Supercapacitors are energy storage devices that have many advantages, including rapid charging and an unlimited lifespan. This research aims to evaluate the potential of papaya stem bark biomass (KBP) as a raw material ...

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, ...
