The electrochemical performance of an Electrochemical Double Layer Capacitor consisted of higher specific surface area activated carbon and ionic liquid \CF3COO was investigated by constant current charge/discharge and cyclic voltammegrams(CV) methods.The results indicated that the \CF3COO had High specific capacitance,excellent cyclic characteristics and high charge/discharge efficiency.Specific capacitance of the EDLC increased with electrochemical window increase at the range of steady electrochemical window.Energy density increased with current and voltage increase,power density deduced with current increase but increased with electrochemical window increase.These conclusions revealed that the \CF3COO was very suitable for the electrolyte of EDLC.
