Abstract:
1. An electrochemical cell, comprising: a first and a second electrode; a separator disposed between the first electrode and the second electrode; an aqueous alkaline electrolyte; and a cell housing comprising a first electrode housing and a second electrode housing and an electrically insulating seal member disposed between the first electrode housing and second electrode housing, the cell housing containing the first electrode, second electrode, separator and electrolyte, wherein the first electrode housing is in contact with the first electrode and has an interior surface and an exterior surface and comprises a substrate plated with an alloy layer, wherein the alloy layer comprises copper, tin and zinc, and wherein the substrate is a copper-stainless steel-copper triclad substrate; the interior surface and the exterior surface of the first electrode housing substrate are post-plated with the plated alloy layer; and a surface portion of the plated alloy layer has a lower copper content than a portion of the plated alloy layer contacting the substrate.
