Sintesis Elektroda Karbon Superkapasitor Dari Cangkang Akasia (Acacia Pods) Dengan Variasi Aktivator Kimia

---

Acacia pods is one of the biomass wastes that can be used as a basic material for porous activated carbon sources for supercapacitor carbon electrode materials. The supercapacitor carbon electrode from acacia pods waste is produced through the precarbonization stage, chemical activation using variations of KOH activators, ZnCl2, and without activation, where samples are coded AP-K, AP-Z, and AP-TA respectively. Furthermore, the carbonization process and physical activation were carried out which were flowed by N2 gas with a temperature of 600 ° C and CO2 with a temperature of 850 ° C. The activated carbon obtained is then characterized by its physical and electrochemical properties through density analysis, X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) N2 Gas Absorption, Cyclic Voltammetry (CV), and Galvanostatic Charge-Discharge (GCD). The resulting characterization results show a hierarchical pore structure supported by a high carbon content of 93,19%. Furthermore, the results of measuring electrochemical properties obtained the highest specific capacitance values in AP-Z samples, namely 282 F / g and 348,029 F / g. Based on these results, the AP-Z sample confirms optimum conditions for providing a carbon electrode based on acacia pods waste, potentially being used as a carbon electrode for supercapacitor applications.

Keywords: acacia pods, chemical activator, activated carbon, supercapacitor electrode electrochemistry.
