Abstract
The procedure of the recycling method is to cut the used lithium ion battery and take out the positive plate, process the positive plate with heating process to remove the bond between the aluminum foil and the positive pole material, by means of the mechanical or ultrasound shaking, the aluminum foil and the positive pole material are separated, process the positive pole material with the high-temperature handling, the content of the element in the positive pole material is analyzed. Mixing the lithium compound based on the supplement of the cobalt manganese or the nickel. After high-temperature and grinding processing, the positive pole material with excellent performance is recycled.
