Secondary battery

Abstract

A secondary battery includes a positive electrode, a negative electrode, and an electrolyte layer including an electrolyte solution that conducts a conductive ion between the positive electrode and the negative electrode. The positive electrode includes a positive electrode active material and an oxide-based ionic conductor. The positive electrode active material is in contact with at least a part of the oxide-based ionic conductor. The electrolyte solution exists between the positive electrode active material and the oxide-based ionic conductor to allow the conductive ion to be electrochemically inserted into the oxide-based ionic conductor.
