| Abstract: | Lithium titanate was synthesized by one step hydrothermal method and its performance was studied. The cycle preparation process was shortened and no other reagents were used by this method compared with the conventional hydrothermal synthesis method. Moreover, this method used much less raw materials and had less environmental pollution. The results showed that the prepared sample had a discharge specific capacity of 163mAh/g at 0.1C rate and the initial efficiency was nearly 100%.The XRD pattern of the sample was consistent with the standard card, and it had a regular and uniformly particles distribution. The lithium titanate had a good charge/discharge reversibility by cyclic voltammetry analysis. |
