Li4Ti5O12 was obtained by solid-state reaction of a ternary precursor mixture, TiO2, Li2CO3 and carbon. The influences of the reaction time, temperature and mixing method on the electrochemical performance of Li4Ti5O12 were investigated. Electrochemical measurements and XRD diffraction characterization were used to determine the reversible capacity and TiO2 residue in the final powder, respectively. Between 1.2 and 2.0V versus Li, a reversible capacity as high as 165mAh/g at 7.3mA/g was obtained.
