  • Method of preparing current collectors for electrochemical cells
    Patent number: 5622612
    Abstract: A process is recited for plating elongated current collectors with indium. The current collectors have particular utility in alkaline electrochemical cells, particularly zinc/manganese dioxide alkaline cells containing "zero-added" mercury. The process of the invention involves electroplating conductive wire with indium and then drawing the plated wire to a lesser diameter. The drawn plated wire may then be cut to the desired lengths, typically in the shape of a nail, for use as current collectors within the alkaline cell.
