Potassium ion batteries (PIBs), characterized by the superiorities of low cost, moderate operating voltage and fast kinetics in electrolytes, are expected to narrow the gap between the energy storage systems based on abundant elements and lithium ion batteries (LIBs). However, the large size of K+ is not conducive to electrochemically reversible storage, limiting the practical application of PIBs. It is imperative to develop anode materials with salient performance for K+ storage. Bismuth-based materials stand out as promising candidate attributed to their low cost, high theoretical capacity, suitable reaction potential and large interlayer spacing. In this contribution, the recent research advances in Bi-based anode materials for PIBs, including metallic Bi-based materials and Bi-based compounds, are overviewed, focusing mainly on the K+ storage mechanisms and the relationship between the structure and performance of electrode materials. Particularly, the critical role of electrolyte optimization for Bi-based anode materials is emphasized. Finally, the prevailing challenges and prospects for the further development of Bi-based anodes are outlined. This review sets out to present a comprehensive knowledge of Bi-based anode materials for PIBs and stimulates further research towards practical applications.

钾离子电池铋基阳极的进展
钾离子电池（PIB）具有成本低、工作电压适中、电解质动力学快等优点，有望缩小基于丰富元素的储能系统与锂离子电池（LIB）之间的差距。然而，K +的大尺寸不利于电化学可逆存储，限制了PIB的实际应用。开发具有优异储K +性能的负极材料势在必行。铋基材料因其低成本、高理论容量、合适的反应电位和大的层间距而成为有前途的候选材料。本文综述了PIB用铋基负极材料（包括金属铋基材料和铋基化合物）的最新研究进展，主要关注K +存储机制以及电极结构与性能之间的关系材料。特别强调了电解质优化对于铋基负极材料的关键作用。最后，概述了铋基负极进一步发展面临的挑战和前景。本综述旨在介绍用于 PIB 的铋基负极材料的全面知识，并促进实际应用的进一步研究。
