Lithium-ion Battery Recycling Process

The processing of scrapped lithium batteries is a technology-intensive and costly task. By using our electronic waste recycling equipment to process lithium-ion batteries, recycling efficiency can be improved. If you are interested in lithium-ion battery recycling equipment, please click here.
It first uses a conveyor to send the waste lithium batteries to the primary shredder for preliminary shredding. This process will tear the scrapped lithium batteries into smaller pieces for subsequent processing. The shredded materials are sent to the secondary shredder through the conveyor for deeper shredding. The purpose of this step is to crush the materials into smaller particles for subsequent sorting and extraction.

The secondary shredded materials enter the conveyor. During this process, we set up magnetic separation equipment, so that the iron part can be sorted out from the materials, which improves the recycling rate of resources.

The sorted materials are sent to the airflow sorter through the conveyor. The induced draft fan and the cyclone feeder are used to separate the diaphragm paper in the positive and negative electrodes. Then the sorted positive and negative electrodes enter the third-stage shredder for fine shredding. The goal of this step is to crush the materials to a particle size of about 20 mesh, making further extraction and separation smoother.

The crushed material passes through the conveyor and enters the linear screening machine to screen out the black powder. Then, the successfully ground copper and aluminum pass through the conveyor to the specific gravity separator to sort out copper and aluminum. The unsuccessfully ground materials enter the grinder again and pass through the linear screen and specific gravity separator again to successfully obtain the separated copper and aluminum.

All ultrafine dust is introduced into the pulse dust collector by the negative pressure system for collection. This step is designed to prevent dust from polluting the environment. The filtered exhaust gas will continue to be sent by the negative pressure system to the exhaust gas treatment equipment for air purification. This process is to ensure that the exhaust gas emissions meet the national environmental protection standards. Only after this step can the cleaned exhaust gas be discharged into the environment. In general, this treatment process fully reflects the concept of environmental protection and resource recycling, and realizes the high-efficiency and high-quality recycling of lithium battery waste materials.
