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.
