▎ 摘  要

NOVELTY - Preparing red phosphorus/graphene composite roll involves preparing red phosphorus particles, preparing graphene dispersion liquid, mixing the red phosphorus particles, graphene dispersion liquid and high boiling point organic solvent, freezing and solidifying, freezing and drying the solidified mixed solution to obtain the composite material. The mass ratio of the red phosphorus to the graphene is 0:1-5:1, the concentration of the graphene dispersion is 0.1-10mg/mL. The volume ratio of the high boiling point organic solvent and graphene dispersion is 0.01:100-5:100. USE - Method for preparing red phosphorus/graphene composite roll. ADVANTAGE - The method enables to prepare red phosphorus/graphene composite coil material has good conductivity, large specific surface area, which is an electrode material with high performance and has good industrial practicability in the lithium-ion battery.
