Iron battery technology breakthroughs
BYD F1 Dell Inspiron 1420 Battery, or will have electric car market at the same
Moderator: You may also be referred to the F3-e, I also mentioned at the beginning, the media commented that, F3-e is the BYD in the future be able to beat other rivals as a “trump card”, you are such a thought do?
Xia Zhi-Bing: We also hold this view, the electric car is our own call it our own “nuclear weapons” just when I say “333″ strategy inside the last three years of strategy. Indeed, we had to do when the car, when there is this idea, we have to do the battery is the world’s top experts in business, we build up the brand of motor vehicles, the future introduction of electric vehicles, may be we are the first, and also the car we had to do dream Dell Inspiron 1501 Battery, and a basic condition.
So we launched F3 on the basis of F3-e, the current car to do this test, the last three years, is through the concept of electric cars or electric vehicles the technology come and go to break the tradition of the original automotive industry by the engine or transmission technology so dominated the field, through technology, generation gap, to break the industry pattern. After all, foreigners do the engine did 100 years, people’s accomplishments than we do have a deep accumulation, we have more than him in this area, relatively speaking, is more difficult. But the battery industry, they are in front of us is “primary.” Through this advantage, through the formation of technology, generation gap, to break the pattern Dell Inspiron 1520 Battery of industry now. This is our future, or we think is a “nuclear.”
Moderator: There is a lot of User comments, said he was looking forward to this pure battery electric vehicles F3-e-market, because oil prices are now too expensive.
Xia Zhi-Bing: The Future We have a family, not just out of F3 in this model will be F3, next year in March, there will be listed on F1 this model, which was listed, so if the research and development to promote optimism, it is possible we have F1 hybrid , and the F1 2 conventional gasoline vehicles listed at the same time, I have not previously spoken in public, this optimistic message. Because at present we have made some breakthroughs in the field of batteries, because we have a technology called iron fujitsu lifebook b6220 battery technology, has made some breakthroughs, has made an industry of it, if the promotion goes well, probably around March next year, We will also be on the F1 car was electric cars same time.

Important innovation in point of lithium-ion battery
Lithium iron sony np-bg1 phosphate oxygen vacancy: According to independent research and development of a unique synthetic method to prepare a reversible storage capacity of 160mAh / g of oxygen vacancies lithium iron phosphate cathode material, recycling 500 times the capacity no attenuation, especially with a high magnification (10C) discharge capacity.
Lithium Cobalt Nickel Manganese: You can replace the lithium cobalt oxide lithium nickel manganese cobalt cathode material was successfully developed, the development of a unique lithium precursor synthesis and processing technology, 80% of the cobalt has been replaced by manganese and nickel, and realized its crystal particle size control, synthetic materials, a reversible capacity of 165mAh / g, higher than that of lithium cobalt oxide 10%, cycle life of up to 500 times, while the cost of less than 50% of lithium cobalt oxide has been in a small trial built on the basis of an annual output of 150 tons of pilot lines.
Improve the lithium nikon en-el3manganese oxide spinel: developed with independent intellectual property rights of a Al2O3 surface modification technology to produce a reversible capacity of 107mAh / g, 55 ℃ cycle capacity retention rate of 200 times greater than 90%, is the first one available in the hybrid battery with high power lithium-ion battery materials, protects the major projects of high-power electric vehicles, lithium-ion battery the smooth progress of the project.
Composite anode materials: development of a composite anode materials, reversible lithium storage capacity has reached 600mAh / g, reached the international advanced level.
Graphite Nano-Fiber Conductive Additives: To achieve the right carbon fiber diameter and length distribution of control, develop a graphite nanofibers conductive additives, solving the localization problem of nikon en-el4 such additives.
Battery Research: 2004 Star Constant this material-based high-power hybrid cars with lithium-ion nikon en-el4a batteries fully electric vehicles passed the 863 major projects testing the unity of the organization than the power reaches 1200W/kg, the performance ranking of international advanced level, star-heng 10Ah high-energy type and 7.5Ah high-power lithium-ion battery through the United States UL safety test, becoming the first Chinese mainland through a UL-certified Li-ion power digital camera battery, battery for this kind of paved the way for the international market.

Targeting future and achieve industry
Than the fujitsu lifebook e8310 battery existing carbon materials (372 mAh / g) a higher-capacity anode material for studying the hot, the tin oxide was first found to have excellent lithium storage performance, leading people began to study a series of metals and oxides based on The anode material, however, tin, silicon, etc., as anode materials for lithium-ion batteries a fatal question: charge-discharge process, with the embedded lithium repeated extrusion, volume change of up to 300% -400%, resulting in the mechanical stability of the lower electrode, powder materials are also due to the gradual failure occurs, the cycle of poor performance.
Huang Xue-Jie said, nano-alloyed tin-based materials can overcome this weakness has been obtained in the SONY’s Nexlion application, the physical location in 1998 issued a paper pointed out that the nano-technology is to improve the cycle performance of such materials, an effective way. Domestic Chinese steel Research Science and Technology Corporation in the support of 863 has been initially developed with certain cyclic stability of the tin-based materials. Around the world, with a high specific capacity fujitsu Esprimo Mobile V5515 Battery of the non-carbon negative electrode material is in a large-scale commercial application of the initial stage, using three-dimensional sets of fluid materials, lithium-ion battery anode materials to improve the electrochemical performance and is the current international field of lithium-ion battery A major research focus. Compared with the traditional two-dimensional copper foil, three-dimensional sets of fluid materials, active substances can provide a more favorable environment conductive to shorten the average electron transport within the porous electrode distance, thereby reducing the resistance of a pole piece, reducing the high current charging and discharging of the electrode produced a very phenomenon; more importantly, the three wiki body can to some extent alleviate the high-capacity active material than the “volume effect”, reducing stress on the electrode structure damage, thereby improving the electrode cycle life and charge-discharge efficiency.
Currently, Suzhou Star Constant Power Co., Ltd Li-ion power battery power has reached more than 120Wh/kg, accounts for the domestic electric bicycle lithium-ion battery for more than 80% of the market, some products have entered the international fujitsu Esprimo Mobile V5535 Battery market.
“Eleventh Five-Year” period, 863 plans to continue to provide support for vehicle power battery and energy storage battery research and development of key materials, launch a series of projects.
Huang Xue-Jie said that with the power type lithium ion battery materials, the process of industrialization in-depth, it will greatly promote the motive power industry, technological advances, in terms of safety, high-temperature cyclic nature of life, or from in terms of manufacturing costs, will be the motive power of the product promotion and market development to a new level. On the other hand, the new, power-based lithium-ion fujitsu Esprimo Mobile V5555 Battery cathode materials for the development of upstream raw material producers also put forward higher requirements for the upstream industry in the purity of the product as well as manufacturing cost, the technological progress and development.
“I believe the next few years, lithium-ion battery powered electric vehicles will gradually occupy the fujitsu lifebook b6210 battery market.” HUANG Xue-Jie said.
