Abstract: An all-solid-state lithium-ion secondary battery includes a cathode active material, an anode active material, a solid electrolyte between the cathode and anode active materials, and an intermediate layer between the solid electrolyte and the cathode active material. The cathode and anode active materials are able to store and release a lithium ion. The solid electrolyte has lithium ion conductivity. The intermediate layer is constituted of elements including all elements constituting the cathode active material. A lithium ion in the intermediate layer is less ionic than that in the cathode active material.
