摘要：
Reduced graphene oxide coated porous SnO2 nanotubes are designed as anode for sodium ion batteries (SIBs). The nanocomposites deliver good cycling stability with the capacity retention of 91% extending to 100 cycles at a current density of 50 mA g(-1) in the voltage range of 0.01-3.0 V. Moreover, they reveal good rate capability with the reversible capacities of 242.6, 207.7, 173.4, and 140.3 mAh g(-1) at various current densities of 50, 100, 200, and 400 mA g(-1), respectively. These results indicate that the coating of reduced graphene oxide is an effective strategy to buffer volume change and improve charge transfer resistance during Na+ ion insertion/extraction for SIBs.
