SULFUR-CONTAINING MATERIAL, SULFUR-CONTAINING BATTERY MATERIAL, ELECTRODE AND BATTERY

Provided is a sulfur-containing material including a sulfur-modified compound, wherein the sulfur-containing material has a total content of sulfur of 50 mass % or more, and a ratio (A/B) of a maximum peak intensity (A) at a diffraction angle (2θ) that falls within a range of from 23.0° to 23.4° to a maximum peak intensity (B) at a diffraction angle (2θ) that falls within a range of from 24.8° to 25.2°, the ratio being obtained in powder X-ray diffraction using a CuKα ray, of 1.5 or less (A/B≤1.5).
