Tokyo, Nov 19, 2009 - (JCN Newswire) - Showa Denko K.K. (SDK) will develop next-generation liquid electrolytes for lithium ion batteries (LIBs) using a new and stable electrolyte salt (Li2B12FxH12-x), aiming to soon commercialize the liquid electrolytes for use in large LIBs for vehicles.
The new electrolyte salt, which can replace conventional electrolyte salts, has been developed by Air Products and Chemicals, Inc. (APD), of the United States.
SDK has obtained a license from APD to use APD's patents and know-how concerning the new electrolyte salt for automotive and other applications. The terms of the license agreement were not released. The two companies have separately been developing next-generation battery materials for many years.
SDK will utilize APD's new electrolyte salt in combination with SDK's proprietary liquid electrolyte technology, aiming to soon commercialize next-generation formulated liquid electrolytes for LIBs. Together with anode material for LIBs in electric vehicles, SDK is planning to sell JPY 60 billion of advanced battery materials in 2020.
Compared with conventional electrolyte salts, the new electrolyte salt is anticipated to be advantageous in that it minimizes reaction with water (a cause of deterioration of batteries); does not generate cathode-corroding acids with the lapse of time; and is capable of operating at higher temperatures which are desirable for automotive applications. SDK's next-generation liquid electrolyte is aimed to prevent or inhibit the risk of ignition resulting from overcharge of LIBs, and battery deterioration due to oxidants generated in liquid electrolytes after repeated charges and discharges and, at the same time, increase battery capacity.*
SDK will expand its lineup of fluorine compounds by advancing into the area of LIB components, in addition to electronics applications. In view of the global warming issue and limitations of mineral resources, we will continue providing individualized materials and technologies for environmental protection and energy conservation, thereby contributing to the sound growth of society.
*Battery capacity refers to the total amount of electric current, in terms of ampere-hour (Ah), produced from the beginning to the end of the use of a battery, without charges during the course.
