Abstract Scope |
The synthesis of transition metal dichalcogenide (TMD) alloys presents significant challenges along with high energy consumption due to their intricate structures, which consequently increases their commercial cost. As a result, most of the research efforts have prominently concentrated on TMDs only, such as MoS2 and WS2, with a limited number of studies addressing their alloys, specifically for energy storage applications. In this study, we have proposed a one-step process for bulk synthesis of cation-substituted TMD from commercially available precursors and also studied the structural and morphological properties. Further, the electrochemical properties of the synthesized TMD alloy were studied for Lithium, Sodium, and Potassium-ion batteries using various techniques, and post-cycling analysis. A voltage cut-off method has also been introduced to reduce irreversibility and structural distortion while improving performance stability and coulombic efficiency. This study establishes the foundation for further TMD alloy-based research into diverse alkali-metal-ion energy storage devices. |
