Abstract

Most applications and devices in today's smart world rely on electricity to function. In this circumstance, energy storage and energy conservation are critical practices for delivering excellent service. In terms of energy efficiency, rotational stability, and charging and discharging time, supercapacitors exceed batteries. It can withstand a lot more power than standard capacitorsand batteries. In asymmetric designs, this paper looked at how to achieve the high voltage window and high energy storage capacity. Here, porous graphene is deposited on carbon cloth to form a cathode electrode on a supercapacitor, and the carbon cloth (CC) with carbon nanotube (CNT) is polymerized with polyaniline to act as an anode, and the electrochemical performance isinvestigated using PVA/ potassium hydroxide as an electrolyte. At a scan rate of 20 mV/s and a current density of 0.8 A/g, the suggested ASC obtained a specific capacitance of 220F/g. The proposed ASC has a 2 V as working voltage window that may be extended at a rate of 20 mV/s. This ASC's key benefit is that it can keep 98 percent of its energy after 5000 cycles. As a result , theproposed polymer-based anode and porous graphene oxide- based cathode is the optimum choice for constructing Asymmetric supercapacitors.
