Abstract

The performance of palm kernel shells as a supercapasitor electrode material has been studied. The supercapasitor was assembled by plate/sandwich methods. Both electrodes were separated by using a PVA (Polyvinil Alcohol) as a separator. Potassium hydroxide, KOH 10 M was used as activator in order to increase the capacitancy value. Prepared activated carbon as electrode material was characterized by XRD, FTIR, SEM-EDX and SAA methods. The activated carbon has 15 times more larger surface area is 27.2253 m2/g than carbon without activated which is 1.829 m2/g. Supercapasitor was fabricated by variation of particle size, plat area, electrolyte concentration and charging time to obtain the maximum capacitancy value that is 48.2516 µF with 3x11 cm2 plat area, charging time is 35 min, and H3PO4 electrolyte concentration as 0.3 N. Keywords: EDLCs, electrode, supercapasitor, method of plate/sandwich, PVA, separator
