Abstract
A main object of the present disclosure is to provide an all solid state battery in which increase of internal resistance is suppressed. The present disclosure achieves the object by providing an all solid state battery including a cathode, an anode, and a solid electrolyte layer arranged between the cathode and the anode, wherein: the anode includes an anode active material layer and an anode current collector; the anode active material layer contains an anode active material, a sulfide solid electrolyte, and a molten salt of which melting point is 30° C. or more and 80° C. or less; and the anode current collector is a current collector in which a sulfidation due to the sulfide solid electrolyte occurs.
Claims5
An all solid state battery comprising a cathode, an anode, and a solid electrolyte layer arranged between the cathode and the anode, wherein:
- the anode includes an anode active material layer and an anode current collector;
- the anode active material layer contains an anode active material containing a Si element, a sulfide solid electrolyte, and a molten salt of which melting point is 30° C. or more and 80° C. or less;
- the molten salt is lithium bis(fluorosulfonyl)amide (Li-FSA) and cesium bis(fluorosulfonyl)amide (Cs-FSA);
- and
- the anode current collector is a current collector in which a sulfidation due to the sulfide solid electrolyte occurs.
