Abstract
A positive electrode material includes a positive electrode active material, a cover layer that covers at least part of a surface of the positive electrode active material and that contains a first solid electrolyte material, and a second solid electrolyte material that is a material different from the first solid electrolyte material. The first solid electrolyte material contains Li, M, and X and does not contain sulfur. M represents at least one element selected from the group consisting of metal elements other than Li and semi-metal elements, and X represents halogen elements including Cl.
