Carbon electrodes derived from palm leaf midrib biomass have the potential to be
used as supercapacitor carbon electrodes. Supercapacitor electrodes from palm
leaf midrib biomass were made through pre-carbonization process, chemical
activation using a potassium hydroxide activator with a concentration of 1 M, then
the carbonization process with variations in carbonization temperature of 650˚ C,
700˚ C and 750˚ C by flowing N2 gas and physical activation at 900˚ C by flowing
CO2 gas. The decreased in percentage of carbon mass after pre-carbonization
process was 28.82%. Thermogravimetric analysis showed that the thermal
resistance temperature of carbon powder from palm leaf midrib was 305˚ C. The
results of carbon electrode density showed that the PN650 sample carbonized at
650˚ C showed the lowest density of 0.3206 g / cm3. The microstructure analysis
shows that the carbon electrode was semi-crystalline that is characterized by the
presence of the diffraction peaks (002) and (100) at 2θ around 24 and 43. The
specific capacitance value of the supercapacitor cells measured using the cyclic
voltametry method for each sample was 223, 55 F / g, 96.87 F / g and 84.97 F / g.
Moreover, the largest capacitance value was found in the PN650 sample. The
results of this study indicated that the temperature of 650˚ C was the best
carbonization temperature in the preparation of supercapacitor cell electrodes
from palm leaf midrib.
