Scholars are expected that battery technology will be taken place two changes

The rechargeable lithium-ion battery discharge completely different from the mechanism of lead-acid batteries, nickel cadmium batteries and nickel-metal hydride batteries. After the three commonly used battery electrode through the electrochemical reaction occurs, transformation of other compounds to store electrical energy. The lithium-ion battery is through the coating in the active electrode materials for lithium-ion storage and release, that is, through the activity of lithium-ion electrode materials in the "embedded" and "off" by the so-called "embedded off phenomenon" to store energy.
As a result of recent research institutions have found a very wide variety of storage (that is, embedded), the release (ie, prolapse) ion activity of the electrode materials, solid-state and polymer electrolyte membrane, coupled with the discovery of these new in-depth study materials, further On this basis and structure of the battery innovation transformation,compaq evo n600 battery, therefore, "embedded ion battery off" rapidly improve the performance.
Japan, the United States and German scholars are expected by 2015, two years in 2030, embedded ion batteries from the manufacturing costs will be lowered to the price is now 1 / 7 and 1 / 40. At present, many research institutions abroad, are stepping up to this practical battery technology research, and some have been waiting at the stage of industrialization. In other words, is expected in the pages of this century, the embedded ion battery pack from the performance,dell inspiron 1520 battery, structure and manufacturing costs will certainly meet people's high-pressure, high-capacity ion batteries high expectations that are attached to BEV, PHV can be in terms of performance, prices on the real and have used a variety of advanced technology, still in progress, M1-type gasoline engine passenger cars competitive, and can be mass-produced in accordance with the laws of the market (rather than rely on government-funded or non-governmental organizations), thereby reducing car pollutants and greenhouse gas emissions and change the car's "food" structure, so that the cost of cars traveling significantly decrease energy consumption.
The study found that can be used in the "embedded off response" of many inorganic solid electrolyte conductivity is very high, very suitable for the manufacture of fast charging of high voltage, high energy density batteries. "The automobile industry restructuring and revitalization of planning" make in the next 3 years, China will form a 500,000 electric vehicles of various capacity. To accomplish this task, ion battery production capacity must be achieved. However, China has such advanced battery R & D and production planning it? To production, is a liquid electrolyte of the "iron hp pavilion dv2000 battery"? Or laminated solid electrolyte-based lithium-ion batteries? Unknown. Japan and Germany the future of the automotive industry has been the power source for electric vehicles locked in the "stack-based solid electrolyte for lithium-ion batteries" on. However, China's lithium-ion battery manufacturers even "liquid electrolyte lithium-ion battery," has been required to divide the material can not be production, all have to rely on imports, which is very expensive, accounting for the cost of motive power for more than 30%! In recent years, international battery manufacturers and multinational companies generally composed of various types of automobile joint ventures, joint development of electric vehicle battery technology, China has few such examples. In this built on the basis of the 500,000 annual production capacity of electric cars is an independent or dependent type, and it is not difficult to determine.
In recent years, found a large number of excellent lithium-ion batteries or "non-lithium batteries," the alternate cathode and anode active materials, for a new generation of vehicle battery research and development driving force to promote the use of essential, but also will promote the rapid development of various types of electric vehicles. For example, the recent discovery of relevant institutions abroad, "sulfide lithium-ion conductor" became crystal material, the existing high lithium ion conductivity, and wide "electrochemical window", therefore, it is likely to become a solid battery electrolyte (solid electrolyte). In addition, the glass-state lithium-ion solid electrolyte, nonstoichiometric compounds and some other lithium-ion hp pavilion dv6000 battery,hp pavilion dv2500 battery,dell latitude c640 battery cathode, anode active materials found alternate, also has been the industry's importance.
