Electric cars become the main direction of new energy sources, the three problems need to be solved

without comments

BYD F3DM launch the fastest dual mode electric vehicles present, except for a very small trial batches in Shenzhen, the market is still difficult to find their mark. There are various indications that the new Energy Line racing car technology, electric vehicles, China has become the new energy vehicle development, the main direction.

 

Electric vehicles in emerging strategic industries

 

Last Tuesday, workers issued by the Ministry of the fifth letter of energy conservation and new projects to demonstrate energy vehicles to promote the use of the VGP-BPS10 repertoire list of recommended models. In the list directory recommended, Sunwin Shanghai, Jiangsu, often long and Liuzhou Wuling three cases of three electric vehicles, so impressive.

 

In fact, since the first catalog of first car lots issued 193 energy saving projects and new demonstration vehicle to promote the energy use of models has been recommended to date, the Ministry of the letter published in five batches 46, all kinds of new energy vehicles, electric vehicles accounted for 28 models, not only more than all other technologies combined routes of new energy vehicles, but manufacturers are involved in Dongfeng, Chang’an, Chery BYD, Hafei, almost 20.

 

In addition, electric vehicles, and more recently “promoted” as a “new energy, energy saving environmental protection, electric cars, new materials, new medicines, bio-farming and industries of the information, “the seven new strategic industries” Seven “and one, all types of sufficient showing that countries have electric cars rather than VGP-BPS9/S technical in line with other new energy vehicles, like the future of strategic industries the country.

 

Previously, over a month, U.S. President Barack Obama during his visit, the electric car is also included in the release of the two heads of state signed the “Sino-US Joint Statement.”

 

The manufacturers of electric cars boom lifting force Qi

 

Policies to promote electric cars face a “wind” blowing hit, but at the enterprise level, electric cars feeding fat, “Thunder disaster” also rings frequently.

 

Last Thursday, the Shanghai Automotive and the United States A 123 Systems Inc. jointly announced that both sides of the shares in accordance with 51:49 ratio, the establishment of Shanghai Czech Republic, New Power Battery Systems Co. , Ltd. to jointly develop, manufacture and sale system vehicle battery power. As battery technology lithium iron phosphate in a corporation listed on NASDAQ in the foreground, A 123 now has a world-renowned large scale lithium-ion battery systems and batteries capacity. The industry generally believe that Shanghai Automotive and the A 123 of the cooperation will help achieve a new energy vehicles, Shanghai Automotive Industry Development Strategy and the key components in the battery system on the industrial development of the formation of ‘breakthrough.

 

At the same time, the reporter learned Hafei Motor, the company produced high-speed electric cars has been Saibao “Zheng Zhunsheng ‘official entry into the national high-speed production of electric vehicles directory. Hafei vehicle related sources, which can be vehicles of industrial production will soon be the first to enter the scope of government procurement in China.

 

In addition, the annual production capacity of pure electric vehicles in the 10000 Air Car power project was installed in Zhengzhou Institute of Aeronautical port. The project with Anhui, Chongqing, Henan, Guizhou and other places a number of car manufacturers have signed a long term cooperation agreement framework, and on this basis, the domestic VGP-BPS9A/B automakers and large-scale cooperation production of pure electric vehicles, a project is completed in 2012, the project can produce a pure electric car 10000.

 

Combining the previous mode double F3D M BYD E6 Electric Car, electric cars Chery S18, Beiqi “Beijing” BE701 mark Pure electric cars coming and Shanghai Automotive buses and electric cars, electric vehicles off the Unit, has been a marked increase in coverage other technical line of new energy vehicles. Fearing that the plane manufacturers in the optical current electric vehicles in terms of production and sales, the future of new energy vehicles will account for more than half.

 

Electric Vehicles Take-Sheung sandaokan “off”

 

However, despite the heat wave of electric vehicles, but the country does not dare to promise a company at a given time, will definitely launch its own electric vehicles. F3D M BYD dual-mode electric vehicles, announced the end of this year on the market, but outside of a very small trial batches in Shenzhen, the market is difficult to find the trail; Chery S18 also complained of be available this year, but understanding, the car during the year’s announcement was completely “Moxi”! Chery and Changan Electric Vehicle R & D-related person said that currently limit the development of the domestic electric car, there are three main factors: one is produced electric vehicle itself, one is its cost, it is one is its use of infrastructure.

