NOVELTY - A plate type anatase titanium oxide/graphene composite material preparing method involves mixing water, organic amine and anhydrous alcohol uniformly to obtain mixed liquid-. The liquid-I is mixed with isobutyl titanate to form uniform milk white suspension, which is allowed to stand to obtain white precipitate. Water is mixed with graphene oxide and anhydrous alcohol to obtain mixed liquid-II. The white precipitate is processed ultrasonically by adding the mixed liquid-II for 2-3 hours, and by adding ethylene diamine for 1-2 hours to obtain mixed liquid-III. The mixed liquid-III is transferred into a reaction kettle to carry out closed isothermal crystallization reaction under autogenous pressure to obtain reacted product. The reacted product is centrifuged, followed by washing a solid product to obtain finished product. USE - Method for preparing plate type anatase titanium oxide/graphene composite material that is utilized in negative electrode active material of lithium ion battery. ADVANTAGE - The method enables preparing the composite material with hierarchical structure, improved electrochemical performance and yield, in simple manner.
