Abstract
The pursuit of advanced energy storage systems beyond lithium-ion batteries has intensified, driving the exploration of alternative electrode materials. Molybdenum disulfide (MoS 2 ) and its nanocomposites have emerged as promising active material candidates due to their unique structural characteristics and electrochemical properties . In this review, we provide a comprehensive overview of synthesis and design strategies of MoS 2 -based electrode materials tailored to address the challenges posed on rechargeable batteries by large Na + and K + ions, as well as the multivalent nature of Zn 2 + , Mg 2 + , and Al 3＋ ions. We review various structural design/modification strategies, such as interlayer engineering, defect engineering, crystal phase (1T/2H) engineering, heteroatom doping , hybridization, and morphology design. Through an examination of previous theoretical and experimental research, we summarize their impacts on enhancing the electrochemical performance of MoS 2 -based active materials, aiming to improve their capacity, kinetics, reversibility, and stability in post-lithium-ion storage. By compiling numerous research findings, this review offers insights into the rational design principles that guide the development of high-performance layered active materials for next-generation energy storage devices. With MoS 2 as a prototype transition metal dichalcogenide (TMD), these principles are applicable to other layered battery materials, contributing to the advancement of sustainable and efficient electrochemical energy storage technologies.
