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