How to deal with the lithium batteries of new energy vehicles after they are scrapped?
After the new energy vehicle battery is scrapped, two methods will be adopted: step-by-step utilization and dismantling and recycling. Ladder utilization The current common new energy vehicle batteries usually have more than 60% of the energy storage capacity when they are scrapped. It is too wasteful to disassemble and recycle directly. These power batteries can be used by companies that do not pay much attention to battery performance, such as energy storage batteries in power stations, energy storage batteries in residential buildings, and emergency power storage. This step-by-step reuse can make full use of the full life cycle of the power battery.

After the dismantling and recycling ladder is used up, the power battery needs to be dismantled and recycled. The previous lead-acid batteries polluted a lot, compared with the current mainstream lithium iron phosphate batteries, which are much more environmentally friendly. It does not contain mercury, cadmium, lead and other toxic heavy metal elements, and phosphorus, acid, iron and lithium elements can be recycled and reused. To dismantle and recycle scrapped lithium batteries, a special lithium battery crushing and recycling production line is required. The general recycling process is as follows:
1. The waste lithium battery to be treated is sent to the loading platform through the step ladder or other transfer equipment, and then the waste lithium battery is put into the feeding port in the discharge mechanism. After the lithium battery is fully discharged, the lithium battery is discharged from the edge of the discharge port. The slip sheet is transported to a twin-shaft shredder for shredding processing.
2. After secondary crushing through a hammer crusher to ensure sufficient material crushing, the iron and other metals in the lithium battery are collected by a magnetic separation conveyor, and then other mixed materials are transported to a specific gravity separator for screening.

3. The material is sieved into carbon, lithium powder, copper, aluminum, etc. through the specific gravity separator. In addition, the dust-containing gas in the process of crushing and conveying is treated by a pulse dust collector, which can reduce the dust-containing rate of the workshop on the one hand. On the other hand, carbon and lithium powder in the dust-containing gas can be recovered.
Equipment advantages:
(1) Advanced technology, mature technology, reliable equipment, low investment, low consumption and high;
(2) It can process waste lithium-ion batteries of all specifications and models listed in the product outline, such as cylinders, soft bags, plastic shells, steel shells, aluminum shells, positive and negative electrode sheets;
(3) The automatic control system should be produced according to the normal operation of the unit, and the processed pole pieces meet the subsequent process requirements and various process and physical properties.
