Silver oxide battery is a small-sized primary battery mainly used for wrist watches, using zinc as the negative electrode (cathode), silver oxide as the positive electrode (anode) plus an alkaline electrolyte . Thanks to its high energy density and superb stable discharge characteristics, silver oxide batteries are being used in a broad range of applications, from quarts watches to portable devices such as electric clinical thermometers and portable games.
To cope with a sharply-growing demands for high-quality, compact and slim batteries, Sony has realized the ultimate in compact batteries and high performance, ensuring high reliability by taking advantage of the state-of-the-art micro battery design & production technologies that Sony has developed over the past years. Sony also has a wide product line-up available to cater for the diversifying market needs.

| Silver oxide (Ag2O) is used for the active cathode material, and Specially processed fine zinc-alloy powder is used for the active anode material. Potassium hydroxide is used for high drain type silver oxide battery as a electrolyte, and sodium hydroxide is used for low drain type. |
|
| Battery discharge reactions are follows |
 |
| With open circuit voltage of approx. 1.55V, the battery voltage is extremely stable and impedance remains low during discharge. |
|
 |
 |
60°C 20-days and 60°C 40-days storage conditions are equivalent to 1 years and 2 years, respectively, at room temperature.
Excellent long-term reliability
After storage, decrease in discharge time is minima1. |
