A custom single-wall carbon nanotube (SWCNT)-modulated separator is employed to directly suppress the polysulfide migration and indirectly protect the lithium-metal anode from severe polysulfide contamination. The conductive sp2-carbon scaffold continuously reactivates and reutilizes the trapped active material, so the SWCNT-modulated separator provides a facile way to facilitate the implementation of pure sulfur cathodes with high sulfur contents and loadings.
