Solid electrolyte material, method for producing solid electrolyte material, positive electrode material, and battery

Abstract

A solid electrolyte material includes Li, Al, and X. X represents anions including F, and the solid electrolyte material has a specific surface area of greater than or equal to 16 m2/g. A method for producing the solid electrolyte material includes pulverizing a mixture containing a solvent and a raw material composition containing compositional components of the solid electrolyte material by wet pulverization. The positive electrode material contains a positive electrode active material coated with the solid electrolyte material.
