CATHODE COMPOSITE MATERIAL AND LITHIUM ION BATTERY USING THE SAME

摘要

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 spinel type lithium manganese oxide. The coating layer comprises 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.
