What is the Silver Oxide Button Battery?

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.

What is the silver oxide button battery?

Silver oxide button battery belongs to a series of button batteries (button batteries can be divided into two categories: chemical button and physical button batteries, of which button batteries are divided into five categories: 

① Silver oxide button batteries

② Silver peroxide button batteries

③ Lithium button batteries

④ Alkaline manganese button batteries

⑤ Mercury button batteries), because of its compact size, and widely used in various types of micro electronic products.

The diameter of silver oxide button cell is usually φ11.6mm, φ9.5mm, φ7.9mm, φ6.8mm, and the thickness (height) of silver oxide button cell is usually 5.4mm, 4.2mm, 3.6mm, 2.6mm, 2.1mm. The common models of silver oxide button cell include AG1, AG2, AG3, AG10, AG13, SR626, etc. (Among them, AG is the JAPAN Japanese standard, SR is the international standard).

What is the selection method for silver oxide button battery?

Silver oxide button battery series are suitable for high working voltage and smooth discharge, especially for low current and long time continuous use of electrical appliances. The prefix and suffix represent the chemical composition of the battery. The same product appears in multiple groups of digital models, which are called different in different countries and regions, but are the same product. The same model, different brands can be common, the battery is generally used in low power consumption instrumentation, the normal use time of about 2 years or more (except for high power consumption machines).

How does the silver oxide button battery work?

The silver oxide button battery, like the mercury battery, has an extremely smooth discharge voltage curve. The silver oxide button battery has approximately the same ampere-per-hour capacity as a mercury battery, but it operates at 1.5v (1.6v open circuit). The silver oxide button battery is an important power source for hearing aids and electric meters. The positive electrode (cathode) is a depolarized oxide of silver oxide and manganese dioxide, with the composition of the mixture varying with the application; the negative electrode is zinc. The silver oxide battery used in hearing aids (which requires low drain current and long life) has a strong alkaline potassium hydroxide electrolyte to enhance its energy density, while the silver oxide battery used in electronic meters (very low drain current and long life) has a more stable sodium hydroxide (50-diumhydroxide) electrolyte.

Overall, the important role of silver oxide button battery in our daily lives is perceived by more and more people. Guangzhou Dolphin Information Technology Co., Ltd. strives to offer high quality silver oxide button battery at reasonable prices, efficient production times and the most professional customer service.
