Abstract: In this work, we present the effect of oxidation and optimum microwave irradiation time interval for the surface modification of agro-waste derived carbon and explore its application as high performing electrode material for supercapacitor application. The electrochemical performance of as-synthesized carbon was tested by using cyclic voltammetry (CV), galvanostatic charge- discharge (GCD), and the electrochemical impedance spectroscopy (EIS) with 1M H2SO4 as aqueous electrolyte in three electrode system. Highest specific capacitance obtained to be 215.7 Fg-1 at current density 0.5 Ag-1 for oxidized carbon material treated under microwave irradiation for 10s (FC-10) which is 61% higher as compare to untreated carbon derived from drump sticks (BC), with the capacitance retention of 94% at current density 5 Ag-1 over 2000 continuous charge discharge cycles. The highest energy and power density obtained to be 7.49 Whkg-1 and 62.5 Wkg-1 at current density 0.5 Ag-1 retained to be 5.78 Whkg-1 and 1250 Wkg-1 respectively, at current density 10 Ag-1 for FC-10. The modification of agro-waste derived carbon via oxidation followed by optimum irradiation approach demonstrates effective way to improve electrochemical properties for high performance supercapacitor application.