 

It is understood that the basic technology of electric vehicles include four, namely, sony VGP-BPS2 battery technology, motor and control technology, vehicle technology and techniques of electrical energy management. In China, despite BYD, SAIC, Chery, Chang’an and so a few years ago began research on electric vehicles and development, and each has made great progress in the fields. However, the current situation, several major companies developing electric cars are still in some respects, there are advantages but there are other aspects of the situation in the short board. BYD battery technologies as well, but the technology of electric vehicles, but not obvious, Shanghai motor vehicle technology and energy management, it has been more advantages, but its battery for another great challenge.

 

The cost of electric vehicles from the point of view, as the generation of new products, its sales volume after industrialization can not be expected, many manufacturers have expressed their stakeholders, the market for electric cars for at least same platform as the price of traditional gasoline engine of the car 50% higher over. In fact, BYD F3D M nearly 15 million market value point of view, the least expensive compared to F3, a full price of more than 9 million yuan, this situation will undoubtedly limit the speed of vehicles electric market. In China, despite Chongqing, Shanghai, Shenzhen, Guangzhou and Hangzhou and other cities have increased to subsidize the use of new energy vehicles, but the VGP-BPS9A specific pairs of electric vehicles on how the subsidies are not an explicit statement to date.

 

Infrastructure for the use of electric vehicles is another cost. Based on the characteristics of electric vehicles, how to ensure the load quickly and easily to maintain the range of travel of electric vehicles, electric vehicles will obviously become a limiting factor in the development of a key. Now, look you require vehicle electrical training environments has a perfect network of charging stations, automakers and utilities rely solely on efforts are clearly inadequate. Even if he had confidence in the future for electric cars Nissan CEO Luo Card If Geen also pointed out that “electric cars have a bright future, but if the government does not join the perfect electric car charging stations, such as ranks of the construction of electricity infrastructure Automotive future will be more trouble!

Analysis of lithium-ion battery protection circuit principles

without comments

With technological progress and social development, such as mobile phones, laptops, MP3 players, PDAs, handheld game consoles, digital cameras and other portable devices has become increasingly popular, there are many of these products is used in lithium-ion battery-powered, while Because the characteristics of lithium-ion batteries and other rechargeable batteries may be different, usually with an internal circuit, many people do not understand the role of the circuit this article will be the characteristics of lithium-ion Laptop battery and its protection circuit works to develop.

 

Li-ion battery is divided into two types of primary batteries and secondary batteries in some of the lowest power consumption in portable electronic products used primarily in a non-rechargeable lithium batteries, while in laptops, phones phones, PDAs, digital cameras and so on greater energy consumption electronic products use rechargeable secondary batteries, ie lithium-ion battery.

 

And nickel-cadmium and nickel-metal hydride battery compared to lithium-ion batteries have the following advantages:

1, high voltage, single-cell lithium battery voltage to 3.6V Ion, far higher than the nickel-cadmium and nickel-hydride battery voltage of 1.2V metal.

2 volume density, the density of its capacity Ni-MH batteries or nickel-cadmium batteries 1.5-2.5 times.

3, retention of load (eg, a small self-discharge) in place well after the loss of his ability is low.

4, long life, use the normal cycle of life can reach more than 500 times.

5, no memory effect, charging the former did not short-circuiting the remaining capacity, easy to use.

As the chemical properties of lithium-ion IBM ThinkPad R52 battery, under normal use, its internal energy and chemical energy conversion between the positive reaction of chemicals, but in certain circumstances, such as its overload, over discharge and over-current lead to the battery Internal chemical side-reactions, side effects increase, it will seriously affect battery performance and life, and may generate a large number of gas, so that the pressure increases the internal battery soon after the explosion that led to security problems, then all lithium-ion batteries need a protection circuit, used for charging the battery and the condition of the discharge of effective control and under certain conditions, off-line loading and unloading to prevent damage to the battery.

 

The next picture shows a typical lithium-ion battery diagram circuit protection.

 

As indicated above, the road safety cage with two MOSFET (V1, V2) and a control IC (N1) and a number of RC element composition. Control IC is responsible for monitoring the Dell Latitude D830 battery voltage and current loop, and control two MOSFET’s Gate MOSFET switches in the circuit play a role in, respectively, to control the charging circuit and discharge circuit turn on and turn -off, the capacitor C3 for delay, the circuit on the load protection, over-discharge protection, over current protection and short circuit the function of protection, its work principle is as follows:

 

1, the normal state

In normal circuit N1 of the state “CO” and “no” feet high output voltage, two MOSFETs are in a state of conduction, the battery can be free to load and unload, because of MOSFET on - resistance is very low, generally smaller than 30 cents in Europe, so the resistance has little effect on circuit performance.

