Lithium secondary battery

摘要

A lithium ion conductive inorganic solid electrolyte is used as an electrolyte in a lithium secondary battery which uses a transition metal chalcogenide or a lithium. transition metal chalcogenide as an active material for negative electrode. There is provided a lithium secondary battery improved in reversibility and in charge and discharge cycle characteristics as compared with lithium secondary batteries which use a liquid electrolyte or a molten salt electrolyte as the electrolyte.
