A device for producing an electro-motive force is disclosed. The device includes a cover for creating a liquid seal, an electrolyte contained within the cover for creating an ionic transfer path (medium), and an etched tri-metal board (substrate). The etched tri-metal board has a first conductive layer, a second conductive layer and a third conductive layer. The first, second and third conductive layers are selectively etched to form a cathode and an anode. The cover is sealed against the substrate and filled with an electrolyte to form an electrical device, such as a battery. |
