In recent years, Lithium-sulfur (Li-S) batteries have great potential to replace lithium as one of the new generation energy storage devices due their high density, environmental friendliness, abundant natural resources and low cost. However, there is a serious polysulfide "shuttle phenomenon" in Li-S batteries, which greatly leads loss battery capacity reduction coulomb efficiency. Based on above, novel tungsten carbide (WC)-modified nitrogen-doped carbon nanotubes/nickel composite (N-CNTs/Ni@WC) was synthesised under argon atmosphere this paper. The nanotubes functioned physical barriers inhibit shuttling LiPSs, while highly polar WC Ni nanoparticles chemically adsorbed LiPSs simultaneously exerted catalytic effect induce Li2S deposition facilitate redox reaction. addition, N-CNTs, ionic conductivity, favour fast ion transport. Because these features, basis modified N-CNTs/Ni@WC separators show initial discharge (1139.56 mAh g-1 at 0.5 C current density), efficiency (close 100% after 500 cycles 1 C), decay rate (0.08 for with C). conclusion, work offers method optimising preparation design materials lithium-sulfur reliable way.

Abstract Incorporating inorganic nanostructured materials into polymeric separators for lithium‐ion batteries (LIBs) enhances properties such as ionic conductivity, electrolyte wettability, and thermal resistance. However, poor interfacial compatibility between the matrix remains a significant challenge. In this study, Zr‐based UiO‐66 metal‐organic frameworks (MOFs) is employed an binder halloysite nanotubes (HNTs) poly‐(arylene ether benzimidazole) (OPBI) matrix, preparing porous using non‐solvent phase separation (NIPS) method. The MOFs promote strong adhesion of HNTs to OPBI chains, creating more cohesive inorganic‐organic system, confirmed by molecular dynamics (MD) simulations binding energy. resulting OPBI@M‐H10 composite separator exhibits high porosity (80%), absorption capacity 377%, conductivity 1.59 mS·cm⁻¹. Furthermore, LiFePO 4 half‐cells assembled with show discharge 161 mAh·g⁻¹ retention rate 97.96% after 200 charge‐discharge cycles. also demonstrates excellent electrode stability in plating/stripping test Li symmetric cells, lasting up 1600 hours effectively inhibiting dendrite growth on anode. This approach provides promising solution high‐performance LIBs paves way advancements technology energy storage applications.
