1. A method of manufacturing a plurality of elongated current collectors for alkaline electrochemical cells having an anode and a cathode comprising the steps of:
- a) electroplating a metal conductive wire with indium to form an indium plated wire, wherein the indium plating on said conductive wire has a thickness of between about 0.1 and 10 micron; and
b) drawing the indium plated wire formed in step a) to reduce the diameter thereof; and
c) inserting the drawn indium plated wire into said anode.

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.
