A method for making a cathode composite material is disclosed. In the method, a maleimide-based material is provided. The maleimide-based material is a maleimide monomer, a maleimide polymer formed from the maleimide monomer, or combinations thereof. The maleimide-based material, an inorganic electrical conductive carbonaceous material, and a cathode active material are mixed to form a mixture. The mixture is heated to a temperature of about 200° C. to about 280° C. in a protective gas to obtain the cathode composite material. A cathode composite material and a lithium ion battery are also disclosed. |
