Rechargeable aqueous zinc-ion batteries (RZIBs) provide a promising complementarity to the existing lithium-ion due their low cost, non-toxicity and intrinsic safety. However, Zn anodes suffer from zinc dendrite growth electrolyte corrosion, resulting in poor reversibility. Here, we develop an ultrathin, fluorinated two-dimensional porous covalent organic framework (FCOF) film as protective layer on surface. The strong interaction between fluorine (F) FCOF reduces surface energy of (002) crystal plane, enabling preferred planes during electrodeposition process. As result, deposits show horizontally arranged platelet morphology with orientations preferred. Furthermore, F-containing nanochannels facilitate ion transport prevent penetration for improving corrosion resistance. FCOF@Zn symmetric cells achieve stability over 750 h at ultrahigh current density 40 mA cm-2. high-areal-capacity full demonstrate hundreds cycles under high utilization conditions.

Lithium-sulfur (Li-S) batteries are held great promise for next-generation high-energy-density devices; however, polysulfide shuttle and Li-dendrite growth severely hinders their commercial production. Herein, a sulfonate-rich COF (SCOF-2) is designed, synthesized, used to modify the separator of Li-S batteries, providing solution above challenges. It found that SCOF-2 features stronger electronegativity larger interlayer spacing than none/monosulfonate COFs, which can facilitate Li+ migration alleviate formation Li-dendrites. Density functional theory (DFT) calculations in situ Raman analysis demonstrate possesses narrow bandgap strong interaction on sulfur species, thereby suppressing self-discharge behavior. As result, modified deliver an ultralow attenuation rate 0.047% per cycle over 800 cycles at 1 C, excellent anti-self-discharge performance by low-capacity 6.0% one week. Additionally, even with high-sulfur-loading cathode (3.2-8.2 mgs cm-2 ) lean electrolyte (5 µL mgs-1 ), still exhibit ≈80% capacity retention 100 cycles, showing potential practical application.
