Critical review on the derivative of graphene with binary metal oxide-based nanocomposites for high-performance supercapacitor electrodes

Abstract

Supercapacitors, owing to their high power density and rapid charge-discharge capabilities, have gained significant attention as energy storage devices in various applications. In the context of electrochemical supercapacitors, this article provides a comprehensive review of the production and electrochemical performance of binary metal oxide (BMO) and reduced graphene oxide (rGO) composite materials. The synthesis processes and synergistic benefits of BMO-rGO composites, with an emphasis on how they perform better than separate parts in terms of specific capacitance and cycle stability, are discussed. The potential of BMO-rGO composites as high-performance electrode materials for supercapacitors is highlighted in this research. In the context of electrochemical supercapacitors, this work provides a comprehensive review of the production and electrochemical performance of binary transition metal oxide (TMO) and rGO composite materials. Composite materials with enhanced electrochemical characteristics that are appropriate for supercapacitor applications are the primary novelty, which is the synergistic combination of rGO with a variety of TMOs. Compared to individual TMOs or other carbonaceous materials, these composites demonstrate enhanced specific capacitance, energy density, power density, cyclic stability, and rate capability. The synthesis processes and synergistic benefits of BMO-rGO composites are discussed, with an emphasis on their superior performance in specific capacitance and cycle stability compared to individual components. This research highlights the potential of BMO-rGO composites as high-performance electrode materials for supercapacitors, showcasing their enhanced specific capacitance, improved charge storage capacity, increased power density, excellent cycling stability, and overall durability even after numerous charge-discharge cycles.
