Anode material Li4Ti5O12 was prepared by the method of solid-state reaction at high temperature. In the experiment, it was utilized by undoping and a small amount of Mg2+ doping with raw material respectively. The morphology of powder was observed by scanning electron microscopy (SEM), the phase analysis was done by X-ray diffraction analysis (XRD), and the charging and discharging tests with constant current were also carried out at room temperature. The results showed that little effect was on the particle size by a small amount of Mg2+ doping, the change of the structure of the powder material was not caused, but the conductivity of Li4Ti5O12 anode material was increased, the capacity and stability of the charging and discharging cycles were raised. It fully proved that Mg2+ doping was relatively effective. Keywords: Li-ion battery;lithium titanate (Li4Ti5O12); doping;charging and discharging. |
