英文摘要	Pure spinel-type lithium titanate, Li4Ti5O12, was successfully fabricated by a facile hydrothermal route using anatase TiO2 and LiOH solution as raw materials. The obtained samples were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and laser particle size distribution (PSD) analysis. The results showed that a spherical well-crystallized Li4Ti5O12 oxide was obtained at a calcination temperature of 800 degrees C. The optimal Li4Ti5O12 also has excellent electrochemical performance, which reached 162 mAh.g(-1) at a current density of 35 mA.g(-1) and a good rate capability with a capacity reached 124 mAh.g(-1) even at a current density of 720 mA.g(-1).
