Abstract
The voltage level of an electrochemical cell having a divalent silver oxide (AgO) cathode is reduced to and maintained at the monovalent silver oxide (Ag.sub.2 O) level by an attenuated divalent silver oxide layer between the divalent silver oxide cathode and the cathode current collector.
Claims10
An electrochemical cell comprising an anode, a cathode, a cathode current collector, and an electrolyte wherein said cathode comprises divalent silver oxide, a portion of said divalent silver oxide is attenuated in a direction parallel to the adjacent surfaces of said cathode and said cathode current collector, and the portion of said divalent silver oxide which is attenuated is positioned adjacent the surface of said cathode current collector whereby an increase in internal cell resistance is introduced, and wherein the amount of divalent silver oxide in the attenuated layer is 20 to 50 percent by volume and the balance is a non-conductive, non-reactive material.
