Silver Oxide Batteries

Silver oxide batteries

Silver oxide batteries are small-sized primary batteries with high capacity and stable discharge characteristics. It is suitable for quartz watches, medical devices and precision instruments. All models are 100% made in Japan, and environmentally friendly 0% mercury.

Murata Icon X Feature

  • High energy density : High energy density has been achieved owing to the Murata's original high-precision material-mixing technology. The use of antioxidant, high performance separators also contributes to improved storage characteristics.
  • Excellent stable discharge characteristics : Constant voltage output is available during the discharging.
  • Excellent leakage resistance : Murata-unique sealing structure, coupled with special sealing- material treatment, has helped accomplish the excellent leakage resistance.

Murata Icon X Principle of Silver Oxide Battery

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 as an electrolyte.
Battery discharge reactions are follows
Principle of Silver Oxide Battery

With open circuit voltage of approx. 1.55V, the battery voltage is extremely stable and impedance remains low during discharge.
