Abstract
An electrochemical cell is provided with a first and second electrode assemblies (10) (11), and an electrolyte (15) disposed therebetween. The electrodes may either be of the same or different materials and may be fabricated from ruthenium, iridium, cobalt, tungsten, vanadium, iron, molybdenum, nickel, silver, zinc, and combinations thereof. The electrode assemblies are fabricated by depositing a layer (16) of a conductive ink adhesive on a surface of a current collecting substrate (12). Thereafter, a layer of powdered active material (18) is impregnated onto the surface of the conductive ink layer.
