Supercapacitor is a storage device consisting of carbon electrodes, separator and electrolyte and current colector. In this research, carbon electrodes were made from young coconut fiber biomass with variations in KOH mass ratio of 1:0.20; 1:0.25 and 1:0.30 have been successfully prepared. The carbonization temperature and activation temperature are 550˚C and 750˚C respeetively. Carbon el…
