Lithium‐sulfur batteries (LSBs) have attracted the battery community's attention in recent years because of the ultra‐high theoretical specific capacity and energy density. To realize the commercial application of LSBs, issues including lithium polysulfide shuttle effects, insulating active materials, and large volume changes are urgently to be solved, especially LSBs with high sulfur loading suffering from more serious capacity fading. Developing environmentally friendly and multifunctional binders would not only overcome the problems existing in LSBs but could also satisfy the requirements for green materials. In this Review, we first conclude the required characteristics for binders in LSBs, then summarize the research progress of ecofriendly binders in detail, as well as outstanding binders applied in high‐sulfur‐loading electrodes. Finally, the challenges and development direction of binders for future industrial applications in LSBs are also highlighted.

锂硫电池环保粘合剂

锂硫电池（LSB）近年来因其超高的理论比容量和能量密度而引起了电池界的关注。为了实现LSB的商业应用，迫切需要解决多硫化锂穿梭效应，绝缘活性材料和体积变化大的问题，尤其是高硫负荷的LSB会遭受更严重的容量衰减。开发环保和多功能的粘合剂不仅可以解决LSB存在的问题，还可以满足对绿色材料的要求。在本综述中，我们首先总结了LSB中粘合剂的要求特性，然后详细总结了环保粘合剂的研究进展以及在高硫负载电极中应用的杰出粘合剂。
