dc.description.abstractIn this study, the ability of Poly (3,4-ethylenedioxythiophene)/electrochemically reduced graphene oxide (PEDOT/ERGO) electrodes for supercapacitors to store electrical energy is studied. PEDOT/ERGO electrodes are produced using a simple two-step electrochemical method that involves electrochemically reduction of graphene oxide, and then PEDOT is electrochemically deposited onto the ERGO in different electrolyte solutions. Electrochemical techniques such as cyclic voltammetry (CV), galvanostatic charge discharge (GCD), and electrochemical impedance spectroscopy (EIS) are utilized to investigate the electrochemical characteristics of PEDOT/ERGO electrodes produced in different electrolyte systems including 0.1 M lithium perchloride/acetonitrile (LiClO4/ACN), tetraethylammoniumtetrafluoroborate/acetonitrile (Et4NBF4/ACN), and tetrabutylammonium hexaflorophosphate/acetonitrile (Bu4NPF6/ACN). The electrolyte type has a significant impact on electrochemical results. PEDOT/ERGO manufactured in LiClO4/ACN demonstrates a high specific capacitance (Csp) and low charge transfer resistance (Rct). According to results, the Csp value is decreased in the following order; 26.48 mFcm-2 for LiClO4, 20.58 mFcm-2 for Et4NBF4, 8.96 mFcm-2 for Bu4NPF6.
