Status in recovery process and regeneration technology of spent Li-ion battery
The demand for Li-ion battery is increasing day by day.The following problem is how to properly handle spent Li-ion battery.The resource utilization of Li-ion battery can greatly alleviate the shortage of valuable metal resources in China and contribute to environmental protection.The technological progress in the recycling and cyclic regeneration of spent Li-ion battery in recent years is summarized,and the main processes being put into operation by major enterprises are summarized.The primary domestic enterprises in China include Green Eco-Manufacture,Brunp Recycling and Huayou Cobalt,the primary foreign enterprises include European Umicore and French Recupyl.Most domestic and foreign enterprises tend to use mechanical crushing followed by pyrometallurgical and hydrometallurgical recycling processes for industrial production,while a few foreign enterprises use manual disassembly,cryogenic crushing,or their own patented technologies to recycle black mass.
