Activated carbon electrodes based on cassava petiole wastes have been successfully made using a different ZnCl2 activator concentration. The synthesis was started with the pre-carbonization process at 250°C and was followed by the grinding of the sample. Pre-carbonized samples were chemically activated at concentrations of 0.5 M, 0.7 M and 0.9 M. The activated carbon powder was converted into monolith form using Hydraulic Press and then followed by carbonization and physical activation process using a furnace at range of 600-900°C. Carbon electrodes were characterized by physical i.e density, degree of crystallinity, surface morphology, composition of elemental content, pore distribution and specific surface area. The electrochemical characterization i.e specific capacitance, energy density and power density. Characterization of the physical and electrochemical properties of the activated carbon electrodes showed significant results. All carbon electrodes showed amorphous properties with a surface area of 495-632 m2/g. Supercapacitor cells exhibit specific capacitance of 152.49 F/g, 193.68 F/g and 186.15 F/g for CP-0.5, CP-0.7 and CP-0.9 samples, respectively. The optimum concentration of ZnCl2 activator for producing carbon electrodes derived from cassava petiole waste was found at 0.7 M. This concentration was exhibited high specific capacitance, energy density and power density of 193.68 F/g, 26.90 Wh/kg and 96.94 W/kg, respectively.
