What are the hazards of waste lithium-ion batteries?

If the discarded lithium-ion battery is not handled properly, it will contain lithium hexafluoride, carbonate organic compounds and heavy metals such as cobalt and copper, which 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 precious resources with high recycling value. Therefore, the scientific and effective disposal of waste lithium-ion batteries not only has significant environmental benefits, but also has good economic benefits. 、

When the waste lithium pool is discarded as garbage and enters nature, the heavy metals in it cannot be biodegraded, causing serious pollution to the environment. According to statistics, a 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 waste batteries is mainly concentrated on a small amount of heavy metals, such as lead, mercury and cadmium. These toxic substances enter the human body through various channels, and long-term savings are difficult to eliminate, damaging the nervous system, hematopoietic function and bones, and even causing cancer.

1. Mercury (Hg) has obvious neurotoxicity, in addition, it also has adverse effects on endocrine system and immune system, which can cause rapid pulse, muscle tremor and oral and digestive system diseases;

2. Cadmium (Cd) enters the human body through various channels, and long-term savings are difficult to eliminate, which damages the nervous system, hematopoietic function and bones, and even causes 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.
