A promising thin film electrode material, ferric oxide (Fe2O3), was synthesized using the successive ionic layer adsorption and reaction (SILAR) technique for application in supercapacitors. Characterization of the Fe2O3 thin films was carried out using various analytical tools, including X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and energy dispersive X-ray analysis (EDAX). The electrochemical performance of the thin films was assessed through cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) measurements, and electrochemical impedance spectroscopy (EIS). The highest specific capacitance (Cs) recorded was 596 F/g at a scan rate of 5 mV/s in a 1 M KOH electrolyte. Additionally, the maximum energy density and power density obtained were 25.4 Wh/kg and 0.5 W/kg, respectively, at a current density of 1 mA/cm² in 1 M KOH. The internal resistance of the Fe2O3 thin film was found to be approximately 1.1 Ω. These results demonstrate that Fe2O3 is found suitable as a high-performance thin film electrode material for supercapacitors
