<p>. GALVANIC ELEMENT The zinc corrosion which prevails in galvanic cells having negative zinc electrodes, and which is accompanied by H2 gas evolution, can be effectively prevented by the use of an anode zinc which is either free of mercury or at most contains 1% by weight of mercury, and in which only the electrode take-off conductor is amalgamated. It generally takes the form of a nail, wire or the housing lid of button cells and can consist, among other things, of copper, brass, bronze, copper plated iron, alloy steel, or a Cu-Fe-Ni trimetal. Zinc plating may be performed prior to amalgamation of the take-off conductor.</p> |
