Biomass-derived porous carbon is one of the most competitive electrode materials
for supercapasitor due to their renewability and sustainability. Electrode materials
derived from biomass for supercapacitors are considered as an effective solution
to the problems of the energy crisis and the environment deterioration.
Optimization efforts are made for the carbonization process in the manufacture
ofelectrodes in order to obtain a high specific capacitance. Biomass of empty
palm fruit bunches is selected as a base material for making carbon electrodes
throught a pre-carbonization process, chemical activation with KOH 0,5 M
activator, carbonization process with variations in temperature 6500C, 7000C,
7500C,and 8000C under an N2 gas environment, and activated by CO2 gas at
9000C. Reduce of carbon mass by 20,182 % and produce carbon powder.
Thermogravimetry show that thermal resistance temperature of 307 a carbon
powder. The density value of each carbon electrode for carbonization temperature
of 6500C, 7000C, 7500C and 8000C is 0,557 g.cm-3, 0,622 g.cm-3, and 0,702 g.cm-
3, respectively. Microstructure analysis shows that amorphous structure for the
activated carbon electrodes showed by the presence of the peaks of 2θ around 240
and 440. Specific capacitance was determined by cyclic voltammetry method and
its found to be as higs as 110,57 F/g, 180,02 F/g, 141,05 F/g and 121,63 F/g for
carbonization temperature of 6500C, 7000C, 7500C and 8000C, respectively. The
results showed that the temperature of 7000C is the best carbonization temperature
in production of carbon electrodes from TKBA. Therefore, as-prepared porous
carbons derived from empty palm fruit bunches with low cost, easy availability,
high regenaration ability and sustainability have a promising application as the
electrode materials for supercapasitors.
