摘要
Electrochemical properties of a natural graphite anode in ionic liquid and organic electrolytes was comparatively investigated. The results reveal that the organic cation reversibly inserted into and deinserted from graphene interlayer. The addition of chloroethylenene carbonate(Cl-EC) resulted in significant electrochemical enhancement. The mechanisms responsible for the electrochemical enhancement were discussed through ac impedance, SEM, and FTIR measurements.

The results reveal that the organic cation reversibly inserted into and deinserted from graphene interlayer. The addition of chloroethylenene carbonate （C1-EC） resulted in significant electrochemical enhancement. through ac impedance, The mechanisms responsible for the electrochemical enhancement were discussed SEM, and FTIR measurements.
