Double Hydrothermal Synthesis of Graphene Supported TiO2(b) Nanosheets as Anode Materials for Lithium Ion Batteries

摘要

The synthesis of graphene supported TiO_2(b)nanosheets by a double hydrothermal method for lithium storage was reported.The titanate nanosheets synthesized by the first hydrothermal progress and the graphene oxide obtained by the oxidation of graphite were hydrothermally treated together to fabricate the TiO_2(b)/graphene composite.The electrochemical measurements illustrate that the graphene supporter obviously improves the cyclic performance of TiO_2(b),which can be attributed to the better dispersion and the decrease of resistance for the TiO_2(b)nanosheets in the composite.
