A facile in situ growth and subsequent compression strategy has been proposed to modify the separator. The in situ grown barrier layer is compact, lightweight and thin, exhibiting efficient physical/chemical entrapping capability on preventing the polysulfide shuttling. Applying this multi-functional separator, the CNT/S cathode with high sulfur content (75 wt%) delivers significantly improved long-term cycling performance with 0.056% capacity decay per cycle over 500 cycles.
