Polysulfide intermediates (PSs), the liquid‐phase species of active materials in lithium–sulfur (Li‐S) batteries, connect the electrochemical reactions between insulative solid sulfur and lithium sulfide and are key to full exertion of the high‐energy‐density Li‐S system. Herein, the concept of sulfur container additives is proposed for the direct modification on the PSs species. By reversible storage and release of the sulfur species, the container molecule converts small PSs into large organosulfur species. The prototype di(tri)sulfide‐polyethylene glycol sulfur container is highly efficient in the reversible PS transformation to multiply affect electrochemical behaviors of sulfur cathodes in terms of liquid‐species clustering, reaction kinetics, and solid deposition. The stability and capacity of Li‐S cells was thereby enhanced. The sulfur container is a strategy to directly modify PSs, enlightening the precise regulation on Li‐S batteries and multi‐phase electrochemical systems.

工作锂-硫电池中的硫磺容器实现的直接中间法规。

多硫化物中间体（PSs）是锂硫（Li‐S）电池中的活性物质的液相物质，它连接绝缘的固体硫与硫化锂之间的电化学反应，并且是充分发挥高能密度锂的关键‐S系统。在此，提出了硫容器添加剂的概念以直接改性PSs。通过硫物质的可逆存储和释放，容器分子将小的PS转化为大的有机硫物质。原型二（三）硫醚-聚乙二醇硫容器在可逆PS转化中非常有效，可以在液体种类聚集，反应动力学和固体沉积方面对硫阴极的电化学行为产生多重影响。从而增强了锂电池的稳定性和容量。
