Abstract
A positive electrode active material for a non-aqueous secondary battery having high capacity and high rate characteristics is intended to be provided. Further, a positive electrode for a non-aqueous secondary battery and a non-aqueous secondary battery are intended to be provided by using the positive electrode active material. The positive electrode active material for the non-aqueous secondary battery contains a lithium composite oxide having an olivine structure represented by the chemical formula: LiMnM(PO)in which A>0, B>0, M represents a metal element, M in the chemical formula is one or more metal elements selected from Fe, Ni, Co, Ti, Cu, Zn, Mg, V, and Zr, the ratio A/B in the chemical formula is within a range of: 2<A/B≦7, and the value of X is within a range of: 0.3≦X<1.
