A Facile Synthesis and Characterization of Titanium Dioxide as Negative Electrode Material for Lithium Ion Batteries

A green and friendly synthesis method was used to prepare Anatase TiO2and the electrochemical performances of this metal oxide as negative electrode for lithium ion batteries were studied. X-Ray diffraction analysis confirm the formation of Titanium Oxide with anatase type structure with a small content of brookite phase. The spherical shape of the particles is clearly highlighted using Scanning Electron Microscopy. The prepared TiO2electrode delivers a discharge capacity of 290 mAh g-1in the first cycle under C/10 current rate. Indeed, a coulombic efficiency higher than 95 and a capacity retention of 85% is obtained after 100 cycles.
