Summary

Transition metal di-chalcogenides (TMDCs) have the common formula MX 2 , where M represents the transition metal atom (Ni, Mo, Co, Mn, W, etc.), and X represents the chalcogenide atoms (S, Se, Te, etc.). These MX 2 types of TMDCs have received great interest as electrode materials for energy storage applications in rechargeable batteries because of their atomically layered structure, high surface area, and enhanced electrochemical characteristics. The aforementioned remarkable properties of these materials have made it possible for researchers to discover new materials in all fields over the past two decades. The weak van der Waals forces of attraction between the two layers are mainly responsible for their covalently bound nature. Various synthesizing methods, rechargeable batteries such as Li, Na, K, Mg, Zn, Al, and Li-S ions energy storage applications using various 2D-TMDCs were discussed in this chapter.
