Abstract

Batteries using a positive electrode mixture comprising a sulfur-based positive electrode active material have room for improvement in terms of cycle characteristics. The battery of the present disclosure comprises a positive electrode mixture layer, an electrolyte layer, and a negative electrode. The positive electrode mixture layer comprises a sulfur-based active material, a P-containing sulfide, and carbon. BET specific surface area of the carbon is 350 m<2>/g or more. A molar ratio P/S between P and S contained in the positive electrode mixture layer is greater than 0.06 and less than 0.24.