The protection circuit of the State microA level of current consumption, typically less than 7μA.

 

2, over-charging protection

Requirements of the lithium-ion battery charging method of the constant voltage constant current /, in the initial presentation, a constant current charging and the charging process, increase the voltage to 4.2 V (based on different cathode materials, and some batteries require constant voltage value of 4.1V) for a constant voltage until the current is smaller and smaller.

 

The battery is charging if the charger circuit out of control, will continue after the battery voltage exceeds 4.2 V constant charging current, the battery voltage will continue to increase at this time, when the battery voltage is charged more than 4.3V, the battery chemistry of the side effects will be aggravated and may lead to cell damage or safety problems.

 

In the battery with a protection circuit when the control IC to detect the battery voltage reaches 4.28V (This value for the control IC has decided that a different IC have different values), the “CO” PIN will high voltage variation is zero voltage V2 to the end of his tour on foot, thereby reducing off the charging circuit, so that the battery charger can not charge, played overload protection. V2 comes at a time due to the presence of the diode VD2 body, the hp F4812A battery can discharge the diode external loads.

In the control IC to detect the battery voltage exceeds 4.28V to return the signal between the V2, there is a time delay, the length of delay time is determined by C3, usually set at 1 second or two, to avoid interference caused by false judgments.

 

3, over-discharge protection

The process of discharging the battery on the external load, its voltage will be gradually reduced as the discharge process when the battery voltage to 2.5 V, its capacity has been completely shine, this time the load if the battery continues to discharge, the battery lead to permanent damage.

 

The process of discharging the battery when the control IC to detect the battery voltage drops below 2.3V (the value used by the control IC, IC have various different values), the “DO” PIN will be strong voltage variation is zero voltage, so that V1 amended by the turn-off, reducing outside the discharge circuit so that the battery can no longer discharged into the charges, has been over-discharge protection. V1 comes at a time due to the presence of the body diode VD1, charger through the diode can be charging the battery.

 

Due to over-discharge protection of a state of the sony VGP-BPS2 battery voltage can be reduced, which requires the consumption of the circuit current protection is very weak now control IC enters a low power state, all of the Consumer Protection power circuit is less than 0.1μA.

In the control IC to detect the battery voltage is below 2.3V to send off the signal between the V1, but there is also a time delay, the length of delay time is determined by C3, generally set at 100 milliseconds, to avoid interference from True or False.

 

4, over-current protection

As the chemical properties of lithium-ion battery, the battery manufacturer provides its maximum discharge current should not exceed 2C (C = Battery capacity / hour) when the battery discharge current of more than 2C would cause permanent damage to the battery or the safety problem.

 

Charge the toshiba PA3191U-3BRS battery in the normal discharge process, the discharge current after a series of two MOSFETs, due to MOSFET on resistance, will produce a voltage at its ends, the voltage U = I * 2 * RDS RDS for single MOSFET on resistance, the IC control over the “V” pin of the voltage value for testing, where the load causes an exception for some reason, so that increases in current loop when the loop current is so large that U> 0.1V (the value of the control IC has decided that a different IC have different values), the “DO” PIN will be significant variation in voltage is a zero voltage, so that V1 disabled by the turn-on, cutting off the discharge circuit so that the loop current to zero, to play on-current protection.

In the control IC to detect over-current shutdown has to make between the signals V1, but there is also a time delay, the length of delay time is determined by C3, typically 13 milliseconds to avoid interference caused by false judgments.

In the process of control over, we can see that the value of the size of its over-current detection depends not only on CI control control value, but also depends on the MOSFET on resistance when the MOSFET on resistance, where most of the same control IC, the over-protection during the most value.

 

5, short-circuit protection

The process of discharging the apple A1079 battery to the load, if the loop is so large that U> 0.9 V (the value is determined by the control IC, IC have various different values), the control IC is considered that the load short-circuit the “DO” feet are rapidly changing the high voltage to zero voltage, so that V1 disabled by the turn-on, cutting and discharge circuit, playing short circuit protection. Short-circuit protection, a very short time period, usually less than 7 microseconds. ’s how it works with the methods of over-current protection is similar, but different in determining the length of time protection is not the same.

 

More detailed single-cell lithium battery operates ion protection circuit, multiple-series Lithium-principle of ion battery protection Similarly, will not go above the control circuits used in integrated circuits Series Ricoh R5421 Japan, in the circuit the battery real protection, there are many other types of control IC, such as S-8241 Seiko Japan Series, Japan Series MM3061 MITSUMI, the Taiwan-rich and crystal FS312 series FS313, the Taiwan AAT8632 series of analog technology, and so on, his works very much the same, but some differences in specific settings, some IC controls to safeguard the external circuit, the capacitor filter and the delay of chip capacitors to achieve its peripheral circuits can be very small, like Japan Seiko S-8241 series.

