Pengaruh Larutan Elektrolit Terhadap Kinerja Superkapasitor Dari Biomassa Pel…

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 …
