ELECTROCHEMICAL BEHAVIOUR AND PERFORMANCE OF FLEXIBLE GRAPHITE YARNS IN DIFFERENT ELECTROLYTES WITH WIDE POTENTIAL WINDOW OF 2 V

Abstract

Energy storage systems have received increasing attention in recent years because of the requirements of energy supply with respect to the growing population and technology. Among the technologies of energy storage devices, supercapacitors become popular due to their superior characteristics such as high power density, extremely fast charge-discharge capability and long life cycle. A wide variety of materials are already in use to fabricate supercapacitors. Carbon and its derivatives are common materials among the electrode materials of supercapacitors. In this study, electrochemical behaviour of flexible graphite yarns are investigated in different media in order to elucidate the performance of graphite as a supercapacitor material. Electrochemical experiments of graphite electrode are carried out in sodium sulphate (Na2SO4), hydrochloric acid (HCl), potassium hydroxide (KOH) and Ethaline deep eutectic solvent as electrolyte media. Graphite yarn is cycled at wide potential window (from -1 V to 1 V) at various scan rates in the range of 5 to 100 mV s−1 in order to observe the associated electrochemical behaviour and performance. Graphite yarn electrodes without any treatment can be used in Ethaline and aqueous Na2SO4 electrolytes. However, these electrodes cannot be used in acidic or alkaline media with high potential window of 2 V.
