How to recycle used lithium batteries

Time:2021-04-30 09:59 Author:Suny Group

At present, the recycling rate of lithium batteries is very low, and a large number of used lithium batteries are abandoned, which poses a huge threat and pollution to the environment, and is also a waste of resources. Analysis shows that lithium-ion batteries contain an average of 12%-18% cobalt and 1.2% lithium~ 1.8%, copper 8%~10%, aluminum 4%~8%, shell alloy 30%. How to deal with waste lithium batteries, recycling and utilization of waste lithium batteries? The materials are sent by the conveyor to the primary crusher for coarse crushing, and the coarsely crushed materials are sent to the secondary crusher through the conveyor for secondary crushing, and crushed by the secondary crusher. After the material enters the conveyor, a magnetic separation device is set at the same time, which can separate the iron in the material. After the material conveyor and magnetic separator remove the iron, they enter the three-crusher for fine crushing and crush the material to powder.

The material in powder state enters the cyclone separator from the negative pressure system for air filtration, and falls on the air separator through the fan, and is sorted by the air separator, so that substances of different densities are stratified to obtain metal separation. , And all non-metals are brought into the pulse dust collector by the negative pressure system for concentration. The filtered tail gas will continue to be sent from the negative pressure system to the tail gas treatment equipment for air purification, so that it can meet the emission standards before being discharged at high altitude.

The separation in the lithium battery recycling equipment is composed of magnetic separation, wind separation, etc. Magnetic separation can separate the ferromagnetic materials in the crushed material; the wind separation can equally divide the powder in the crushed material and the lighter plastic diaphragm. At the same time, part of the volatile electrolyte adhering to the material is drawn out with the wind; the pretreatment and recycling of waste lithium-ion batteries is mainly to use mechanical equipment for crushing, winnowing, smashing, and recycling of waste lithium batteries after discharge. Gravity sorting, sieving and other processes can effectively separate the active material on the positive and negative pole pieces from the copper and aluminum foil.
