▎ 摘　　要

NOVELTY - A modified lithium titanate composite material is prepared by mixing graphene oxide solution, lithium titanate, water and nitrogen source, heating, reacting to obtain nitrogen-doped graphene modified lithium titanate composite material, and dipping amine source mixed with solvent. The nitrogen source is pyridine nitrogen, pyrrole nitrogen and graphitized nitrogen. The amine source is formed with covalent bond action. USE - Method for preparing modified lithium titanate composite material used as electrode material (claimed). ADVANTAGE - The method is simple for lithium titanate amine functionalized graphene coating.
