Preparation and Electrode Formulations of Lithium Titanate

In this paper,lithium titanate anode materials were prepared by high temperature solid state synthesis.The phase and morphology of the obtained lithium titanate were characterized by X-ray diffraction（XRD） and scanning electron microscopy（SEM）,respectively.Three different electrode formulations were used to assemble coin cells,for measuring the capacity,ratio,cycle and AC impedance of the anode materials.The electrochemical performances of LTO-1 electrode were found to be the best,with 97.7% of capacity retention after 100 cycles at 1C of ratio and 147.7 mAh/g of discharge capacity at 8C of ratio.
