How to recycle and reuse scrap lithium batteries?

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 used lithium batteries, recycling and utilization of used lithium batteries?

1. The material from the conveyor is sent to the primary crusher for coarse crushing, the coarsely crushed material is sent to the secondary crusher through the conveyor for secondary crushing, and the material crushed by the secondary crusher enters the conveyor and the magnetic separation is set at the same time The equipment can separate the iron in the material. After the iron is removed by the material conveyor and magnetic separator, it enters the three-crusher for fine crushing, and the material is crushed to powder.

2. The material in powder state enters the cyclone separator through 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 the materials of different densities are stratified to obtain the metal fraction. Selected, 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.

3. The separation in the lithium battery recycling equipment is composed of magnetic separation, wind separation, etc. Magnetic separation can separate the ferromagnetic material in the crushed material; the wind separation can separate the powder in the crushed material and the lighter plastic diaphragm Part of the volatile electrolyte adhering to the material is extracted with the wind; the pretreatment and recycling of waste lithium ion batteries is mainly to use the recycled waste lithium batteries after discharge, and use mechanical equipment to crush, winnow Crushing, 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.
