advantages of the new materials, new energy industry development is important.

Output of up to one billion next year

This reporter learned that, in the lithium battery industry chain, market capacity of the largest, highest value is as a cathode material lithium iron phosphate, lithium battery costs accounted for more than 30%. According to the latest statistics, the domestic lithium iron phosphate cathode material for hundreds of companies achieves mass production, nearly 20 enterprises, and China’s actual capacity planning 1,200 tons. According to industry analysis, the global lithium irons phosphate actual demand more than 150,000 tons, 10 tons of supply and demand gaps. According to China’s “auto industry restructuring and revitalization of” the development goals and the Chinese Market Intelligence Center (CMIC) predicted that 2012 needs 50,000 tons of lithium iron phosphate, need 250,000 tons in 2015, 2020, requires 760,000 tons of iron phosphate lithium.

Currently, high-tech zones in the city’s “Lithium iron phosphate nano projects” have been completed in the trial, and the formation of 600 tons / year production capacity of lithium iron phosphate, to the end of this year early next year will create 3,000 tons / year production capacity, Jie Shi The annual output can reach 12-17 billion (at current prices of similar products); expected to reach 2014, the scale of 100,000 tons annually.

Whether the realization of large-scale production of lithium-air battery, and lithium ion batteries in electric vehicles haven’t room for survival? The answer is clear who will select more than energy, lower cost lithium-air battery. As some experts said that vehicle battery, battery technology research and development in China, to take account of the moment, but also to look to the future.

Currently, the industry has become China’s new energy vehicles to work together. States on the purchase of new financial vehicles for private users of energy subsidies are well-intentioned. R & D in batteries is mainly to meet the current needs of industrialization. R & D from the domestic battery situation, R & D efforts focus on the traditional battery, battery technology, upgrading of trying to improve the specific energy, in order to increase driving range.

At present, there is concern that the traditional bottlenecks in battery technology has encountered some pessimistic even assert that the new energy vehicles in China into a dead end. Despite the fact that not so bad, but the technical reserves for the future, we have not done enough. The author believes that adhering to traditional battery technology developed at the same time, we should look to the future. Such as Japanese-developed lithium-air batteries, although difficult to achieve large-scale production in a short time, but look at their performance, no doubt can play a role in the future.

With rapid technological change and indifference, Looking back at the history of science and technology, a new technology has been updated technology out examples abound. New energy vehicles as China’s emerging strategic industries, the key components, one should learn to avoid such incidents. R & D in battery technology should always follow the leading edge technology; intensify technical reserves to meet future competition.

Lead-acid battery with its simple manufacturing process, raw materials, abundant source of affordable power supply in the secondary chemistry plays an irreplaceable role, in particular the emergence of valve-regulated batteries battery has the traditional glow of vitality. Battery life is closely related with the manufacture, and use the same time have great influence, the correct method to master the use of great benefit to extend battery life.

The traditional open-type batteries routinely on the following aspects NOTE:
① electrolyte quantity, density and charge level of attention and so, in particular, is closely related to the charging system with special care, if the battery charge level is greater water loss is more likely to cause the active material off the plate, causing the bottom of the short circuit to shortened battery life of the internal temperature is high, if the amount charged less likely to cause the battery’s loss electric, battery electric Zaichangqikui of situations, which can lead sulfate plate irreversible Hua, manifests itself Chongdianguocheng fast voltage Shangsheng , to complete a very short time, discharge voltage decreased rapidly.
② electrolyte purity, generally use the battery electrolyte, or add special fluid infusion, non-replaced with normal sulfuric acid and water.
③ the surface clean for everyday use, the exhaust port flow.
④ not be the first place full of electricity, while three months to conduct a supplementary power.

The sealed lead acid batteries are routinely on the following aspects NOTE:
① attention to the scope of float charge voltage when the voltage is usually controlled using 2.15 ± 0.1V / single cell, recycling of general control when the voltage at 2.35 ± 0.1V / single cell, if there are requirements specification should be instructions.
② Note the use of ambient temperature, generally not more than 30 degrees is appropriate. Higher temperature should enhance the voltage regulation.
③ products for different manufacturers can not be mixed, the same can not mix old and new product manufacturers.
④ sealed lead acid battery is best not to open the lid to add your electrolyte and replace safety valve.

