Carbon nanotubes enhanced Sb6O13 as a new anode material for sodium-ion batteries

Carbon nanotubes enhanced Sb6O13 as a new anode material for sodium-ion batteries Sb6O13/carbon nanotube (Sb6O13/CNT) composite prepared via a facile method has been evaluated as anode material for sodium-ion batteries. Its physical properties were investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Its electrochemical characteristics were studied via cyclic voltammetry (CV), electrochemical impedance spectra (EIS), and galvanostatic charge/discharge. Compared with Sb6O13, Sb6O13/CNTs showed an obviously enhanced electrochemical performance with an initial discharge capacity of 1048.7 mA h g−1, a reversible capacity of 308.7 mA h g−1 at 100 mA g−1 after 350 cycles. Even at 1000 mA g−1, a capacity of 158 mA h g−1 was obtained for Sb6O13/CNTs compared to 47 mA h g−1 of Sb6O13, which showed a good rate performance of Sb6O13/CNTs. In addition, the calculated sodium-ion diffusion coefficients of Sb6O13/CNTs reached 6.70 × 10−14 cm2 s−1, which was almost 47 times as much as that of Sb6O13. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Ionics Springer Journals

Abstract

Sb6O13/carbon nanotube (Sb6O13/CNT) composite prepared via a facile method has been evaluated as anode material for sodium-ion batteries. Its physical properties were investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Its electrochemical characteristics were studied via cyclic voltammetry (CV), electrochemical impedance spectra (EIS), and galvanostatic charge/discharge. Compared with Sb6O13, Sb6O13/CNTs showed an obviously enhanced electrochemical performance with an initial discharge capacity of 1048.7 mA h g−1, a reversible capacity of 308.7 mA h g−1 at 100 mA g−1 after 350 cycles. Even at 1000 mA g−1, a capacity of 158 mA h g−1 was obtained for Sb6O13/CNTs compared to 47 mA h g−1 of Sb6O13, which showed a good rate performance of Sb6O13/CNTs. In addition, the calculated sodium-ion diffusion coefficients of Sb6O13/CNTs reached 6.70 × 10−14 cm2 s−1, which was almost 47 times as much as that of Sb6O13.
