Li1.18Ni0.15Co0.15Mn0.52O2, a lithium-rich manganese oxygen cathode material , was successfully generated with the sol-gel methods, then we modified it using Ce4+ and obtained a new Li1.18Ni0.15Co0.15Mn0.52-xCexO2 (x=0, 0.01) material. scanning electron microscopy (SEM) and X-ray diffraction (XRD) testing were used to analysis the materials, and electrochemical properties were explored by constant current charge/discharge and cyclic voltammetry (CV) tests. Test results showed that cerium-doped cathode material maintained its lamellar structure without significant changes in microscopic morphology. It was also found that the capacity retention rate of the doped materials was 89% after 50 cycles at 0.2C, while that of the undoped materials were 77%. In addition, the discharge capacity of the doped materials at 0.2, 0.5, 1, 2.5, 5 and 10C is higher than that of the undoped materials. The above results show that Ce4+ doping can improve the Electrochemical performance of Li-rich Mn-based cathode materials .
