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 sp 2 ‐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.
