▎ 摘  要

NOVELTY - Preparation of continuous electrospinning super capacitor involves preparing graphene/carbon nanotube colloidal solution using graphene, carbon nanotubes, and solvents, spraying a graphene/carbon nanotube composite film anode on current collector using high-pressure electrostatic sprayer, preparing a solid electrolyte material, electrospinning the solid electrolyte film directly on the formed anode using a high-voltage electrospinning device, electrospraying the prepared colloidal solution on the electrolyte film to form a cathode, and attaching a layer of current collector. USE - Preparation of continuous electrospinning super capacitor. ADVANTAGE - The method produces flexible ultra-thin super capacitor with different capacities (0.2-0.4 F), by adjusting the thickness of anode and cathode from 10 mu m. The cathode and anode are three-dimensional structures comprising one-dimensional carbon nanotubes, and two-dimensional graphene, having excellent electroconductivity. The solid electrolyte has excellent contact properties with the anode and cathode. The ion conductivity of the electrolyte membrane can be improved by regulating the thickness of anode and cathode. DETAILED DESCRIPTION - Preparation of continuous electrospinning super capacitor involves preparing graphene/carbon nanotube colloidal solution by ultrasonically dispersing graphene, carbon nanotubes and solvents, spraying a graphene/carbon nanotube composite film anode on current collector using high-pressure electrostatic sprayer, preparing a solid electrolyte material, electrospinning the solid electrolyte film directly on the formed anode using a high-voltage electrospinning device, electrospraying the prepared graphene/carbon nanotube colloidal solution on the electrolyte film to form a cathode, and attaching a layer of current collector.
