Lithium metal is regarded as one of the most ideal anode materials for next-generation batteries, due to its high theoretical capacity of 3860 mAh g⁻¹ and low redox potential (−3.04 V vs standard hydrogen electrode). However, practical applications of lithium anodes are impeded by the uncontrollable growth of lithium dendrite and continuous reactions between lithium and electrolyte during cycling processes. According to reports for decades, artificial solid electrolyte interface (SEI), electrolyte additives, and construction of three-dimensional (3D) structures are demonstrated essential strategies. Among numerous approaches, metals that can alloy with lithium have been employed to homogenize lithium deposition and accelerate Li ion transportation, which attract more and more attention. This review aims to summarize the lithium alloying applied in lithium anodes including the fabricating approaches of alloy-containing lithium anodes, and the action mechanism and challenges of fabricated lithium anodes. Based on summarizing the literature, shortcomings and challenges as well as the prospects are also analyzed, to impel further research of lithium anodes and lithium-based batteries.

锂金属被认为是下一代电池最理想的负极材料之一，因为它具有 3860 mAh g ^{-1的高理论容量}和低氧化还原电位（-3.04 V vs 标准氢电极）。然而，锂负极的实际应用受到锂枝晶不可控生长以及锂与电解质在循环过程中的连续反应的阻碍。根据几十年来的报道，人工固体电解质界面 (SEI)、电解质添加剂和三维 (3D) 结构的构建被证明是必不可少的策略。在众多方法中，可以与锂形成合金的金属已被用于均匀化锂沉积并加速锂离子运输，引起越来越多的关注。本综述旨在总结应用于锂负极的锂合金化，包括含合金锂负极的制造方法，以及制造锂负极的作用机制和挑战。在总结文献的基础上，分析了不足和挑战以及前景，以推动锂负极和锂基电池的进一步研究。
