Abstract
A positive electrode material includes a coated active material including a positive electrode active material and a coating layer and a first solid electrolyte. The coating layer contains a second solid electrolyte and covers at least a portion of a surface of the positive electrode active material. The first solid electrolyte is represented by the following Formula (1): Liα1M1β1X1γ1 Formula (1) where α1, β1, and γ1 each independently represent a positive real number; M1 includes calcium, yttrium, and at least one rare earth element other than yttrium; X1 includes at least one selected from the group consisting of F, Cl, Br, and I. The second solid electrolyte is softer than the first solid electrolyte.
