The working process of lithium battery recycling plant

The positive electrode of lithium battery is mainly composed of lithium cobalt oxide, lithium manganate, lithium iron phosphate and ternary lithium materials (lithium nickel cobalt manganese oxide, lithium nickel oxide), etc. The current mainstream lithium battery cathode material is mainly lithium iron phosphate and ternary materials. The cathode material accounts for 30% - 40% of the cost of lithium-ion batteries, which directly affects the energy density and performance of lithium battery packs.

The negative electrode of the lithium battery is the main component of the lithium battery. It is made by mixing the negative electrode active material, the binder and the additive into a paste, which is evenly spread on both sides of the copper foil, dried and pressed.

Lithium battery positive and negative electrode sheet processing equipment processing process of positive and negative electrode sheet:

1. First-level shredding: Press the start button of the shredder after the lithium battery positive and negative sheet processing equipment is powered on, and the material is fed to the shredder through the conveyor for shredding.

2. Secondary crushing: The crusher will shred the material that has been shredded by the pole piece again, and the multi-knife crusher will roughly crush the material of the lithium battery pole piece. The material is discharged through the discharge port of the crusher.

3. Vibration screening: Multi-stage screening of various crushed materials is carried out through the large vibrating screen equipped in the production line of the lithium battery positive and negative plate processing equipment.

4. Three-stage pulverization: The sieved materials are transported to the pulverizer through negative pressure and then subjected to three-stage fine powder. After the pulverization is completed, after screening, the black powder we need is obtained.
