【 摘 要 】

LiF was used to modify the Ni-rich ternary cathode materials in this paper through chemical reaction deposit and low temperature sintering. The microstructure of the materials was characterized by XRD and SEM. The electrochemical properties were inspected by Land test system. During the charge/discharge test under different concentrations of LiF modified ternary electrode materials, the electrochemical performance is superior to unmodified one. And the optimum modification ratio is 3%. From charge/discharge test, it can be seen that at 0.2C, Li1.04Ni0.6Co0.2Mn0.2O2 has initial discharge capacities of 179mAh/g under the 3% LiF modification ratio.
