NOVELTY - An iron(III)oxide-doped graphene anode material preparing method involves stirring an iron source in water magnetically to obtain an iron salt solution. The iron salt solution is added with ammonia water under magnetic stirring condition for adjusting pH value to obtain a colloid solution. The colloid solution is stirred with a strong cationic polyelectrolyte solution magnetically to obtain a mixed solution. The mixed solution is dried and grinded, followed by subjecting the grinded powder to high temperature graphitizing heat treatment and oxidation process to obtain the finished product. USE - Method for preparing an iron(III)oxide-doped graphene anode material. ADVANTAGE - The method enables preparing the iron(III)oxide-doped graphene anode material with better structural stability, better electrical conductivity and better effect of increasing effective contact area of lithium ions to electrode material.
