1,226,144. Anode. LEESONA CORP. 29 Jan., 1969 [4 April, 1968], No. 4810/69. Heading H1B. An anode for an electrochemical cell par ticularly a metal/air or metal/oxygen cell, comprises a porous metal body 2 wrapped in a first layer 4 of hydrophilic gas impermeable material, such as a cellulosic membrane like unglycerinated desulphured fibrous cellulose, which is preferably cut away at 4À1 at the top on one side of the anode, having a plurality of slits or holes therein, and a second layer 5, preferably in bag form which is hydrophilic dimensionally stable and heat sealable such as a fibrous synthetic material of, for example, copolymers of vinyl chloride and acrylonitrile, polyamide polymers, copolymers of polyvinyl alcohol and polyvinyl chloride, and polyacrylate esters. The anode shown in Fig. 1 may also include a metal screen 1 which supports metal body 2. Silver current collector tabs 3 are attached to the metal screen, and are placed in contact with a bus-bar 6 which is in contact with terminal plugs 7. A handle 8 is attached to the bus-bar. A non-conductive plastic anode top 9 is encapsulated over the bus-bar around the base of terminal 7. The metal body may be made by compressing at an elevated temperature metal particles such as Pb, Zn, Fe, Cd, Al or Mg, which may include a plastics binder. Alternatively, metal oxides can be used which are reduced electrolytically or chemically and followed by compression. |
