CA 2658860

A positive electrode of a nonaqueous electrolyte solution secondary battery comprises (A) a lithium-manganese composite oxide and (Bl) at least one lithium-nickel composite oxide which has a specific surface area X of 0.3 <= X(m2/g) and which is selected from a group consisting of LiNiO2, and LiNi1-x M x O2 (0 < × 0.5 is satisfied, and M represents at least one metal element selected from a group consisting of Co, Mn, Al, Fe, Cu and Sr), whereby it is possible to obtain a nonaqueous electrolyte solution secondary battery which is superior in battery properties, especially charge and discharge cycle properties, retention properties and safety.

Une électrode positive d'une pile secondaire comportant une solution électrolytique non aqueuse comprend : (A) un oxyde composite lithium-manganèse; (B) au moins un oxyde composite lithium-nickel ayant une surface spécifique X de 0,3 X(m2/g) choisi parmi les suivants : LiNiO2 et LiNi1-x M x O2 (où la condition 0 < x 0,5 satisfaite, et M représente au moins un élément métallique parmi les suivants : Co, Mn, Al, Fe, Cu et Sr); elle permet d'obtenir une pile secondaire à solution électrolytique non aqueuse possédant des propriétés supérieures, surtout en ce qui concerne le cycle charge-décharge, les propriétés de rétention ainsi que la sécurité.
