The invention discloses an organic sulfur compound anode material, and an aluminum ion battery and an anode piece for the aluminum ion battery. The compound anode material is prepared according to the method comprising the following steps: dissolving a high-molecular polymer into a carbonic ester solvent, thereby obtaining a polymer solution; mixing organic sulfur powder with the polymer solution; filtering and taking filter residue; washing and drying, thereby obtaining the organic sulfur compound anode material. The mass ratio of high-molecular polymer to organic sulfur powder is (10-50):(5-20); the high-molecular polymer is any one or combination of polypropylene carbonate, polydiethylsiloxane, polymethyl acrylate and polymethyl methacrylate; the high-molecular polymer is covered on the organic sulfur surface, so that the stability of organic sulfur of the core is increased and the product yield of the pole piece processing is increased; the material is taken as the anode material for preparing the aluminum ion battery and the coating layer of the high-molecular polymer is dissolved in the organic electrolyte, so that the characteristic of high specific capacity of the organic sulfur is fully exerted.