Attaches great importance to the global climate change and carbon reduction trend in renewable energy, electric cars, as well as the promotion of smart grid has become an international trend. Also led various large-scale energy storage and power battery market. Battery materials in Japan, buttressed to Cell’s technological advantages in the development of large-scale energy storage quite positive. A 2009 deployment position, the nearly 90% of the energy storage in Japan are set in, as shown in Figure 1. The Battery Japan in the show, many manufacturers have exhibited a variety of large-scale energy storage battery. Moreover, in addition to large-scale energy storage, the text will be referred to other new trends in technology and product applications.

METI to apply to various types of large energy storage battery, points out the focus of future technological development. In addition, and add “technical difficulty”, “charge and discharge rate”, “price” to further clarify the characteristics of various types of energy storage batteries. Japan’s industrial economy for the province of large energy storage battery options related mainly nickel-hydrogen batteries, sodium sulfur batteries, lithium ion batteries, super capacitors. Present the case of the actual deployment to the highest percentage of sodium sulfur batteries, estimated in 2010, about 64% of the world, nearly 160MW of capacity deployment.

In addition, other cells have different characteristics, such as: have a price advantage of the nickel-metal hydride batteries, the super high-speed charge and discharge edge capacitance. The lithium-ion battery, there may be extensive use of the car battery under the low-cost through economies of scale pull into the large energy storage applications. In addition, in this exhibition, we also found that some vendors have applications in large-scale lithium-ion battery energy storage. Overall, each type of batteries have their own advantages and disadvantages, its characteristics must find a suitable energy storage applications.

(A) Shin-Kobe Electric (Shin-Kobe Electric Machinery Co.)

Shin-Kobe Electric, Hitachi manufacturing department is responsible for the production of industrial lithium battery division. The display in the large energy storage battery is more special, LL-W type of large lead acid storage battery. This module Besides general storage function, but also can be used to ease the wind power system activated, the resulting system instability. Overall standard size 437 × 799 × 500 mm, voltage of 8V, the current up to 1500Ah, electric capacity of 12kWh, priced at 400,000 yen. A single branch about 2MW wind power generation group based around electric devices need 1.3MWh reservoir, so the overall projected LL-W module, about 432. And the Kuroshio current (Kuroshio) wind power companies have actually set up in Aomori Prefecture goshogawara city to match the total 16MW of wind power.

In addition, the Shin-Kobe Electric is also responsible for the storage of display the battery power module-LL (available for solar or wind power) modules and LL-S (for solar) module. Different from the LL-W-type module is configured to wind or solar 99kW 100kW of power generation equipment, the will with 584kWh energy storage battery, converted into the module takes about 292 LL1000, the overall battery energy storage equipment, build, budget of almost 6,000 million yen.

(B) ELIIY POWER

ELLIY POWER is in Japan, quite a large lithium-ion batteries are promising energy storage company. First by the Keio University in 2003 in a ELiica electric vehicle project initiated and nearly 30 companies one after another joined in this project. Later in 2009, from Sharp, Japanese housing industry and other enterprises to raise funds for the establishment of 10.16 billion yen, and publicly traded. And in the same year announced the establishment of lithium-iron battery technology will be used for home and factory and other large storage needs. Which will be Sumitomo Osaka Cement (Sumitomo Osaka Cement Co., Ltd.) Lithium iron phosphate cathode material provided powder. The Sumitomo Osaka Cement, lithium iron phosphate in the bullish outlook, will significantly expand production capacity, expected in 2011, the lithium iron phosphate from the original 1.5 million tonnes, a substantial increase to 1,000 to 2,000 million tonnes.

Figure 4 for this developing field ELIIY POWER shown large energy storage related systems. The main battery module, containing four lithium batteries Cell. Module specification for the 192 × 175 × 128 mm, weighing about 2kg, the energy density of 91 Wh / kg. Figure 4 on the left of the EPSS 8kWh system requires 8 modules.

ELIIY POWER 2010, will produce 200,000 lithium-iron battery Cell, mainly for large-scale energy storage. In addition, the lithium-iron battery energy storage module in practical settings, the majority of working with local governments, set in schools, local administrative institutions, other private adoption rate is very low.

(C) MAXWELL

MAXWELL, in this exhibition, the exhibition 3C and hand tools, many of the lithium-associated module.

Most eye-catching, comes as a super capacitor used in large-scale energy storage module. This BMOD0063P125 module, due to the characteristics of high-speed charge and discharge. Application of the following two conditions. First, the general large-scale wind power and lifting equipment, this module can be launched to provide the required high current moment. Or when a large number of power generation currents, this module can be follow-up storage device buffer.

