Ramsdellite type lithium titanate (Li2Ti3O7) powders were prepared by spray pyrolysis. Chemical and physical properties of Li2Ti3O7 powders were characterized by SEM, DTG, XRD and ICP. As-prepared Li2Ti3O7 precursor powders had a spherical morphology with hollow microstructure, but the irregular shaped morphology was obtained after the calcination above 900 °C. The crystal phase of ramsdellite Li2Ti3O7 was obtained by the calcination at 1100 °C. The first rechargeable capacities of Li2Ti3O7 anode were 168 mAh/g and 82 mAh/g at 0.1 mA/cm2 and 20 mA/cm2, respectively. The retention ratio of discharge capacity was 99 % at 1 mA/cm2 after 100th cycle. The cycle performance of Li2Ti3O7 anode had also high stability at 50 °C.
