Title (EN) NONAQUEOUS ELECTROLYTE SECONDARY BATTERY
(FR) BATTERIE SECONDAIRE À ÉLECTROLYTE NON AQUEUX
(JA) 非水電解質二次電池
Abstract:
(EN) A nonaqueous electrolyte secondary battery which comprises: a positive electrode; a separator; a negative electrode that faces the positive electrode, with the separator being interposed therebetween; and an electrolyte solution that contains a solvent and an electrolyte. This nonaqueous electrolyte secondary battery is configured such that the positive electrode contains a positive electrode material which contains a lithium nickel composite oxide that is represented by LiaNibM1-bO2 (wherein M represents at least one element selected from the group consisting of Na, Mg, Sc, Y, Mn, Fe, Co, Ni, Cu, Zn, Al, Cr, Pb, Sb and B; 0.95 < a ≤ 1.2; and 0.8 ≤ b ≤ 1). The electrolyte solution contains an ester compound C of an alcohol compound A and a carboxylic acid compound B; and at least one of the alcohol compound A and the carboxylic acid compound B is contained in an amount of 15 ppm or more relative to the mass of the electrolyte solution.
(FR) L'invention concerne une batterie secondaire à électrolyte non aqueux qui comprend : une électrode positive ; un séparateur ; une électrode négative qui fait face à l'électrode positive, le séparateur étant intercalé entre celles-ci ; et une solution électrolytique qui contient un solvant et un électrolyte. Cette batterie secondaire à électrolyte non aqueux est configurée de telle sorte que l'électrode positive contient un matériau d'électrode positive qui contient un oxyde composite de lithium-nickel qui est représenté par LiaNibM1-bO2 (où M représente au moins un élément choisi dans le groupe constitué par Na, Mg, Sc, Y, Mn, Fe, Co, Ni, Cu, Zn, Al, Cr, Pb, Sb et B ; 0,95 < a ≤ 1,2 ; et 0,8 ≤ b ≤ 1). La solution électrolytique contient un composé ester C d'un composé d'alcool A et d'un composé d'acide carboxylique B ; et le composé d'alcool A et/ou le composé d'acide carboxylique B est contenu dans une quantité de 15 ppm ou plus par rapport à la masse de la solution électrolytique.
(JA) 正極、セパレータ、セパレータを介して正極と対向する負極、および、溶媒と電解質とを含む電解液、を有する非水電解質二次電池であって、正極が、LiNi1-b(Mは、Na、Mg、Sc、Y、Mn、Fe、Co、Ni、Cu、Zn、Al、Cr、Pb、SbおよびBよりなる群から選択された少なくとも1種であり、0.95<a≦1.2であり、0.8≦b≦1である。)で表されるリチウムニッケル複合酸化物を含有する正極材料を含む。電解液が、アルコール化合物Aとカルボン酸化合物Bとのエステル化合物Cを含有し、且つ、アルコール化合物Aおよびカルボン酸化合物Bの少なくともいずれかを電解液の質量に対して15ppm以上含有する。
