ABSTRACT
Research on activated carbon made using palm fiber biomass which is
applied as supercapacitor electrodes has been done. Supercapacitor is an energy
device that has high power and has a long life cycle. In the research, the activated
carbon was prepared through the pre-carbonization using an electric oven at
temperature of 100-250 0C and chemical activation processes using KOH
activator. The variations in KOH concentrations were 0,2 M, 0,3 M and 0,4 M.
The carbonization process was performed using N2 gas environment with
temperature of 600 0C and physical activation using CO2 gas at a 700 0C.
Diffraction analysis shows that the resulted pattern has an semy cristalline
structure which is characterized by the presence of ramps at 002 and 100 at angle
0f 2θ around 230 And 450. The Lc value increases with increasing concentration of
KOH. The carbon electrode with concentration 0,4 M has a highest of stack height
Lc of 8,96 Ǻ and lowest of stack diameter La of 9,80 Ǻ compared carbon
electrodes with concentration of 0,3 M and 0,2 M. This result is also supported by
a surface morphology analysis which shows that the carbon electrode with
concentration 0,4 M has more pores and evenly distributed compared to that of
carbon electrodes with concentration of 0,2 M and 0,3 M. The atomic content of
carbon is 92,82 %. Characterization of electrochemical property of supercapacitor
cell using cyclic voltammetry showed the highest specific capacitance 175,64 F/g
for electrode carbon with KOH concentration of 0,4 M, which is supported by the
results of microstructure analysis and the analysis of surface morphology.
Keywords : palm fiber, potassium hydroxide, activated carbon, physical
properties, supercapacitor electrodes.
