ABSTRACT
Transition metal chalcogenides (TMCs) are wonder materials that can provide path-breaking results in various fields of application. The level of ongoing research on these materials is expected to yield several promising aspects of these excellent performers, whether it is catalysis or charge trapping through the faradic process, could pave the way for a myriad of possibilities in realizing the green energy revolution. The presence of edge plane and basal plane and resulting electrochemistry makes these TMCs highly versatile, and thus can be taken for virtually any kind of applications. They are highly electro-active, and are abundantly available in the earth’s crust, which can address the issues that are currently faced by the Li-ion industries (owing to the limited lithium reserve). In the context of energy storage, especially supercapacitors, these materials provide a wide range of choices. They can be combined with EDLC materials to form an asymmetric arrangement of electrodes that could boost the working potential window and strike a balance between energy and power density. In this chapter, we have discussed on different synthetic methodologies for the preparation of TMCs. Further, the application of these materials towards electrochemical energy storage has been discussed with an updated literature survey. We 2presume that this chapter will be helpful to boost the knowledge of the energy researchers on these energy storage systems.
