Type: article

Abstract: Composite supercapacitive electrode materials offer significant advantages over single-component electrodes by leveraging the synergistic effects of their constituents. In this study, we synthesised a layered heterostructure of ZnFe₂O₄ and reduced graphene oxide (RGO) on nickel foam using a one-step hydrothermal method. The integration of ZnFe₂O₄, known for its high theoretical capacitance, with RGO, which enhances electrical conductivity and structural stability, addresses key limitations of individual materials and results in superior electrochemical performance. The synthesized electrode exhibited an outstanding specific capacitance of 1029 F/g, demonstrating excellent charge storage capability. To evaluate practical applicability, the ZnFe₂O₄/RGO composite electrode was employed in the fabrication of asymmetric supercapacitor devices. The results indicate enhanced energy storage performance, highlighting the potential of ZnFe₂O₄/RGO as a promising material for high-performance supercapacitors. Further investigations into its long-term cycling stability and energy density could pave the way for its integration into next-generation energy storage technologies.
