Hollow carbon nanowires (HCNWs) were prepared through pyrolyzation of a hollow polyaniline nanowire precursor. The HCNWs used as anode material for Na-ion batteries deliver a high reversible capacity of 251 mAh g -1 and 82.2% capacity retention over 400 charge-discharge cycles between 1.2 and 0.01 V (vs Na +/Na) at a constant current of 50 mA g -1 (0.2 C). Excellent cycling stability is also observed at an even higher charge-discharge rate. A high reversible capacity of 149 mAh g -1 also can be obtained at a current rate of 500 mA g -1 (2C). Th...
