The Cover Feature shows a 2‐dimensional g‐C3N4/graphene sheet complex interlayer for a sulfur/carbon cathode. The thin barrier layer with the laminated‐structure channels acts likes a shark net to block the polysulfide species (Li2Sx, 2<x≤8, the big sharks) shuttling via physical and chemical interactions, but also to protect lithium‐ion (Li+, the little fishes) migrating from the cathode to the anode.
