Li4Ti5O12/reduced graphite oxide nano-hybrid material for high rate lithium-ion batteries

A spinel Li4Ti5O12 nanoplatelet/reduced graphite oxide nano-hybrid was successfully synthesized by a two-step microwave-assisted solvothermal reaction and heat treatment. The Li4Ti5O12 in the hybrid could deliver a discharge capacity of 154 mAhg(-1) of Li4Ti5O12 at 1 C-rate, 128 mAhg(-1) of Li4Ti5O12 at 50 C-rate and 101 mAhg(-1) of Li4Ti5O12 at 100 C-rate. It demonstrated promising potential as an anode material in a Li-ion battery with excellent rate capability and good cycling. (C) 2010 Elsevier B.V. All rights reserved.
