Successful development of a highly safe lithium-ion secondary battery prototype using a new, hardly combustible electrolyte
Hitachi and the Institute of Multidisciplinary Research for Advanced Materials of Tohoku University today announced the successful development of a high-safety prototype lithium-ion secondary battery (LIB) using a new, hardly combustible electrolyte with a flash point higher than conventional organic electrolyte solutions.
Battery performance characteristics such as charge and discharge, etc. were confirmed using a 100Wh-capacity laminated battery. Further, the incombustibility of the prototype LIB was also demonstrated using the nail penetration test, which causes combustion in LIBs using conventional organic electrolyte solutions. The newly developed technology will make it possible to ensure safety while increasing the capacity and energy density of LIBs for vehicles and consumer products, etc.
