Abstract

Chalcogenides have attracted great attention as functional materials in optics, electronics, and energy-related applications due to their typical semiconductor properties. Among those chalcogenides, Sb₂S₃ holds great promise in energy storage field, especially as an anode material for alkali metal (Li, Na, and K) batteries. In this work, a one-dimensional coaxial Sb₂S₃@PPy is investigated as a versatile and robust anode in three kinds of alkali metal batteries for the first time, and the energy storage mechanism of these batteries is systematically discussed. As an anode material for sodium ion batteries (SIBs) and potassium ion batteries (KIBs), Sb₂S₃@PPy exhibits high reversible capacity and impressive cycle lifespan. Sb₂S₃@PPy anode demonstrates an adsorption behavior that has a significant influence on its sodium storage behavior, providing a universal model for studying the application of chalcogenide compounds.

摘要

硫族化物因其典型的半导体特性，作为光学、电子和能源相关应用中的功能材料而备受关注。在这些硫族化物中，Sb₂S₃在储能领域具有巨大潜力，尤其是作为碱金属（锂、钠和钾）电池的负极材料。在这项工作中，首次研究了一维同轴结构的Sb₂S₃@PPy作为三种碱金属电池中通用且坚固的负极，并系统地讨论了这些电池的储能机制。作为钠离子电池（SIBs）和钾离子电池（KIBs）的负极材料，Sb₂S₃@PPy表现出高可逆容量和令人印象深刻的循环寿命。Sb₂S₃@PPy负极表现出一种对其储钠行为有重大影响的吸附行为，为研究硫族化物化合物的应用提供了一个通用模型。