In general, single-group 2MW wind power generation equipment, just need a super-capacitor module. This module, for example, contains 18 super-capacitor Cell, the overall module size, as shown in Figure 6, size 619 × 425 × 265 mm, voltage up to 750V, maximum current of 750A. But the unit price is quite high, about 405,000 U.S. dollars.

(D) others

Other large energy storage battery module makers have related products on display. Large energy storage battery option will be to compound combinations. In general, large-scale renewable energy storage device and carry quite close. Operation of renewable energy power generation, for energy storage devices, also have different functional requirements. To wind power, this can be divided into “instant activation” and “Hang Time Energy Storage” in demand, as shown in Figure 7. The “instant activation” of the demand, the attention is the instant charge and discharge energy storage devices and high security. The “permanent storage when” the focus is the stability of stored energy and lower security requirements.

In the exhibition of large energy storage battery related to the process of inquiry, the whole unit can be found in the gap is quite big. Therefore, we can expect large-scale energy storage to build the future of the process. Will be a combination of hybrid batteries.

Currently speaking, the instantaneous charge and discharge efficiency, super-capacitors, or preferred, but the unit price close to NT 10 million. May make a single renewable energy devices, will only carry a super capacitor module. In addition, very recent topic of ternary cathode material of lithium battery vehicle, in its performance under high efficiency may also be used in “instant activation” requirements.

Finally, in “Hang Time storage” aspect, in the setting of limits, the energy requirements and battery performance is not as harsh automotive lithium batteries. At present, we find that firms tend to use less expensive battery types, such as lead-acid batteries, nickel-hydrogen cell. The lithium-iron batteries, lithium batteries are hoping in the car driven by economies of scale, the unit price can be lowered, to apply to large-scale energy storage.

100 years ago, electric vehicles and internal combustion engines of the vehicles had already been life and death battle, the result of the great advantages of assembly line production for internal combustion engine vehicles in winning the world. Today the general trend of the evolution, the world was the battery bidder. Which is considered the heart of high-performance lithium battery electric vehicles has attracted world attention. Dominant position in this competitive world market, China, the United States, Japan, exactly who the winner … …?

Hit the market at low prices

Early 2010, Jiang Su Yimao 100,000 electric vehicle production base in the country’s first vehicle built. Yi Mao is specialized in lithium technology, Dr. Chen Henglong had founded in America, so far, but two or three years time. Chen Henglong far from his twin brother, big fame Shi Zhengrong, who is chairman of Suntech Power Co., Ltd., has become the industry leader. Prior to this, Mao did not benefit the experience of the production car, its main product is a large lithium battery bus lane. Yi Mao, however, in just three years, the use of the Government’s strong policy of supporting new industries spring growing rapidly. This year in April, it has even become Japan’s NHK television reported that the main target tracking. In Chen Henglong seems that the time is excellent, in large factories, the inroads into the industry before the shot quickly capture the market, before the matter is clear occupy certain market share, is necessary.
Not difficult to see, in Chen Henglong eyes, as if this difficult decision into a single answer, but the market is the single answer correct answer. It is undeniable that, the benefits of Mao’s power battery production did not reach the advanced level of developed countries, the manufacturer, but the price is still low but it has a competitive edge. All in all, intend to seize power as soon as possible with a low price battery market is not limited to domestic private enterprises.

This year in April, SAIC and the U.S. battery maker A123 Systems Inc. joint venture to establish “a new battery Shanghai Czech Republic Systems Limited.” The United States that, with China’s cooperation is the key to cost control, China’s materials, cheap manufacturing base Yong You, Lao Dongli, adequate 生产 equipment and complete supply network, which all products are Jiang Shi Zai markets are highly competitive prices. In fact, the low price has long been the advantages of the battery manufacturing industry. According to China’s Development Research Center of lithium to a report, the US-Japan R & D in technology companies leading the pursuit of technology is different, Chinese companies are very focused on practical application of technology research and development. In other words, Chinese companies first consideration is cost, followed by advanced technologies. Few industries can give China a chance: with the major Western competitors start standing on a starting line at the same time. To include a new energy industry, including lithium batteries are just that. Although the United States A123, Ener1, Johnson Controls and Toyota’s Panasonic EV Energy Holdings holds claim to cutting-edge technology in this industry, but according to the Irish business consulting firm Research and Markets lithium battery market report released last year show that China in the field production has reached the world’s largest, and more than 1,500 lithium batteries and battery materials manufacturers to compete. China determined to become a global leader in electric vehicles, giving priority to occupy the market rapidly, reach a certain level of quality after the introduction of cheap, Chinese companies vying for market share has become a development strategy of hegemony.

