Abstract: front page image
(EN)A sulfide solid electrolyte which contains lithium, phosphorus, sulfur, chlorine and bromine, while having a diffraction peak A at 2θ = 25.2 ± 0.5 deg and a diffraction peak B at 2θ = 29.7 ± 0.5 deg in powder X-ray diffractometry using a Cu-Kα ray, and wherein: the diffraction peak A and the diffraction peak B satisfy formula (A); and the molar ratio c (Cl/P) of the chlorine to the phosphorus and the molar ratio d (Br/P) of the bromine to the phosphorus satisfy formula (1). 0.845 < SA/SB < 1.200 (A) (In the formula, SA represents the area of the diffraction peak A; and SB represents the area of the diffraction peak B.) 1.2 < c + d < 1.9 (1)
(FR)La présente invention concerne un électrolyte solide au sulfure qui contient du lithium, du phosphore, du soufre, du chlore et du brome, tout en ayant un pic de diffraction A à 2θ = 25,2 ± 0,5 degrés et un pic de diffraction B à 2θ = 29,7 ± 0,5 degrés en diffraction des rayons X sur poudre en utilisant un rayonnement Cu-Kα, et dans lequel : le pic de diffraction A et le pic de diffraction B satisfont à la formule (A) ; et le rapport molaire c (Cl/P) du chlore au phosphore et le rapport molaire d (Br/P) du brome au phosphore satisfont à la formule (1). 0,845 < SA/SB < 1,200 (A) (dans la formule, SA représente l’aire du pic de diffraction A ; et SB représente l’aire du pic de diffraction B.) 1,2 < c + d < 1,9 (1).
