Abstract
The main object of the present invention is to provide a sulfide solid electrolyte material with less hydrogen sulfide generation amount. The present invention solves the above-mentioned problem by providing a sulfide solid electrolyte material obtained by using a raw material composition containing Li2S and sulfide of an element of the fourteenth family or the fifteenth family, characterized by not substantially containing cross-linking sulfur and Li2S.
