Solid electrolyte material and battery using same

Abstract

A solid electrolyte material of the present disclosure includes Li, Zr, Y, Cl, and O, wherein the molar ratio of O to Y in the entire solid electrolyte material is greater than 0 and less than or equal to 0.80, and the molar ratio of O to Y in the surface region of the solid electrolyte material is larger than the molar ratio of O to Y in the entire solid electrolyte material. A battery of the present disclosure includes a positive electrode, a negative electrode, and an electrolyte layer disposed between the positive electrode and the negative electrode, wherein at least one selected from the group consisting of the positive electrode, the negative electrode, and the electrolyte layer contains the solid electrolyte material of the present disclosure.
