A solid electrolyte interphase (SEI) on a sodium (Na) metal anode strongly affects the Na deposition morphology and the cycle life of Na metal batteries (SMBs). SMB applications are hindered by an unstable SEI and dendrite growth on the Na anode surface, which directly cause low coulombic efficiency and can even lead to safety issues. An artificial interface layer can stabilize Na metal anodes, be easily tailored, and is barely affected by electrochemical processes. In this review, recent advances that support the stability of working Na metal anodes are focused via artificial interphase engineering of inorganic materials, organic materials, and organicâ€“inorganic composite materials, with an emphasis on the significance of interface engineering in SMBs. Fundamental investigations of artificial interphase engineering are also discussed on Na metal anodes and some recent research is summarized to enhance the interface between Na metal and electrolytes using an artificial interface layer. The prospects for interphase chemistry for Na metal anodes are provided to open a way to safe, high-energy, next-generation SMBs.

稳定钠金属阳极人工界面工程的最新进展

钠 (Na) 金属负极上的固体电解质界面 (SEI) 强烈影响钠沉积形态和钠金属电池 (SMB) 的循环寿命。SMB应用受到钠阳极表面不稳定的SEI和枝晶生长的阻碍，直接导致库仑效率低，甚至可能导致安全问题。人工界面层可以稳定钠金属阳极，易于定制，并且几乎不受电化学过程的影响。在这篇综述中，支持工作钠金属阳极稳定性的最新进展集中在无机材料、有机材料和有机-无机复合材料的人工界面工程，重点是界面工程在 SMB 中的重要性。还讨论了关于钠金属阳极的人工界面工程的基础研究，并总结了一些最近的研究，以使用人工界面层增强钠金属和电解质之间的界面。为钠金属阳极的界面化学提供了前景，为安全、高能的下一代 SMB 开辟了道路。
