Lithium-sulfur batteries have been regarded as the next-generation rechargeable batteries due to their high theoretical energy density and specific capacity. Nevertheless, the shuttle effect of lithium polysulfides has hindered the development of lithium-sulfur batteries. Herein, a novel zirconium-based metal-organic frame-work-801 film on carbon cloth was developed as a versatile interlayer for lithium-sulfur batteries. This interlayer has a hierarchical porous structure, suitable for the immobilization of lithium polysulfides and accommodating volume expansion on cycling. Moreover, the MOF-801 material is capable of strongly adsorbing lithium polysulfides and promoting their catalytic conversion, which can be enhanced by the abundant active sites provided by the continuous structure of the MOF-801 films. Based on the above advantages, the lithium-sulfur battery, with the proposed interlayer, delivers an initial discharge capacity of 927 mAh·g⁻¹ at 1 C with an extremely low decay rate of 0.04% over 500 cycles. Additionally, a high area capacity of 4.3 mAh·cm⁻² can be achieved under increased S loading.

锂硫电池由于具有较高的理论能量密度和比容量，被认为是下一代可充电电池。然而，多硫化锂的穿梭效应阻碍了锂硫电池的发展。在此，开发了一种新型的碳布上的锆基金属有机框架 801 薄膜，作为锂硫电池的多功能夹层。该夹层具有分层多孔结构，适用于多硫化锂的固定和循环时的体积膨胀。此外，MOF-801 材料能够强烈吸附多硫化锂并促进其催化转化，这可以通过 MOF-801 薄膜的连续结构提供的丰富活性位点来增强。基于以上优势，^-1在 1 C 下，在 500 次循环中具有 0.04% 的极低衰减率。此外，在增加 S 负载的情况下，可以获得 4.3 mAh·cm ^-2的高面积容量。
