Enhanced supercapacitor performance through CdFe2O4-rGO nanocomposites: synergistic effects for advanced energy storage
Source abstract
Abstract
The need for reliable and effective energy storage systems has grown because of the world’s growing energy needs and the quest for sustainable technology. Researchers are interested in supercapacitors because they can charge and discharge quickly, have a high power density, and last a long time. To meet future energy storage requirements, the fabrication of advanced electrode materials is essential.This study focuses on developing CdFe₂O₄-rGO nanocomposites, leveraging the synergistic combination of cadmium ferrite (CdFe₂O₄), a redox-active spinel oxide, and reduced graphene oxide (rGO), a highly conductive material, to enhance supercapacitor performance. The integration of these materials improves electrochemical properties by combining pseudocapacitive and double-layer capacitance mechanisms, with CdFe₂O₄ providing excellent redox activity and rGO enhancing conductivity and surface area, thus elevatingactive sites for ion adsorption and redox reactions.Morphological studies reveal that CdFe 2 O 4 bundles of clustered platelets are uniformly anchored on rGO sheets, creating a well interconnected structure that facilitates efficient ion diffusion and electron transfer.Comprehensive structural (XRD and FTIR) and electrochemical analyses confirm the superior charge storage capacity and long-term cycling stability of the rGO-CdFe₂O₄ composite, which exhibits a specific capacitance (C sp ) of 340.08 Ag −1 . Future research could explore optimizing the synthesis process and investigating the composite’s performance in hybrid energy storage systems to further enhance its practical viability.
