What are the hazards of used lithium batteries?

What are the hazards of used lithium batteries? Lithium batteries are not harmful to the human body and the environment during normal use. However, if discarded lithium batteries are improperly handled, they will cause harm to the environment, and then through environmental use to the surrounding organisms and human body. This is important because chemical substances such as lithium hexafluorophosphate and polypropylene diethylene (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 treatment of waste lithium batteries, it must first be pre-treated, including discharge, dismantling, crushing, and sorting; the plastic and iron shells after dismantling can be recycled; and then the electrode materials are 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 decomposition and hydrolysis products, such as DME, methanol, formic acid, etc., are all toxic and hazardous substances. Send it to a qualified place for unified treatment, don't throw it away at will. Lithium storage 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 excessively high temperature will cause dangers such as battery explosion and fire, which directly threaten people's lives and property.
