Utilization of potato peel waste as a basic material in the fabrication of
supercapacitor electrodes has been successfully carried out.in this study potato
peel-based carbon electrodes prepared through a single-stage integrated pyrolysis
with carbonization from room temperature to 600°C in a N2 gas atmosphere
followed by physical activation at temperature of 850°C in a CO2 gas
environment. The impregnation of ZnCl2 at different concentrations was optimized
as an independent variable precursor to produce porous activated carbon for
supercapacitor energy storage devices. The difference in concentration of 0.1M,
0.3M and 0.5M ZnCl2 can increase the porosity, structure of amorphous carbon
and high electrochemical performance resulting. Based on density measurements,
the largest shrinkage was shown by sample ST-0.3. The results of XRD
characterization showed that there were 2 peaks with an angle of 2 at 25.529°-
25,754° and 43.932°-44.634° which indicated that the carbon electrode had an
amorphous structure. The electrochemical properties were characterized by using
cyclic voltammetry and galvanostatic discharge methods in an aqueous electrolyte
of 1 M H2SO4 at a voltage of 0-1000 mV and a scanning rate of 1 mV/s.
Furthermore, the resulting specific capacitance increased from 82.82 F/g, 195.66
F/g and 147.03 F/g based on the concentration effect of the chemical activator
ZnCl2. While the specific capacitance obtained using the GCD method showed
higher numbers, namely 145.13 F/g, 223.25 F/g and 174.08 F/g. The energy
density is 27.18 Wh/kg and the power density is 97.93 W/kg from the CV method.
The simple approach of activated carbon from potato peel waste is expected to
produce an economical and simple porous carbon electrode for high performance
energy storage applications.
Keywords : potato peel, supercapacitor, carbonization, physical activation,
