Abstract: front page image
(EN)Disclosed is a positive electrode active material for a non-aqueous electrolyte secondary battery, which comprises a lithium-containing transition metal oxide having an oxygen cubic close-packed structure, wherein the lithium-containing transition metal oxide has a chemical composition represented by formula (1). Li[Lip(NixMnyCoz)1-p]O2 wherein x, y and z represent the ratio among the elements nickel, manganese and cobalt, respectively; and x, y, z and p fulfill the requirements represented by the following formulae: 0.2+y≤x≤0.7, 0.15≤y, 0.05≤z, x+y+z=1 and 0≤p≤0.1.
(FR)L'invention concerne un matériau actif d'électrode positive pour batterie secondaire à électrolyte non aqueux renfermant un oxyde de métal de transition contenant du lithium dont les atomes d'oxygène forment une structure compacte cubique, la composition chimique dudit oxyde de métal de transition contenant du lithium étant représentée par la formule (1). Li[Lip(NixMnyCoz)1-p]O2 dans laquelle x, y et z représentent respectivement l'indice des éléments nickel, manganèse et cobalt, et x, y, z et p sont définis par les formules suivantes : 0,2 + y ≤ x ≤ 0,7, 0,15 ≤ y, 0,05 ≤ z, x + y + z = 1 et 0 ≤ p ≤0,1.
(JA) 酸素の立方最密充填構造を有するリチウム含有遷移金属酸化物を含み、前記リチウム含有遷移金属酸化物の組成が、式(1):Li[Lip(NixMnyCoz1-p]O2  で表され、x、yおよびzはそれぞれニッケル、マンガンおよびコバルトの元素比率を表し、0.2+y≦x≦0.7、0.15≦y、0.05≦z、x+y+z=1および0≦p≦0.1である、非水電解質二次電池用正極活物質。
