Manufacturing method of lithium-ion capacitor

Abstract

Disclosed is a manufacturing method of a lithium-ion capacitor, comprising a positive electrode production step of mixing a lithium-rich material, activated carbon, a conductive additive and a aqueous adhesive to form a slurry by using water as a solvent, and then applying the slurry to a carbon-coated aluminum foil to form a positive electrode sheet; a negative electrode production step of mixing a negative electrode material, a conductive additive and a aqueous adhesive to form a slurry by using water as a solvent, and then applying the slurry to a copper foil to form a negative electrode sheet; and an assemble step of assembling the positive electrode sheet, the negative electrode sheet, an electrolyte and a separator into a capacitor without pre-lithiation.
