Silver Oxide Batteries

Silver oxide batteries were invented by a team of researchers at the Union Carbide Corporation (now part of Energizer Holdings, Inc.) in the late 1950s.

They are a type of non-rechargeable button cell battery that utilizes silver oxide (Ag2O) as the cathode material. These batteries are commonly used in small electronic devices, watches, calculators, thermometers, glucose monitors, electronic scales, remote controls, shotgun-type condenser microphones, toys and other devices that draw a small charge and require a compact and long-lasting power source.

Silver oxide batteries are known for their high energy density, meaning they can store a significant amount of energy in relation to their size. They provide a stable voltage output throughout their discharge cycle and have a relatively long shelf life and very low discharge rate. This makes them suitable for applications requiring consistent power output over an extended period.
