Graphical abstractN,S-codoped sponge-like graphene, which presents a high reversible capacity to offer extra capacity, and contains rich doping heteroatoms to restrict the dissolution of polysulfide, is used as electroactive interlayer for Li–S batteries. By this method, the sulfur cathode shows an ultrahigh discharge capacity and superior high rate performance.
