Sb2S3基负极材料的制备及储能性能研究进展

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

  • 摘要: 由于在低电位范围内的合金化/脱合金化反应机制,硫化锑(Sb2S3)材料的理论放电比容量高达946 mA·h·g−1,是一种有发展前景的锂/钠/钾离子电池负极材料。然而,在电化学反应过程中Sb2S3材料的聚集性和较差的导电性限制了离子/电子转移,导致了较差的电化学性能,严重阻碍了其实际应用。有必要对Sb2S3基负极材料的结构设计和储锂/钠/钾机制及近几年来的一些重要工作进行总结。本文综述了近年来Sb2S3基化合物材料的研究进展,主要包括合理的结构设计和/或与碳基材料结合等策略及所涉及的电化学反应机制,并提出了进一步改善Sb2S3化合物负极材料的展望。

     

    Abstract: 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.
