Abstract:
A free-standing flow-through capacitor, comprising:a first electrode, the first electrode comprises an active material and an electronically conductive foil, wherein the active material and the electronically conductive foil are integrated into a first flexible monolithic sheet; a first divider disposed on the first electrode; a second electrode disposed on the first divider, the second electrode comprises the active material and the electrically conductive foil, wherein the active material and the electronically conductive foil are integrated into a second flexible monolithic sheet; and a second divider disposed on the second electrode, wherein the first electrode, the first divider, the second electrode and the second divider are wound concentrically into a hollow-center roll with a center opening, wherein said first and second dividers are sheets with pattern containing horizontal strips and vertical porous supports, wherein the horizontal strips are thicker than the vertical supports, so that said divider provides a gap between the electrodes in the roll assembled.
