▎ 摘　　要

NOVELTY - Preparing fluorinated graphene comprises (i) providing graphite (S110), (ii) preparing (S120) graphene oxide using graphite by means of improved Hummers method, (iii) reducing (S130) graphene oxide to graphene using hydrazine hydrate, and (iv) reacting (S140) graphene with the fluorinating agent to obtain the fluorinated graphene. USE - The method is useful for preparing fluorinated graphene (claimed), which is useful: as an electrode material; and in lithium ion battery and super capacitor. ADVANTAGE - The method provides fluorinated graphene with good electric conductivity, good resistance and low thermal expansion coefficient, high strength and thermal conductivity. DESCRIPTION OF DRAWING(S) - The figure shows a flowchart of the method for preparing fluorinated graphene (Drawing includes non-English language text).
