Lithium battery mainly consists of shell, positive electrode, negative electrode, electrolyte and diaagm. The positive electrode is formed by coating lithium cobaltate powder on two sides of an 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 to both sides of the copper foil current collector. At present, the research on the recycling of waste lithium batteries is mainly focused on the recovery of high-value anode precious metals cobaltate lithium. Copper in the negative electrode of waste lithium battery (content up to 35%) is an important production raw material widely used.Carbon powder adhered to it can be used as additives such as plastics and rubber. Based on the structural characteristics of lithium batteries,our company adopts an environmentally-friendly sical separation process to realize efficient separation and recovery of waste lithium batteries.
The pretreatment process of waste lithium ion batteries mainly comprises the following steps:afterdischarging 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.
