Currently, Lithium-ion batteries (LIBs) have been considered as the most widely used energy source for portable electronics devices owing to their superior capacity, high operational voltage, and long cycle life. Although they are well established for mobile electronics, further improvements of their performance are essential for employing them in electric and hybrid electric vehicle applications. In general the performance of a LIB mainly depends upon its electrode materials. For cathode, the transition metal oxides and phosphates are the well established materials while graphite and other carbon based compounds are commonly used as anode. The excellent electrical conductivity, high structural stability, layered structure and low coast make graphite as a pivotal choice for LIB anode. Nevertheless, the low theoretical specific capacity (372 mAh/g) of graphite anode is a major drawback. Although Silicon (Si) is considered an alternative option for graphite due to its high abundance and exceptional specific capacity, the drawbacks such as poor electronic conductivity and massive volume expansion are the critical drawbacks. By reducing the dimensionality of bulk Si, some improvement has been already reported. Even so, its commercialization still remains a challenging task. Thus, it is essential to find alternative materials that can offer high capacity, excellent electronic conductivity and durable cycle life. Graphene, the most celebrated 2D material, exhibits high capacity in LIBs as it can store Li-ions on its both sides and edges. Besides, the charge transport in the graphene electrode is exceptionally faster due to the Dirac cone's presence in its electronic structure, which allows the electrons to behave as massless fermions. As a result of the intriguing physicochemical properties, graphene and several graphene containing compounds have been successfully utilized as both anode and cathode materials in LIBs. Besides graphene, efforts have been made to fabricate LIBs from other 2D materials like silicene, hexagonal boron nitrides (h-BN), borophene, silicon carbides, transition-metal dichalcogenides (TMDs), and MXenes. Among these 2D materials the TMDs attracted battery researchers as many of them can be synthesized from their bulk phase by several methods such as exfoliation, chemical vapor deposition and super critical assisted methods. The TMDs have general formula MX 2 , where M is a transition metal (e.g. V, Mo, W, Ta, Nb and Re) and X is the chalcogenides (S, Se and Te). The 2D-molybdenum disulfide (MoS 2 ) is considered as the flagship material among various TMDs, and it is the most explicitly studied TMD for diverse fields including LIB applications. In recent times 2D-WS 2 has also attracted researchers due to its striking structural similarities with MoS 2 . For example, WS 2 also exist in three crystal structure namely 2H, 1T and 3R as similar to MoS 2 . For both TMDs, the 2H phase has been reported to be the most stable one, and which is semiconducting in nature.
