Abstract
Supercapacitor electrodes made from Palm fiber were prepared by carbonization and
activation process which consist of several steps such as pre-carbonization, milling,sieving,
chemical activation, pelletization, and carbonization-physical activation. Chemical activation
was performed using potassium hydroxide (KOH). KOH concentration on the activation
process of palm fiber charcoal varied as much as 0,2 M, 0,3 M and 0,4 M. The activated carbon
was made through the pre-carbonization using an electric oven at temperature of 100-250 0C.
The carbonization process was conducted in N2 gas environment at 600 0C and followed by
physical activation at a temperatur of 700 0 C using CO2 gas for 1 h. The physical property of
electrodes analyzed is its density. The electrochemical properties of the electrodes were
explored using a two-electrode system while the capacitive properties of the electrodes was
determined using cyclic voltammetry. The electrochemical properties of the electrodes
showed excellent capacitive properties of a supercapacitor cell, with very high specific
capacitance of 162,99 F/g.
