Ladder-type phenazine-linked covalent organic polymers with synergistic cation-π interactions for highly stable lithium metal batteries.

ABSTRACT: The construction of an efficient regulating film for lithium metal anodes, capable of addressing both dendritic growth and by-product reactions, is pivotal to the stability of lithium metal batteries. Herein, a ladder-type phenazine-linked covalent organic polymer (PZ-CHPT) with a fully extended two-dimensional aromatic π-conjugated system, enriched with nitrogen sites (C-C[double bond, length as m-dash]N-C linkages, C[double bond, length as m-dash]N units), is introduced as a lithium metal anode protective layer to control spatial ion flux and induce uniform charge distribution, aiming at enhancing the reliability of lithium metal batteries. Remarkably, the incorporation of rigid heterocyclic units into PZ-CHPT boosts interfacial stability through reinforced covalent linkage strength and
