The silver oxide button battery is an alkaline battery that uses an aqueous silver oxide solution for the anode, zinc for the cathode, and potassium hydroxide or sodium hydroxide for the electrolyte. Most silver oxide batteries are button-type primary batteries, but some secondary batteries can also be used.
The nominal voltage of the silver oxide button battery is 1.55v, which is higher than the 1.5v of alkaline batteries and 1.35v of mercury batteries, and the voltage curve for discharge time is flat, which means that the voltage can be maintained at approximately the same level for a long time.
Silver oxide button battery is a battery with silver oxide as the positive electrode, zinc as the negative electrode, and alkaline solution as the electrolyte.
Silver oxide button battery are characterized by high energy per unit volume and stable operating voltage. As a result, they are used as power sources for applications such as quartz watches, and in recent years, their use has expanded to medical devices and BLE devices.
