(JA) 非水電解質二次電池用正極活物質、及び非水電解質二次電池
Abstract:
(EN) Provided is a positive-electrode active material for a non-aqueous electrolyte secondary battery, said positive-electrode active material being represented by the compositional formula LixNiyCoαAlβSizO2-γ (in the formula, x, y, α, β, z, and γ respectively satisfy 0.95
(FR) La présente invention concerne un matériau actif d'électrode positive pour une batterie rechargeable à électrolyte non aqueux, ledit matériau actif d'électrode positive étant représenté par la formule de composition LixNiyCoαAlβSizO2-γ (dans la formule, x, y, α, β, z et γ satisfont respectivement 0,95 < x < 1,05, 0,80 < y < 1, 0 < α < 0,15, 0 < β < 0,05, y + α + β = 1, 0 < z ≤ 0,02 et 0 ≤ γ < 0,05 qui spécifient leurs plages), et ayant une structure cristalline stratifiée appartenant au groupe spatial R - 3 m. De plus, le matériau actif d'électrode positive comprend un oxyde stratifié satisfaisant la relation 0,28° ≤ n ≤ 0,50°, n étant la largeur de demi-valeur du pic de diffraction du plan (211) dans une figure de diffraction des rayons X.
(JA) 非水電解質二次電池用正極活物質であって、組成式LiNiCoαAlβSi2-γ(式中、x、y、α、β、z及びγはそれぞれ特定の範囲に含まれる0.95<x<1.05、0.80<y<1、0<α<0.15、0<β<0.05、y+α+β=1、0<z≦0.02、及び0≦γ<0.05を満たす。)で表され、空間群R-3mに属する層状結晶構造を有する。さらに、X線回折パターンにおける(211)面の回折ピークの半値幅nが0.28°≦n≦0.50°である層状酸化物を含む。
