In this study, 3 different materials were combined to form hybrid nanocomposite for SupercapBattery applications. Reduced graphene oxide (rGO), iron (III) oxide (Fe2O3), and poly(3,4- ethylenedioxythiophene) (PEDOT) were used as a component of nanocomposites. Electrochemical performances were performed by cyclic voltammetry (CV), galvanostatic charge / discharge (GCD) and electrochemical impedance spectroscopy (EIS) measurements. EIS measurements were analyzed by Nyquist, Bode-magnitude, Bode-phase, and Admittance plots. Long-term stability tests were obtained by CV method using 1000 charge/discharge performances at a scan rate of 100 mV×s-1 . The highest specific capacitance was calculated as Csp= 1129.38 F×g-1 at 2 mV×s-1 (electrode weight was obtained as 15,7 mg).
