NOVELTY - Polyoxometalate-based polydopamine battery anode material is coated with reduced graphene oxide. USE - Polyoxometalate-based polydopamine battery anode material. ADVANTAGE - The polyoxometalate-based polydopamine battery anode material can be uniformly fixed on the carbon carrier graphene oxide plate, which improves electrical conductivity and workability of the anode material, and has extremely high mechanical strength and chemical stability. The preparation method has reduced steps, mild reaction conditions, low cost and high yield. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing polyoxometalate-based polydopamine battery anode material, which involves: (A) adding dopamine powder and graphene oxide solution to phosphorus-vanadium-molybdenum aqueous solution under stirring for 1 hour; (B) transferring the resulting mixture to an autoclave lined with Teflon; (C) heat treating at 160 degrees C for 16 hours; and (D) cooling at room temperature to obtain polyoxometalate-based polydopamine battery anode material as a black powder.
