ALL-SOLD BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a sulfide-based all-solid battery capable of suppressing local heat generation due to charging, short-circuit, etc.SOLUTION: Disclosed is an all-solid battery includes; a positive electrode layer and a negative electrode layer obtained by coating a mixture on one surface of each current collector foil of a positive electrode current collector foil and a negative electrode current collector foil; and a sulfide solid electrolyte layer between the positive electrode layer and the negative electrode layer. A copper foil is provided on the positive electrode current collector foil of the positive electrode layer. A positive electrode mixture, the positive electrode current collector foil and the copper foil are laminated on the positive electrode layer side in this order. The sulfide solid electrolyte layer is provided in the positive electrode mixture. The positive electrode current collector foil has a through-hole. The through-hole is filled with resin melted at a predetermined temperature.SELECTED DRAWING: None
