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.

An electrochemical cell is provided with first (10) and second (11) electrodes and a solid polymer electrolyte (15) disposed therebetween. The solid polymer electrolyte is preferably fabricated by providing a linear powdered polymeric precursor material which is thereafter heated to temperatures sufficient to drive off moisture and in the presence of an electrolyte active species. The electrolyte active species is preferably an acidic electrolyte active species which has the effect of protonating the powdered polymeric precursor material. Electrochemical cells fabricated using these devices demonstrate performance characteristics far better than those available in the prior art.

摘要:
A hybrid electrode for a high power, high energy, electrical storage device contains both a high-energy electrode material (42) and a high-rate electrode material (44). The two materials are deposited on a current collector (40), and the electrode is used to make an energy storage device that exhibits both the high-rate capability of a capacitor and the high energy capability of a battery. The two materials can be co-deposited on the current collector in a variety of ways, either in superimposed layers, adjacent layers, intermixed with each other or one material coating the other to form a mixture that is then deposited on the current collector.

摘要:
A structure for an optical switch includes a reflective layer formed over a high quality epitaxial layer of piezoelectric compound semiconductor materials grown over a monocrystalline substrate, such as a silicon wafer. The piezoelectric layer can be activated to alter the path of light incident on the reflective layer. A compliant substrate is provided for growing the monocrystalline compound semiconductor layer. An accommodating buffer layer comprises a layer of monocrystalline oxide spaced apart from a silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying piezoelectric monocrystalline material layer.
