▎ 摘　　要

NOVELTY - Preparing flower-shaped fluorinated graphene of lithium battery anode, comprises shearing and emulsifying mixed solution of N-layer graphene and polyvinyl alcohol, homogenizing, atomizing and drying, and annealing to obtain flower-shaped graphene, where the N is a positive integer with 3 less than or equal to N less than or equal to 10, the N-layer graphene size is 1-50 microns, the mass ratio of the N-layer graphene and polyvinyl alcohol is 1:1-2, carrying out high temperature fluorination to the flower-shaped graphene stirring blade, and obtaining flower-shaped fluorinated graphene, where the ratio of carbon-carbon bond of the surface of the flower-shaped fluorinated graphene is 10-15%. USE - The method is useful for preparing flower-shaped fluorinated graphene of lithium battery anode. ADVANTAGE - The graphene provides larger reaction area and active sites because the fluorinated graphene has flower-shaped layer mesh structure, and improves the conductivity of the material.