Win the trust of the market with high quality technology

Back in 2008, end of the year, Honda and well-known battery manufacturer GS Yuasa joint venture to promote the development of lithium batteries. “The battery is fully part of the chemical field, we do not quite understand, must work with others. As for the car’s use of the environment, some technical details may be known only to us. 10 years of experience in car battery, and only two of us with Feng Tian This 10-year experience can not be bought. “This is a Honda mechanic told NHK television interview to make the statement.

Sanyo Japan introduced a solar charger, this charger itself is called soila with a USB interface to connect the computer to charge the battery. The alkaline battery charger can be said on the 3rd charge, for the 1-2 battery is fully charged needs about 150 minutes or so, if it is three or more of the alkaline D5318 battery is required for more than 300 minutes, while a lithium ion battery is fully charged requires 6 days time. In addition, soila solar charger can also be connected to the computer through the USB interface to recharge the battery, from the above description can be seen, this so-called solar charger only light there is gimmick fills mainly through the USB interface charge.

soila shape size solar dell KD476 charger 160 × 180 × 70mm (width × depth × height) and weighs about 550g. Priced at 20,000 yen. Synthesis of the yuan at about 1320 or so far.

Today, electronic products and digital products favored by the majority of the people, because it brings to life a lot of convenience, while enjoying the convenience of these products battery problem has plagued us, and therefore the maintenance of these products are dell vostro 2510 battery  battery aroused our attention, I will brief the following three types of laptop battery maintenance methods.

1, activate the new batteries let your laptop battery longevity, there must be a good start, which was talking about from the purchase of notebook. New laptop battery at the first boot with a 3% charge should be (this is the general practice firms. If you first open the purchase of notebook and found that the battery is full, is certainly used by others up), this time, you should first do not use external power to battery power exhausted in the remainder until the shutdown, and then use the external power supply charge. After returning home, even after the exhaustion of the battery charge, charging time must be more than 12 hours, repeated three times to activate the Dell Inspiron E1705 battery  , in order to lay a good foundation for future use.                                                                                                                                                                                                      

2, to minimize the number of battery seems to be some people feel this way stingy, but it is also the most effective. To know the number of battery charge and discharge directly to the life of a single battery charge, battery on a step forward to retirement. Suggest that you use an external power supply, use an external power supply when the battery removed. Some friends of convenience, often several times a day plug in the power supply, and laptop computers equipped with a battery, do more damage to the battery. Because each time access is equivalent to an external power supply to charge the  Dell Latitude 131L battery once the battery life shortened by a naturally.                                                                                                          

 3, battery charge and avoid exhaustion after long charging time regardless of your notebook to use nickel-metal hydride or lithium electricity, to power must be exhausted after the full (capacity less than 1%), it is best to avoid the memory effect Methods. No memory effect on lithium argument, I note in front of businesses irresponsible been misled. Lithium also have memory effect, but it is the memory effect than Ni-MH smaller Bale. And battery charging in the same way, when you charge the battery to the laptop, try to avoid too long, the general control within 12 hours. As for the prevention of exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with the Dell Latitude D610 battery  contacts and metal objects such as notes, not much to mention here also.

Finally, it is worth, no matter what kind of products of batteries bursting or other causes of fluid outflow or leakage, make sure to replace the battery, otherwise we would not only damage the product itself, or even the user’s body products have a certain hazard function.

Qian Zhao company is a few of the high brightness LED chips quaternary is the most mass-produced three-junction GaAs solar cell chip vendors.

Quaternary bright red, yellow LED Dell Latitude D620 battery  application fields and market growth, import substitution in a large space. 2012 global high-brightness LED market will reach 11.4 billion U.S. dollars, quaternary LED will account for 30% of them.

Recently, Matsushita announced that it will completely take over Sanyo Electric. Sanyo has announced the suspension of the company’s production of thin film solar cell program, which originally planned in the production of thin film battery is scheduled for this year. Sanyo’s efforts currently focused on its original battery product efficiency and market vitality. The change in the plan: the reasons for the company’s words is due to crystalline silicon cells continue to lower prices, photovoltaic market environment of the “dramatic” change.

