ABSTRACT:
A pre-form of an anode current collector for an alkaline electrochemical cell is plated at its edges with tin, zinc, or a combination of tin and zinc, to protect the anode current collector from chemically reacting with the anode paste, and forming hydrogen gas in the cell. The anode current collector, thus protected, is placed in an alkaline electrochemical cell with an anode paste preferably containing no mercury, without incurring deleterious swelling of the resulting cell.
