Abstract
An all-solid-state secondary battery including: a positive electrode active material layer including a positive electrode active material and a sacrificial positive electrode material having an oxidation-reduction potential which is less than a discharge voltage of the positive electrode active material; and a negative electrode active material layer including a negative electrode active material including an element alloyable with lithium or that forms a compound with lithium; and a solid electrolyte layer between the positive electrode active material layer and the negative electrode active material layer, wherein the sacrificial positive electrode material includes a sacrificial active material and a conductive agent.
