Claim 0:
1. A method for producing a sulfide solid electrolyte containing a lithium atom, a sulfur atom, a phosphorus atom, and a halogen atom, the method comprising:
mixing and reacting a complex (1) with a separate complex (2);
wherein:
the complex (1) contains a sulfide containing a lithium atom, a sulfur atom, and a phosphorus atom as constituent elements; and
the complex (2) contains a halide containing a lithium atom and a halogen atom as constituent elements;
and wherein:
the sulfide solid electrolyte does not have a diffraction peak at 2θ=17.5° and 26.1° corresponding to a crystalline Li3PS4, in X-ray diffractometry using a CuKα ray.
