What are the hazards of used lithium-ion batteries
If the scrapped lithium-ion battery is improperly disposed of, the lithium hexafluorate, carbonate organic compounds, and heavy metals such as cobalt and copper will inevitably pose a potential pollution threat to the environment. On the other hand, cobalt, lithium, copper and plastics in waste lithium-ion batteries are valuable resources with extremely high recycling value. Therefore, scientific and effective treatment and disposal of waste lithium-ion batteries not only has significant environmental benefits, but also has good economic benefits. ,
When waste lithium ponds are discarded as garbage and enter the nature, the heavy metals in them cannot be biodegraded, causing serious pollution to the environment. According to statistics, a single waste battery can permanently lose the value of 1 square meter of soil, and a button battery can pollute 600,000 liters of water.
The harm of used batteries is mainly concentrated on the small amount of heavy metals contained in them, such as lead, mercury, cadmium and so on. These toxic substances enter the human body through various ways, and it is difficult to eliminate long-term accumulation, damage the nervous system, hematopoietic function and bones, and even cause cancer.
1. Mercury (Hg) has obvious neurotoxicity, and also has adverse effects on the endocrine system, immune system, etc., which will cause rapid pulse, muscle tremors, oral and digestive system lesions;
2. Cadmium (Cd) element enters the human body through various ways, long-term accumulation is difficult to eliminate, damages the nervous system, hematopoietic function and bones, and even can cause cancer;
3. Lead (Pb) can cause neurasthenia, numbness of hands and feet, indigestion, abdominal cramps, blood poisoning and other diseases; manganese can harm the nervous system.
