    摘要： A positive electrode active material, which gives a non-aqueous electrolyte secondary battery capable of high input/output where resistance due to a battery reaction in a low temperature environment is suppressed, is produced by a method comprising: (a)providing a nickel hydroxide which is represented by the general formula Ni1−(x+y)CoxMy(OH)2, (b)heating the nickel hydroxide at a temperature not lower than 600° C. and not higher than 1000° C. to produce a nickel oxide which is represented by the general formula Ni1−(x+y)CoxMyO; and (c)mixing the nickel oxide and a lithium compound to obtain a mixture and heating the mixture at a temperature not lower than 700° C. and not higher than 850° C. to produce a lithium-containing composite oxide which is represented by the general formula LiNi1−(x+y)CoxMyO2, where 0.1≦x≦0.35 and 0.03≦y≦0.2 are satisfied and M is at least one selected from the group consisting of Al, Ti and Sn.

    摘要： To improve high temperature storage characteristic of a non-aqueous electrolyte secondary battery suitable for high input/output application, the structure of a positive electrode active material is optimized. The non-aqueous electrolyte secondary battery includes a positive electrode; a negative electrode; a separator interposed between the positive and negative electrodes; and a non-aqueous electrolyte. The positive electrode active material includes secondary particles, each formed of an aggregate of primary particles. A value (VPr) defined by the formula: VPr=(1−C/D)/(A2×B3) is not less than 0.0005 and not greater than 0.04, where an average particle size of the primary particles is A μm, an average particle size of the positive electrode active material is B μm, a tap density of the positive electrode active material is C g/ml, and a true specific gravity of the positive electrode active material is D g/ml.
