Abstract

Lithium (Li) metal is considered as the “Holy Grail” among various anodes due to its high theoretical specific capacity and low electrochemical potential. However, the Li anode undergoes uncontrollable dendrite growth and infinite volume expansion during cycling, seriously impeding the commercialization of high-energy-density Li metal batteries (LMBs). Considering the Li deposition is a dynamic electrochemical process, the external filed regulation has become a hotspot strategy to promote the cycling performance and safety application of Li mental anodes (LMA). Herein, we focus on the external fields involved during Li deposition, systematically summarizing the current progress of external field regulation for LMA. The mechanisms and limitations in regulating Li deposition are amply discussed. New perspectives and future research directions are also provided. With various external field being investigated and applied in Li metal anode system, it is expected that the dynamic regulation strategy can deliver great opportunities and promote the practical application of next-generation high-energy-density LMBs and other metal batteries.

金属锂电池中锂离子沉积的外场调节

锂（Li）金属因其理论比容量高、电化学电位低而被视为各种阳极中的 "圣杯"。然而，锂阳极在循环过程中会发生不可控制的枝晶生长和无限体积膨胀，严重阻碍了高能量密度锂金属电池（LMB）的商业化。考虑到锂沉积是一个动态的电化学过程，外部锉刀调节已成为促进锂心理阳极（LMA）循环性能和安全应用的热点策略。在此，我们将重点关注锂沉积过程中涉及的外场，系统地总结了目前 LMA 外场调控的研究进展。我们充分讨论了锂沉积调节的机制和局限性。同时还提供了新的视角和未来的研究方向。随着各种外场在金属锂阳极系统中的研究和应用，预计动态调节策略将带来巨大的机遇，并促进下一代高能量密度 LMB 和其他金属电池的实际应用。
