Li4Ti5O12 (LTO) is attractive alternative anode material with excellent cyclic performance and high rate after coating modifications of the conductive materials. Anatase TiO2 and glucose were applied of the synthesis of the carbon coated LTO (C@LTO). XRD results showed that all the major diffractions from the spinel structure of LTO can be found in the C@LTO such as (111), (311), (400) but there are no observations of the Carbon diffraction peaks. Electrochemical Impedance Spectroscopy (EIS) data shows C@LTO resistance was nearly half of the LTO value. Rate performance showed that capacity of C@LTO was higher than that of the pure LTO from 0.1 C, 0.2 C, 1 C, 2 C, 5 C and 10 C, which indicates that this is a promising approach to prepare the high performance LTO anode.
