Abstract:
(EN) Provided is a manganese nickel composite hydroxide which serves as a starting material for positive electrode active materials for secondary batteries, and which enables the achievement of an excellent secondary battery having low resistance and high output characteristics. A manganese nickel composite hydroxide according to the present invention is represented by general formula (A) Mn1-x-yNixMy(OH)2+α (wherein 0 ≤ x ≤ 0.27, 0 ≤ y ≤ 0.05, 0 ≤ α ≤ 0.5, and M represents at least one element selected from among Mg, Al, Ca, Ba, Sr, Ti, V, Fe, Cr, Co, Cu, Zr, Nb, Mo and W), and has an SO4 content of 0.90% by weight or less, an Na content of 0.04% by weight or less, a BET specific surface area of from 40 m2/g to 70 m2/g (inclusive), and a value obtained by [(d90 - d10)/(average particle diameter)] of 0.90 or less, said value being an index indicating the expanse of the particle size distribution.
(FR) L'invention concerne un hydroxyde composite de manganèse et de nickel qui sert de matériau de départ pour des matériaux actifs d'électrode positive destinés à des batteries secondaires, et qui permet l'obtention d'une excellente batterie secondaire présentant des caractéristiques de faible résistance et de sortie élevée. Un hydroxyde composite de manganèse et de nickel selon la présente invention est représenté par la formule générale (A) Mn1-x-yNixMy(OH)2+α (dans laquelle 0 ≤ x ≤ 0,27, 0 ≤ y ≤ 0,05, 0 ≤ α ≤ 0,5, et M représente au moins un élément choisi parmi le Mg, l'Al, le Ca, le Ba, le Sr, le Ti, le V, le Fe, le Cr, le Co, le Cu, le Zr, le Nb, le Mo et le W), et a une teneur en SO4 de 0,90 % en poids ou moins, une teneur en Na de 0,04 % en poids ou moins, une surface spécifique BET de 40 m2/g à 70 m2/g (inclus), et une valeur obtenue par [(d90 - d10)/(diamètre moyen des particules)] de 0,90 ou moins, ladite valeur étant un indice indiquant l'étendue de la distribution granulométrique.
(JA) 低抵抗であり、また高出力特性を有する優れた二次電池を実現することができる二次電池の正極活物質の原料となるマンガンニッケル複合水酸化物を提供する。 本発明に係るマンガンニッケル複合水酸化物は、一般式(A):Mn1-x-yNi(OH)2+α(0≦x≦0.27、0≦y≦0.05、0≦α≦0.5、Mは、Mg、Al、Ca、Ba、Sr、Ti、V、Fe、Cr、Co、Cu、Zr、Nb、Mo、Wから選択される少なくとも1種の元素)で表され、SOの含有量が0.90重量%以下、及びNaの含有量が0.04重量%以下であり、BET比表面積が40m/g以上70m/g以下であり、粒度分布の広がりを示す指標である〔(d90-d10)/平均粒径〕により求められる値が0.90以下である。
