▎ 摘　　要

Ultra small TiO2 nanocrystals were well dispersed on reduced graphene oxide nanosheets through two-step hydrothermal treatments without any surfactants and high-temperature calcinations. Profiting from small TiO2 nanoparticles, high electronic conductivity and low carbon content, the nanocomposites presented excellent reversible capacity and high-rate performance for lithium storage.
