The advantage of the lithium battery pole piece is that it can reduce the surface energy of the foil and improve the wettability of the slurry, thereby improving the bonding performance of the positive electrode material and the current collector (aluminum foil), reducing the phenomenon of powder falling during the battery cycle, and making the battery The cycle life is longer, and the content of the binder in the slurry can be reduced to increase the utilization rate of the active material.

Lithium Battery Recycling Machine

The process of lithium battery processing equipment is from the conveyor material into the primary crusher for coarse crushing, the coarse 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 at the same time Set up magnetic separation equipment to 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 materials in the process powder state of the lithium battery processing equipment enter the cyclone separator from the negative pressure system for air filtration, and fall to the air separator through the fan, and are sorted by the air separator to separate the materials of different densities. The obtained metals are sorted out, and all the 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 pretreatment and recycling equipment for scrap lithium batteries is mainly responsible for the full discharge of used lithium ion batteries, the crushing of lithium ion batteries, the sorting of various materials after crushing, and the collection of materials after crushing to ensure the requirements of the next process.

Lithium battery processing equipment technology and necessary safety protection and dust removal and purification equipment. The separation in the lithium battery crushing and recycling equipment consists of magnetic separation and winnowing. Magnetic separation can separate the ferromagnetic materials in the crushed material; the winnowing can separate the powder in the crushed material and the lighter plastic diaphragm, etc. Sort out, and at the same time extract part of the volatile electrolyte adhered to the material with the wind;

The pretreatment and recycling of waste lithium-ion batteries is mainly to use mechanical equipment for crushing, winnowing, crushing, gravity sorting, screening and other processes after discharging the recycled waste lithium batteries, so that the active materials on the positive and negative pole pieces are combined with the active materials on the positive and negative poles. The copper and aluminum foils are effectively separated, and the battery is processed into materials containing valuable metals.
