Domestic and international power lithium-ion battery applications market overview

In recent years, power type lithium ion battery by the people’s attention, has been widely used in electric tools, power toy area, and in the EV (electric vehicle) / HEV (hybrid electric vehicles), electric canoe, electric bicycles and other areas of have potential application prospects.

Power lithium-ion battery’s current development status of

China’s lithium-ion battery research project has been issued a national “863″ key project, much of the material to achieve the localization and the introduction of multi-national has been self-built production lines and supporting materials, factories have more than one, have been the formation of large-scale production.

Power lithium-ion batteries currently in the industry in period.

Over the years, many developed countries overcome the electric vehicle as the main objective of the United States to support multiple national laboratories and companies will share in automotive lithium-ion battery development. The EU has developed a high specific energy battery development plans, using a means of plans and programs to ensure the continuity of basic research, and continue to produce the results phase. Japan in the field of lithium-ion battery has a monopoly, Sony, Sanyo Electric, Matsushita Battery, NEC and other famous companies have built large-scale lithium-ion battery manufacturing plant, but most manufacturers in addition to maintaining and expanding the production of the original brand, are in using their own advantages to develop lithium-ion battery of new products. Overall, Japan is still a power lithium-ion battery technology leading countries, its power lithium-ion battery and its key material production technology has matured to meet the electrical performance has almost

Moving vehicle demand.

More than 10 years, China’s lithium battery industry, from scratch, from small to large, rapid development, production capacity after Japan. China’s lithium-ion battery R & D project has been the national “863″ key project, much of the material to achieve the localization and the introduction of multi-national has been self-built production lines and supporting materials, factories have more than one, have been the formation of large-scale production, marketing fierce competition, mainly investment-driven industries.

Lithium-ion power battery products first used in electric bicycles, has been mass market. Car batteries, There are also a number of units of lithium-ion battery had been loading a demonstration run, but the overall level of commercialization are still away from the real distance from the single battery life and consistency, and Japanese products there are obvious gaps, battery management systems, and batteries

Group technical level we also need to increase the level of key materials and industrial capacity still need further improvement.

After years of research, national power lithium-ion battery development has made great progress, mainly iron phosphate cathode material lithium and lithium manganese oxide, in the capacity, safety, cycle life and other aspects have been fully able to meet the power equipment requested that the electric bicycles, hybrid-electric vehicles, pure electric vehicles, electric boats, UPS power supply and other energy storage

The device has already begun the application of high-volume applications, but will take some time, probably the last two years. Domestic and foreign enterprises have focused their attention forward to this big cake, and have invested in research and industrialization, and hope to get huge benefits in the future returns.

As electric vehicles, electric bicycles, electric tools, portable electric appliance components of the core energy power batteries about to develop into a key factor in the development of electric vehicles, therefore increase the battery and its related materials, research and development has a decisive significance.

The power battery in lithium-ion battery With light weight, small size, long life, the voltage high and no pollution, the “ultimate battery,” said to have attracted worldwide attention by the market, gradually replacing the nickel-metal hydride, nickel-cadmium and so the battery. From the lithium-ion battery cathode material point of view can be divided into the current lithium-ion battery: lithium cobalt oxide batteries, three

Yuan material batteries, lithium manganese batteries, and lithium iron phosphate batteries. Mobile phones, notebook computers, batteries are generally of lithium cobalt oxide batteries and ternary materials, APPLE IBOOK G4 12-INCH SERIES battery, this is because lithium cobalt oxide

And ternary materials, higher than the energy in a smaller size to store more energy inside, but it’s less secure, it applies only to a small battery. The manganese oxide of lithium and lithium iron phosphate, despite their lower than the energy, but the safety of a high, so are ideally suited for medium-capacity power battery, which is a more internationally recognized technology options. The large-capacity power battery large-scale application has yet to be fire-retardant electrolyte membrane high melting point, high stability, charge state of anode materials development.

