How does the dry battery have no mercury?


Mercury is known as “mercury”, is a substance for liquid at room temperature, which prevents oxidation of cathode metal zinc in the battery, which improves the battery life.


Therefore, it is hard to make preservatives with a certain amount of mercury in the previously used zinc. However, the combination of mercury and mercury has neurotoxicity, and there is a negative impact on endocrine systems, immune systems, etc., which will cause people with tenth tooth, step instability, paralysis, and finally lead to whole body spasm, mental disorders.


With the advancement of technology, the battery began to gradually implement low and mercury-free, and mercury substitute surfactant FORAFAC fluorinated polymers, in preventing the corrosion of zinc, has achieved good results.

For a long time, when my country’s production of dry batteries, a compound of toxic substance-mercury or mercury is added. my country’s alkaline dry batteries have a mercury content of 1% to 5%, and the neutral dry battery is 0.025%, and the mercury used in the production of dry batteries nationwide is more than tens of tons.
