Research progress on preparation and energy storage properties of Sb₂S₃-based anode materials

Due to the alloying/dealloying reaction mechanism in the low potential range, the theoretical discharge specific capacity of antimony sulfide (Sb₂S₃) material is as high as 946 mA·h·g⁻¹, which is a promising anode mater-ial for lithium/sodium/potassium ion batteries. However, the aggregation and poor conductivity of Sb₂S₃ materials limit ion/electron transfer, resulting in poor electrochemical performance and severely hindering its practical application. It is necessary to summarize the structural design and lithium/sodium/potassium storage mechanism of Sb₂S₃-based anode materials and some important work in recent years. This article reviews the research progress of Sb₂S₃ based compound materials in recent years, mainly including reasonable structure design and/or combining with carbon-based materials and the electrochemical reaction mechanism involved, and puts forward the prospect of further improving Sb₂S₃ compound anode materials.