 

In addition to controlling IC circuit there is an important component, is the MOSFET, it acts as a switch in the circuit, because cascade directly between the VGP-BPS9/B battery and the external load, so it’s on the strength of the performance of cells are the impact of MOSFET with a choice of better quality, on-resistance is low, the internal resistance of the battery is low, with a transport capacity is also strong in the exercise of their electricity consumption is also less.

 

With the development of technology, portable devices get smaller and smaller, and as this trend of lithium-ion battery needs protection circuit size are becoming smaller in the last two years have seen the day in the control IC and MOSFET integrated protection of integrated circuit products, such as the series DA7112 dialog, and some manufacturers even the whole package of circuit protection in a small size of the IC, such as product MITSUMI company.

Risk analysis of thin-film solar batteries

without comments

1, high-profit event

 

U.S. First Solar’s gross margins above 50%, but such a high gross margin because the company has a core of cadmium telluride thin film technology and its equipment are mostly self-designed, proprietary technology, so their cost than most solar companies is much lower. From the breakdown of costs can be verified that, although First Solar equipment depreciation for 5 years, compared with the other producers have AMAT Applied Materials, Inc. 7 years shorter, but still higher than the depreciation expense of the unity of the amorphous silicon plant AMAT more than 20% lower than the AMAT of the laminated product is 40% or more. First Solar thin-film producers all over the world, a good benchmark, but it’s amazing the goal is not easily available, and the general activities des

 

2, technical risk concerns

 

Due to rapid technological progress, the average price of polysilicon components from the current level of $ 4 / W by 2012, two U.S. dollars / W; thin-film batteries from the current $ 2 / W to $ 1 / W, the thin-film makes solar production capacity could reach 20% of the total solar energy, is now only 7.6%. Thin-film solar sony VGP-BPS2A battery technology must be improved, for example, need to improve the existing microcrystalline silicon coating because the thickness of the microcrystalline silicon solar impact performance. Thin-film solar batteries to do is thin, the conversion rate to improve a significant reduction in thickness to reduce production costs and other metrics. Most of the province of silicon thin-film battery is using a special process that continued gas with silicon deposited on glass carriers can form a layer of paved with nano-scale particles of silicon film as a piece of glass, with an area of up to 1 square meter, or even a few square meters. The thin-film solar batteries in the same size on the weaker power generation capacity than conventional batteries, photoelectric efficiency of only about 6%. Chinese Academy of Sciences Guangzhou Institute of Energy, according to recent forecasts by the year 2015 this number will increase due to technical advances by 12% to 16%. The world’s most advanced ion-beam deposition of nano-crystalline silicon thin-film technology, China is still empty. Crystalline silicon batteries with very different production technology is widely in manufacturing thin-film battery, like the semiconductor industry, such as vacuum coating technology, key technology have used this level of mastery and advanced directly to the volume of products affected income, indirect impact on the profitability of the company. Thin-film battery industry is a technological innovation on the rapid development of industry is based has been built is to explore one of the best process route too, so the need for continued improvement from the technology point of view thin-film sony VGP-BPS2 battery factory, manufacturers of crystalline silicon solar batteries are producing more need for a strong R & D and technical team. From a technical originality, digest and absorb and re-raise three are usually standards, Chinese companies are only in the most important independent intellectual property rights of long term in a weak position. If you can not catch up, then the thin-film solar batteries has continued to migrate to the “Introduction, backwards, then the introduction of” passive follow the trend of the old road, not in a position to the chain from production to sales of high End-to-fill.

 

3, equipment and raw materials short board

 

Thin-film battery technology development is shorter forms, no common technology and common equipment, the latest large-format thin-film VGP-BPS9/S battery devices offers a turnkey project is primarily the United States, Applied Materials (AMAT), Switzerland, Oerlikon and Japan’s ULVAC 3rd Equipment depreciation is one of the major costs of thin-film batteries, according to the current stock market listing, with the capacity of the battery production line of thin-film silicon prices are 6-10 times, including glass (glass and other conductive glass), EVA, Target and Gas and other important raw material supply, the current international giants are monopolies, high prices and no supply. ITO thin-film batteries require a higher current strength of weak domestic manufacturers, the market especially from Japan, NSG and the U.S. AFG partition. With the outbreak of the domestic production of thin-film batteries to supply most likely the result of the main raw material. Target current domestic supply, which is dominated by large international companies, Heraeus, Germany is the world’s largest supplier on the domestic market share of more than 6 in. Moreover, there is no domestic production of silane, but mainly large international companies with limited expansion opportunities as demand for LCD and other high silane is coupled partial delivery is still in short supply, prices continue to rise to maintain a high level does not exclude the possibility silicon thin films face Queliao risk. In addition, the thin-film cadmium telluride (CdTe) materials, there are still concerns about the toxicity, environmental protection and recovery mechanisms, tellurium supply mechanism hidden dangers, copper-indium-selenium (CTS CIGS) materials, it is the question of indium prices.

