Harm and preventive measures of small button type battery

Most of the micro-button batteries used are mercury-free, so there is no need to worry about their impact on the environment. Domestic and foreign battery cell products sold in the market must be labeled with mercury content (mercury content in battery products labeling methods, domestic environmental battery manufacturers have different labels, such as "low mercury", "no mercury" or "mercury 0", "mercury 0" and other ways). Consumers who buy batteries need only check their mercury content to know if they are environmentally friendly.

Environmental impact of micro-button battery

Most of the micro-button batteries used are mercury-free, so there is no need to worry about their impact on the environment.

Domestic and foreign battery cell products sold in the market must be labeled with mercury content (the mercury content in battery products is labeled differently by domestic eco-friendly battery manufacturers, such as "low mercury", "no mercury" or "mercury 0", "mercury 0" and other ways). Consumers who buy batteries need only check their mercury content to know if they are environmentally friendly.

Small button type battery safety risk

Toddlers between the ages of 1 and 3 are prone to inhalation and ingestion of micro-button batteries. Injuries caused by accidental ingestion of button batteries are mainly caused by the electrolytes in the batteries. Acidic or alkaline electrolytes can cause chemical reactions in the body that can cause internal organs to burn, corrode, corrode and even perforate.

Seriously corroded button batteries enter the human esophagus, the metal layer on the surface of the battery may dissolve, leakage will cause its internal organs to be burned, corroded, corroded and even perforated, thus seriously endangering life.

Small button battery precaution

Micro-button battery recovery: In alkaline batteries, silver oxide batteries and zinc air batteries using zinc electrodes, the zinc in the negative electrode and the components in the electrolyte will undergo chemical reactions, which will be corroded and consumed, not only reducing the availability of the battery may produce hydrogen gas, which leads to an increase in the internal pressure and expansion of the sealed battery. To counteract this effect, zinc is usually coated with a small amount of mercury, but this can also contribute to environmental mercury pollution through the disposal of micro-button batteries. Although mercury-free button batteries are already on the market, they are not widely available for technical or patent reasons.

Micro-button batteries fall outside the mercury-free ban on conventional dry batteries, still allow small amounts of mercury and must be recycled as directed by the Environmental Protection Agency.
