Abstract: Due to the sodium ion radius is 70% larger than lithium ion radius, the embedding for sodium ion in and out of the graphite electrode materials is more difficult, and the graphite material needs to be modified. Using the natural graphite as raw material, graphene oxide was prepared via the Hummers method. Using the tetra-n-butyl titanate as raw material on this basis, the precursor TiO₂/graphene oxide (TiO₂/GO) composite was prepared by sol-gel method, and the anatase type TiO₂/reduced graphene oxide (TiO₂/RGO) composite was obtained by heat treatment. The electrochemical test results show that when TiO₂ content is 15wt%, the TiO₂/RGO composites exhibit an initial discharge specific capacity of 74.08 mAh·g^-1 at current density of 20 mA·g^-1. And with the increase of the number of cycles, the discharge specific capacity gradually increases, and reaches 109.10 mAh·g^-1 after 50 cycles, and the charge-discharge efficiency is 65.59% after 50 cycles, which is also showing a trend of increasing. While the initial discharge specific capacity of pure reduction oxidation graphite is 41.43 mAh·g^-1, and reaches 20.47 mAh·g^-1 after 50 cycles.
