Abstract

The progress in development of novel electrode materials is critical for invention of energy storage devices as increased energy consumption necessitates extremely effective energy conversion. The biomass material (waste) obtained from Brassica oleracea (Leaf) was successfully transformed into functional carbon for use as electrode materials in electrochemical applications. The samples BOL-800 and BOL-900 were characterized using FT-IR spectroscopy and elemental analysis, which indicated the presence of functional carbon. The XRD analysis confirmed the amorphous nature of the synthesized samples, whereas SEM images clearly confirmed the formation of micro-size pores. Thermogravimetric analysis of BOL-800 indicated the progression of gasification reaction. Specific capacitance values for samples BOL-800 and 900 were calculated using cyclic voltammetry and galvanostatic charge discharge at current density of 0.5 A/g. Among the tested electrodes, BOL-900 electrode was found to exhibit superior specific conductance.
