Abstract

See full text

A process for producing a supercapacitor cell, comprising: (a) Continuously feeding a conductive porous layer to a cathode material impregnation zone, wherein the conductive porous layer contains interconnected electron-conducting pathways and at least 70% by volume of pores; (b) Impregnating a wet cathode active material mixture (containing a cathode active material and an optional conductive additive mixed with a liquid electrolyte) into pores of this porous layer to form a cathode electrode; (c) Preparing an anode electrode in a similar manner; and (d) Stacking an anode electrode, a porous separator, and a cathode electrode to form the supercapacitor, wherein the anode electrode and/or the cathode electrode has a thickness no less than 100 μm; and/or wherein the anode or cathode active material constitutes an electrode active material loading no less than 7 mg/cm2 in the anode or the cathode.
