Recovery Of Button Batteries
- Jan 19, 2018 -

Alkaline batteries using zinc electrodes, silver oxide batteries, and zinc-air batteries, the anode zinc and electrolyte components can produce chemical reactions, and thus will be consumed by corrosion, which will not only impair the usable capacity of the battery, may and will produce hydrogen, resulting in airtight battery internal pressure increase and expansion.

In order to inhibit such a role, usually in the zinc surface covered with a small amount of mercury, but also caused by the waste battery on the environment caused by mercury pollution, although there is no Mercury button battery listed, but because of technical or patent reasons, mercury-free button battery is not popular. button battery is not in the general dry cell mercury-free ban, still allow the existence of a small amount of mercury, must be firmly in accordance with the instructions of the Environmental Protection Unit recycling.
