High drain rate, primary alkaline cell having a divalent silver oxide/monovalent silver oxide depolarizer blend coated with a layer of silver
Реферат: ABSTRACT OF THE DISCLOSURE A high drain rate, primary alkaline cell comprising a negative electrode, a divalent silver oxide (AgO)/monovalent silver oxide (Ag2O) depo-larizer blend, a separator between said negative electrode and depolarizer blend, and an alkaline electrolyte consisting essentially of potassium hydro-xide. The surface of the depolarizer blend adjacent to the separator is coated with a layer of silver. The reduced surface layer of the depolarizer provides improved stability of the depolarizer blend in the alkaline electrolyte, and it provides the cell with a single voltage plateau during discharge. The cell is characterized by a maximum open circuit voltage of about 1.75 volts. The surface of the depolarizer blend can be reduced to form the silver layer ei-ther prior to being placed in the cell container or after the blend is consoli-dated in the container. The amount of divalent silver oxide present in the depolarizer blend is critical, and the blend may contain up to about 70% by weight of divalent silver oxide and still achieve a single voltage plateau during discharge. The cell has a high drain rate capability whereby is can be pulsed, said cell being capable of providing a flash amperage greater than an average of 0.20 amperes per square centimeter of cell cross-sectional area.
