Synergistic effects in MXene: Transition metal chalcogenides to unlock supercapacitor potential

The foremost nations and scientific circles are focusing the spotlight mainly on energy because of the shifting global environment. The development and upgrade of energy storage systems featuring higher efficiency have drawn a great deal of concern. Therefore, significant advancements in energy storage might be made possible by a high-power density device called a supercapacitor (SCs). The use of 2D layered materials has sparked a lot of attention in the modern era since these materials have suitable electrochemical and physiochemical properties that make them ideal for high-performance energy storage devices. Amidst several 2D materials, MXenes have garnered significant interest due to their hydrophilic nature, metallic conductivity, rich active sites, and high surface area. In virtue of these upsides, compositing MXene with electrochemically favourable Ternary Metal Chalcogenides (TMCs) electrode material will significantly improve the composite performance by reducing the agglomeration of nanoparticles and inhibit restacking of MXene sheets through synergistic effects. This chapter mainly focuses on the MXene-TMCs composites for supercapacitor application and discusses the process involving them.
