NOVELTY - A nonaqueous electrolyte battery has a cladding material, a negative electrode (4) having a collector and a negative electrode layer (4b), a positive electrode (3) having a collector and a positive electrode layer (3b), and a nonaqueous electrolyte. The positive electrode layer has positive electrode active material (a) containing layered lithium-nickel-cobalt-manganese complex oxide and positive electrode active material (b) comprising lithium-cobalt complex oxide.    USE - Nonaqueous electrolyte battery is used for battery pack for motor vehicle (both claimed) e.g. hybrid vehicle.    ADVANTAGE - The nonaqueous electrolyte battery has excellent cycling characteristics and suppressed gas evolution and swelling of cladding material.    DETAILED DESCRIPTION - A nonaqueous electrolyte battery has a cladding material, a negative electrode having a collector and a negative electrode layer formed on at least one surface of the collector, and accommodated in the cladding material, a positive electrode having a collector and a positive electrode layer formed on at least one surface of the collector, and accommodated in the cladding material, and a nonaqueous electrolyte. The negative electrode layer has negative electrode active material having lithium occlusion/release electric potential of 0.4 V or more. The positive electrode layer has positive electrode active material (a) containing layered lithium-nickel-cobalt-manganese complex oxide and positive electrode active material (b) comprising lithium-cobalt complex oxide which covered the surface of at least one portion with metallic compound. The volume of pores having diameter of 0.01-1 mu m of positive electrode layer obtained by mercury press-in method is 0.06-0.25 mL per 1 g of mass of positive electrode layer (excluding mass of collector). The pore surface area in pole volume range of pore diameter of 0.01-1 mu m obtained by mercury press-in method is 2.4-8 m2/g.
