Synthesis and Characteristics of Bamboo-based Activated Carbon as Electrode Materials

The environmental impact of conventional electrode materials poses a significant challenge to the advancement of sustainable energy storage technologies. In response to the growing demand for eco-friendly alternatives, biomass-derived materials have gained attention as promising candidates. This study explores the use of bamboo as a fast-growing, renewable resource to synthesize activated carbon for supercapacitor electrodes. Through potassium hydroxide (KOH) activation, a porous carbon structure was developed and characterized using scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), X-Ray Diffraction (XRD) and cyclic voltammetry (CV). The bamboo-derived activated carbon demonstrated excellent electrochemical performance, with optimal results achieved at 7% KOH concentration and a scan rate of 75 mV/s, indicating strong cyclic stability. These findings highlight that the potential of bamboo-derived activated carbon offers as sustainable and high-performance electrode material for next-generation energy storage systems.
