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.
