Electrolyte Interphase Built from Anionic Covalent Organic Frameworks for Lithium Dendrite Suppression

Lithium (Li) metal batteries hold considerable promise for numerous energy‐dense applications. However, the dendritic Li anode produced during Li + /Li deposition‐stripping endangers battery safety and shortens cycle lifespan. Herein, an electrolyte interphase built from 2D anionic covalent organic frameworks (ACOF) is coated on Li for dendrite suppression. The ACOF with Li + ‐affinity facilitates rapid and exclusive passage of Li‐ions from the...
