Synthesis of Li4Ti5O12/V2O5 nanocomposites for lithium-ion batteries by one-pot co-precipitation method

Li4Ti5O12/V2O5 nanocomposites were synthesized by one-pot co-precipitation method. The structure and morphology of the as-prepared materials were analyzed by X-ray diffraction and transmission electron microscopy. The results show that Li4Ti5O12/V2O5 composites with different nano size were successfully synthesized. The Li4Ti5O12/V2O5 sample (2 wt% V2O5 addition of Li4Ti5O12) keep at a high discharge capacity of 169.9 mAh g(- 1) after 150 cycles at 1 C. The existence of the V2O5 reduces the size of Li4Ti5O12, which improve the electrochemical activity of the sample.
