Abstract

A space-confined “sauna” reaction system is introduced for the simultaneous reduction and functionalization of graphene oxide to unique graphene–sulfur hybrid nanosheets, in which thin layers of amorphous sulfur are tightly anchored on the graphene sheet via strong chemical bonding. Upon being used as the cathode material in lithium–sulfur batteries, the as-synthesized composite shows an excellent electrochemical performance.
