Catalytic Effects of Heteroatom-doped Graphene Nanosheets on the Performance of Li-O2Batteries

Year: 2014

Type: article

Abstract: Graphene nanosheets (GNS), nitrogen-doped graphene nanosheets (N-GNS), and sulfur-doped graphene nanosheets (S-GNS) were successfully synthesized, and their catalytic effects on the oxygen reduction reaction (ORR) in Li-O 2 batteries were compared.The S-GNS electrode exhibited the highest ORR catalytic activity, resulting in enhanced discharge capacity and power capability.We attributed the enhanced ORR catalytic activity to the increased defect sites on graphene.
