NOVELTY - A negative electrode-regulated nonaqueous electrolyte secondary battery (30) has a negative electrode (1), a positive electrode (2) having positive electrode active material layer containing lithium-nickel composite oxides (I and II), a separator (3) interposed between the positive electrode and negative electrode, and a non-aqueous electrolyte, and stops charging by the voltage drop of electrode (1). In the nonaqueous electrolyte secondary battery, the size of negative electrode active material layer is more than the size of positive electrode active material layer.    USE - Nonaqueous electrolyte secondary battery e.g. lithium-ion secondary battery is used for small portable apparatus, electric power storage installation, and hybrid electric vehicle.    ADVANTAGE - The nonaqueous electrolyte secondary battery has excellent cycle characteristics and capacitance.    DETAILED DESCRIPTION - A negative electrode-regulated nonaqueous electrolyte secondary battery has a negative electrode having a negative electrode active material layer, a positive electrode having a positive electrode active material layer, a separator interposed between the positive electrode and the negative electrode, and a non-aqueous electrolyte, and stops charging by the voltage drop of the negative electrode. In the nonaqueous electrolyte secondary battery, the size of the negative electrode active material layer is more than the size of the positive electrode active material layer. The positive electrode active material layer contains a lithium-nickel composite oxide of formula: LiNixM1-xO2 (I) and LiNix'Coy'M'1-x'-y'O2 (II), where x is 0.7-1 (excluding 1), M is metal, x' is 0-0.5 (excluding 0), y' is 0-1 (excluding 0 and 1), and M' is metal excluding cobalt.
