Abstract

The electrochemical properties of composite material consisting of poly(3, 4-ethylenedioxythiophene) (pEDOT) and iron hexacyanocobaltate (FehcCo) have been investigated for supercapacitors' application. The composite material pEDOT/FehcCo was electrodeposited on titanium or carbon fabric substrate. Prepared electrodes were used in supercapacitors operating in nonaqueous electrolytes (1 M KPF6, 1 M LiPF6 in ethylene carbonate with dimethyl carbonate mixture of solvents). The capacitance values were estimated by galvanostatic and cyclic voltammetry techniques. The material was investigated in symmetric two-electrode cell configuration. The material pEDOT/FehcCo exhibits high capacitance values (~70 F cm-3) and a good cycling performance with a high stability in the tested electrolytes.