As Lithium iron phosphate battery has a very high cycle performance, better safety performance, while its cost is far lower than that of lithium cobalt oxide, nickel, lithium and ternary materials, although much higher than the cost of its batteries lithium manganese oxide, but the If the volume of production is expected to fall, and a considerable level of lithium manganese oxide as lithium iron phosphate with iron, phosphorus as raw materials, their sources rich in low prices, because

This is expected in the next few years, large quantities used in the lithium-ion power batteries.

Power lithium-ion batteries currently in the industry in period. Battery-related technology is already mature and have their own characteristics, a number of standardized tests in progress, towards mass production. Battery pack and battery management system for related applications has not yet standardized, in the state of their own development.

Lithium-ion battery cell manufacturers involved in the development, application and market acceptance of and so on. In terms of the battery manufacturers now can produce power to meet the diverse needs of lithium-ion batteries, its applications include a variety of electric vehicles, electric tools. But its wider application also need to market acceptance, the current European and American companies have begun to purchase fixed

Li Li-ion batteries used in the field of electric tools and electric vehicles and domestic use are also in the initial stage. In Tianjin, the 8th China International Battery Technology Exchange Fair (CIBF2008) displayed on the number of companies that apply to vehicle start, power tools, electric bicycles, electric vehicles and hybrid electric vehicle power lithium-ion cells and batteries.

Power lithium-ion battery development has been a long time, the earliest studies used in power tools, electric bicycles, electric motorcycles, and now the main research in pure electric cars, hybrid cars and so on.

Market is expected in 2020, hybrid cars will account for 30% of the entire vehicle market share. China’s CITIC Guoan Mengguli as early as lithium manganese lithium-ion power battery used in electric buses on the Olympic Games. Jiangsu and Zhejiang area in 2006 to develop electric bicycles, electric motorcycles, electric cars and hybrid cars and so on.

A matching power batteries are also the rapid development of the study was first applied to the nickel-metal hydride electric vehicle batteries, because of its presence relatively low energy density and power density, life is short, with defects such as memory effect, it is difficult to develop rapidly.

Currently in the field of energy storage is the best lithium-ion battery energy density and power density, life expectancy of 10 years, no memory effect, light weight.

Currently there are a lot of power battery manufacturers to study the manufacturers for more have been put into operation a large number of stars Constant power 55 of Jiangsu pool, Wanxiang Group, Lei-day battery, CITIC Guoan Mengguli so. Lithium batteries have been able to fully meet the performance of pure electric vehicle and hybrid electric vehicle needs. Production of lithium-ion power tools, electric bicycles, electric motorcycles battery manufacturers even more numerous, including the Ye-Xiang Jing Branch, Huilong Science and Technology, Wuhan, a large number of companies such as Li Hing.

Become an obstacle to the development of secondary batteries of electric vehicles practical progress in the major bottleneck. At present, lithium-ion secondary battery because of the energy density, voltage, and no memory effect, and other areas has attracted researchers of all ages. LiMn2O4 (lithium manganese oxide) series material has abundant resources of raw materials, low cost, safety, good, no environmental pollution, the advantages of easy preparation, making lithium-ion batteries power the most promising cathode material.

Hinder the development of lithium-ion battery power bottleneck

At present lithium-ion battery development is limited so that the bottleneck is the cost.

Standardization of system applications are also constrained the development of lithium-ion battery power bottleneck. Based on the rapid development of China’s battery industry to develop a pure electric vehicle industry is to achieve leap-forward development of China’s automobile industry a major opportunity, power COMPAQ PRESARIO M2000 Battery industry has also ushered in unprecedented opportunities, at present, restricting the development of China’s motive power industry, mainly in some of the key factors that materials, manufacturing processes and equipment, etc., only research units, materials businesses, the battery company with joint research in order to achieve a breakthrough needs to co-ordinate arrangements, especially the common industrial technology, such as can form an effective joint research and technology transfer mechanism, is conducive to industry technical standards improved rapidly.

