No. 185: Technology to build a thin-film lithium-ion battery in the normal temperature process (November 11, 2010)

Toyota Motors and National Institute of Advanced Industrial Science and Technology (AIST) jointly built an all-solid thin-film lithium-ion battery in the normal temperature process for the first time in the world. Different from the existing thin film technology, the new technology shortens production time, increases productivity, and reduces production cost because it does not need heating. The two organizations used the aerosol deposition method that is the high-speed and normal-temperature coating process of ceramics materials developed by AIST. They made the oxide system positive-electrode material, negative-electrode material and fixed electrode material thinner and laminated, and built a trilaminar all-solid thin-film lithium-ion battery on trial. They confirmed the charge-discharge characteristics as a battery. Details of the research results will be presented in the 3rd International Congress on Ceramics scheduled between 14th and 18th of coming November in Osaka.
