Composite solid electrolyte for protection of active metal anodes
ActiveUS20070172739A1Eliminate through-porosityHigh metal ion conductivityCell electrodesPrimary cellsPorosityTectorial membrane
A composite solid electrolyte include a monolithic solid electrolyte base component that is a continuous matrix of an inorganic active metal ion conductor and a filler component used to eliminate through porosity in the solid electrolyte. In this way a solid electrolyte produced by any process that yields residual through porosity can be modified by the incorporation of a filler to form a substantially impervious composite solid electrolyte and eliminate through porosity in the base component. Methods of making the composites is also disclosed. The composites are generally useful in electrochemical cell structures such as battery cells and in particular protected active metal anodes, particularly lithium anodes, that are protected with a protective membrane architecture incorporating the composite solid electrolyte. The protective architecture prevents the active metal of the anode from deleterious reaction with the environment on the other (cathode) side of the architecture, which may include aqueous, air and organic liquid electrolytes and / or electrochemically active materials.

Alkali (or other active) metal battery and other electrochemical cells incorporating active metal anodes together with aqueous cathode / electrolyte systems. The battery cells have a highly ionically conductive protective membrane adjacent to the alkali metal anode that effectively isolates (de-couples) the alkali metal electrode from solvent, electrolyte processing and / or cathode environments, and at the same time allows ion transport in and out of these environments. Isolation of the anode from other components of a battery cell or other electrochemical cell in this way allows the use of virtually any solvent, electrolyte and / or cathode material in conjunction with the anode. Also, optimization of electrolytes or cathode-side solvent systems may be done without impacting anode stability or performance. In particular, Li / water, Li / air and Li / metal hydride cells, components, configurations and fabrication techniques are provided.

Electronic light emissive displays incorporating transparent and conductive zinc oxide thin film
InactiveUS6541908B1Discharge tube luminescnet screensElectroluminescent light sourcesDisplay deviceOxide cathode
The present invention provides co-doped zinc oxide to flat panel, light emissive display devices and vacuum microelectronic devices to improve their efficiency and lifetime. This material has a low growth temperature and is compatible with metal oxide semiconductor (MOS) processing technology. It is tranparent, chemically stable and has a low work function, which result in many advantages when being used as the cathode for the aforementioned devices. In one embodiment of the emissive display device, an organic light diode (OLED) display has a high work function metal anode, such as platinum (Pt), gold (Au) or nickel (Ni) and a low work function co-doped zinc oxide cathode. Because of the energy level alignment provided by these two materials, the potential energy barriers to injection of electrons from the cathode and holes from the anode into the organic emissive medium are minimized so the display device operates more efficiently.

The energy density of the entire cell may be improved while retaining high power density by use of an alkali metal transition metal polyanion compound as the cathode and a thin film metal or metalloid anode. The thin film anode may be initially unalloyed or partially unalloyed. During use, the thin film anode may be only partially unalloyed relative to the theoretical maximum. The high volumetric capacity of the metal anode makes it possible to use a dense or porous thin film anode in conjunction with a relatively thin particle-based cathode to thereby improve the energy density of the cell.
