  • Electric cell with zinc coil anode and method of making it
    Patent number: 4007054
    Abstract: A zinc wire coil is wound as a helix on a conducting support such as a copper or brass wire or rod, and the unit amalgamated in a mercuric salt solution to form a rigid anode element; in a cell such anode maintains substantially uniform spacing between anode and cathode to maintain substantially uniform current flow distribution.Using a multi-strand cable, or multiple layers of zinc wires for the helix permits predetermined percentage ratio of porosity to volume of anode.
