A silver-containing alkaline electrochemical cell and methods for
producing the cell, wherein the cell includes a negative electrode, a
positive electrode, a separator disposed between the electrodes, and an
alkaline electrolyte, wherein the positive electrode is formed as a
multi-layer composite including a silver-containing oxide layer and a
barrier layer, initially free of silver-containing material, disposed
between the silver-containing oxide layer and the separator for
substantially reducing migration of silver ions to the separator and
negative electrode.
