The present invention provides a process for fabricating an n-cell supercapacitor stack, including a step of providing at least n+1 identical, or substantially identical, electrically inert conductive sheets having a defined perimeter, n identical, or substantially identical, ion-permeable insulating sheets having a defined perimeter, n identical, or substantially identical, first electrodes having a defined perimeter, n identical, or substantially identical, second electrodes having a defined perimeter, and at least n matching dielectric frames having an outer perimeter, which is larger than the perimeter of the conductive sheet and the perimeter of the insulating sheet; a step of assembling the supercapacitor stack, a step of disposing an additional conductive sheet on top of the nth second electrode; and a step of attaching adjacent units onto one another, such that at least one of the frames within each unit is attached to at least one of the frames within each respective unit adjacent thereto. Further provided is a sealing system for use in fabricating a supercapacitor stack, which includes matching current collectors and separators having externally extending framing structures.

Processes and systems for supercapacitor stack fabrication

The present invention is of an electrode comprising an electrode substrate, wherein the electrode substrate has an electrode side and a back side; a conductive material layer disposed on the back side of the electrode substrate; and an insoluble electroactive material disposed on the electrode side of the electrode substrate. The electrode substrate can be a conductive substrate or a non-conductive substrate. In an embodiment wherein the substrate is a non-conductive substrate, the electrode can include vias which extend from the electrode substrate backside to the electrode side of the substrate. In some embodiments, the electroactive material is zinc and the conductive material is silver. The present invention provides an electrode with improved current distribution and high capacity, which can provide higher current and/or higher voltage. In addition, the present invention provides a dermal patch, which includes a higher powered, high capacity electrode with uniform current distribution. Still further the present invention provides methods of making the electrode and of attaching the electrode to a power source.
