The character of the solid electrolyte interface(SEI layer) on the surface of LiCoO2 formed in the electrolytes contained different salt such as LiPF6、LiClO4 and LiBF4 were studied in this paper.The results showed that the SEI film exists in all three electrolytes after the processes of charge and discharge.The morphological character and the formation voltage of the SEI layer of LiCoO2 were different in different electrolytes.The electrochemical performance of the battery such as reversible capacity,average discharge voltage and electrochemical impedance were affected significantly by SEI film formed in different electrolytes.
