PROBLEM TO BE SOLVED: To provide a new process of manufacturing a positive electrode active material containing carbon coated lithium iron silicate.SOLUTION: The process of manufacturing a positive electrode active material for a lithium ion battery includes: mixing by using a ball mill, olivine silicate compound fine particles containing a transition metal (M) (M represents Fe, Ni, Co, Al, Zn, V, Zr, or Mn. However, not containing lithium iron silicate.), a conductive carbon material, and a dispersion liquid containing a solvent soluble organic compound and a solvent; drying; and then calcinating. |
