In situ interface engineering of highly nitrogen-rich triazine-based covalent organic frameworks for an ultra-stable, dendrite-free lithium-metal anode

Highly N-rich triazine-based COFs as a multiple lithiophilic SEI layer is designed via in situ interface engineering, which induces uniform Li + flux and plating/stripping, decreases the Li + migration barrier, and suppresses Li-dendrite growth.
