A cathode active material for a non-aqueous electrolyte secondary battery comprises a lithium-containing composite oxide powder, which is represented by the formula LipNxMyOzFa wherein N is at least one element selected from the group consisting of Co, Mn and Ni, M is zirconium and optionally at least one element selected from the group consisting of Al, alkaline earth metal elements and transition metal elements other than the element N, 0.9≦̸p≦̸1.1, 0.965≦̸x≦̸1.00, 0≦̸y≦̸0.035, 1.9≦̸z≦̸2.1, x+y=1 and 0≦̸a≦̸0.02, an atomic ratio of zirconium/the element N is in a range of at least 1.0 to 4.0. A method to produce the cathode active material is provided. |
