What are the hazards of processing lithium-ion batteries?

Li-ion battery production line processing, and will the process cause (gas, water and soil) pollution? At the current stage of lithium-ion battery processing, lithium-ion batteries (Li-ion) will not have (toxic heavy metals) pollution of. 1. Speaking from the battery itself, of course, this concept is relative, and lead-acid, nickel-chromium batteries, its pollution is very small, there is no heavy metal pollution. But regarding the environment, it is definitely harmful (chemicals are not poisonous). Electrode materials and electrolytes and solvents may be contaminated: once again, these are extremely low pollution compared with traditional batteries. 2. Let's talk about the pollution that may occur in the process of processing the battery. The pole piece production process: In these processes, the domestic mainstream lithium iron phosphate ion system, or even the ternary system, does not have relatively large pollution. Of course, the ternary system may still have a certain difference with the lithium cobalt oxide ion. For example, cobalt, manganese, and nickel are all heavy metals, but they are relatively environmentally friendly. Among them, lithium iron phosphate is the most environmentally friendly. The remaining part, in addition to the pollution of the materials mentioned above, the solvent in the injection is mainly cyclic/chain carbonate or carboxylic acid ester. The most important solute is lithium ion salt, lithium hexafluorophosphate, and the most important additives are film-forming additives, flame retardant additives, conductive additives, and additives to improve low-temperature discharge. The pollution in the whole process is okay. Of course, chemical agents, if you don't pay attention to their control, will definitely pollute the environment. As for the final packaging and formation, the pollution is even smaller. 3. Let's talk about the recycling part about lithium cobalt oxide ions and the ternary system. Of course, recycling is still necessary, after all, it contains heavy metals. However, lithium iron phosphate is basically harmless except for the internal electrolyte and so on. Compared with other batteries, there are no toxic and harmful metal elements and substances such as lead, mercury, and cadmium, so the pollution is relatively small.
