Abstract: A method of electroconductive fastening of electroconductive materials in electrochemical devices, where a sheet of metal or a sheet of electrically conductive fibers is to have a second sheet joined thereto which can be of solid sheet metal, and where at least one tape with an adhesive layer thereon is placed on top of one of the sheets, with the adhesive layer facing the sheets, and the assembly is subjected to pressure, and the adhesive layer is activated, causing the sheets to fasten together in electroconductive contact, and wherein a second tape with an adhesive layer facing the sheets may be applied from the other side prior to pressure application.
Abstract: A solid state polymeric electrolyte which is formed by complexing an alkaline metal triflate salt and polyethylene oxide with an ester an ether or a pyrrolidinone and an ether, or two ethers of different boiling points as co-solvents to form a solid or semi-solid state electrolyte.
Abstract: Apparatus for drying and/or treating powdered, granular, or flaked material in combination with a containment room or glove box under controlled atmospheric conditions, which may have an oven in the room with a chamber with a vessel therein to carry material, the chamber having a door to seal it off and vacuum creation and gas supplying features directly therefor, the vessel which carries material for drying and/or treating is supported on a frame with provisions for rotation by motor equipment, with heater elements around the outside of the chamber to provide heat if required, and vanes inside the vessel to fluidize the material upon rotation and the application to the vessel of vacuum, heat, and/or gas for drying and/or treating the material as required.
Abstract: A solid state polymer electrolyte composite which is formed by coating an inert electrically insulating ribbon or sheet of expanded or perforated plastic film with a liquid, ion-conductive polymer, and curing the polymer to form a solid state or semi-solid state electrolyte composite.
Abstract: Battery packaging construction for multiple cell alkali metal batteries wherein a plurality of flat or cubic battery cells, which have leads extending therefrom, are individually packaged by using layers of heat sealed or adhesively sealed plastic tape. The cells after assembly are stacked and the leads are electrically connected in series or parallel to terminals, and are secured by a band of tape, or glued together, and then enclosed in a plastic coated metal foil bag, heat sealed and adhesive sealed for moisture-proofing. The bag is placed in a hard box which is then closed to form the completed battery with the terminals extending therefrom. The hard box may optionally be provided with a liner of vibration and impact shock absorbing material.
Abstract: A solid state polymer electrolyte composite which is formed by impregnating a fibrous open mesh, electrically non-conductive net, with a liquid, ion-conductive polymer, and curing the polymer to form a solid state or semi-solid state electrolyte composite.
Abstract: An improved alloy or composite electrode of lithium, magnesium and other materials in which magnesium is in the range of 5 to 50% of the total weight of the composite. The lithium and magnesium metal can be heated until they melt, and combine, and are cast into an ingot which is then formed into the desired shape as an electrode and placed into an electrochemical device or formed as an anode and placed into a battery. Other methods of combination can be used as desired to obtain the electrode.
Abstract: A solid state polymer electrolyte composite which is formed by impregnating an electrically non-conductive fibrous net with a liquid, ion-conductive polymer, and curing the polymer to form a solid state or semi-solid state electrolyte composite.
Abstract: Protection of anodes in alkaline metal or alkaline earth metal batteries is provided by covering the exposed side of the anode with a plastic film or metal foil that is coated with an adhesive composition, which plastic film and adhesive may be anhydrous.
Abstract: Lightweight electroconductive wire which includes a strip of lithium metal with copper connectors at each end, and encapsulated within a layer of moisture proof aluminum foil, which has an anhydrous glue coating with an outer encapsulating layer of insulating plastic tape that has a coating of adhesive retaining it on the foil. The copper contacts extend outside the layer of tape and are plated with metal that is non reactive with lithium at contact with the lithium.
Abstract: Battery packaging construction for batteries of flat configuration which includes a first layer of heat sealable plastic coated metal foil. A battery on top of the first layer with a second layer of heat sealable plastic coated metal foil on top of and facing the battery which plastic layers are heat sealed under vacuum. An optional frame may surround the battery on top of the second layer, which frame is adhesively secured to the second layer, filler material is placed around the frame and the foil and cured by ultra violet light or electron beam, a third layer is adhesively secured to the frame and a label layer is placed on the third layer.Terminals of flat metal foil extend from the battery out between the first and second foil layers over and under the base and are secured to the bottom layer. An elongated base plate may optionally be provided which has the layer of adhesively secured foil on the bottom, and the first layer of adhesively secured foil on the top surface of the base.

Abstract: This invention is directed to a lightweight solderless connector for use as an internal cell connector in an alkaline metal or alkaline earth metal battery, wherein the connector includes a core of alkaline metal or alkaline earth metal such as lithium metal in flat foil form, which has been encapsulated inside a layer of insulating plastic film such as polyester or polypropylene, with an adhesive coating therebetween, which is preferably anhydrous adhesive.
Abstract: A solid state polymer electrolyte which is formed by mixing an ultraviolet light or electronbeam curable epoxide based polymer with an electrolyte and curing the mixture whereby the polymer cross links and forms a solid state or semi-solid state electrolyte.
Abstract: A method and apparatus for coating a substrate with alkaline or alkaline earth metals is disclosed. The apparatus includes a reservoir to contain a melt of the metal, means for breaking the melt into fine droplets, and means for advancing a substrate having a surface to be coated along a path past the means for breaking the melt into fine droplets which contact the surface and provide a coating of the desired thickness. The apparatus coats the substrate in a pure inert gas environment. Use of the above apparatus provides a method for coating an alkaline or an alkaline earth metal onto a substrate to be realized.
Abstract: The contact area of the anode of lithium batteries with the electrolyte is substantially increased by deposition of minute lithium particles on the anode base layer to form an irregular layer in contact with the electrolyte which reduces the manufacturing cost and increases the contact area which increases the ion exchange between the lithium particles and the electrolyte.
Abstract: Electrodes for a solid-state battery at least one of which comprises a layer of ionic and electronic conductive polymer spheres. Each polymer sphere consists of an active electrode material core encapsulated in an ionically and electronically conductive polymeric material.
Abstract: A photographic printer apparatus is provided, with quick change self-threading magazines of photographic material which enables use of different widths and types of photographic material at the input of the printer apparatus. A cutter station is positioned within the printer console adjacent the magazine input, where roll material is pre-cut to the desired size of the photographic print to be made before being exposed. Transport systems are provided in the console for vacuum guidance and positioning of the photographic material while it is being cut and for accurately positioning the photographic material opposite a first exposure station for exposure, and for transporting the piece of photographic material to a second exposure station or for storage and subsequent processing or to a continuously running processor adapted to develop, and wash and dry the previously exposed photographic material.
