High-performance cerium oxide thin film electrodes prepared by layered deposition technique for enhanced supercapacitor performance

Year: 2025

Type: article

Abstract: ABSTRACT This study focused on the synthesis of cerium oxide (CeO 2 ) electrodes using the Successive Ionic Layer Adsorption and Reaction (SILAR) method to enhance supercapacitor performance. The fabricated thin films exhibited a face-centered cubic structure of cerium oxide with a distinctive cauliflower-like nanostructure. This unique morphology increased the surface area, facilitated efficient ion diffusion, and significantly improved the electrochemical performance. The CeO 2 electrodes achieved a high specific capacitance of 659 F/g at a scan rate of 5 mV/s, as measured by cyclic voltammetry. The electrodes delivered a maximum energy density of 64 Wh/kg and a power density of 3499 W/kg. These results demonstrated that CeO 2 thin films are promising candidates for advanced supercapacitors and hold great potential for future energy storage applications.
