Abstract
Copper reacts with a sulfide solid electrolyte to generate copper sulfide when an anode current collector layer made from copper, and an anode mixture layer containing the sulfide solid electrolyte are used to compose an anode, and the resistance of the interface between the anode current collector layer and the anode mixture layer increases. To alloy an anode current collector layer to lower the reactivity to a sulfide solid electrolyte, specifically, an anode includes: an anode mixture layer; and an anode current collector layer that is in contact with the anode mixture layer, wherein the anode mixture layer contains an anode active material and a sulfide solid electrolyte, and at least a surface of the anode current collector layer is made from material that contains an alloy of copper and metal of a higher ionization tendency than copper, the surface being in contact with the anode mixture layer.
