PEMBUATAN ELEKTRODA KARBON SUPERKAPASITOR DARI BIOMASSA PELEPAH DAUN PINANG

Abstract

In this study, supercapacitor electrodes were synthesized from areca leaf midrib biomass as a renewable carbon source. The process of making this supercapacitor cell electrode is through a pre-carbonization process, chemical activation, chemical carbonization in N2 gas and physical activation using CO2 gas. Analysis of the physical properties of the carbon electrodes showed that the sample had a density value of 0.637 g/cm3 or a percentage decrease of 36.55%. This study shows that betel leaf midrib biomass which has the potential to be used as carbon electrodes for supercapacitor cell applications.
