Single crystalline Na2Ti3O7 rods were prepared through sintering a precursor synthesized in a reverse micelle. Charge/discharge measurements were performed in the potential range 0.01-2.5 V versus Na/Na+ under different C-rates. The tested capacity was maintained at 103 mA h g(-1), even after 20 cycles at a rate of 0.1 C. The results exhibited that the as-prepared single crystalline Na(2)Ti(3)O7 rods had a very low voltage plateau (around 0.3 V), and were suitable to use as anode materials for sodium-ion batteries.
