NOVELTY - Preparation of poly(3,4-ethylenedioxythiophene)-doped beta -akaganeite/reduced graphene oxide array lithium ion battery anode material comprises dissolving graphene oxide in 25-50 mL deionized water and ultrasonically dispersing; dropwise adding analytically pure soluble iron salt and 0.01-0.05 mL 3,4-ethylenedioxythiophene while stirring, dissolving, and ultrasonically dispersing with 0.05-0.5 mol/L iron salt and graphene oxide to obtain suspension; hydrothermal reacting at 50-150 degrees C and naturally cooling to room temperature; washing with water and alcohol and dispersing in water; and vacuum freeze-drying at - 20 degrees C to - 50 degrees C and 10-60 Pa. USE - Method for preparing poly(3,4-ethylenedioxythiophene)-doped beta -akaganeite/reduced graphene oxide array lithium ion battery anode material. ADVANTAGE - The lithium ion battery anode material has good reduction-oxidation property, good conductivity, large specific surface area, and improved dispersion of iron oxide, self-assembly morphology, and improved electrochemical performance.
