SULFIDE SOLID ELECTROLYTE MATERIAL, BATTERY, AND PRODUCING METHOD FOR SULFIDE SOLID ELECTROLYTE MATERIAL |
摘要 |
A main object of the present invention is to provide a sulfide solid electrolyte material having favorable ion conductivity and low reduction potential. The present invention solves the above-mentioned problem by providing a sulfide solid electrolyte material including an M1 element (such as a Li element), an M2 element (such as a Ge element, a Si element and a P element) and a S element, wherein the material has a peak at a position of 2θ=29.58°±0.50° in X-ray diffraction measurement using a CuKα line; and when a diffraction intensity at the peak of 2θ=29.58°±0.50° is regarded as IA and a diffraction intensity at a peak of 2θ=27.33°±0.50° is regarded as IB, a value of IB/IA is less than 0.50, and M2 contains at least P and Si. |
