Most cocoa shells contain carbon which can be used as an electrode. Through nano carbon, cocoa skin has the potential to be an electrode material in supercapacitors. Nano carbon is a form of carbon that has a large surface area and pore volume. Material characteristics through FT-IR test showed that the intensity of wave absorption in the graphite group (C-C) decreased which indicates an increase in carbon. The XRD results show that carbon nano has a peak of purity close to graphite at 2θ: 24.75º on the lattice values (002). So that the nano carbon based supercapacitor electrode has an electrode resistance value of 0.0307 S/m with a specific capacitance value of 5.19 F/g.
