PCT No. PCT/US94/05571 Sec. 371 Date Nov. 16, 1995 Sec. 102(e) Date Nov. 16, 1995 PCT Filed May 18, 1994 PCT Pub. No. WO94/28590 PCT Pub. Date Dec. 8, 1994A 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.
