Complex comprising sulfur, a method for manufacturing the same, and a method for manufacturing a solid electrolyte

Abstract

To provide a sulfur-containing complex having few impurities, a method for producing the complex at a higher production efficiency, and a method for producing a solid electrolyte using the complex, a sulfur-containing complex, containing a lithium sulfide and a lithium halide, exhibiting, in X-ray diffractometry using a CuKα ray, the diffraction angle of the peak of lithium halide shifting toward the diffraction angle of the peak of lithium sulfide, and not containing an oxygen-containing lithium halide represented by Li3OX (where X represents a halogen element) is provided. And a production method for a sulfur-containing complex including heating a solution containing a lithium hydrosulfide and a lithium halide in the presence of hydrogen sulfide is also provided.
