In situ anchoring 2D hexagonal Zn-MOF on MXene toward robust anode-less 5 V-class Li metal batteries.

ABSTRACT: Anode-less 5 V-class lithium metal batteries (LMBs) promise high energy density and safety yet, in practice, face critical challenges including dendrite growth, interfacial instability, pulverization associated with "dead" lithium accumulation, and energy density compromise from the use of heavy copper collector. Here, we demonstrate an elaborate design of two-dimensional hexagonal zinc-containing metal-organic framework anchored on conductive titanium carbide (Ti₃C₂T_x) MXene sheets (MX/2D-Zn-MOF) as a three-dimensional lightweight host for anode-less 5 V-class LMBs. The abundant nitrogen/fluorine/zinc-rich lithiophilic sites effectively decrease lithium nucleation energy barriers, ensure uniform lithium deposition, and stabilize solid electrolyte in
