Abstract
Provided herein are positive electrode active substance particles comprising a lithium nickelate composite oxide which have a high energy density and are excellent in repeated charge/discharge cycle characteristics when charging at a high voltage, as well as a non-aqueous electrolyte secondary battery. The positive electrode active substance particles herein can each comprise a core particle X comprising a lithium nickelate composite oxide having a layer structure which is represented by the formula: LiNiCOMO, as defined herein; and a coating compound Y comprising at least one element selected from the group consisting of Al, Mg, Zr, Ti and Si and having an average film thickness of 0.2 to 5 nm, in which a crystal phase having a layered rock salt structure and comprising Niions is present in the form of a layer between the core particle X and the coating compound Y.
