Abstract
In order to increase the performance of rice husk-derived activated carbon (RHAC) in energy storage devices such as supercapacitors and aluminum-air (Al-air) batteries, this study explores the improvement of RHAC using atmospheric air plasma treatment. The surface features and electrochemical properties of RHAC were altered through plasma treatment. Several characterization methods, including electrochemical analysis, FE-SEM, XRD, FTIR, and Raman spectroscopy, revealed significant increases in surface area, porosity, and functional group formation, confirming the advantages of plasma treatment. Following plasma treatment, the RHAC exhibited considerable enhancement in specific capacitance, reaching 1298 F g⁻¹, and surface hydrophilicity, with the contact angle decreasing from 113° to 67°. By combining sustainable materials with innovative modification techniques, this research contributes to the development of eco-friendly and efficient energy storage solutions.
