A stable TiO-graphene nanocomposite anode with high rate capability for lithium-ion batteries.

A rapid microwave hydrothermal process is adopted for the synthesis of titanium dioxide and reduced graphene oxide nanocomposites as high-performance anode materials for Li-ion batteries. With the assistance of hydrazine hydrate as a reducing agent, graphene oxide was reduced while TiO nanoparticles were grown on the nanosheets to obtain the nanocomposite material. The morphology of the nanocomposite obtained consisted of TiO particles with a size of ∼100 nm, uniformly distributed on the reduced graphene oxide nanosheets.
