Abstract
Designed as an anode material for sodium ion batteries, nitrogen-doped carbon sheets (NCSs) were successfully synthesized using graphene and dopamine as template and carbon precursor, respectively. The NCSs demonstrate high reversible capacity and excellent rate performance, delivering a high reversible capacity of 382 mAh gâ1 at 50 mA gâ1 after 55 cycles. Even up to 10 A gâ1, a rate capacity of 75 mAh gâ1 can be obtained. Furthermore, NCSs also have remarkable cycling stability with specific capacity of 165 mAh gâ1 after 600 cycles (under 200 mA gâ1). The excellent performance of NCSs can be ascribed to the nitrogen-doped two-dimension sheet structure.
