Waste lithium battery recycling process and methods

1. Physical technology and processes

Physical recycling is to process the internal components of used power batteries, such as electrode active materials, current collectors and battery casings, through a series of means such as crushing, sieving, magnetic separation, fine crushing and classification to obtain valuable products, which can then be recycled The next step in the recycling process. The core process is material repair after crushing and screening, which is a relatively pure physical process. The representative company is Suny Group. The advantage is that it can be disassembled with all components, fully automatically and without pollution, and the lithium iron phosphate battery can be recycled, which is very economical. The disadvantage is that it is labor-intensive and difficult to recover other valuable metals.

2. Wet process and process

Wet recycling is to dismantle and pre-treat used batteries and dissolve them in acid-base solutions to extract some valuable metal elements, and then extract the remaining valuable metals through ion exchange and electrodeposition, which mainly includes chemical precipitation, Three methods including solvent extraction and ion exchange. The core process of the wet method is to add chemical reagents to the electrode powder for leaching and extraction

3. Fire process

Fire recycling refers to the direct recycling of various battery materials or metals without using media such as solutions, and mainly includes mechanical sorting methods and high-temperature electrolysis methods. Generally, it is necessary to peel off the battery outer shell, mix the inner core of the battery with coke and limestone, and undergo reduction and roasting to obtain metal lithium, cobalt, nickel, aluminum, etc. to form a carbon alloy; the fluorine, phosphorus, etc. in the electrolyte are solidified in the slag and can be used Additives to building materials or concrete. Then deep processing is carried out, and the whole process is completed at high temperature. The core process of the fire method is high-temperature pyrolysis to obtain metal oxides. Representative companies are Zhongwei Cycle and Umicore. The advantage is that the process is simple and more heavy metals such as mercury, nickel and zinc can be recovered; the disadvantage is that the yield is low, the energy consumption is high, and a certain amount of waste pollution will be produced

Now we are using Physical Recycling Methods to process Waste Lithium Batteries,it's a more safety ,green way to recycling batteries.
