Abstract

The sodium titanate nanorods were synthesized via hydrothermal reaction in NaOH solution. Then the Li-Ti-O compound nanorods were prepared by a molten salt method in molten LiNO₃, which was involved in the ion-exchange process, and by calcination at 400-700°C in air. It is found that Li-Ti-O compound was of nanorod morphology and underwent a phase transition to a mixture of Li-poor anatase Li_xTiO₂ and spinel Li₄Ti₅O₁₂. The electrochemical lithium storage property was tested by constant current charge/discharge. Results demonstrate that the Li-Ti-O compound nanorods calcined at 600°C have excellent specific capacity, good reversibility and high rate discharge capability.
