Abstract
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.
