The generation of renewable energy is a promising solution to counter the rapid increase in energy consumption. Nevertheless, the availability of renewable resources (e.g., wind, solar, and tidal) is non-continuous and temporary in nature, posing new demands for the production of next-generation large-scale energy storage devices. Because of their low cost, highly abundant raw materials, high safety, and environmental friendliness, aqueous rechargeable multivalent metal-ion batteries (AMMIBs) have recently garnered immense attention. However, several challenges hamper the development of AMMIBs, including their narrow electrochemical stability, poor ion diffusion kinetics, and electrode instability. Transition metal dichalcogenides (TMDs) have been extensively investigated for applications in energy storage devices because of their distinct chemical and physical properties. The wide interlayer distance of layered TMDs is an appealing property for ion diffusion and intercalation. This review focuses on the most recent advances in TMDs as cathode materials for aqueous rechargeable batteries based on multivalent charge carriers (Zn, Mg, and Al). Through this review, the key aspects of TMD materials for high-performance AMMIBs are highlighted. Furthermore, additional suggestions and strategies for the development of improved TMDs are discussed to inspire new research directions.
可再生能源的产生是应对能源消耗快速增长的一个有前景的解决方案。然而，可再生资源（如风能、太阳能和潮汐能）的可用性本质上是不连续和暂时的，这对下一代大规模储能装置的生产提出了新的要求。由于其低成本、原材料高度丰富、高安全性和环境友好性，水系可充电多价金属离子电池（AMMIBs）最近受到了极大的关注。然而，几个挑战阻碍了AMMIBs的发展，包括其狭窄的电化学稳定性、较差的离子扩散动力学和电极不稳定性。过渡金属二硫属化物（TMDs）因其独特的化学和物理性质而被广泛研究用于储能装置。层状TMDs的宽层间距对于离子扩散和嵌入是一个吸引人的特性。本综述重点关注基于多价电荷载体（锌、镁和铝）的水系可充电电池中TMDs作为正极材料的最新进展。通过本综述，突出了用于高性能AMMIBs的TMD材料的关键方面。此外，还讨论了开发改进型TMDs的其他建议和策略，以激发新的研究方向。
