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 …
