Waste lithium battery recycling equipment dismantling end-of-life battery material recovery process generally includes battery pack discharge, single battery destructive dismantling, shredding, sorting and electrode material recovery process. Electrode materials contain valuable metals, the recovery value is high, and there are more processes on the recovery of electrode materials. The existing electrode material recovery technology mainly includes dry recovery technology, wet recovery technology and biological recovery technology. Bio-recycling technology is still in the laboratory stage, the process requires high costs; dry recycling technology is suitable for large-scale industrial production, there are also relevant companies for production lines put into operation.
Waste lithium battery recycling equipment: power lithium-ion batteries do not contain Pb, Cd, Hg and other heavy metal pollutants, but the end-of-life power lithium-ion batteries still have some harm to the environment. Single power lithium-ion battery mainly includes positive electrode, negative electrode, diaphragm, electrolyte and shell, etc..
The positive electrode generally uses aluminum foil as the collector substrate, and the front and back of the aluminum foil is coated with positive ji material, which consists of a certain proportion of positive active material (LFP, ternary material), conductive agent (acetylene black, carbon nanotubes, etc.) and binder (polyvinylidene fluoride).
The negative electrode generally adopts copper foil as the collector base material, and the front and back side of the base material are coated with negative ji electric ji material, which consists of a certain proportion of active material (mostly graphite), dispersant (sodium carboxymethyl cellulose) and binder (styrene butadiene rubber).
Waste lithium battery recycling equipment: electrolyte mainly contains organic solvents (vinyl carbonate, ethylene carbonate, dimethyl carbonate, propylene carbonate, etc.) and electrolyte solutes (LiPF6, LiBF4, LiClO4, etc.). Therefore, it is important to recycle the end-of-life lithium battery materials for environmental protection.
