Study on the Application of N,N′-1-Ethyl-4-Butyl, Triethylene and Diamine Hexafluorophosphate in Supercapacitors

Abstract:

An electrolyte, N,N′-1-ethyl-4-butyl, triethylene diamine hexafluorophosphate dissolved in glutaronitrile, was developed and investigated in a symmetrical supercapacitor using activated carbon as electrodes (active carbon/active carbon). The electrochemical erformance of the supercapacitor was examined using ac impedance and constant current charging/discharging tests. According to the results, its singleanode speciﬁc capacitance could reach 324.7 Fg−1. The supercapacitor also has better capacitance characteristics.
