99% Separation Rate Fully Automatic Waste Battery Recycling Production Line Lithium Battery Stripping

Lithium battery mainly consists of shell, positive electrode, negative electrode, electrolyte anddiaphragm. The positive electrode is formed by coating lithium cobaltate powder on two sides ofan aluminum foil current collector through PVDF which plays a bonding role.The negative electrode structure is similar to the positive electrode and consists of carbon powder bonded toboth sides of the copper foil current collector. At present, the research on the recycling of wastelithium batteries is mainly focused on the recovery of high-value anode precious metals cobaltand lithium. Copper in the negative electrode of waste lithium battery (content up to 35%) is animportant production raw material widely used.Carbon powder adhered to it can be used asadditives such as plastics and rubber. Based on the structural characteristics of lithium batteries, our company adopts an environmentally-friendly physical separation process to realize efficientseparation and recovery of waste lithium batteries.

Commonly used lithium battery recycling methods include hydrometallurgy, pyrometallurgy, and mechanical physical methods. Compared with the wet method and fire method, the mechanical physical method does not need to use chemical reagents, and has lower energy consumption. It is an environmentally friendly and efficient method.

The pretreatment process of waste lithium ion batteries mainly comprises the following steps: after discharging the recovered waste batteries, crushing, magnetic separation, air separation, crushing, gravity separation, screening and other processes are carried out by mechanical equipment, so that the powder on the positive and negative pole pieces is effectively separated from thecopper aluminum foil, and the batteries are treated as valuable materials.
