Abstract

See full text

A method for making a cathode active material of a lithium ion battery is disclosed. In the method, LiMPO4 particles and LiNPO4 particles are provided. The LiMPO4 particles and LiNPO4 particles both are olivine type crystals belonged to a pnma space group of an orthorhombic crystal system, wherein M represents Fe, Mn, Co, or Ni, N represents a metal element having a +2 valence, and N is different from M. The LiMPO4 particles and the LiNPO4 particles are mixed together to form a precursor. The precursor is calcined to form LiMxN1-xPO4 particles, wherein 0
