ReS2-Based electrode materials for alkali-metal ion batteries

Abstract

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.
