Rutile TiO2 nanobundles on reduced graphene oxides as anode materials for Li ion batteries.

A simple and steerable method was adopted to synthesize well-distributed rutile TiO2 nanobundles on reduced graphene oxides through two-step hydrothermal methods. The rutile TiO2-RGO composites were used as the anode materials in lithium ion batteries for investigation, which had an original morphology and a reversible capacity of 300 mA h g(-1) at 0.6 C and 200 mA h g(-1) at 1.2 C after 500 cycles.
