Abstract
An electrochemical capacitor cell (140) is provided with first and second electrodes (146) (148), and a solid polymer electrolyte (154) is 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, hafnium, nickel, silver, zinc, and combinations thereof. The solid polymer electrolyte is in intimate contact with both electrodes, and is made from a polymeric support structure having dispersed therein an electrolyte active species. Also a method of fabricating a biopolar electrochemical charge storage device by assembling at least the first and second bipolar subassemblies together with the second layer of electrode active material for the first bipolar subassembly in direct contact with the first layer of electrode active material for the second bipolar subassembly without a current collector disposed therebetween.
