粘合剂作为锂硫电池不可或缺的组成部分之一，对电池性能影响很大。在此，我们报告了一种新型多功能超分子共晶液体（SEL）粘合剂，由二苯胺（DP）和二苯甲酮（BP）组成，它能够显着改善高性能锂硫电池的导电网络和锚定多硫化物。与传统的聚偏二氟乙烯（PVDF）粘合剂相比，SEL粘合剂在机械性能和容量保持率（1C下200次循环后83%）方面均表现出显着改善。
As one of the indispensable components in lithium-sulfur batteries, the binders greatly impact battery performance. Herein, we report a new multifunctional supramolecular eutectic liquid (SEL) binder, consisting of diphenylamine (DP) and benzophenone (BP), which enables a strongly improved conductive network and anchored polysulfides for high-performance lithium-sulfur batteries. Compared with the traditional polyvinylidene fluoride (PVDF) binder, the SEL binder demonstrates remarkable improvement in both the mechanical performance and the capacity retention (83% over 200 cycles at 1C).
