| Popis: | Nitrogen-doped carbon nanotubes (N–C NTs) have been fabricated through a facile carbonization of polypyrrole nanotubes templating from FeOOH nanorods, and have been applied as an anode material for sodium-ion batteries (SIBs). Owing to their unique structural and compositional features, the N–C NTs electrode exhibits high reversible capacities and excellent cycling stability, and high rate capability. For example, the N–C NTs electrode can deliver a capacity of 248.5 mAh/g at a current density of 100 mA/g after 250 cycles. Moreover, the capacity fading is only 0.13% per cycle from 2 to 250 cycles. Such an excellent sodium-storage performance implies that the as-prepared N–C NTs have a bright application prospect as a high-capacity, long-life, and high-rate anode material for advanced SIBs. |
