Recycling of LFP Lithium Battery

Lithium iron phosphate battery is widely used in passenger cars, buses, logistics vehicles, low-speed electric vehicles and other fields due to its safety, low cost and other advantages. In addition to the characteristics of lithium iron phosphate battery, it also has the ability of instantaneous large mobility output. Therefore, lithium iron phosphate batteries occupy a large part of the total battery shipments. When the lithium iron phosphate battery reaches the end of its service life, how should we deal with these used lithium iron phosphate batteries? Generally we have two processing methods, one is the gradient utilization, the other is the use of lithium battery recycling equipment crushing recovery.

1 Echelon use, laddering utilization is also the use of the value of the used lithium battery testing, disassembly and reassembly into a new battery, or a larger capacity battery. After they are tested without problems, they are put back into the market.

2 Crushing and recycling, all the used lithium batteries will enter the crushing and recycling stage in the end. First of all, the battery can no longer be used for secondary utilization of lithium battery discharge equipment to discharge, discharge the battery can be more secure recycling. Then it is sent into the lithium battery recycling equipment for shredding, drying, crushing, at the same time, the airflow sorting machine according to the weight of the light plastic diaphragm will be screened and collected into the diaphragm box, the magnetic separator will be separated out with magnetic materials. The remaining material will be crushed again and screened out a certain amount of black powder by linear vibrating screen, and finally copper and aluminum can be separated by copper-aluminum specific gravity sorting machine. The whole recycling process we can get black powder, copper and aluminum particles, iron shells and nickel strips and so on.

3 economic benefits, the recycled materials, which is valuable enough is the black mass, which contains high value of lithium cobalt, can be sold, lithium price is very high, the enterprise can get economic benefits.

Lithium iron phosphate battery recycling is necessary to strengthen the research and development of lithium battery recycling equipment to improve recycling efficiency.
