Abstract

A spinel Li4Ti5O12 nanoplatelet/reduced graphite oxide nano-hybrid was successfully synthesized by a two-step microwave-assisted solvothermal reaction and heat treatment. The Li 4Ti5O12 in the hybrid could deliver a discharge capacity of 154 mAhg- 1 of Li4Ti5O 12 at 1 C-rate, 128 mAhg-1 of Li4Ti 5O12 at 50 C-rate and 101 mAhg-1 of Li 4Ti5O12 at 100 C-rate. It demonstrated promising potential as an anode material in a Li-ion battery with excellent rate capability and good cycling.
