摘要:

锂金属负极因具有极高的比容量和最低的电化学平衡电位,其应用一直受到人们的广泛关注。然而,锂枝晶在重复循环过程中引起的寿命短和安全性问题阻碍了锂金属电池的实用化。锂金属与电解质之间的复杂界面在调节锂沉积和提高电池循环稳定性方面起着非常重要的作用。通过对近期相关文献的探讨,综述了当前构建保护层作为人工SEI的有效预处理策略的关键进展,着重介绍了不同物质状态的处理策略及人工界面稳定锂金属负极的作用机制。最后展望未来预处理技术与锂金属负极的应用,包含开发先进策略、探索应用前景、解析影响机制等方面,提出了高能量密度锂金属电池当前的挑战、机遇和可能研究方向。

Abstract:

Lithium metal anodes (LMAs) have attracted substantial attention for their extremely high specific capacity and lowest electrochemical equilibrium potential. However, their short lifespan and safety issues owing to lithium dendrite formation during repeated cycling hinder the practical application of lithium metal batteries (LMBs). The complex lithium metal-electrolyte interface plays a crucial role in regulating lithium deposition and enhancing the cycling stability of the battery. This review summarizes key advancements in pre-treatment strategies for constructing protective artificial solid-electrolyte interphase layers, categorized by the physical states of the reagents (solid, liquid, and gas) and their mechanisms for stabilizing LMAs. Finally, this review outlines future directions for pre-treatment technologies, emphasizing advanced strategies, application prospects, and mechanistic insights, while addressing current challenges, opportunities, and potential research directions toward high-energy-density LMBs.

Key words: lithium metal anode, solid electrolyte interphase, lithium dendrites, pre-treatment strategies, artificial SEI
