Abstract


Supercapacitors areenergy storage devices consisting of electrodes, electrolytes, current collectors, and separators. Supercapacitor cells have components called electrodes. In this study, the basic material used to make supercapacitor cell electrodes is young coconut fiber with variations in physical activation temperature of 700°C, 750°C and 800°C. The process of preparing of supercapacitor cell electrodes begins with pre-carbonization using an electric oven, chemical activation using 0.5M KOH activator, carbonization process using N2 gas at a temperature of 600°C and physical activation using CO2 gas. Analysis of the  supercapacitor cell electrodes made from young coconut coir showed that the sample with a physical activation temperature of 750°C was the best sample, indicatedby a low density value of 0.68 g/cm3andthe highest specific capacitance of 225.1736 F/g which was tested using Cyclic Voltammetry method.
