Lithium-rich manganese based layered oxide yLi2MnO3(1-y)LiMO2 (M=Ni, Co and Mn) is one of the candidate materials for high-capacity cathodes in next-generation lithium-ion batteries. Ion doping with cation and introducing oxygen vacancy are regarded as two methods to change the electrochemical performance of Li-rich cathode materials. In this work, Li1.2Mn0.54Co0.13Ni0.13O2 was synthesized via one-step co-precipitation process, ion doping with low cost element Cu as well as high-pressure torsion were carried out to modify the Li-rich material. Results show that doping with Cu can slightly improve the specific discharge capacity as well as the coulombic efficiency which may be attributed to the lower cation mixing degree.
