摘要

Cathodes prepared using grapheme nanosheets (GNSs), nitrogen-doped graphene nanosheets (N-GNSs), exfoliated nitrogen-doped grapheme nanosheets (Ex-N-GNSs) as well as composite of Ex-NGNSs with lithium aluminum germanium phosphate (LAGP) have been explored for application in lithium-oxygen batteries. These cathodes exhibit remarkable enhancement in cell capacity in comparison to conventional carbon cathodes. This enhancement is ascribed to the unique morphology of GNSs, higher oxygen reduction and oxygen evolution activity as well as fast lithium ion conduction of LAGP. These results demonstrate a strong potential of GNSs as cathodes for rechargeable lithium-oxygen batteries.
