Analysis of the hazards of used lithium batteries

Lithium batteries are not harmful to the human body and the environment during normal use. However, if the discarded lithium batteries are improperly solved, they will cause harm to the environment, and then use the environment to the surrounding organisms and human body. This is important because chemical substances such as lithium hexafluorophosphate and polypropylene (alcohol) contained in lithium batteries can cause organic pollution to the environment. In addition, heavy metal elements such as cobalt contained in it will also cause harm to the environment. For example, in the solution to the waste lithium battery, it must first be pre-solved, including discharge, dismantling, crushing, and sorting; the plastic and iron casing after dismantling can be recycled; and then the electrode material is subjected to alkaline leaching and acid leaching. After leaching, various procedures followed by extraction. The electrolyte and conversion products of waste lithium batteries, such as LiPF6, LiAsF6, LiCF3S03, HF, P201, etc., solvents and their analysis and hydrolysis products, such as DME, methanol, formic acid, etc., are all toxic and hazardous substances. Send it to a qualified place for a unified solution, don't throw it away at will. Lithium batteries contain a variety of toxic substances, which are highly corrosive and polluting. In addition, the waste lithium battery electrolyte contains extremely toxic, flammable, explosive, and corrosive electrolytes and organic solvents. If discarded or leaked arbitrarily, it will cause pollution and damage to the atmosphere, water, and soil. In addition, electrolyte leakage and high temperature will cause battery explosion and fire hazards, which directly threaten people's lives and property. In addition, a series of pollutants, such as electrolyte analysis, plastic film pyrolysis, cracking dust, waste residue, etc., will appear in the process of rupture sorting and high-temperature pyrolysis of waste lithium batteries. The atmosphere and water bodies cause serious pollution and are severely corrosive to the equipment. At the same time, the various acid-base extractants, extractants, and active additives to be added during the process not only increase the cost of the recovery process, but also cause waste of resources and energy. Consumption increased, and a large amount of waste water, waste gas, waste residue, waste additives, etc. added secondary pollution. The hazards of waste batteries The hazards of waste batteries are concentrated 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, long-term accumulation is difficult to eliminate, damage the nervous system, hematopoietic function and bones, and even cause cancer. 1. Mercury (Hg) has distinct neurotoxicity, and also has adverse effects on the endocrine system and immune system, which can cause pulse speed, muscle tremor, oral and digestive system diseases; 2. Cadmium (Cd) enters through various channels In the human body, long-term accumulation is difficult to eliminate, damages the nervous system, hematopoietic function and bones, and can even cause cancer; 3. Lead (Pb) can cause neurasthenia, numbness of hands and feet, indigestion, abdominal cramps, blood poisoning and other diseases; manganese Will harm the nervous system.
