Do you know what impact lithium battery processing has on the environment?

In the process of processing lithium battery pole pieces into these links, there is no relatively large pollution with the domestic mainstream lithium iron phosphate system, even the ternary system. Of course, the ternary system may still have some pollution with lithium cobalt oxide. Yes, 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 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. Some reports generally say that batteries contain mercury, cadmium, lead, arsenic and other substances, which is inaccurate. In fact, cadmium, lead, arsenic and other substances do not need to be added during the processing of ordinary dry batteries used by the masses. Mercury in waste batteries does not pose a threat to the environment. Mercury has a low volatilization temperature and is a heavy metal with greater toxicity. The soil in many places also contains trace amounts of mercury. During the mining, refining, and production of mercury-containing products, if the containment measures are not complete, the mercury released into the air has a great impact on the health of operators. Although the battery contains mercury, its content is very small because it is an additive. Even for high-mercury batteries, the mercury content is generally within one thousandth of the weight of the battery. The amount of mercury used in the battery industry in my country throughout the year is roughly equivalent to the amount of mercury in the annual discharge of wastewater from a company that uses mercury-based PVC, or mercury-based gold smelting, or high-mercury lead-zinc mines. Due to the large battery consumption area, after mercury-containing waste batteries enter the domestic waste treatment system, the impact on the environment is much smaller than that caused by the mercury-containing wastewater discharged by the aforementioned chemical company. Moreover, the batteries use stainless steel or carbon steel as outer coverings. , Effectively prevent the leakage of mercury.
