All-solid-state rechargeable batteries

Abstract

An all-solid-state rechargeable battery includes a positive electrode having a positive electrode current collector, a positive electrode active material layer on the positive electrode current collector, the positive electrode active material layer including a positive electrode active material and a sulfide solid electrolyte, and a safety functional layer on the positive electrode active material layer, the safety functional layer including an olivine positive electrode active material, a negative electrode, and a solid electrolyte layer between the positive electrode and the negative electrode, the solid electrolyte layer including the sulfide solid electrolyte.
