ABSTRACT

A vital aspect of the modern-day energy supply chain is energy storage. Various metal ion rechargeable batteries can serve the purpose of energy storage. This can expand the efficiency of energy systems, boost the stability of the grid, conserve fossil fuel reserves, and enhance the penetration of green energy resources. Many efficient materials have been applied as electrode material in rechargeable batteries. Among them, transition metal dichalcogenides (TMDs) have gained the attention of researchers due to their high stability, low cost, and tunable activity. Among these TMDs, 2D vanadium dichalcogenides (VX2, where X = S, Se, Te) emerged as a promising material to be used in rechargeable batteries because vanadium provides a wide range of oxidation states. Different oxidation states result in a broad range of redox reactions that are suitable for energy storage systems. Also, vanadium dichalcogenides are cheap and earth abundant. In this chapter, we give an overview of the computational study and experimental fabrication of various 2D vanadium dichalcogenides and their composites. Potential applications of 2D vanadium dichalcogenides and composites of vanadium dichalcogenides in innovative energy storage systems like rechargeable batteries are also discussed.
