摘要：

TiO2@Sn core-shell nanotube material prepared by thermal decomposition of SnCl4 on TiO2 nanotubes at 300 degrees C has been demonstrated superior Li-ion storage capability of 176 mA h/g even at high current rate of 4000 mA/g (charge and discharge of all TiO2 within 5 min) in spite of using low carbon content (5 wt%). This value corresponds to volumetric energy densities of 317 mA h/cm(3), and its value was 3.5-fold larger than that of the bare TiO2 nanotubes. (C) 2008 Elsevier B.V. All rights reserved.
