| description | To provide a cathode active material for a lithium ion secondary battery excellent in the cycle characteristics and rate characteristics even when charging is conducted at a high voltage. A cathode active material for a lithium ion secondary battery, which comprises particles (III) having a covering layer comprising a metal oxide (I) containing at least one metal element selected from the group consisting of Al, Y, Ga, In, La, Pr, Nd, Gd, Dy, Er and Yb, and a compound (II) containing Li and at least one non-metal element selected from the group consisting of S and B, on the surface of a lithium-containing composite oxide, wherein the atomic ratio (the non-metal element/the metal element) contained within 5 nm of the surface layer of the particles (III) is within a specific range. |
