What technology is used to recycle lithium batteries?

The recycling process of waste lithium battery mainly has two ways: dismantling plus recycling and cascade utilization. At present, through the cascade utilization equipment can be tested on the lithium battery reorganization and recycling again, and then through the lithium battery recycling equipment can be dismantled and recycled waste lithium batteries.

1 Cascade utilization

 Cascade utilization is mainly for battery capacity down to the original 70% -80% can not continue to use the battery in electric vehicles. Cascade utilization can continue in other areas, such as power storage, low-speed electric vehicles, hardware tools, etc. They can be used as a power source for some time. Through the process of carrying out the necessary inspection and testing, classification, splitting, battery repair or reorganization of used power storage batteries into gradient products, so that they can be applied to other fields.

The cascade utilization of decommissioned power batteries can extend the service life of the battery that fully leverage the remaining value of batteries, promote the use of new energy recycling, alleviate the pressure of recycling caused by the current large volume of battery decommissioning, reduce the industrial cost of electric vehicles which drive the development of the new energy automobile industry.

2 Dismantling and recycling

First of all, through the lithium battery recycling equipment for various types of lithium batteries for initial crushing, such as cylindrical batteries, soft pack batteries and hard shell batteries. The waste lithium batteries are shredded into small pieces. The shredded material is separated from diaphragm paper by airflow sorting machine, while magnetic separator equipment is set to separate iron and nickel strips. Finally, the black powder is separated by linear vibrating screen, and the copper and aluminum are separated by specific gravity sorting machine. Lithium battery recycling equipment ensures the efficient recovery of resources through precise control system and efficient crushing method.

The whole line of lithium battery recycling equipment is equipped with environmental protection systems, such as spray tower, pulse dust collector, activated carbon adsorption box and UV photo-oxidation which can collect and purify the dust and harmful gases generated during the operation of the whole set of equipment.
