Zusammenfassung:Renewable porous carbon from lignocellulose material as the basic material for supercapacitors is of great interest to researchers because of its high application potential while solving environmental problems. Biomass-based lignocellulose components are the main choice because of the extraordinary impact on the carbon structure they get. Here, the identification of the potential of lignocellulose biomass from mangosteen cultivars as source material for electrode materials for supercapacitors has been studied on their electrochemical behaviour. The electro-physico-chemical features are reviewed in detail through cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) analysis at different ranges of scan rates and current densities. The obtained electrode was prepared by adding 10% polyvinyl alcohol binder to 0.7 gr carbon powder. The supercapacitor cell design is prepared in a symmetrical shape bounded by an organic separator. In general, the electrochemical properties of the electrode materials that have been obtained confirm the normal electrical double-layer capacitor features with an indication of the presence of apparent capacitance. The highest specific capacitance was 153.31 at 1 A g −1 . Furthermore, the energy output was recorded of 1.67 Wh kg −1 . These results confirm that an electrochemical study of mangosteen peel-based carbon materials has been successfully carried out for supercapacitor energy storage applications.
