Title: Alkaline battery
Inventor: YASUDA HIDEO
IPC: H01M4/26
Filed: 1979-10-17
Abstract: PURPOSE:To enhance the performances and reduce the manufacture cost of an alkaline battery by using metal cadmium made by a given substitution reaction as a plate, and omitting the formation of the plate which might be conducted before sealing the battery. CONSTITUTION:The negative plate of an alkaline battery is made of metal cadmium, which is produced by a substitution reaction.
