Developing the conductive and catalytic composite interface is an efficient way to boost up the conversion of lithium polysulfide (LiPSs) that can effectively resolve the shuttle effect. Besides, achieving the high performance with low metal loading has practical significance for the commercialization of lithium–sulfur (Li−S) batteries. Herein, the chainmail catalyst of Fe3O4@C/CNTO was prepared by annealing the iron phthalocyanine (FePc)/oxidized carbon nanotubes (CNTO) precursor in which FePc was used as iron and carbon sources and CNTO was functionalized as oxygen source and catalyst support. The conductive composite catalyst with low metal loading (5.4 wt%) was applied into the coating layer of Celgard separator with duplex functions in trapping and catalyzing intercepted LiPSs for high‐performance Li−S batteries. This work can help us to understand the importance of conductive and catalytic composite interface for promotion of LiPSs conversion and also offer a more feasible synthesis method of electrocatalyst for other energy storage systems.

Fe3O4 @ C / CNTO改性的Celgard隔膜的链锁催化剂，具有低金属负载，适用于高性能锂硫电池
开发导电和催化复合材料界面是提高多硫化锂（LiPSs）转化率的有效方法，可以有效解决穿梭效应。此外，在低金属负载下实现高性能对于锂硫（Li-S）电池的商业化具有实际意义。在此，Fe 3 O 4的链状催化剂通过将铁酞菁（FePc）/氧化碳纳米管（CNTO）前体进行退火来制备@ C / CNTO，其中FePc被用作铁和碳源，CNTO被功能化为氧源和催化剂载体。将具有低金属负载量（5.4 wt％）的导电复合催化剂应用于具有双重功能的Celgard隔膜的涂层中，以捕获和催化高性能Li-S电池的截留LiPS。这项工作可以帮助我们理解导电和催化复合界面对于促进LiPSs转化的重要性，并为其他储能系统提供一种更可行的电催化剂合成方法。
