Abstract

The micrometer-scale reticulated structure of highly sulfur-philic nitrogen-doped graphene oxide (NrGO) that is achieved by chemically controlling the nitrogen-doping degree improves the chemical and electrochemical stability of the active sulfur while providing sufficient sulfur/electrolyte interface for a facile electrochemical process so that a high specific energy of 325 W h kg−1 can be achieved.
