Abstract
(EN) The present invention addresses the problem of providing a solid electrolyte sulfide material which has satisfactory Li-ion conductivity in low-temperature environments. The invention provides a solid electrolyte sulfide material characterized by containing elements M1 (e.g., Li element and Mg element), elements M2 (e.g., Ge element and P element), and S element, having a peak at a position of 2θ=29.58±0.50º in X-ray diffractometry using a CuKα line, and having no peak at a position of 2θ=27.33±0.50º or slightly having the peak, and characterized in that the replacement amount δ (%) of the divalent element(s) in the M1 elements is in such a range that the sulfide material at 0ºC shows a higher Li-ion conductivity than in the case of δ=0. Thus, the problem is solved.
(FR) La présente invention aborde le problème de fourniture d'un matériau sulfuré d'électrolyte solide qui possède une conductivité des ions de lithium satisfaisante dans des environnements à basse température. A cet effet, l'invention concerne un matériau sulfuré d'électrolyte solide caractérisé en ce qu'il contient des éléments M1 (par exemple, l'élément Li et l'élément Mg), des éléments M2 (par exemple, l'élément Ge et l'élément P), et l'élément S, ayant un pic à une position de 2θ=29,58±0,50º en diffraction des rayons X en utilisant une ligne CuKα, et n'ayant pas de pic à une position de 2θ=27,33±0,50º ou ayant légèrement le pic, et caractérisé en ce que la quantité de remplacement δ (%) du ou des éléments bivalents dans les éléments M1 est dans une plage telle que le matériau sulfuré à 0°C présente une conductivité des ions de lithium supérieure que dans le cas où δ=0. Ainsi, le problème est résolu.
