Beschreibung
Zusammenfassung:An all-solid-state secondary battery, wherein: an anode current collector that contains copper or copper alloy; a cathode current collector comprising aluminum, aluminum alloy or stainless steel, provided opposite to the anode current collector; an anode active material layer formed there between from the anode current collector side on the surface of the anode current collector; a solid electrolyte layer comprising a sulfide solid electrolyte that contains a monovalent or divalent metal and sulfur; and a cathode active material layer formed on the surface of the cathode current collector are layered successively, is used. A sulfidation resistant layer is formed on the surface of the anode current collector on which the anode active material layer is formed. Or, the surface of the anode current collector on which the anode active material layer is formed has a compressive strength of 1250 to 3000 MPa.
