Аннотация
This study investigates the electrochemical performance of activated carbon (AC) derived from two biomass sources, rice husk (RH) and walnut shell (WS), utilizing two activation methods: chemical activation with potassium hydroxide (KOH) and physical activation with carbon dioxide (CO2). The aim is to evaluate the potential of these bio-derived carbon materials in energy storage applications, particularly for supercapacitors. The electrochemical behavior of the activated carbon electrodes was assessed using cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) techniques, along with electrochemical impedance spectroscopy (EIS), to evaluate the specific capacitance, energy density, charge transfer resistance, and ion diffusion properties.
