ABSTRACT = {Several studies have reported a growing interest in nanomaterials beyond conventional graphite, driven by the rapid global demand for sustainable, high-performance energy storage. Among these materials, two-dimensional (2D) transition metal chalcogenides (TMCs), molybdenum- and tin-based systems such as molybdenum disulfide (MoS<sub>2</sub>) and tin (IV) disulfide (SnS<sub>2</sub>) in particular, have emerged as promising candidates for next-generation electrochemical energy storage devices (EESDs). This is owing to their unique X-M-X sandwich architectures, tunable electronic properties, and versatile intercalation chemistry. Despite several studies on 2D TMCs and their applications in EESDs, a gap still exists, as there is no comprehensive review that integrates advanced synthesis routes and multi-scale characterization with phase engineering (particularly the 2H-to-1T transition) and defect engineering strategies, not just for MoS<sub>2</sub> and SnS<sub>2</sub> but also for other 2D TMCs (e.g., WS<sub>2</sub> and ReS<sub>2</sub>), while taking advantage of Density Functional Theory (DFT) as a predictive tool for electronic structure, ion adsorption energies, and diffusion barriers. Additionally, the review examines the sustainable utilization of local mineral precursors, such as Nigerian lithium-bearing ores, for the production of 2D TMCs. Overall, this review provides a comprehensive framework for the rational design and optimization of 2D chalcogenide-based nanomaterials for high-capacity lithium-, sodium-, and potassium-ion storage devices.},
