At present, the scrapping and recycling of waste lithium batteries are directly carried out by lithium battery manufacturers. For the scrapping and recycling of new energy lithium batteries, which are gradually increasing, it is also an extension of the economic chain for recycling. Our current recycling and application technology of waste lithium batteries tends to be mature, intelligent and advanced.
The recycling methods of waste lithium batteries are as follows:
1. Recycling and transportation: The recycling and transportation process is the beginning of the entire recycling chain of waste lithium batteries. This step is also a relatively simple step in the entire process. Do a good job of prevention and transport the waste lithium batteries, or hand them over to professional transportation industries for transportation.
2. Discharge and disassembly: There are many concepts proposed for the discharge part of the machine in the current industry, but when applied to production applications, wet technology is more desirable, and the others are short-circuit discharge: The most important method of physical discharge is to discharge with the help of an external load, which is to connect the battery to an external resistor so that the remaining power is consumed in the process of heat release, but this method is suitable for discharging a small amount of batteries
3. Disassembly and screening: Disassembly and screening are a step in the formal processing after discharge. Disassembly is to use the characteristics and principles of the machine. There is a process distinction in the disassembly configuration of the shell of different waste batteries and lithium batteries. The process is the same in the configuration of the screening and processing equipment for the positive and negative electrode materials and active materials after disassembly. The process and technical equipment of this step are currently an implementable and favorable method in the application of many lithium battery companies by Resek. The finished products after screening are generally: copper and aluminum metals, positive and negative electrode active materials, and diaphragm materials.
4. Collection and extraction: The collection facilities are configured in the production line of waste lithium battery recycling and utilization technology equipment. Extraction refers to the extraction of precious metals from the positive and negative active materials obtained after sorting. Generally, the extracted cobalt, lithium, manganese and other valuable metals have multiple applications. Waste lithium battery recycling and processing machine: For the recycling and processing machine of waste lithium batteries, our company has made a technical innovation process, which has been updated and applied. Friends from inside and outside the industry are welcome to visit our factory for inspection and trial operation.
