Because of the sustainability, cost-effectiveness, and simplicity fabrication meso/microporous carbon synthesized from various precursors, including plants, production, application biomass-derived in energy storage have piqued interest researchers. A chemical activation technique involving KOH carbonization at 600 °C inert gas was used to successfully synthesize activated carbons (AC) derived willow catkin (WC). The AC sample characterized using X-ray diffraction patterns (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), Energy dispersive (EDX), Transmission (TEM). In 3M aqueous electrolyte, cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), electrochemical impedance (EIS) were employed elucidate performance electrode. electrode has a specific capacitance 105 F. g-1 exhibited good cycling stability with retention 89.23% after 1000 cycles. prepared is as an material for supercapacitor.
