Abstract:
(EN) The present invention improves the battery characteristics of an all-solid-state LIB. A positive electrode active material according to the present invention comprises particles and coating layers; the particles are represented by composition formula LiaNibCocMndOe (wherein 1.0 ≤ a ≤ 1.05, 0.8 ≤ b ≤ 0.9, 1.8 ≤ e ≤ 2.2, and (b + c + d) = 1); the coating layers are represented by composition formula LiNbO3; and the specific surface area and the particle diameter of this positive electrode active material satisfy the relational expression shown below. Y ≤ 3.5 × X-1 (In the relational expression, X is the particle diameter (μm) of the active material, and Y is the specific surface area (m2/g).)
(FR) La présente invention améliore les caractéristiques de batterie d’une LIB totalement solide. Un matériau actif d’électrode positive selon la présente invention comprend des particules et des couches de revêtement ; les particules sont représentées par la formule de composition LiaNibCocMndOe (où 1,0 ≤ a ≤ 1,05, 0,8 ≤ b ≤ 0,9, 1,8 ≤ e ≤ 2,2, et (b + c + d) = 1) ; les couches de revêtement sont représentées par la formule de composition LiNbO3 ; et l’aire de surface spécifique et le diamètre de particules de ce matériau actif d’électrode positive satisfont à l’expression relationnelle indiquée ci-dessous. Y ≤ 3,5 × X−1 (Dans l’expression relationnelle, X est le diamètre de particules (µm) du matériau actif, et Y est l’aire de surface spécifique (m2/g).)
(JA) 全固体LIBにおける電池特性を改善すること。正極活物質であって、前記正極活物質は、粒子と被覆層とを含み、前記粒子は以下の組成で表され、LiaNibCocMnde(ここで、1.0≦a≦1.05、0.8≦b≦0.9、1.8≦e≦2.2、b+c+d=1)前記被覆層は、LiNbO3で表され、前記正極活物質の比表面積と粒径が以下の関係を満たす、正極活物質。Y≦3.5×X-1(X=活物質粒径(μm)、Y=比表面積(m2/g))
