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.

Method for making cathode composite material for lithium ion batteries

A cathode composite material includes a cathode active material and a coating layer coated on a surface of the cathode active material. The cathode active material includes a lithium cobalt oxide. The coating layer includes a lithium metal oxide having a crystal structure belonging to C2/c space group of the monoclinic crystal system. The present disclosure also relates to a lithium ion battery including the cathode composite material.
