▎ 摘　　要

NOVELTY - Preparation of self-assembled microsphere-based anode material involves dissolving graphene oxide in ethylene oxide, ultrasonically treating, obtaining a suspension (A), adding a pure soluble iron salt and a surfactant to deionized water, adding suspension (A), adding a mixed solution comprising ethylene glycol and water, treating using microwave, mixing resultant with urea or melamine in mass ratio of 1:1-5, sealing and pyrolyzing. The concentration of iron salt is 0.05-0.5 mol/L. The concentration of the surfactant is 0.05-0.5 g/L. The concentration of graphene oxide is 0.5-2.5 mg/ml. USE - Preparation of self-assembled microsphere-based anode material (claimed). ADVANTAGE - The method provides self-assembled microsphere-based anode material having excellent electroconductivity. The battery provided with the self-assembled microsphere-based anode material has improved cycle stability.
