Pengaruh Larutan Elektrolit Terhadap Kinerja Superkapasitor Dari Biomassa Pelepah Daun Pinang

---

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%. The FTIR results show that the carbon electrode has O-H, C-H, C=O, and C=C functional groups. XRD test results show that the carbon electrode is amorphous. Analysis of electrochemical properties using cyclic voltammetry and galvanostatic charging and discharging showed that the highest specific capacitance values were produced by samples with H2SO4 electrolyte of 182 Fg-1 and 192 Fg-1, respectively. This study shows that the H2SO4 electrolyte is the best electrolyte to obtain high capacitance values and betel leaf midrib biomass which has the potential to be used as carbon electrodes for supercapacitor cell applications.
