Achieving burst Li⁺ channels via quasi-two-dimensional fluorinated metal-organic framework modulating functionalized interface.

ABSTRACT: The development of disordered Li dendrite and the adverse reaction between Li and electrolyte impede practical use of Li metal batteries (LMB). Herein, we propose quasi-two-dimensional fluorinated metal-organic framework carbon (q2D-FcMOF) that is utilized to construct artificial solid electrolyte interface (ASEI) to achieve robust interfacial protective double-layer. The outer organic layer provides ample space for Li deposition, while the inner inorganic LiF layer promotes conduction of Li⁺ and blocks electron transport. Metal clusters within the hybrid layer are uniformly dispersed, encouraging Li⁺ to cluster around metal active sites that are thermodynamically compatible with Li. Consequently, q2D-FcZ8@Li symmetrical batteries demonstrate an ultralong cycle life o
