Abstract:
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. In this research,
the carbon electrode derives from waste of Christmas palm with carbonization
temperature variation. Optimization efforts were made for the carbonization process
in the fabrication of electrodes in order to obtain a high specific capacitance. Initial
preparation was started from the pre carbonization process at temperature of 200℃.
The activated carbon powder was converted into a monolith using a hydraulic press
and then followed by carbonization process with temperature 600℃ under an N2 gas
environment and activated by CO2 gas at 800℃. Specific capacitance was determined
by cyclic voltammetry method and it is found to be as high as 108,99 F/g, 92,43 F/g,
78,16 F/g and 67,62 F/g for scanrate of 1 mV/s, 2 mV/s 5 mV/s dan 10 mV/s
respectively.
