AbstractSupercapacitors with nanostructured activated carbon electrodes from natural precursors have sparked huge attention due to its great stability of cycle as well as low cost and excellent performance. In this study, activated carbon was produced from desiccated coconut residue by chemical activation with KOH. The supercapacitor was characterized in a supercapacitor configuration by cyclic voltammetry and charge-discharge with potential window of 1V and current loads of 1A/g. Supercapacitor electrodes prepared from desiccated coconut residue exhibited excellent specific capacitance of 83 F/g.
