▎ 摘  要

NOVELTY - Composite anode material comprises 0.1-10 wt.% manganese dioxide, 10-25 wt.% conductive polymer and fluorinated graphene (balance amount). USE - The composite anode material is useful for lithium perfluorocarbon battery (claimed). ADVANTAGE - The composite anode material: improves battery's specific energy and rate performance, high-current discharge performance and capacity utilization rate and electronic conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing composite anode material comprising (i) adding monodisperse fluorinated graphene solution for preparing fluorinated graphene to anhydrous alcohol solution, then stirring monodisperse fluorinated graphene solution using ultrasonic oscillation, (ii) moving monodisperse fluorinated graphene solution to high shear shearing homogenizer for shear dispersion, (iii) adding manganese dioxide powder and the conductive polymer into the shear dispersed monodisperse fluorinated graphene solution and adding into zirconium oxide ball milling tank through milling mechanical mixing, (iv) removing out ball milling mixed slurry and adding into the oven for drying, and (v) crushing the dried mixture and sieving to obtain fluorinated graphene/manganese dioxide/conductive polymer composite anode material.
