A main object of the present disclosure is to provide an all solid state battery with capacity durability. The present disclosure achieves the object by providing an all solid state battery including a cathode layer, an anode layer, and a solid electrolyte layer arranged between the cathode layer and the anode layer, wherein the anode layer contains a granulated body including a Si-based active material and a molten salt, which is in a solid state at 25° C.

All solid state battery, method for producing all solid state battery, and method for recovering all solid state battery

A solid-state battery includes: a first current collector layer having a first current collector tab protruding from one side of a quadrilateral; a first active material layer laminated on the first current collector layer; a second current collector layer having a second current collector tab protruding from one side of a quadrilateral; a second active material layer laminated on the second current collector layer; and a solid electrolyte layer arranged between the first active material layer and the second active material layer and including a polymer electrolyte, wherein, in three sides other than the one side where the first current collector tab is arranged, the solid electrolyte layer is arranged so as to cover end surfaces of the first current collector layer and the first active material layer.
