The shuttle of polysulfides between cathode and anode induces low capacity and poor cycling life in lithium‐sulfur batteries. As shown in article number 1500268, J.‐Q. Huang, Q. Zhang, and co‐workers propose a Janus separator—fabricated from polypropylene supported cellular graphene—to promote the utilization and stability of a sulfur cathode by reactivating the non‐active separator/cathode interphase.
