High rate performances of hydrogen titanate nanowires electrodes

In this study, H2Ti3O7 nanowires were successfully synthesized via a hydrothermal process and post-treatments. The diameter of the nanowires is found to be about 30 nm and the length up to several micrometers. A lithium battery using H2Ti3O7 nanowires as the active material of the positive electrode exhibits a discharge capacity of 100 mA hg(-1) and still keeps stable after 200 cycles at a current density as high as 40 Ag-1, demonstrating excellent high rate performance.
