Silver Oxide Batteries

Silver oxide primary batteries are widely used in electronic equipment that requires small, compact power sources. The high volumetric energy density of silver oxide button cells, and their ability to deliver energy at relatively high current drains, makes them ideal for miniature devices where space is limited.

Silver oxide batteries are also noted for their extremely stable discharge voltage, good shelf life, and ability to operate over a wide temperature range. These unique characteristics make these batteries ideally suited for applications such as low-power LCD watch and calculator displays, quartz analog watches, and some camera applications.Read more

In a silver oxide battery, silver oxide is used as the cathode and zinc as the anode. An alkaline electrolyte, usually sodium hydroxide or potassium hydroxide, is included in the chemistry, as well. Chemical reactions inside the battery reduce the silver content from Ag(I) to AG, and oxidize the zinc from Zn to Zn(II). Spent silver oxide batteries are sometimes recycled for their precious metals (silver), but the quantity of silver present in most batteries of this type is so small that this is generally impractical.

In comparison to other batteries, silver oxide batteries have flatter discharge curves than standard alkalines, as well as higher open circuit potential than mercury batteries. Prior to the development of lithium-ion technology, silver oxide batteries had the highest energy density of any battery chemistry. Still, silver oxide batteries provide up to 40 percent greater run time than lithium-ion batteries. Silver oxides’ water-based chemistry also prevents thermal runaway and flammability, potential problems that lithium-ions have been known to experience.