 

4, the market risk

 

Everything that is divided into two halves, and look at problems of the market, there must be an objective analysis of dialectical materialism. The great development of the photovoltaic industry, leading to rising prices of key raw material silicon, and finally forced to alternatives to the downstream business, believe it promoted the rapid development of thin-film technology on a very large number of companies find that they have a Starfall, crystalline silicon solar technology found pregnancy dive with a great breakthrough in the pricing on the eve of a sharp. This result is still at the level of the small thin-film Dell Inspiron 8500 battery market and the strong momentum of development will be the impact of changes in market investors form must be fully understood, otherwise errors can occur.

 

5, risks of investing in

 

Currently, Chinese companies have much in the introduction of foreign monopoly, invested thin film solar battery production lines. Three giants of the world, one of the United States, Applied Materials, Inc. amorphous silicon thin film solar modules to produce a series of automatic production line, for instance, to project a total investment of 14 billion yuan, annual production of amorphous silicon thin film solar batteries 500MW, with an annual turnover of 20 billion yuan. Investment intensity per megawatt of production capacity by 2800 or 28 million yuan RMB per watt, a turnover of 40 million yuan to invest grid / MW, or 40 yuan / W. This easy-to tens of billions of investment risk should be carefully examined. Switzerland and Europe Likang automatic production line of thin-film hp PP2182L battery prices of imports of 100 million yuan dollar, combined 700 million yuan. In addition, the production process is environmental issues will consume a large amount of investment in environmental protection department or face opposition.

 

6, financial difficulties

 

Solar PV industry is a money-burning industries, the financing capability of a large company test. But the most dangerous place, but also risky places, is from a philosophical standpoint, the greater the risk, the greater the chances. In other words, there is no opportunity without risk. The wind is now that my votes. With minimal investment to earn the greatest profit, is the eternal view venture capitalists, but also the strategic goal of the philosopher, the two differ only pure venture capitalists will benefit as a goal. Investors on the financing side of the evaluation criteria are mainly two first the profitability of enterprises, followed by the scale. In addition, enterprise system, corporate culture, team composition, executives and others have an assessment. Standing at a higher level view of these questions, we will have time to go see the industry that has little relationship, because the key to see the VGP-BPS10 results. First come, the current environment, then there are other problems can not be generalized.

 

Our answers:

 

1. R & D and commercialization of solar PV companies should also focus on understanding the two. Accurate select the entry point to participate partially in control of the situation with the strategy, both in accordance with national conditions, also in line with the best economic option because the lowest price to produce the best results are always the best choice for investment. “Power wins very brave man to win power disparity wise man.” Achieve control of the situation, do so by local targets, the need for more intelligence to this, because it requires a global vision of a comprehensive strategy, intelligence and strategic courage. People who can not fearful strategy for winning the top spot because it is often the most dangerous, but also the balance of power in force. Big bet on solar PV by the “technology innovation and lower costs” that two keys so that the cost of solar power for the next generation of 0.5 yuan per kWh on the price and VGP-BPS9/B thermal energy equivalent to a strong competitive advantage to connect on the market to the premise of the initiative to regulate the use of large scale, when promoting the market demand burst like a blow-out type, solar batteries on board from the current use of additional alternative energy peak.

 

2. Although the same time, faced with a shortage of materials, technology development, leading talent and its own challenges, such as intellectual property rights very short, but we are committed to their own multi-level research and development team, construct addition, it should with Applied Materials to work as the United States, Japan, ULVAC, Switzerland, Oerlikon thin-film battery technology world, such as monopoly giants technology alliance, which is a good strategic decision.

 

3. Japan’s Sharp Corporation developed a prototype solar batteries on gallium arsenide ingots, has its photoelectric conversion rate reached 25-28.5%, according to the story of Sharp, an energy efficiency approaching 30% can have a prototype product, when the actual efficiency of production is very up to 20%. Who is the first to master the advanced technology, who reflects the lead in industrialization, the first to the photovoltaic industry, “high growth, high investment, high output” properties.

