Abstract (300 words maximum)
Electrochemical energy storage involves the conversion between electrical energy and chemical energy, which is based on electrochemical reactions that occur at the interface between two materials, typically an electrode and an electrolyte. The increase in energy demands and the environmental consequences of using fossil fuels has become an ever-expanding concern. Electrochemical storage systems have provided a possible solution through the use of supercapacitors devices. In this work, a nanocomposite electrode using graphene oxide and polypyrrole (GO/PPy) was synthesized using electropolymerization processes. Synthesized GO/PPy films are used as electrodes for the application of supercapacitors to study the effects of graphene oxide on polypyrrole and its performance. Electrochemical methods such as cyclic voltammetry (CV) and Electrochemical Impedance Spectroscopy (EIS) are used to evaluate the electrode performance. Various performance matrices such as energy storage capacities, ohmic resistance, non-ohmic resistance, and Warburg resistance, which reflect the charge transport and charge storage behavior, will be discussed.
