▎ 摘　　要

NOVELTY - Preparing modified lithium titanate/redox graphene composite cathode material comprises (i) adding carbon-coated titanium dioxide into solution containing lithium source for reaction to obtain lithium titanate material, (ii) mixing lithium titanate material, reducing agent, and graphene oxide uniformly in solvent, reacting and calcining at high temperature to obtain lithium titanate/redox graphene composite anode material, (iii) subjecting lithium titanate/graphene composite cathode material to gas fluorination treatment to obtain modified lithium titanate/redox graphene composite cathode material. USE - The method is useful for preparing modified lithium titanate/redox graphene composite cathode material. ADVANTAGE - The cathode material: has fast reaction speed, high degree of fluorination, excellent performance without using high concentrations of acids and bases, and shortens preparation time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for modified lithium titanate/redox graphene composite cathode material obtained by above method.
