POSITIVE ELECTRODE MATERIAL AND BATTERY

Title:

POSITIVE ELECTRODE MATERIAL AND BATTERY

Document Type and Number:

WIPO Patent Application WO/2023/132304

Kind Code:

A1

Abstract:

A positive electrode material 1000 according to the present disclosure comprises a mixture of a positive electrode active material 110, a solid electrolyte 100, and a conductive material 140. The ratio of the volume of the positive electrode active material 110 relative to the total volume of the positive electrode active material 110 and the solid electrolyte 100 is 50-90%. The positive electrode material 1000 satisfies 30≤X≤80, with X being a value found via equation (1).　Equation 1: X=A×B (In equation (1), A is the BET specific surface area (m2/g) of the conductive material 140, and B is the ratio (%) of the mass (g) of the conductive material 140 relative to the mass (g) of the positive electrode active material 110.)
