Implementing Conducting Polymers And Activated Carbon, Electrochemically Characterising Asymmetrical Supercapacitors: Cyclic Voltammetry, Frequency Response Analysis, And ESR Investigation

Abstract

Due to its high power density, lengthy cycle life, and quick charge-discharge characteristics, supercapacitors have attracted a lot of attention as energy storage devices. Asymmetrical supercapacitors have become interesting prospects for a range of uses because they use varied electrode materials for better performance. In this paper, we give a thorough investigation of an asymmetrical supercapacitor that uses electrodes made of activated carbon and conducting polymers. Cyclic voltammetry (CV), frequency response analysis (FRA), and electrochemical impedance spectroscopy (ESR) were used to assess the device's performance. The findings offer important new understandings of the supercapacitor system's electrochemical behaviour, energy storage capability, and charge transport processes.
