英文摘要	In this work, fluoroethylene carbonate (FEC) is used as an additive to improve the interface stability between LiNi0.6Co0.2Mn0.2O2 (NCM622) electrode and electrolyte under high voltage (4.6V vs Li/Li+). The improved cycle stability and electrochemical impedance spectroscopy (EIS) studies imply the formation of robust, uniform and less-resistive film on the surface of NCM622. The results from TEM, SEM and XPS demonstrate that FEC facilitates the formation of CEI layer, and the FEC-derived CEI protects against not only the decomposition of the electrolyte solvent but also oxidation of the NCM622 electrode.
