The invention relates to a reduced graphene oxide modified antimony trisulfide battery anode material. The battery anode material is prepared by following steps: (1) adding Sb2S3 powder into anhydrousethanol, then dispersing the solution into a graphene oxide solution, and stirring the mixed solution until the mixed solution becomes uniform and stable to obtain a precursor solution; (2) transferring the precursor solution obtained in the step (1) to a hydrothermal reactor, heating the hydrothermal reactor to carry out reactions, and cooling the reactor to the room temperature to obtain suspension; and (3) filtering the suspension obtained in the step (2), washing, and drying to obtain the target product. Compared with the prior art, an Sb2S3 nano rod is prepared by a hydrothermal method,the preparation method is simple, the process is easy to control, the raw materials are easily available, and the cost is low. The prepared reduced graphene oxide modified Sb2S3 nano composite structure has an excellent electrochemical sodium storage performance and is a good sodium ion battery anode material.