 

4. Production of photovoltaic power in China today is not simply the application of power, short-term needs the support of the international market, but the long-term strategic perspective, the domestic market is a strong resource can not be ignored. Together with the opening of the domestic solar PV market approaching footsteps, “staking their claims,” floating on the operation of the tactical turn table. Need as quickly as possible sunshine intensity of the former government signed a joint construction of three solar power plant demonstration project cooperation agreements for the construction and application of solar energy, local governments, or if the BATBL50L6 technologies and products ready to promote the market have been divided since a long time.

Lithium industry: a sunrise problematic industry

without comments

Influx of a large number of companies, but it is followed by a rapid decline in profit margins, current earnings are relatively modest. “According to one press access to information shows that in a few years, the profits of the sector before 100% of profits fell to 5% of profits are low.

 

Moss is the beginning of

 

“In Shenzhen alone, there are hundreds of production companies, all countries should be more than 1000 of the”. Zhi-Ming Zeng said “China’s Sankei Shimbun reporter, although the development of the industry supply lithium just a few years, but the pace of development beyond imagination.

 

Zhi-Ming Zeng worked in Beijing, Anwar Ibrahim on United Energy Technology Co., Ltd., has been witness to this emerging industry since its Laptop battery birth, then quickly dissolved into chaos after the development of the whole process.

 

Beijing Anwar United Energy Technology Co., Ltd in the industry is also a relatively big businesses and claimed to be the best technology for domestic iron phosphate factories producing batteries, the main development, manufacture and marketing of new batteries power rechargeable lithium iron, lithium-ion rechargeable battery and its subsidiary products are widely used in electric vehicles (EB / EV / HEV / PHEV), electric tools, solar, UPS, digital products, products of export to Europe and North America.

 

 

Currently, however, Beijing Hualian contract security industry, like the vast majority of companies is in the common development of the industry to feel the pain of confusion.

 

If Sony in 1992, the company will sell lithium batteries as a starting point for the dates industry. Then, set up by thousands of businesses, there is a sizeable proportion of companies are neck and only 50 million fund has committed more than 10 employees, renting office space, and even BTP-43D1 some minimum level of production equipment has not yet completed its acquisition of haste.

 

“These companies are not standardized operations, directly leads to lower margins on products, currently only a small number of large enterprise customers end because of stability and healthy development.” Zeng Zhi-Ming laments.

 

“2007 years ago, few people realize that the lithium iron phosphate promising, but production of lithium iron phosphate over 100 companies.” Xu Gang, vice-president of Tianjin power of God in the media about the fierce competition in the sector said. “The real business is doing quite well very soon.”

 

Technology Highway

 

According to the industrial chain, the lithium in batteries and produces batteries, Dell Latitude X1 battery materials can be divided into cathode materials, anode materials, membranes and electrolytes. Lithium cobalt oxide, manganese oxide, lithium nickel cobalt manganese-lithium and lithium iron phosphate cathode material for Li-Ion battery technology, the basic material Zeyi graphite anode, solid particles of carbon-based; in positive and negative electrolyte East and diaphragm.

 

The status quo is both manufacturers of lithium battery materials and battery manufacturer, has technical advantages of firms are very small.

 

“The main problem the industry is not competitive and disorder problems, the most critical issue is the price and technology.” Institutional research Frost & Sullivan focused on energy sector analyst Linda again told ” China’s Sankei Shimbun “Report to the United States, Japan and other countries, the Chinese Li-ion hp Pavilion dv4 battery industry, the technology gap is evident.

 

It is understood that companies worldwide have also strengthened their research and application of lithium batteries, but lithium batteries and other current high explosive which remain outstanding and Chinese manufacturers in the most backward in this regard.

 

BYD is a relatively rapid development of industry and enterprises in technology also have the advantage over their peers. BYD propaganda techniques, but actually did not get all the benefits of peer recognition, Zhi-Ming Zeng on BYD lithium battery that is not new, and the United States similar to products similar.

 

Li-ion battery industry has been concerned about the development of wind investment industry, Chen Qiudong also noted the technical level of the industry problem of the poor.

 

Chenqiu Dong said the domestic iron phosphate lithium material is not a company analysis, each doing a half-dozen properties of materials are needed for the overall level is not difficult, but to do this material (in particular, is to watch the processing performance, stability, and discharge broadband sexual characteristics) is not easy.

