▎ 摘  要

NOVELTY - The method involves mixing the active material, conductive agent, and dry powder of dispersant through a material mixing mechanism (2) on the surface of a preparation table (1). One or more of carbon-based composite materials, graphite materials, and amorphous carbon, the conductive agent is one or more of carbon black, acetylene carbon black, carbon nanotubes, and graphene, and the dry powder of the dispersant is CMC. The binder is added and a material stirring mechanism (4) is wetted and stirred. The binder is polyvinylidene fluoride, polytetrafluoroethylene, butadiene One or more of benzene rubber, sodium carboxymethyl cellulose, polyvinylpyrrolidone, polyvinylidene fluoride-hexafluoropropylene, PVP-polyvinyl butyral, natural cellulose, PVDF-HFP/PVP. The prepared slurry is uniformly coated on the surface of the metal current collector through a coating mechanism (6). The metal current collector is aluminum foil or copper foil. The electrodes are rolled by rolling equipment. USE - Dry electrode preparation method for supercapacitors. ADVANTAGE - The method is configured to enable reversing a knob handle, the discharging plate and the metal current collector to be coated back to an initial position so as to conveniently finish blanking of the slurry, thus effectively improving convenience of subsequent coating metal current collector. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a dry electrode preparation device for supercapacitors. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the electrode preparation device.