At present lithium-ion battery development is limited so that the bottleneck is the cost. Costs are two aspects, one is the cost of the battery itself, the other is a lithium battery electric vehicle charging facilities for the cost of supporting. To give a simple example, is equipped with an electric bike 36V, 10Ah lead-acid batteries, worth about 400, while the 36V, 10Ah lithium-ion battery power you need to spend about 1,200 yuan, a full three times the lead acid batteries, is particularly important yes, a lead-acid batteries for electric bicycle is equipped with only 1,800 yuan, while the same is equipped with lithium-ion battery electric bicycle will need 2,600 yuan, lithium-ion battery which accounted for 46%. In comparison, power lithium-ion batteries in hybrid and pure electric vehicles and other devices share the cost of the application of even greater because there are needs of supporting network of charging stations provide easy and convenient charging. Therefore, reducing the cost of a lithium-ion battery powered applications, the top priority, now available in the following ways to reduce costs:

First, the lithium-ion batteries to reduce the cost of key materials, in particular the cost of membrane and electrolyte, the current in the membrane and the electrolyte lithium hexafluorophosphate basically rely on imports, if the realization of localization can be significantly reduced manufacturing costs, currently has 23 domestic broke through the membrane manufacturing technology companies to start mass production, but can not completely replace the imported membrane.

Second, to extend power lithium-ion battery production scale, enhance the level of automation, lower costs, which needs funds a large number of intervention, require an additional battery charging station facilities supporting a large number of pre-investment to facilitate the application of electric vehicle environment.

Power lithium-ion battery industry is the main bottlenecks in the standardization of system applications. Industry needs to promote the power lithium battery industry from the start-up stage into the growth stage. China Power Supply Society and the Physical Chemistry bump technology to launch a “battery management system development and application of Union” will be the contact application of the battery industry and system vendors a link between different industries, in order to promote the electric

Pool management to contribute to industry standardization.

Alliance’s strategic objectives are: to use 2 years -3 years to develop into a green industry, battery industry influence Union; building to Chinese companies as a starting point, facing the world battery industry to world-class battery management technology platform, Industry Alliance; to help the battery industry organizations to develop uniform standards for electronic interface and institutions for the global power batteries contribute to the development industry.

Power lithium-ion battery development is a systematic project, subject to many factors, but also a number of factors constraining each other, with the impact of the development of lithium-ion battery power, such as the prices of raw materials directly affect the price of the battery, while the price of the battery has a direct affect the market recognition. In addition, consumer spending habits of the lithium-ion battery powered hair

Show the effects brought about can not be ignored. For these factors, on the one hand the need to further reduce the cost of production processes, raw materials, the production of the battery pack and battery manufacturing. Is a matter for the market requires a gradual process of awareness and maturity, is sometimes necessary to overcome some aspects of consumer habits.

Power lithium-ion battery development bottleneck lies in the improvement of energy density, safety, improved cost control three aspects. Increase in energy density and battery safety improvements with certain contradictions, it is necessary to find a balance between the two points, in ensuring security on the basis of constantly improve battery energy density cathode material through the system and the electrolyte

Continuous improvement to achieve our goals. Battery cost reduction bottleneck is the cost of imported materials such as high diaphragm, and the current price of copper and other metals have been rising, to reduce the cost of the battery caused certain difficulties, but with the Science and Technology and other government agencies membrane localization of continued support, coupled with automated battery production plant in the continuous improvement of the battery and battery material utilization pass rate rising, I believe that will continue to lower the cost of the battery.

Impetus to the development lithium-ion battery industry is also need materials and technology efforts:

Need to address the fast charge-discharge capacity fast enough.

Lithium-ion batteries need to address the flammable and explosive solvent electrolyte deficiencies.

Membrane localization of the battery as soon as possible.

Materials, anode materials and electrolyte are gradually formed the competitiveness of domestic enterprises, mainly upgrading of technical indicators, the localization of membrane is also implementation. Toshiba pa3166u-1brs laptop battery manufacturing process and equipment problems is relatively large. States should industrial policy, tariff policy, etc. to encourage independent innovation and introduction of digestion and absorption re-innovation. Intellectual property rights also need to combat

Co-ordinating strategies and strategy considerations, industry associations can play a more important role.

