Button-type silver oxide batteries are characterized by high-energy per unit volume and stable operating voltage. As a result, they are used as a power source for applications such as quartz watches, and in recent years their use has expanded to medical devices and BLE devices.
Maxell is the first company in Japan to successfully market button-type silver oxide batteries and has many years of experience and know-how. Also, in consideration of the environment, all products are designed to use zero mercury. For more information, please contact Maxell.
The button-type silver oxide battery uses silver oxide (Ag2O) as its positive active material and zinc (Zn) as its negative active material. Potassium hydroxide (KOH) (W-type) or sodium hydroxide (NaOH) (SW-type) is used as an electrolyte.