In the open letter, the company wrote: “Since the Sanyo Solar Sanyo Electric and Japan by the oil companies in the January 23, 2009 joint inception, the PV market had a dramatic change. In the PV power plant competitive with thin film batteries crystalline silicon cells main competitors lower costs as raw materials, finished goods prices plummeting. stimulated greatly weakened the competitive advantage of thin film batteries.

“Thus, Sanyo and Nippon Oil conclusion should stay its parent company, Sanyo Solar of production expansion plans and shifting the focus to improve the market competitiveness of the company up.”

Meanwhile the company also mentioned that the original Sanyo Solar of all employees last month to return to their respective parent companies, respectively.

Countries to develop new energy subsidy policy, said: meet the requirements of consumers to buy a pure electric vehicles the state will subsidize 60,000 yuan.

This news release can be said to a ripple, a time of thunder Hong Hong, electricity glimmers, on to government officials, experts and scholars, down to the factory, the media, talk of nothing will talk about “electric vehicle” can be said a “hymn and saliva,” Qi Fei, faction bustling scene. Separate ways “heroes” are punched smoothed sleeve, one of China’s new energy vehicles for the cause of “work hard” “offering words and ideas,” the spectacular Zuopai.

However, in the lively behind is an opposite scenario.

Today, two months have passed already.

After the first increase both price cuts, a self-”new energy drama” of BYD, or other claims of new energy technologies are already mature car prices, car enterprises which have not dared to claim their own electric cars have been sold consumers. Even called off the “electric vehicle” panic buying boom BYD, also failed to provide a truly private consumers.

This situation is undoubtedly embarrassing, is like an actor on the stage singing, over and over we did not applaud a man, face still full of questions and see the eyes of an estimated capacity of nearly if the actor, even the hearts of all suicide the.

So, how can it break the deadlock?

Recently, some car enterprise business model proposed change came from the realization of “electric vehicle” breakthrough.

This business model has been most of the manufacturers mentioned is the “naked car sales, the battery lease” model.

Means that consumers can spend less money and the traditional car from the four S store to buy a “bare-car”, then go to a professional charging stations pay a certain amount of rental, you can receive the battery, electricity used up to the battery charging station replace the battery can.

The idea seems to be “perfect” or even appear to completely solve the electric vehicle development process bottlenecks – Battery problems: high cost of batteries, battery cycle life is too short, and so are charging is not convenient resolved.

In this beautiful “picture” of encouragement, we seem to be heading for electric cars soon, “Utopia”, a bright future in sight.

But in fact, this bright future is still “fancies”, are still only a “perfect” scenario, even to replace the battery, there are still many problems solved.

First of all, Who sets the standard battery? Unified standard mobile phone battery has been talk for many years, but there are still “smoke and mirrors”, as a new phenomenon, the standard battery electric vehicles they need for the birth of many centuries?

If the battery does not develop standards, the establishment of enterprises by a single car to match his car battery replacement stations, which only looks beautiful, and industry experts point out, fast rechargeable batteries for Friends of the scale of power plant At least it should be to 15000 1000 more than possible to achieve profitable enterprises a single car in a city order to achieve 15,000 electric car sales planning, may still be a long process.

Therefore, it is impossible to change the business model of Noah’s Ark electric car, at most, could only be a booster.

To really make the public accept the new energy vehicles, the key still have to have core technology, why Apple would make a sensational come on, let Apple fans queuing Goumai do day and night, why the public transit fare increase Xiaoshoujinguan Shoudaohenduo Guan criticism, but sales are still soaring? Why subsidize electric cars are still idle 60000?

Ultimately, though thousands of electric vehicles is now a favorite line, because he was an “ugly duckling” because of his lack of heart technology, even though his future is doomed only to “white swan”, but this is ultimately a matter for tomorrow, would like to Like the ugly duckling when the White Swan married, even subsidizing 60,000, consumers will not pay, because he is white swans, not ugly duckling.

Therefore, the electric vehicle order to usher in its spring, it is imperative that control of their own core technology, the early completion of its transformation and becoming a real white swan. Not play tricks, gimmicks, the new energy vehicles as entertainment events to hype, only to draw the eye and the layout, just to raise the so-called “enterprise” gold content, only in response to “the party and the government’s call,” this practice can only be sent to ruin the new energy vehicles.

Noah’s Ark of electric vehicles can only be a core technology to mature.
