Abstract
Sodium-ion battery (SIB), one of most promising battery technologies, offers an alternative low-cost solution for scalable energy storage. Developing advanced electrode materials with superior electrochemical performance is of great significance for SIBs. Transition metal sulfides that emerge as promising anode materials have advantageous features particularly for electrochemical redox reaction, including high theoretical capacity, good cycling stability, easily-controlled structure and modifiable chemical composition. In this review, recent progress of transition metal sulfides based materials for SIBs is summarized by discussing the materials properties, advanced design strategies, electrochemical reaction mechanism and their applications in sodium-ion full batteries. Moreover, we propose several promising strategies to overcome the challenges of transition metal sulfides for SIBs, paving the way to explore and construct advanced electrode materials for SIBs and other energy storage devices.
