Abstract:
The purpose of the present invention is to provide a positive-electrode active material for non-aqueous electrolyte secondary batteries that is capable of achieving both a high capacity and a high output. This positive-electrode active material contains a lithium-nickel composite oxide represented by the general formula: Li b Ni 1-x-y Co x M y O 2  wherein M represents at least one element selected from Al, Ti, Mn and W, b is 0.95≤b≤1.03, x is 0<x≤0.15, y is 0<y≤0.07, and x and y is x+y≤0.16, wherein c-axis length of the lithium-nickel composite oxide is 14.185 angstrom or greater as determined by a Rietveld analysis of X-ray diffraction.

Claim (Index 8):
The process for producing a positive electrode active material for a non-aqueous electrolyte secondary battery according to  claim 6 , wherein said nickel composite hydroxide is prepared by adding dropwise an aqueous solution comprising nickel sulfate and a metal compound comprising cobalt and at least one element selected from the group consisting of Al, Ti, Mn and W, and an aqueous solution comprising a compound for supplying ammonium ion to a reaction solution in a reaction vessel being heated, and wherein an aqueous solution of an alkali metal hydroxide is added dropwise to the reaction solution so that alkalinity of the reaction solution is maintained during the preparation of the nickel composite hydroxide.
