Abstract
Films of active electrode material, such as films made from carbon and fibrillized polymer, are attached to a porous separator. Outer surfaces of the films (i.e., surfaces opposite those adjoining the separator) are then covered with current collectors. The 5 resulting stack is usable in fabrication of electrical energy storage devices. The stack can be shaped as needed, connected to terminals, and immersed in an electrolytic solution to provide a double layer capacitor.
