摘要：

Nanostructured lithium titanate (Li4Ti5O12) nanopowder was successfully synthesized by simple peroxide route using titanium oxysulphate and lithium hydroxide. The structural properties of the as-prepared and sintered powders were characterized by using powder X-ray diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy. Surface morphological property was studied by scanning electron microscope. Compositional analysis was studied using X-ray photo electron spectroscopy. The thermal degradation behavior of the as-synthesized materials was analyzed by thermo gravimetric analysis (TG-DTA). The electrochemical properties of the Li4Ti5O12 nanopowders were examined using galvanostatic charge/discharge test. The effect of sintering temperature on its various physical properties and the electrochemical performances of Li4Ti5O12 was investigated. The storage capacity value obtained for Li4Ti5O12 and Li4Ti5O12/graphite composite anode was 83.52 and 91.33 mAhg(-1) in 1 M LiPF6 at 0.1 mA.
