Abstract: A paste electrode comprising a current collector support, which is coated on at least one of its faces with a coating composed of a composition comprising an active material comprising an alloy of zinc with one or more chemical elements, and one or more binders. This electrode may be used as an anode of an electrochemical cell comprising alkaline electrolyte. The coating contains at most 0.5% by mass of mercury or mercury compound. The electrode in spite of this presents effective resistance to corrosion by the electrolyte.
