Abstract

The Li4Ti5O12/G/CNTs hybrid material was synthesized via a facile rheological phase reaction route. For comparison, the Li4Ti5O12/G hybrid material was also prepared using the similar rheological phase method. The results showed that the Li4Ti5O12/G/CNTs had better rate capability and cycling performance than that of the Li4Ti5O12/G. At 0.2C, the initial discharge capacity of the Li4Ti5O12/G/CNTs was 172mAh/g, and even at the high rate of 5.0C and 10.0C, it could still remain at 150mAh/g and 144mAh/g, respectively. Moreover, only less than 6% discharge capacity loss over 100 cycles at 10.0C was observed. The outstanding electrochemical performances make it a promising anode material for high rate lithium ion batteries.
