Synthesis and Electrochemical Performances of Nanoscale TiO₂ as Anode Material for Lithium Ion Batteries

Abstract

The nanoscale TiO2 was synthesized and their electrochemical properties as the anode electrode materials for rechargeable Li-ion batteries were measured. The structure, morphology and electrochemical properties of the nanoscale TiO2 composites synthesized were characterized in detail by X-ray (XRD), Transmission Electron Microscopy (TEM) and electrochemical measurement. The first discharge capacities were 126 mAh/g for the nanoscale TiO2 at the current density of 100 mA/g at ambient temperatures. The specific capacities were stabilized at around 57mAh/g after 20 cycles.
