The cover picture shows that the chainmail catalyst of Fe 3 O 4 @C/CNTO (CNTO=oxidized carbon nanotubes) with low metal loading was innovatively constructed and applied into the coating layer of a Celgard separator for Li‐S battery. Fe 3 O 4 serves as the active site to promote the interconversion of lithium polysulfides; the carbon‐shell‐encapsulated Fe 3 O 4 leads to an integrated 3D architecture with the CNTO support to provide a continuous pathway for facile electron transport. Benefiting from the catalytic and conductive composite interface, the battery with the Fe 3 O 4 @C/CNTO‐modified separator delivers a satisfactory specific capacity and excellent stability.
