Abstract

Abstract: 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. Abstract : Environmentally friendly binders : Research and development activities for environmentally friendly binders are reviewed, featuring those with the ability to overcome one or more the current issues existing for lithium‐sulfur batteries, including lithium polysulfide dissolution and shuttling, electronic and ionic insulation of active materials, volume expansion, and electrode destruction.
