ABSTRACT
Supercapacitor is an electrochemical energy storage devices that can provide a higher energy density than conventional dielectric capacitors. The most important component of a supercapacitor cell is the electrodes. In this research, the supercapacitor cell electrodes used are based on young coconut fiber with carbonization temperature variations of 500°C, 600°C and 700°C. The pre-carbonization process is operated using a temperature of 200°C for 90 minutes, chemical activation using an ZnCl2 0.5 M activating agent, the carbonization using N2 gas with various temperatures and physical activation using CO2 gas at 800°C. Characterization of the physical properties of Carbon electrodes uses the method of calculating Density, Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Energy Dispersive X-Ray (EDX). Characterization of electrochemical properties of supercapacitor cells using Cyclic Voltammetry (CV) methods. The highest density value is the CNL-600 sample with a density loss percentage value of 50.96%. Microstructural analysis shows that the Carbon electrode is semicrystalline as indicated by the presence of two sloping peaks at an angle of 2θ around 24° and 45°. Analysis of the physical properties of activated Carbon electrodes for the application of young coconut fiber-based supercapacitor cells showed that samples with a carbonization temperature of 600°C are the best samples, characterized by a Lc/La ratio of 0.8041 with an average number of microcrystalline inner layers of around 2.872, with a size pore diameter of 22.7 nm and a percentage of carbon content of 91.89. Analysis of electrochemical properties showed that samples with a carbonization temperature of 600°C had the highest specific capacitance values, namely 190.3 F/g using the CV method.
