What Are the Practical Uses of Silver Oxide Button Battery?

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.

What are the practical uses of silver oxide button battery?

The silver oxide button battery is specifically designed to meet a wide variety of applications with different power requirements.

1. Watches and Calculators - Silver oxide watch batteries using a sodium hydroxide (NaOH) electrolyte system are primarily designed for long periods of low drain continuous use, typically up to five years. This is common in analog watch applications.

Silver oxide watch batteries using the potassium hydroxide (KOH) electrolyte system are primarily designed for continuous low drain with periodic high drain pulses required for a period of about one to two years. This is typical of applications such as LCD watches with backlighting, analog watches with alarms, and calculators.

2. Hearing Aids - silver oxide button battery Continuous discharge rate produces greater volumetric energy density. Hearing aid and electronic batteries use a potassium hydroxide electrolyte

combined with a separator system designed to match the desired application.

3. Photo - silver oxide button battery is used to provide constant voltage or periodic high drain pulses with or without low drain background current.

What are the dimensions of silver oxide button battery?

Silver oxide button battery has long service life and high capacity, and is very widely used and has the largest amount of applications. This type of battery consists 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 through the chemical interaction of zinc and silver oxide. The thickness (height) of silver oxide button cell has 5.4mm, 4.2mm, 3.6mm, 2.6mm, 2.1mm five specifications, its diameter has 11.6mm, 9.5mm, 7.9mm, 6.8mm four specifications. In the selection should be based on the size of its location, choose one of them. Its common models are AG1, AG2, AG3, AG1O, AG13, SR626, etc. Its model AG is the Japanese standard and SR is the international standard model.

How is the silver oxide button battery recycled?

Silver oxide button battery is consumed by corrosion because the zinc in the negative electrode can react chemically with the components in the electrolyte, which not only reduces the usable capacity of the battery, but also generates hydrogen gas, causing the internal pressure of the battery to expand. To inhibit this effect, a small amount of mercury is usually applied to the zinc surface, but this also results in mercury pollution of the environment from the discarded cells. The battery clips of silver oxide batteries can also be recycled, therefore, silver oxide batteries should be practically recycled to avoid polluting the environment.
