NOVELTY - Fluorinated graphene modified niobium pentoxide material comprises fluorinated graphene and 55-98 %mass, preferably 70-94 %mass niobium pentoxide. USE - The fluorinated graphene modified niobium pentoxide material is useful as electrode active material in negative electrode of lithium battery (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the material involving (a) dispersing organic alcohol, fluorinated graphene and aqueous ammonia, and mixing into a uniform liquid comprising 40-90 parts mass organic alcohol, 0.1-5 parts mass fluorinated graphene, and 0.5-10 parts mass ammonia (based on 40 %mass ammonia), (b) adding 1-20 times, preferably 4-10 times the liquid to niobium halide, and stirring for 0.5-10 hours, preferably 1.5-6 hours, and (c) filtering, centrifuging or evaporating the liquid to obtain an intermediate liquid phase, calcining the intermediate liquid phase under an inert gas at 300-1000 degrees C, preferably 400-850 degrees C for 1-24 hours, preferably 3-12 hours, and cooling to obtain a powder material.
