Abstract:The practical usage of Na metal anode is severely prohibited by the instability of the natively formed solid electrolyte interface (SEI) layer and the uncontrollable Na dendrite growth, inducing short cycle life and serious safety concerns. Herein, phosphorylated covalent organic frameworks (P‐COF) is first synthesized and rationally used to construct the robust artificial interface layer for Na metal stabilization. The modified Na metal anode demonstrates high rate performance (5 mA cm−2) and ultralong cyclin… Show more
