The sluggish sulfur redox kinetics and shuttle effect of lithium polysulfides are recognized as the main obstacles to the practical applications of lithium–sulfur (Li-S) batteries. In their Research Article (e202306901), Dan Luo, Zhongwei Chen et al. report a novel dual-defect metal–organic framework (MOF) as a new catalyst type to achieve synergistic catalysis for the multi-step conversion reaction of lithium polysulfides. The missing linker defect and missing cluster defect significantly catalyze the sulfur reduction reaction. As a result, dual-defect MOF-based separators lead to a strongly improved electrochemical performance of Li-S batteries.

金属有机骨架催化剂的双重缺陷加速锂硫电池中的多步硫氧化还原反应

多硫化锂缓慢的硫氧化还原动力学和穿梭效应被认为是锂硫（Li-S）电池实际应用的主要障碍。Dan Luo、Zhongwei Chen 等人在他们的研究文章 (e202306901) 中。报告了一种新型双缺陷金属有机骨架（MOF）作为一种新的催化剂类型，以实现多硫化锂多步转化反应的协同催化。缺失的连接子缺陷和缺失的簇缺陷显着催化硫还原反应。因此，基于双缺陷 MOF 的隔膜显着改善了锂硫电池的电化学性能。
