Abstract

A phase-pure Li4Ti5O12/reduced graphene oxide nanocomposite was prepared using a simple one-pot synthesis of the Li-Ti-O precursor and subsequent heat treatment. The prepared nanocomposite delivers a reversible capacity of 168 mA h g-1 at 1 C-rate and a remarkable rate capability with 59% capacity retention at 50 C-rate.
