Recently, biomass waste has become the focus of several researchers due
to promising potential when processed into porous activated carbon. Abundant
availability, uncomplicated processing, and more economical are the reasons for
choosing biomass as the basic material for making carbon electrodes for electrical
energy storage supercapacitors. In this study, torch ginger leaves waste biomass
was converted into activated carbon through ZnCl2 chemical activation and
heating at high temperatures. This research focuses on the effect of different
concentrations ZnCl2(0,1, 0,3, 0,5 and 0,7) M to obtain good electrochemical
properties. The monolith sample was optimized through a single-stage integrated
high-temperature pyrolysis process. The carbonization process of N2 gas from a
temperature of 30-600°C followed by physical activation of CO2 gas up to a
temperature of 800°C. The density of the carbon electrode decreases after the
pyrolysis process and X-Ray Diffraction (XRD) analysis showed that the samples
are predominantly amorphous with carbon content up to 90%. Cyclic voltammetry
and galvanostatic charge-discharge analyzes were performed with an aqueous
electrolyte of 1M H2SO4 at a potential in low 0-1 V and scan rate of 1 mV/s.
Furthermore, the electrochemical behavior of the high CV method was found to
be 217.42 F/g with fiber pore structure at the optimum concentration of ZnCl2 0.3
M. Moreover, an energy density of 30.19 Wh/kg and a optimum power density is
108.79 W/kg in the EE-0.3. Meanwhile, for the GCD method, the capacitance
value is much larger, namely 285.89 F/g. These results support the optimization of
0.3M ZnCl2 impregnated torch ginger leaves as a basic material for activated
carbon electrodes to increase the supercapacitor capacitance.
Keywords :Porous activated carbon, supercapacitors, torch ginger leaves, carbon
electrode, specific capacitance.
