摘要：

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).
