Abstract

The increasing demand for renewable energy resources, supercapacitors are becoming important devices due to their high specific energy and specific power performance. This research focuses on using Kepayang leaves as a basic material for supercapacitor carbon electrodes. This research involves making active carbon from Kepayang leaves through a carbonization process at temperatures of 500, 600, 700, and 800 oC for 1 hour with chemical activation using ZnCl2. The characteristics carried out include density analysis, Fourier Transform Infra-Red (FTIR), X-ray diffraction (XRD), and Cyclic Voltammetry (CV). The density analysis results show that with every increase in temperature, the density decreases. Functional groups in the FTIR spectrum show that C bonds are formed, while XRD analysis shows an amorphous structure both before and after pyrolysis. The electrochemical properties of Kepayang leaf carbon show that the diffusion process is getting better as the carbonization temperature is higher. The highest specific capacitance obtained was based on the results of CV 91 F/g at a temperature of 700 oC.
