Abstract:
(EN) The purpose of the present invention is to improve ion conductivity of a solid electrolyte, and to improve the battery characteristics of an all-solid battery. The solid electrolyte is a solid electrolyte having a garnet-type crystal structure. The solid electrolyte is represented by general formula (Li7–ax+yAx)La3(Zr2–yBy)O12 (where A is at least one type of element selected from the group consisting of Mg, Zn, Al, Ga, and Sc, a is the valence of A, B is at least one type of element selected from the group consisting of Al, Ga, Sc, Yb, Dy, and Y, and 0 < x < 1.0, 0 < y < 1.0, 5.5 < 7 – ax + y < 7.0).
(FR) L'objet de la présente invention est d'améliorer la conductivité ionique dans un électrolyte solide et d'améliorer les caractéristiques de batterie d'une batterie tout solide. L'électrolyte solide est un électrolyte solide ayant une structure cristalline de type grenat. L'électrolyte solide est représenté par la formule générale (Li7–ax+yAx)La3(Zr2–yBy)O12 (où A est au moins un type d'élément choisi dans le groupe constitué par Mg, Zn, Al, Ga et Sc, a est la valence de A, B est au moins un type d'élément choisi dans le groupe constitué par Al, Ga, Sc, Yb, Dy, et Y, et 0 < x < 1,0, 0 < y < 1,0, 5,5 < 7 – ax + y < 7,0).
(JA) 固体電解質のイオン伝導度を向上し、全固体電池の電池特性を向上する。 固体電解質は、ガーネット型の結晶構造を有する固体電解質である。固体電解質は、一般式(Li7-ax+y)La(Zr2-y)O12(Aは、Mg、Zn、Al、Ga及びScからなる群から選ばれた少なくとも一種の元素であり、aはAの価数であり、Bは、Al、Ga、Sc、Yb、Dy及びYからなる群から選ばれた少なくとも一種の元素であり、0<x<1.0、0<y<1.0、5.5<7-ax+y<7.0)で表される。
