摘要： The anode of a nonaqueous electrolyte secondary cell contains (A) a lithium-manganese compound oxide and (B1) a lithium-nickel compound oxide having a specific surface area X of below 0.3 (m2/g) and consisting of at least one kind selected from among the group consisting of LiNiO¿2?, Li2NiO2, LiNi2O4, Li2Ni2O4, and LiNi1-xMxO2 (0∫x≤0.5, and M represents at least one metallic element selected from among the group consisting of Co, Mn, Al, Fe, Cu, and Sr). Such a nonaqueous electrolyte secondary cell is excellent in cell characteristics, and especially charging/discharging cycle characteristic, storage characteristic, and safety.
