SULFIDE SOLID ELECTROLYTE MATERIAL SULFIDE GLASS SOLID-STATE LITHIUM BATTERY AND METHOD FOR PRODUCING SULFIDE SOLID ELECTROLYTE MATERIAL

摘要

It is an object of the present invention to provide a sulfide solid electrolyte material having high Li ion conductivity. The present invention relates to a film having a peak at 2? = 20.2 占 and a peak at 23.6 占 and a peak at 2? = 21.0 占 and 28.0 占 in X-ray diffraction measurement using CuK? Ray having Li, P, And the full width at half maximum of the peak at 2? = 20.2 is not more than 0.51 占 The present invention solves the above problems by providing a sulfide solid electrolyte material.
