Silver oxide button battery has the advantages of smooth discharge, high energy to weight ratio, etc. It is generally used as a button battery, or used in some specific applications that require higher requirements and can afford the high cost, such as some torpedoes or submarines.
Silver Oxide Button Battery is composed of silver oxide as the positive electrode, zinc metal powder as the negative electrode, and potassium hydroxide or sodium hydroxide as the electrolyte. Electricity is generated by the chemical interaction between zinc and silver oxide.
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.
Silver oxide button battery is a silver powder with a few percent of graphite powder (to increase the electrical conductivity), mixed with a small amount of binder, extruded with a die to form the required pill-shaped positive electrode, negative zinc powder with a small amount of mercury oxide, extruded with a die to form a pill-shaped negative electrode, positive and negative electrodes with a diaphragm and barrier layer between. Silver oxide is silver gray.
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.
