An enhanced electrochemical performance of a sodium-air battery with graphene nanosheets as air electrode catalysts.

Graphene nanosheets (GNS) were employed as an air electrode for a sodium-air battery (SAB). High discharge capacity of 9268 mA h g(-1) with low overpotential was achieved, indicating its superiority to a normal carbon film electrode. Our results indicate that GNS as air electrodes could improve the electrochemical performance of rechargeable SABs.
