High performance supercapacitors based on highly conductive nitrogen-doped graphene sheets

Abstract

Thermal nitridation of reduced graphene oxide sheets yields highly conductive (∼1000–3000 S m−1) N-doped graphene sheets, as a result of the restoration of the graphene network by the formation of C–N bonded groups and N-doping. Even without carbon additives, supercapacitors made of the N-doped graphene electrodes can deliver remarkable energy and power when operated at higher voltages, in the range of 0–4 V.
