NOVELTY - Preparing bismuth pentoxide/reduced graphene oxide composite anode material involves mixing the graphene oxide nanosheet with water, stirring, and ultrasonically dispersing to obtain a dispersion of graphene oxide nanometer, dissolving and dispersing antimony pentachloride in water, stirring to obtain a suspension of antimony pentachloride, and adding an organic solvent to the antimony pentachloride suspension. The dispersion of the graphene oxide nanoparticle is mixed with the white solution, stirred until the dispersion is uniform to obtain mixed solution, and placed obtained mixed solution in a high-pressure reaction vessel for hydrothermal reaction, after hydrothermal reaction is completed. The precipitate generated by the hydrothermal reaction is collected, and the obtained precipitate is washed and dried to obtain solid powder. The solid powder is subjected to heat treatment under an argon atmosphere to obtain ruthenium pentoxide/reduced graphene oxide composite anode material. USE - Method for preparing bismuth pentoxide/reduced graphene oxide composite anode material. ADVANTAGE - The method enables to prepare bismuth pentoxide/reduced graphene oxide composite anode material that has convenient operation, controllable reaction condition, excellent cycle and rate performance.
