zinc-silver oxide cell

The zinc-silver oxide battery is an alkaline system that uses a silver oxide cathode and a powdered zinc anode. It is known for its ability to handle significant current load pulses and maintain a stable 1.5-volt operating voltage. Due to these characteristics, it is commonly found in small electronic devices like watches, cameras, and hearing aids, often in a button cell form. Despite its higher cost, its robust current-carrying capacity has led to its use in military applications, such as torpedo batteries. Miniature versions can utilize either divalent or monovalent silver oxide, with the former typically offering a greater capacity. This type of battery was developed in the 1930s and 1940s, offering high energy density for its size and weight.12
