1,109,524. Batteries. WESTINGHOUSE ELECTRIC CORPORATION. 5 July, 1965 [11 Aug., 1964], No. 28349/65. Heading H1B. A secondary battery electrode comprises a plate formed from a compact body of intermingled metal fibres which extend generally parallel in one linear direction, active material distributed throughout the body of fibres, and an electrolyte permeable wrapper enclosing the plate. The intermingled fibres may be formed from steel, nickel, " Monel," (Registered Trade Mark), or other metal wool, and the wool may be plated with Cu, Ni, Zn, Ag or Cd. The wool used is obtained in the form of generally parallel fibres. Active materials mentioned are silver oxide, nickel hydroxide, indium hydroxide, iron hydroxide, zinc hydroxide and cadmium hydroxide. Minor amounts of copper, nickel, cobalt or palladium hydroxides may be added to silver oxide preferably by co-precipitation to reduce the particle size of the silver oxide. The steel wool grid for the silver electrode is plated with copper and then silver. The steel wool of a cadmium electrode is plated with cadmium and the active mass preferably comprises cadmium hydroxide and carbon black. For a nickel electrode nickel-plated steel wool was used. The wrapper may be cellulose, nylon, or polypropylene. The electrode is manufactured by preparing a slurry of active material, with or without additive, coating the metal wool grid, applying a vacuum to the grid so that the active material penetrates it, drying, and finally compressing and cutting to size. Reference has been directed by the Comptroller to Specification 844,937. |
