Abstract

A paper supercapacitor employing carbon electrodes derived from coffee ground was successfully fabricated. The device was characterized using Cyclic Voltammetry, charge-discharge potentiometry, and impedance spectroscopy. The behaviors of the responses observed are consistent with previous findings, confirming supercapacitive effect. The specific capacitance was computed to be around 3-5 F/g.
