How to properly recycle and dispose of scrapped power lithium batteries?
How to deal with the scrapped power lithium battery? If it is not handled properly, it will bring serious secondary pollution. For example, lithium iron phosphate battery, once the electrolyte leaks, it will lead to toxic corrosiveness. The inflow into the natural environment causes great pollution. The commonly used ternary lithium battery also has heavy metals such as manganese, cobalt, and nickel, which will cause serious pollution to the water source and soil. So what are the reasonable recycling methods for these batteries? How to use them?
At present, there are two methods for the recycling of lithium batteries, one is cascade utilization, and the other is recycling. Cascade utilization is to detect classification disassembly and reorganization. Reuse the whole package, module, and battery cell in good condition in other scenarios where the battery performance requirements are not so high.
The other is physical and mechanical crushing, decomposition and refining. Waste lithium batteries undergo a series of processes such as shredding, crushing, positive and negative powder screening, and waste gas treatment to achieve recycling and cost reduction of battery materials.
And the whole process from the battery crushing to the final refining is closed. A sealed conveyor belt conveys broken battery waste. The treatment process is operated under negative pressure. The equipment is equipped with an alkaline water spray system, a pulse dust removal system, and an air purification system. The whole set is processed to ensure a good working environment.
Environmentally friendly recovery of valuable metal substances in discarded lithium batteries, especially for the recovery of copper foil, aluminum foil and black powder in the positive and negative plates of waste lithium batteries, also has a good effect.
No chemical components are added to the whole process, no chemical treatment process is used, and it is completely environmentally friendly. With the cooperation of equipment, the production line is easy to operate, the recovered materials are uniform, and there is no secondary pollution to the environment.
