Fluorination‐Tuned Covalent Organic Framework Interphases for Controllable LiF Content in Dendrite‐Free Lithium Metal Batteries
To tackle the challenge of precisely regulating LiF content within the solid electrolyte interphase (SEI) of high‐energy‐density lithium metal batteries (LMBs), this work presents a fluorination‐gradient design strategy, enabling controllable LiF formation through a covalent organic framework‐based artificial SEI layer...
