Abstract
- Abstract: Ni doped titanate nanotubes were synthesized by hydrothermal method using Ni doped rutile TiO2 nanopowders as a starting material. The electrochemical properties were investigated by cyclic voltammmetric methods. The microstructure and morphology of the synthesized powders were characterized by XRD (X-ray diffraction), and HRTEM (high resolution transmission electron microscopy). Ni doped nanotubes were composed of H2Ti2O5·H2O with outer and inner diameter of ∼10nm and 6nm and showed a initial discharge capacity of 305mAh/g with poor cycling performance. However, after firing, the Ni doped nanotubes revealed better cycling performance due to lower reaction with hydrate and smaller diameter of the tubes. [Copyright &y& Elsevier]
