Title (EN) LITHIUM-NICKEL COMPOSITE OXIDE, PROCESS FOR PREPARING THE SAME, AND POSITIVE ACTIVE MATERIAL FOR SECONDARY BATTERY
(FR) OXYDE COMPOSITE LITHIUM-NICKEL, SON PROCEDE DE PREPARATION, ET MATERIAU ACTIF POSITIF DESTINE A UNE BATTERIE SECONDAIRE
Abstract:
(EN) A positive active material for secondary batteries, comprising a lithium-nickel composite oxide represented by the general formula: Liy-x1Ni1-x2MxO2 (wherein M represents an element selected from the group consisting of: Al, Fe, Co, Mn and Mg, x = x1 + x2, 0 $m(F) x1 < 0.2, 0 < x2 $m(F) 0.5, 0 < x $m(F) 0.5, and 0.9 $m(F) y $m(F) 1.3), wherein the crystals have been satisfactorily developed and are highly pure and the stability of high discharge capacity is excellent.
(FR) Ce matériau actif positif, destiné à des batteries secondaires, comprend un oxyde composite lithium-nickel représenté par la formule générale Liy-x1Ni1-x2MxO2 où M représente un élément choisi dans le groupe composé de Al, Fe, Co, Mn et Mg, x = x1 + x2, 0 $m(F) x1 < 0,2, 0 < x2 $m(F) 0,5, 0 < x $m(F) 0,5, et 0,9 $m(F) y $m(F) 1,3. Ses cristaux sont développés de façon satisfaisante et de haute pureté, et il présente une stabilité excellente en cas de décharge.
