DERIVING GRAPHENE NANOSHEETS FROM BIOMASS FOR HIGH POWER SUPERCAPACITORS

Abstract

Due to its environmental friendliness, quantity, and porous makeup, carbon derived from biomass has garnered much interest as an active component for supercapacitor electrodes. Our project employs self-template chemical and physical Simultaneous Activation and Graphitization methods to generate activated carbon from coconut shells. We then synthesize porous graphene-like Nanosheets (GPNs), which are used as an active component in the electrodes of environmentally friendly supercapacitors. The GPNs produced using this method exhibit a hierarchical porous graphitic phase, a high surface area, and a large pore volume, according to studies using Energy Dispersive Spectroscopy (EDS), Raman spectroscopy, conductivity, and scanning electron microscopy (SEM). The hierarchical porous morphology of the precursor material is correlated with the energy storage capabilities of activated carbon electrodes. The Electrochemical measurements and cyclability will be performed using Cyclic Voltammetry and galvanostatic Charge Discharge.
