ReS2-Based electrode materials for alkali-metal ion batteries

Alkali-metal (Li, Na, K) ion batteries have practically or potentially been widely used as power sources for portable electronic devices and electric vehicles. However, the lack of fast and high-capacity anodes is restricting their development. As a new member of two-dimensional transition metal dichalcogenides, rhenium disulfide (ReS2), with a large interlayer space and weak van der Waals interaction between layers, can enable a large number of intercalation ions to diffuse easily between the layers. In this review, we summarize the recent progress of ReS2 as an electrode for alkali-metal ion batteries, mainly focusing on the synthesis method, structures, the reaction mechanism, and the corresponding electrochemical performance. In addition, the perspective and challenges of ReS2 electrodes are also discussed. This review will provide comprehensive knowledge of ReS2 electrodes and guidelines for exploring more applications in batteries.
