Abstract
The activated carbon electrode of a supercapacitor cell based on palm fiber has been
successfully fabricated. This research aims to determine the effect of carbonization
temperature on the density and specific capacitance values of activated carbon
supercapacitor cells made from palm fiber. The process of preparation of supercapacitor
electrode cells started with pre-carbonization using an electric oven at temperature of
100-250 oC. The chemical activation was performed using a 0.3M ZnCl2 activator. The
carbonization process was carried out using N2 gas environment with temperature
variations of 500 oC, 550 oC and 600 oC. The physical activation was done using CO2
gas at a temperature of 700 oC. The density of the carbon electrode decreases by 7.92%
at 500 oC, 9.43% at 550 oC and 10.09% at 600 oC after carbonization-physical activation
process. The sample with a temperature of 600 oC results the highest specific capacitance
as high as 101 F/g.
