What kinds of pollution will occur when processing lithium batteries?

Are lithium batteries really green? Lithium battery: Green and environmentally friendly, no matter it is processed, used or discarded, it does not contain or present any toxic and harmful heavy metal elements and substances such as lead, mercury, and cadmium. Others, such as storage batteries and fuel power batteries, generally contain heavy metal elements, such as mercury, lead, cadmium, etc.; these are heavy metal elements, which are very toxic and pollute water and soil. Lithium batteries are widely used in the electric vehicle industry, especially the emergence of lithium iron phosphate batteries, which has promoted the development and application of the lithium battery industry. From the perspective of the development of new energy vehicles, lithium batteries are more environmentally friendly, and the development of automotive fuels is accompanied by the development of energy. In the oil era, automobiles used gasoline and diesel as power fuels, which not only caused air pollution in cities, but also caused fuel prices to rise with the shortage of oil supply. Gas vehicles and biofuel vehicles appeared as alternative fuels. Now the domestic recycling lithium battery industry has just started, and the corresponding recycling rate is only 2%, which is really difficult to meet environmental protection standards. It is generally believed that lithium iron phosphate batteries are more suitable for cascading use, and ternary lithium batteries are suitable for direct recycling. However, whether it is cascaded use or recycling, the power lithium-ion battery recycling in the early stage of development still has an immature business model, lack of sufficiently effective waste battery collection channels, battery disassembly/disassembly mismatch, and remaining life prediction difficult problem. What pollution does lithium battery processing cause? Lithium battery production line processing and whether it will cause (gas, water and soil) pollution during the process. At the current stage of lithium battery processing, lithium batteries will not be polluted by (toxic heavy metals). But regarding the environment, it is definitely harmful. Lithium battery pole piece production process: In these processes, the domestic mainstream lithium iron phosphate system, or even the ternary system, does not have relatively large pollution. Of course, the ternary system may still be somewhat similar to lithium cobalt oxide. For example, cobalt, manganese, and nickel are all heavy metals, but they are relatively environmentally friendly. Among them, lithium iron phosphate batteries are 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. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
