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

Li 4 Ti 5 O 12 /V 2 O 5 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 Li 4 Ti 5 O 12 /V 2 O 5 composites with different nano size were successfully synthesized. The Li 4 Ti 5 O 12 /V 2 O 5 sample (2 wt% V 2 O 5 addition of Li 4 Ti 5 O 12 ) keep at a high discharge capacity of 169.9 mAh g − 1 after 150 cycles at 1 C. The existence of the V 2 O 5 reduces the size of Li 4 Ti 5 O 12 , which improve the electrochemical activity of the sample.
