Zinc-silver batteries use metal zinc as negative electrode, silver oxide (AgO, Ag 2 O or a mixture of them) as positive electrode, 22 and KOH or NaOH aqueous solution as electrolyte. The divalent oxide is relatively stable at ambient temperatures but is inclined to degrade to the monovalent state with increasing temperature and time.
A silver zinc battery is a secondary cell that utilizes silver (I,III) oxide and zinc. Silver zinc cells share most of the characteristics of the silver-oxide battery, and in addition, is able to deliver one of the highest specific energies of all presently known electrochemical power sources.
The positive silver electrode is made from sintered silver powder or silver oxide converted into metallic silver. Its cycle life depends on the depth of discharge and temperature, and it can exceed 5000 cycles under favorable conditions. The overall electrochemical cell reaction is
A silver oxide battery uses silver (I) oxide as the positive electrode (cathode), zinc as the negative electrode (anode), plus an alkaline electrolyte, usually sodium hydroxide (NaOH) or potassium hydroxide (KOH). The silver is reduced at the cathode from Ag (I) to Ag, and the zinc is oxidized from Zn to Zn (II).
A great advance has been made for the application of the zinc silver battery to the power supply for the equipment of wearable and implantable electronic device, especially in the field of aerospace.
The possibility of charging the silver electrode beyond the monovalent oxide Ag20 to a formally bivalent oxide(27-29) is quite alluring at first sight. On one side the thermodynamically calculated cell voltage is increased from 1.594 to 1.856 V, and on the other the Ah capacity of the positive electrode is doubled.

OverviewConstructionHistorySpecificationsMercury contentSee alsoExternal links
In order to reduce the cost of manufacture, most commercially available silver oxide cells take the form of button cells with relatively low silver content. These button cells generally follow the same compact design. The bottom portion of the cell is the cathode, which consists of a graphite infused silver oxide. A plastic membrane separates this from an anode of powdered zinc dissolved in an alkaline electrolyte. An insulating gasket keeps the two contacts apart, facilitating the discharge …
