A group around LI Yuliang at CAS QIBEBT has introduced fluorine atoms into the structure of graphene. By fluorine substitution, the pores of the graphene alkene were enlarged, but the basic framework of the graphene and the conjugate system in the two-dimensional planar structure were retained. The new material had excellent conductivity and carrier transport properties; the fluorocarbon bond has excellent lithium storage capacity and shows good compatibility towards the electrolyte. Interfac impedance was reduced, thereby improving cycle stability.
