“…Figure and Table S1 (Supporting Information) exhibit the comparison of the battery performance of Li–S cells using various bio‐based polymer binders and commercial polymer binder . The Li–S cell using Chi–rGO–1 binder showed high stability at 1 C, and a capacity decay retention per cycle as low as 0.016%, which showed dramatically enhanced battery performance, compared to other Li–S cells using bio‐based polymer binders and commercial polymer binders (PAA, PVDF, SBR:CMC, and LA‐132).…”

Although Li–S batteries are currently receiving great interest, due to their high energy density and the low cost of sulfur, practical applications are still inhibited by capacity fading that is caused by various undesirable processes. In this study, a new multifunctional network binder composed of chitosan and reduced graphene oxide (rGO) is introduced to enhance the capacitive performance of Li–S batteries. Chitosan is reacted with graphene oxide in aqueous solution to produce a homogenous network, which effectively enhances the redox system by entrapping lithium polysulfides, reinforces the mechanical properties, and allows electrical conductivity through the binder system. Collaborative relationship‐based chitosan–rGO network binder allows noteworthy improvement in the capacity decay of 0.016% per cycle at 1 C for 1000 cycles.

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.

“…According to the previous reports, the crosslinked polymer with multiple functional groups can effectively mitigate the volume expansion and limit the shuttle of lithium polysulfides and, consequently, significantly improve the performance of Li-S batteries, especially for high sulfur loading. [16,28,34,35] For instance, Yan and co-workers [36] synthesized a new binder via copolymerization of hexamethylene diisocyanate with polyethyleneimine (PEI) to form a network structure with high proportion of amine groups. Moreover, the sulfur loading areal capacity can reach 7.9 mAh cm −2 , and the capacity retention is 91.3% over 600 cycles at 2C.…”

Owing to the negative impact of the extensive utilization of batteries on the environment, sustainability of the cells needs to be included in the systemic research of batteries. Herein, a dissolvable ionic crosslinked polymer (DICP) is exploited as a binder for lithium–sulfur batteries by crosslinking the polyacrylic acid and polyethyleneimine through carboxy‐amino ionic interaction. This interaction is pH‐controlled, and therefore, the crosslinked binder network can be readily dissociated under basic conditions, providing a facile strategy enabling valuable components recycled through a convenient washing method. The sulfur cathode prepared using the recycled carbon–sulfur composite can deliver comparable capacity as that of fresh electrode. In addition, evidence from cell performance and characterizations, such as in situ X‐ray absorption spectroscopy, in situ UV–visible spectroscopy, X‐ray photoelectron spectroscopy, and density functional theory calculation, confirms that DICP is a more effective binder than its commercial counterpart on suppressing polysulfide dissolution in the electrolyte. Exploiting reversible crosslinked polymer binder for recyclable Li–S batteries with ameliorated electrochemical performance, this study illuminates sustainable development for large‐scale energy storage systems.
