NOVELTY - Method for preparing laminated fluorinated graphene for positive electrode of lithium battery involves subjecting mixture of N-layer graphene and stabilizer to shear emulsification, homogenizing, freeze-drying and annealing to obtain laminated graphene, and performing high-temperature fluorination of the laminated graphene assisted by alloy balls to obtain the product, where the stabilizer is polyvinyl alcohol, the mass ratio of graphene and polyvinyl alcohol is (1-2):1, and the ratio of double covalent bond on the surface of the laminated fluorinated graphene is 10-20%. USE - The method is useful for preparing laminated fluorinated graphene for positive electrode of lithium battery. ADVANTAGE - The method uses fluorinated graphene which has a laminated sheet-layer stacking structure to provide more reaction sites, and retains 10-20% of C=C bonds on its surface to improve the electrical conductivity of the material.
