Lithium–sulfur (Li–S) batteries are one of the most suitable energy storage devices for electronic requirements due to their high energy density and specific capacity. In the past decades, many researchers have devoted themselves to developing high performance Li–S batteries. However, the application of LiS batteries continues to be hindered because of the severe polysulfide migration upon electrochemical cycles. In this work, novel starfish‐like Molybdenum carbide (Mo₂C) framework was prepared and used as cathode host materials for sulfur. Due to the presence of the Mo₂C framework, the polysulfide migration can be efficiently inhibited.

新型海星状Mo2C框架可作为高效电化学宿主，用于高性能的锂硫电池

锂硫（Li–S）电池因其高能量密度和比容量而成为最适合电子需求的储能设备之一。在过去的几十年中，许多研究人员致力于开发高性能的Li-S电池。然而，由于电化学循环中多硫化物的严重迁移，LiS电池的应用继续受到阻碍。在这项工作中，制备了新颖的海星状碳化钼（Mo ₂ C）框架并将其用作硫的阴极主体材料。由于Mo ₂ C骨架的存在，可以有效地抑制多硫化物的迁移。
