Abstract: An alkali metal anode is compressed on a metal current collector and is adhered thereto by means of a metal which spontaneously alloys with the alkali metal at room temperature.

Abstract: An electrical device stabilized for long life operation comprising a cathode electrode including a porous layer of electrically conductive metal containing material, an electrolyte including an inorganic acid contacting the cathode electrode, and a cathode depolarizer including copper salt. A method of depolarizing an electrical device comprising the steps of forming a cathode electrode of layers of materials including a porous layer of electrically conductive metal containing material, contacting the cathode electrode with an electrolyte including an inorganic acid and a depolarizer including copper salt, reducing the copper salt to copper, and depositing copper on the cathode electrode as copper metal.

Abstract: A solid electrolyte additive for high energy density solid state cells, comprising aluminum oxide treated with a polar covalently bonded alkali metal.

Abstract: A high conductivity stable clovoborate electrolyte salt is used in alkali and alkaline earth metal non-aqueous secondary cells to prevent dendritic formation of the plated alkali or alkaline earth metal.

Abstract: An enclosure for an electrochemical device, especially useful for electrochemical cells having an internal pressure above ambient, wherein the enclosure is formed in accordance with techniques based upon aerosol container filling procedures.

Abstract: A solid state electrochemical cell containing a cathode comprising a compound which is solid at ambient temperatures and which contains a halogen atom, a chalcogen atom and an atom of a third element, with the chalcogen and halogen not in a redical grouping.

Abstract: A process for treating monovalent silver oxide (Ag.sub.2 O) alone or in combination with other materials to increase its compressibility, increase its ability to absorb electrolyte, and decrease its carbon dioxide absorption rate by the step of heating the silver oxide or silver oxide mixture to temperatures of from about 150.degree. C to about 300.degree. C for a period of time from about 1 hour to about 5 hours.

Abstract: A sealing grommet in a cylindrical electrochemical cell designed for long term use, the grommet having an extended area which is compressed between a separator having structural integrity and a cell top.

Abstract: A solid state cell separator interposed between electrode and electrolyte thereby allowing use of highly reactive materials in the electrode.

Abstract: A gas-depolarizable galvanic cell is provided having restricted gas access to the cathode. The cell is generally a metal-air cell, and may particularly be a button cell suitable for use in electronic watches, hearing aids and the like. The restricted gas access to the cathode comes either by way of a very small aperture in the cell container, or in an additional barrier layer placed within the cell. The cross-sectional area of the gas passageway is less than the projected area of the gas passageway through the thickness of the container or additional barrier layer; and may be formed by piercing or punching but more particularly by exposing the container or the material of the additional barrier layer to a laser beam.

Abstract: An hermetic vent utilizing a metal-to-glass-to-metal seal between a metallic disc and a metallic container.

Abstract: Apparatus for the construction of cathodes from pasty materials and expended metal substrates. A continuous roll of conductive metallic mesh is fed past a coating device and coated on one side. Simultaneously the coated metallic mesh is supported by an absorbent felt belt which is pressed against the mesh and removes excess liquids. After being coated on one side the mesh is turned over and further coated in a similar manner.

Abstract: A gas-depolarizable galvanic cell in which restricted gas and water vapor access to the gas-depolarizable cathode is provided by interposing a gas and moisture impermeable barrier in the gas communication path and carefully controlling the size of holes or openings in the barrier so as to restrict the gas flow rate past the barrier.

Abstract: An electrochemical device including electrically conductive elements with a polymeric fluorocarbon coating electrically insulating the electrically conductive elements of the device.A method of making the electrochemical device including the steps of providing an electrically insulating, fluorocarbon material contiguous to one of the electrically conductive elements. The polymer is treated, in situ, to form a substantially continuously adherent coating of polymeric fluorocarbon material over the electrically conductive element.

Abstract: A high energy density cell or battery capable of undergoing flexular stress with little effect on its discharge properties either during and after subjection to stress.