Power lithium-ion battery is still in the early stage of development, but also need to continue to improve the upgrading. Industry policy is most needed is the Government’s new energy industries continue to increase industrial development funding and investment support to the Government for tax policy, infrastructure supporting the industry and to promote investment between the aspects of support.

The current power battery batteries in mass production, after years of efforts, power tools, electric bicycles and electric vehicles, hybrid vehicles ready for use. With all the battery power battery manufacturer of large-scale production conditions for production line continues to mature, by the end of 2008, China’s power battery production will enter a new level. At present, the battery management system development is still weak links. Government investment in new energy technologies, in electric cars, electric bicycles in policy support, and even tax

Support, will promote the current industrial development.

The development of lithium-ion battery power by the impact of various links, first of all can not do without the support of the policy, a policy of active support and guidance to create a suitable environment for the development power lithium-ion battery industry will have a tremendous role in promoting, as appropriate The government subsidies will certainly stimulated by the rapid development of lithium-ion battery. Battery manufacturing sector from the point of view,

Technically no longer exists in the production of major obstacles, but the raw materials needed for production of the battery varies, such as the anode and cathode materials and hardware accessories available domestic production, process technology is gradually improving and perfecting; while battery separator is mainly dependent on import, production and R & D and thus need to actively study and explore the production process, so that localization of cell membrane as soon as possible.

Impetus to the development lithium-ion battery industry is mainly from the material and technical aspects of extensive research, to improve battery safety performance and energy density and power density, single battery to solve the issue of consistency. Power lithium-ion battery materials, lithium iron phosphate cathode material while lithium batteries for electric vehicles to meet the requirements, but there are still some shortcomings.

1. Need to address the fast charge-discharge capacity fast enough. Therefore, the need for lithium iron phosphate materials research, carried out nano-technology, to optimize the conductive agents, so that the battery be able to meet these requirements, Fortunately, battery and materials experts in this area has made a breakthrough.

2. The need to address lithium-ion battery electrolyte solvent system for flammable and explosive deficiencies. The current power lithium-ion battery electrolyte solvent system there are still shortcomings of flammable and explosive, since the use of lithium iron phosphate, and lithium manganese oxide cathode materials such as relatively safe, coupled with the use of flexible packaging or plastic packaging, so that the safety of the battery greatly increased. However, the availability of its own

Flammable still exists, is still a security risk. Therefore, it is targeted to study some flame-retardant additives or by using ionic liquid electrolyte can be flammable and explosive from the fundamental solution to the problem.

How clever to solve the problem of consistent single sony pcga-bp2t laptop battery is still the driving force for development lithium-ion battery industry direction, the study units in a lot of achievements are huge. Example Bump (O2) technology, power battery management system, power battery industry has achieved great success. But still need to continue efforts to make consistent use of the battery really.

The current policy on electric cars or hybrid cars more support is still very large, for power lithium-ion batteries support to the poor, and further support to the relevant materials industry is very weak.

The policy response to power lithium-ion battery anode and cathode materials, electrolyte and related flame retardants, ionic liquid, a new lithium-ion electrolytes and other industries to provide appropriate support. Especially for the electrolyte and the related flame retardants, ionic liquid, a new lithium-ion electrolyte research support is clearly insufficient. Some of the key quality of materials are obviously unable to meet the current R & D needs

Should be, let alone to meet the future demand.

Power lithium-ion battery in order to be faster and better development, material improvement is fundamental, cathode material, electrolyte, anode materials and new materials developed to match the post-electrode technique, the battery system for matching research has a lot of work to 完成. With the continuous improvement of materials technology, the battery’s performance will continue to increase.