 

Statistics show that China, Tianjin, Shandong, Zhejiang, China (Jiaxing, Huzhou, Jinhua) and other places enormous investment of many to the sony VGP-BPS2 battery manufacturer Li-ion batteries, the results will die of ‘a natural death, the main technical issues can be resolved. Chenqiu Dong said that with technology partners to find a great association. Many colleges and universities or research institutes, technology is just technology laboratory, far from industrial. Laboratories doing material properties are excellent, but the pilot will encounter great difficulty, even if reluctantly passed the test pass, the stage of mass production industrial, exposing the problem will be even greater . And this is not an isolated phenomenon, but rather a common phenomenon.

 

Linda noted that in addition to technology, the price of lithium high power hamper its rapid implementation is a key factor.

 

For example, a lithium-ion battery electric bike for the price of 1,500 yuan, while the current total price is also an electric bike, but about 2,000 yuan, if electric cars are being lead to the most-assembly acid batteries.

 

“The main reason is the high cost of production is low, there is no scale. If we can balance the production, sale, these costs should be quickly abandoned.”

 

Achieve the same high prices of the deepest reason is still an immature technology, resulting in the production and marketing limits.

 

CITIC Guoan (15.44, 0.25, 1.65%) Mengguli Power Supply Technology Co., Ltd. in Beijing during the Olympics for the 50 pure electric buses in operation provides the necessary batteries, and its technology in the industry considered relatively mature, and even well, its Lu, general manager of its admitted, “synthesis technology of lithium is still a problem.” The stability, consistency of production and life of the technology of lithium batteries is not yet mature.

 

Warlords battle for the throne

 

Warlords battle for the throne, such companies will win?

 

In short, technology is king.

 

On the most critical factor in business development, Zhi-Ming Zeng said the two words “innovation”. He was referring to technological innovation.

 

Linda noted that the company will finally, it must be to solve the problem of toshiba PA3191U-4BRS battery price and technical aspects of the business.

 

Technology, Chen Qiudong consider more comprehensive, he summarized the following three elements: mature technology, a strong management team and excellent resources.

 

Chenqiu Dong said that the three are complementary, we can not do without. There are no mature technology inevitably limit the speed of development, so stay in laboratory techniques, or at least have been at least 2-3 years of exploration, technology and talent are also inseparable After all, the lithium iron phosphate material technology and is not fully mature, the industry has no uniform standard, equipment, materials, processes, and so the real questions should be able to count on people to solve. Without a strong financial strength, even if the materials out of, the corresponding production or management can not keep, they lose opportunities for collaboration with key customers, key technical staff for motivating the team enough, lead loss of human resources. Have no outstanding management team, even the best technology does not produce value here includes the implementation of the said R & D, production management, quality management, marketing and other links for startup companies that are very difficult.

 

However, the company won the healthy development of the apple A1061 battery industry as a whole can not be separated. As CITIC Guoan Mengguli Power Supply Technology Co., Ltd., General Manager of the Lu said: “I am most concerned about is when they can regulate this industry together.”

The status and development trend of Lead-acid battery industry (part 2)

without comments

Thirdly, key initiatives aimed at solving environmental problems is the full implementation of the policy of recycling batteries

 

China is actively pursuing the circular economy, waste batteries can be recycled to 90%, but the industrial policy of China does not waste battery recycling a good development space, resulted in their becoming long-term problem bottleneck in the development of China Battery. China is not a lead-acid battery management of waste recycling, legal standards, the country was not prepared to conduct business waste professionals acid battery recycling, not a business or professional secondary battery recycling lead companies to establish a national network and a network of regional collection, recovery of all the work is the decentralized management state of unrest, the recovery rate of waste lead-acid batteries n ‘ is not high. Problems recovery of lead in non-standard commercial rehabilitation and strengthening of management is imperative, the state departments concerned should the policy as soon as possible, as the ban small coal mines, small smelt, as after a waste recycling lead small businesses. At the same time put in place policies to encourage and support large-scale manufacturers of Dell Inspiron 5150 battery recycling used batteries. Limiting the development of secondary industry to lead China are main factors: first, the cost burden of environmental protection equipment. Companies with advanced technology, the protection of the environment and well equipped to benefit the company not modify the technological backwardness of the serious pollution of the city “lead smelting small.” Second, surveillance is not enough. None business license is also under secondary lead production, correction palliative, were closed for “low melting lead, the wind is over, the resurgence. Thirdly, industrial policy is not conducive to business informal. Tax too heavy also undermined an advance regenerated large enterprises to increase the capacity of environmental governance. 

