Abstract
A method for making a cathode composite material of a lithium ion battery is disclosed. In the method, a composite precursor is formed. The composite precursor includes a cathode active material precursor and a coating layer precursor coated on a surface of the cathode active material precursor. The composite precursor is reacted with a lithium source chemical compound, to lithiate both the cathode active material precursor and the coating layer precursor in the composite precursor.
