Abstract

The Effect of Activated Carbon of Palm Kernel Shell by NaOH as Supercapasitor Electrode Material Geby Dettania (1310411051) OllyNorita Tetra, M.Si*, Prof. Dr. Admin Alif* *Advisor Carbon from Palm Kernel Shell was activated by NaOH for used as supercapasitor electrode material. The supercapasitor was assembled by plate/sandwich methods. Both electrodes were separated by using a PVA (Polyvinil Alcohol) as a separator. Potassium hydroxide, NaOH 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 34 times more larger surface area is 43.792 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 38.108 µF with 3x11 cm2 plat area, charging time is 35 min, and H3PO4electrolyte concentration as 0.3 N. Keywords:electrode, supercapasitor, method of plate/sandwich, PVA, separator