 

Fourth, the development trend of China’s lead-acid battery industry

 

Discharge is more than one hundred years old lead-acid batteries due to low cost materials, simple technology, the technology is mature, self is low, maintenance free characteristics of needs in the decades to come, still dominant in the market although the starter used, the power market space battery in May will be a turning point in the near future the development of domestic industry will remain dominant in the medium term will also be a place in the long term without is necessary to use high weight ratio of energy continue to exist. Currently, its major application areas of origin such as motorcycle motor, power supply parts, etc. in the substantial growth, but also in new application areas such as electric bicycles, buses can be used such as the development of valve-regulated development of hp Pavilion DV1000 battery technology to meet the high technology, such as UPS, power and communications equipment, food needs. As the lead acid battery technology continues to advance, making the electric bike industry, tremendous development, and to fuel cars and fuel to reduce pollution from motorcycles to make a contribution. Maintenance free technique, drawing technology in the grid net for the rapid development of the automotive industry. We can say in these applications in lead-acid battery technology advances to improve the competitiveness of the country has made real contributions.

 

Power tools, electric bicycles and other industries demand for small mobile battery industry has spurred the rapid growth momentum. Electric bicycle battery set most VRLA batteries after a performance improvement, energy and life cycle of a breakthrough, but so far remain in the high flow rate that energy is not quite high, deep-cycle life is not long enough gap largely affected the rapid growth of the electric bicycle industry.

 

Electric bicycle as a means of transport in less developed countries in recent years, rapid development, particularly in China. From 2000 to 290,000 in 2005 developing 12.09 million, the rate of average annual growth of 174%. It is expected that in the future for a long period of time, the batteries of electric bikes products will flourish. China’s Electric Power batteries bicycles used lead-acid batteries for more than 95%. 2006 Electric Bicycle sony VGP-BPS2 battery capacity of 40 to 50 billion by 2015, the output of electric vehicles in China will reach 1,000 billion yuan, including 16.0 billion supporting cells. The secondary market to replace the battery 480 billion, which is a huge market.

 

5, lead to China industrial battery acid, the direction of development envisaged

 

encourage bigger and stronger, improving the degree of industry concentration

 

To upgrade industry clustering effect, actively respond to various market risks, with equipment, manpower, technology, and effective integration, reduce waste, training of the optimization structural product additional columns for increased investment in efforts to protect the environment, an effective solution to pollution problems in the production process and further strengthen the leading companies in overall strength and realize the magnitude and Development group.

 

upward trend of lead acid batteries

 

To seize market to expand the size of the lead industry of toshiba PA3421U-1BRS battery acid, and strive for annual production of 2010 of approximately 131.75 million KVAh, sales income of 66 billion yuan.

 

be development-lead acid batteries

 

Although the lead acid battery technology continues, but the specific power, cycle life and other issues is always the emphasis on industry issues. Therefore, increased efforts in R & D efforts to improve the level of scientific research to enhance competitiveness are the only way for industrial development. Across the bridge and link between the role of the Association, and vigorously for businesses to create a platform for exchange and communication with the upper lead, partitions and other downstream industries, such as vehicles form an electrical and mechanical joint research and development, a group formed to unite foreign ALABC or a similar alliance to jointly research and development and strengthen R & D capability.

 

accelerate the adjustment of product structure, standardize the market recovery and regeneration

 

Increase the proportion of new products, develop sound and resource efficient products, focusing on the development of sealed maintenance-free lead-acid batteries, the phasing out of open-type batteries. Lead acid batteries to accelerate the technological transformation of enterprises, the use of process equipment for advanced and effective monitoring of the production process problems of environmental pollution, to achieve higher production clean. Encourage colloidal lead-acid batteries, winding type bipolar lead-acid batteries, and other new types of apple A1079 battery research and development, improve the use of more power and lead to regulate the market lead - Recovery of acid batteries and recycling, reducing waste lead-acid batteries of environmental pollution, noise oriented and resource management.

 

expand, standardize the export market to avoid trade frictions

 

A careful study of the international market demand, the range of export products appropriate adjustments to reduce the export price of competitive products, development of new applications and markets. Occupy the market share of low price, it exports the lead acid BATBL50L6 battery blow to China. At the same time, may be subject to foreign anti-dumping lawsuits, resulting in higher product has been imposed anti-dumping duties, loss of self-rising prices fair. Therefore, the Association should play in regulating the order of foreign trade and industrial development in the role of coordination to protect the legitimate rights and interests of enterprises, establish a standard order of competition to prevent abusive behavior cheap exports. Also studied the relevant policies of the country’s target market to consider establishing manufacturing bases abroad.
