The growing demand for sustainable and high-performance energy storage systems has accelerated research on eco-friendly electrode materials for supercapacitors. The storage performance of the device depends upon the properties of the electrode materials i.e. morphology, surface area, shape, size, conductivity and stability during cycling. This study focuses on the development of a chitosan-coated Fe₃O₄/reduced graphene oxide (rGO) composite as an eco-friendly electrode material for supercapacitors. Chitosan acts as a biopolymer binder and stabilizer, improving the dispersion and conductivity of Fe₃O₄ on rGO. The composite was synthesized via a simple solution-based method and characterized using FTIR, XRD, SEM, and Raman spectroscopy. Electrochemical tests (CV, GCD, EIS) confirmed enhanced capacitance, good cycle stability, and low resistance. The results highlight the potential of chitosan–Fe₃O₄–rGO hybrids for sustainable energy storage applications.
