全固体電池
Document Type and Number:
Japanese Patent JP7218751
Kind Code:
B2
Abstract:
A main object of the present disclosure is to provide an all solid state battery capable of decreasing the heating value while suppressing the internal resistance increase. The present disclosure achieves the object by providing an all solid state battery comprising an anode active material layer, and an anode current collector, and the anode active material layer includes an anode active material whose total volume expansion rate, due to charge, is 14% or more, the anode current collector includes a coating layer including an oxide active material, on a surface of the anode active material layer side, and a ratio of a thickness of the coating layer to a thickness of the anode active material layer is 3% or more and 13% or less.
