Development of large-capacity laminated lithium ion rechargeable battery (High power type)

The applications of lithium ion rechargeable batteries have recently been expanding in the high current requirement fields as these devices begin to be used in electrical tools such as for impact drivers and hammer drills. NEC TOKIN has newly developed and commercialized a 3Ah class, high power, large-capacity lithium ion rechargeable battery by applying its expertise in materials technology and associated techniques that have been gained in the commercialization of large-capacity batteries. The newly developed high power, large-capacity lithium ion rechargeable battery, "IML126070" is capable of a continuous 30A discharge and a quick 13-minute discharge (90% recharging) due to; 1) the use of electrode materials proven in the development of electrically assisted bicycles; 2) a review of electrode specifications to provide compatibility with high current discharge and rapid charging, and; 3) improvement and optimization of the current collector structure to provide compatibility with high current and higher energy levels.
