Year: 2024
Type: article
Abstract: The remarkable microstructural characteristics of porous carbons make them attractive as electrode materials for supercapacitors. The production of porous carbon from biowaste materials has gained considerable attention because of their affordability and natural abundance. This work approaches the preparation of porous carbon using the bark of wood apple tree precursor. The X-ray diffraction analysis, Fourier transform infrared spectroscopy and scanning electron microscopy techniques were performed to evaluate the physico-chemical parameters of prepared activated carbon material. In three-electrode electrochemical tests, the activated carbon WABAC3 provides the specific capacitance of 345 F g–1 at a current density of 1 A g–1 in 1 M Na2SO4 electrolyte with remarkable rate capability. It provides the cyclic stability of 91% of initial capacitance after 5000 continuous GCD cycles at a current density of 5 A g–1.
