Functionalized multi-walled carbon nanotubes (CNTs) are homogeneously anchored with similar to 50 nm in size of Lithium titanate (Li4Ti5O12) by the controlled hydrolysis of tetrabutyl titanate. The resulted Li4Ti5O12/CNT composite has been investigated for electrochemical activity with lithium ion batteries, displaying high-rate capacity of 112 mAh g(-1) at 20 C. Furthermore, the composite exhibits good cycle stability, retaining over 98% of its initial capacity after 100 cycles at 5 C. The high capacity is attributed to the unique property of the Li4Ti5O12/CNTs nanocomposite, which provides a short diffusion path for lithium ions and rapid conducting for charge carrier through the high conductivity of CNTs network.
