What are the hazards of used lithium batteries?

If the end-of-life lithium-ion batteries are not handled properly, the lithium hexafluorate, organic carbonate and heavy metals such as cobalt and copper will definitely pose a potential pollution threat to the environment. On the other hand, cobalt, lithium, copper and plastic in waste lithium-ion batteries are valuable resources with high recovery value. Therefore, the scientific and effective treatment and disposal of waste lithium-ion batteries not only has significant environmental benefits, but also has good economic benefits.

When used lithium batteries are discarded as garbage and enter the nature, the heavy metals in them are not biodegradable and cause serious pollution to the environment. According to statistics, a used battery can make 1 square meter of soil permanently lose its value, and a button battery can pollute 600,000 liters of water.

The harm of used batteries is importantly focused on the small amount of heavy metals contained in them, such as lead, mercury, cadmium, etc.. These toxic substances enter the human body through various ways, and are difficult to be eliminated after long-term accumulation, damaging the nervous system, hematopoietic function and bones, and can even cause cancer.

1. mercury (Hg) has obvious neurotoxicity, in addition to the endocrine system, the immune system and other adverse effects, can cause accelerated pulse, muscle tremors, oral and digestive system lesions.

2. cadmium (Cd) elements enter the body through various ways, long-term accumulation is difficult to eliminate, damage to the nervous system, hematopoietic function and bone, and can even cause cancer.

3. Lead (Pb) can cause neurasthenia, numbness of hands and feet, indigestion, abdominal cramps, blood poisoning and other lesions; manganese can harm the nervous system.
