Covalent organic frameworks (COFs) have shown promise as bifunctional catalysts to simultaneously mitigate shuttle effects and Li dendrite issues of lithium–sulfur (Li–S) batteries. However, the inherent low conductivity COFs has significantly limited their catalytic activity stability. Herein, durability COF/MXene heterostructure are activated by tuning surface curvatures interfaced with MXene. The increased curvature could induce enhanced electron delocalization alter geometry, which in turn strengthens lithium polysulfide adsorption, lowers energy barriers, stabilizes sites promote sulfur redox reactions. Concurrently, hierarchical structure improves electrolyte penetration wettability, facilitates rapid ion transport, homogenizes Li-ion flux distribution, thus achieving uniform deposition. Consequently, 1D-COF/MXene Li–S batteries demonstrate a high-rate capacity 926 mA h g–1 at 4C, stable cycling performance reversible 589 3C after 500 cycles, high 604 cm–2 loading 3.5 mg under electrolyte-to-sulfur ratio 10 μL mg–1.

Abstract Lithium (Li) metal is a promising anode material for next‐generation high‐energy‐density batteries. However, safety concerns and the limited lifespan due to Li dendrite formation hinder its practical application. The complex process involves nonuniform nucleation radial growth, requiring holistic strategy simultaneously regulate both processes. In this work, dual‐aspect control developed by designing protective layer composed of hydroxyapatite (HA) liquid crystal polymer (LCP). Electrochemical, microstructural, computational analyses revealed that HA provides homogenous 0 adsorption sites, enhancing kinetics uniformity. Meanwhile, LCP self‐assembles into cation‐selective channels, promoting Li‐ion diffusion regulating growth direction. This significantly improved plating mitigated formation. Benefiting from strategy, symmetric cell achieved critical current density 5 mA cm −2 maintained 500 h at 3 . Furthermore, in Li–sulfur batteries, exhibited exceptional high‐rate cycling performance (>10 ) with an average capacity decay rate only 0.056% over 1000 cycles. These results highlight effectiveness suppressing dendrites improving stability.