Currently the mechanism in the material, and battery research worse than that of some foreign countries, especially the power battery and electric car such an emerging field, in many battery electric vehicle production process, or the problems in the application process can not find reasonable cause, the lack of perfect Detection and analysis of various ways to the battery can be the basis for the Government Analysis and Research

Give support; In addition, power lithium-ion battery production process of the plant humidity, cleanliness and others have strict requirements, so companies from start-up phase to full production is a very difficult process that requires the government be able to bank loans or similar to support the industrialization of enterprise projects; third, the electric vehicle industry, the development of a direct impact on power battery market prospects, hope that the Government vehicles in the new energy-related policies can give some support to promote this emerging field of The rapid development.

Lithium-ion battery as a power battery at the same time to consider the performance, safety, and price. Power lithium-ion battery industry matures, the development of membranes depends on the security and battery and lower prices.

Power lithium-ion battery development trends

Do more ruthless in reducing costs.

Once the grid with a strong tone of

Festival capacity, solar, wind, geothermal, ocean energy and other intermittent power generated by clean power generation into the grid is easy, clean energy will be large-scale application, which is faced by humanity’s energy and environmental issues will have a crucial role in .

Lithium-ion apple ma561 laptop battery industry in China is characterized by quantity, but the large scale, high levels of technology and equipment limited, with strong ability of independent innovation and even less, businesses need to strengthen the independent innovation capability, and actively participate in cooperative development, it is possible to achieve extraordinary development.

From a market perspective, electric bicycle is also a real existence in recent years the lithium-ion battery for major markets. The development of lithium-ion battery power there is still a long way to go, now just entering the field of electric bicycles, electric cars, electric boats, the application of energy storage devices also need to increase efforts to promote, with the national awareness of environmental protection enhanced Governments, particularly developed countries, the government advanced the application of lead-acid batteries may adopt a series of restrictions,

When the cost of lead-acid batteries and power lithium-ion battery, when the cost of convergence, power lithium-ion battery is bound to usher in the peak of its development, comprehensive alternative to lead-acid batteries as the main storage battery. China’s lithium-ion battery power enterprises should be actively speed up the rate of lithium-ion battery research and development, in itself to make an effort to reduce costs, while improving their own skills and capacity

Product quality level fight for a start ahead of the world, with international direct integration, accounting for a large enough market share. Power Li-ion battery will face a rapid development stage, depending on the current tight energy markets, environmental requirements, as well as the establishment of a new energy system. Thus, from the enterprise is concerned, should grasp this opportunity now, capture the market as soon as possible. At the same time, from the government is concerned, industry standards, and on this basis for the battery industry in policy co-ordination is also essential.

As the power lithium-ion batteries rely on the development of various businesses and industries, but is still in the early stage of development, and as the whole industry chain link, all businesses need to actively cope with clear development of the industry trends, accurate positioning, improve enterprise management level, to stabilize the market and production and R & D team, and providing technical reserves, in the industry

Intense competition to achieve comparative advantage.

Power lithium-ion battery development trend of the future must be high-capacity, high security, long life and convenient quick release so quick charge.

Enterprises should focus on these trends come to work prepared in advance, ahead of accumulation of related technologies, related materials well in advance the research, development and application. So in the future will take the forefront in the world. Power lithium-ion battery will be accompanied by the increasing awareness of environmental issues the attention and expectations for continuous improvement of electric cars which have developed rapidly, with the gradual power lithium-ion battery applications, the battery module is the ultimate result. At present, enterprises face more difficult issue is diversification of customer needs, resulting in the diversification of products is not conducive to large-scale expansion and improve the consistency of the battery, enterprises need to constantly in the pre-client applications based on the accumulation of experience, and explore the module of market demand, and gradually improving their internal standardization and modular, I hope the Government can as soon as possible modular battery market analysis, introduction of relevant standards, thus reducing the company’s products model, in order to lay the foundation for the production of large quantities.

For the growing demand, companies need to ensure the stability of existing products and future product planning and technical reserves, learn from Japan and other lithium-ion batteries more countries, research experiences and lessons learned to continuously improve our competitiveness.
