Scholars are expected: the battery technology will take place in two changes

Lithium-ion battery charge and discharge mechanism completely different from the lead-acid batteries, nickel cadmium batteries and nickel-metal hydride batteries. After the three commonly used battery electrode by electrochemical reaction, conversion of other compounds to store electricity. The lithium-ion battery is by coating the electrode active material on the storage and release of lithium ion, lithium ion through the electrode active material on the "embed" and "emerge" through the so-called "de-embedded phenomenon" to store energy.

Because of recent times have been found in a variety of institutions can be stored (ie, embedded), release (or prolapse) ion electrode active materials, solid electrolytes and polymer membranes, together with the people of these newly discovered substances in-depth study, and then On this basis, but also the structure of the innovative transformation of the battery, so "embedded de-ion battery," the performance of rapid increase.

Japan, U.S. and German scholars generally expected that by 2015, 2030, two years, embedded de-ion battery manufacturing costs will be reduced to now the price of 1 / 7 and 1 / 40. Currently, many foreign research institutions are stepping up to this practical battery technology research, and some have been in the waiting stage of industrialization. In other words, expected from the pages of this century, the embedded de-ion battery performance, structure and manufacturing costs will certainly meet people for the high-pressure, high-capacity ion batteries have high hopes, the BEV, PHV in performance, the real price and have used a variety of advanced technology, continuous improvement of the M1 is still petrol passenger car class competition, and to mass production according to market principles (not funded by government or private sector), thereby reducing car pollutants and greenhouse gas emissions and change the car's "food" structure, making the car's driving energy costs significantly.

Found that can be used to "de-embedded response" many of the inorganic solid electrolyte conductivity is very high, very fast charge suitable for the manufacture of high voltage, high energy density batteries.

"Auto industry restructuring and revitalization plan" put forward in the next 3 years, China will form a 500,000 capacity all kinds of electric vehicles. To accomplish this task, ion battery production capacity must first be met. However, China has such advanced battery development and production planning? To production, a liquid electrolyte of the "iron battery"? Or laminated solid electrolyte for lithium ion batteries? Unknown. Japanese, German auto industry has been the driving force of the future of electric cars locked in the "laminated solid electrolyte for lithium ion batteries" on. However, lithium-ion battery manufacturers in China even the "liquid electrolyte lithium-ion battery" is also required for membrane materials can not be produced so far, all have to rely on imports more expensive, accounting for 30% of the cost of power than the battery! In recent years, the international battery manufacturers and multinational auto companies generally composed of various types of joint ventures, joint development of electric vehicle battery technology, but few of such examples. In this set up on the basis of the 50 million electric vehicle production capacity, is an independent type or attachment type, difficult to judge.

Recently discovered a large number of excellent lithium ion battery or "non-lithium batteries," the alternate positive and negative active material for a new generation of vehicle power battery research and development, promote the use of essential, but also will promote the rapid development of various types of electric vehicles. For example, the relevant foreign agencies have recently found that "sulfide lithium-ion conductor" became crystal material, the existing lithium-ion conductivity is high, there are wide "electrochemical window", therefore, it is likely to become a solid battery electrolyte (solid electrolyte). In addition, the glass state lithium-ion solid electrolytes, non-integer ratio of compounds and some other lithium-ion battery cathode, anode active materials that alternate, but also much industry attention.

To be sure:

First, will debut in 2015's "preemption" battery will not be the "iron battery", is likely to be non-lithium compounds "embedded de-ion batteries."

Second, will be available before and after 2030 the "innovative" batteries will not be the "iron battery", it should be a high-capacity, low cost, "embedded detachable battery," it will find extensive use of new types of electrode active materials and auxiliary materials. For the second conclusion of the discussion, will be launched in the next column.
