Alkali metals (Li, Na, and K) and multivalent metals (Zn, Mg, Ca, and Al) have become star anodes for developing high‐energy‐density rechargeable batteries due to their high theoretical capacity and excellent conductivity. However, the inevitable dendrites and unstable interfaces of metal anodes pose challenges to the safety and stability of batteries. To address these issues, covalent organic frameworks (COFs), as emerging materials, have been widely investigated due to their regular porous structure, flexible molecular design, and high specific surface area. In this minireview, we summarize the research progress of COFs in stabilizing metal anodes. First, we present the research origins of metal anodes and delve into their advantages and challenges as anodes based on the physical/chemical properties of alkali and multivalent metals. Then, special attention has been paid to the application of COFs in the host design of metal anodes, artificial solid electrolyte interfaces, electrolyte additives, solid‐state electrolytes, and separator modifications. Finally, a new perspective is provided for the research of metal anodes from the molecular design, pore modulation, and synthesis of COFs.

使用共价有机框架稳定高效可充电电池金属阳极的最新进展

碱金属（Li、Na和K）和多价金属（Zn、Mg、Ca和Al）由于其高理论容量和优异的导电性而成为开发高能量密度可充电电池的明星负极。然而，金属负极不可避免的枝晶和不稳定的界面对电池的安全性和稳定性提出了挑战。为了解决这些问题，共价有机框架（COF）作为新兴材料，由于其规则的多孔结构、灵活的分子设计和高比表面积而得到了广泛的研究。在这篇小综述中，我们总结了COF在稳定金属阳极方面的研究进展。首先，我们介绍了金属阳极的研究起源，并根据碱金属和多价金属的物理/化学性质深入探讨了它们作为阳极的优势和挑战。然后，特别关注COF在金属阳极、人造固体电解质界面、电解质添加剂、固态电解质和隔膜改性的主体设计中的应用。最后，从COF的分子设计、孔道调控和合成等方面为金属负极的研究提供了新的视角。
