Title (EN) POSITIVE ELECTRODE ACTIVE MATERIAL FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY
(FR) MATÉRIAU ACTIF POUR ÉLECTRODE POSITIVE POUR DES BATTERIE SECONDAIRE À ÉLECTROLYTE NON AQUEUX
(JA) 非水電解質二次電池用正極活物質
Abstract:
(EN) Disclosed is a positive electrode active material for nonaqueous electrolyte secondary batteries which is composed of a complex oxide containing M1 and M2 (M1 is one or more elements selected from the group consisting of Li, Na and K, and M2 is one or more elements selected from the group consisting of Ni, Mn, Co, Fe, Ti, V and Cr). The primary particles of this complex oxide has an average diameter (DP) of not less than 0.1 μm and less than 3 μm, and the average particle diameter (DS) of the complex oxide is not less than 1 μm and not more than 10 μm. In addition, the value of DS/DP is not less than 2 but not more than 30.
(FR) La présente invention concerne un matériau actif pour électrode positive pour des batteries secondaires à électrolyte non aqueux qui est composé d’un oxyde complexe contenant M1 et M2 (M1 étant un ou plusieurs éléments sélectionnés parmi le groupe constitué de Li, Na, et K, et M2 étant un ou plusieurs éléments sélectionnés parmi le groupe constitué de Ni, Mn, Co, Fe, Ti, V et Cr). Les particules primaires de cet oxyde complexe présentent un diamètre moyen (DP) compris entre 0,1 µm et 3 µm, et le diamètre moyen de particule (DS) de l’oxyde complexe est compris entre 1 µm et 10 µm. En outre, la valeur de DS/DP est comprise entre 2 et 30.
(JA) 1およびM2(ただしM1はLi、NaおよびKからなる群より選ばれる1種以上の元素であり、M2はNi、Mn、Co、Fe、Ti、VおよびCrからなる群より選ばれる1種以上の元素である。)を含有する複合酸化物であって、複合酸化物の一次粒子径の平均値(DP)が0.1μm以上3μm未満の範囲であり、該複合酸化物の平均粒子径(DS)が1μm以上10μm以下の範囲であり、さらにDS/DPの値が2以上30以下の範囲である複合酸化物からなる非水電解質二次電池用正極活物質を提供する。
