Abstract
A positive electrode material contains at least one positive electrode active material, a solid electrolyte, and a coating material. The solid electrolyte is represented by formula (1), LiαMβXγ (1) where α, β, and γ are each independently a value greater than 0, M includes at least one element selected from the group consisting of non-Li metals and metalloids, and X includes at least one selected from the group consisting of F, Cl, Br, and I. The coating material covers the surface of the positive electrode active material and contains lithium carbonate.
