摘要

The production of activated carbon electrodes from a banana stem for supercapacitor cell applicationshas been successfully performed. The increase in pore properties was conducted using a KOHchemical activation agent at low concentrations of 0.0, 0.3, 0.5 and 0.7 M, whereas physical activationwas performed using CO2 gas at a temperature of 850 ?C for 2 h. The activated carbon electrode wasfabricated without the addition of adhesive materials. The density, degree of crystallinity, surfacemorphology, elemental content and surface area of the electrodes were analyzed. The study ofelectrochemical properties focused on the analysis of the specific capacitance of the supercapacitor cellusing cyclic voltammetry. The physical properties of the activated carbon electrodes were correlated togenerate the optimum conditions for the specific capacitance of the supercapacitor cells. The optimumspecific capacitance obtained at a concentration of 0.5 M KOH reached 170 F/g with a specific surfacearea of 835.939 m2/g.
