▎ 摘  要

NOVELTY - A fluorinated graphene modified lithium titanate material comprises fluorinated graphene and 55-98 wt.%, preferably 70-94 wt.% lithium titanate. USE - The fluorinated graphene modified lithium titanate material is used as lithium battery cathode electrode active material (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the fluorinated graphene modified lithium titanate material comprising mixing lithium acetate, organic alcohol, acetic acid, deionized water, and fluorinated graphene into uniform liquid; adding 1.0-20 times, preferably 4.0-10 times organic titanium compound, stirring for 0.5-10 hours, preferably 1.5-6 hours, filtering, centrifuging, or evaporating to get mesophase, putting mesophase under inert atmosphere gas, calcining at 300-1000 degrees C for 1-24 hours, preferably 400-850 degrees C for 3-12 hours, and cooling, where modified lithium titanate material comprises 0.2-1.8 pts. wt. lithium acetate, 40-90 pts. wt. organic alcohol, 1.0-3.0 pts. wt. acetic acid, 0.1-6 pts. wt. deionized water, and 0.1-5 pts. wt. fluorinated graphene.
