ABSTRACT
Biomass-based porous Carbon electrodes have been widely used as a basic material for producing supercapacitor cell electrodes, because its application can be applied in the long term, sustainable, renewable, easy to find and has economic value. This research used biomass Guinea grass (RG) with ZnCl2 molarity variations of 0.1 M, 0.3 M, and 0.5 M as carbon electrodes for supercapacitor cells. The process of synthesizing supercapacitor cell electrodes is through several stages a pre-Carbonization at 200°C, chemical activation, Carbonization with N2 gas at temperature of 800°C and physical activation with CO2 gas at temperature 900°C. The highest density shrinkage value is owned by the RG-05 sample is 61.21%. Analysis Fourier Transform Infra Red showed that the active Carbon of Guinea grass contained the functional groups O-H, C=O, C-O, C≡C and C-H. X-Ray Diffraction analysis shows that there are two peaks at an angle of 2θ angles of 22o and 44o at scattering fields (002) and (100) which identify amorphous characteristics. Analysis Scanning Electron Microscopy showed the formation of porous Carbon electrodes with nanosheet and nanofiber structures. Analysis Energy Dispersive X-Ray showed that the RG-05 sample produced the largest percentage of Carbon at 88.01% of the three samples. Electrochemical analysis of supercapacitor cells using the Cyclic Voltammetry and Galvanostatic Charge-Discharge methods with 1 M H2SO4 electrolyte, shows the highest specific capacitance values were owned by the RG-05 sample of 487 Fg-1 and 495 Fg-1. In conclusion the biomass derived from Guinea grass (RG), which is underutilized and wasted, has the potential to use as a porous carbon electrode for high-performance supercapacitor cell applications.
Keywords: Guinea grass, carbon electrode, ZnCl2, supercapacitor.
