Which process should be used to recycle waste lithium batteries

Lithium battery recycling and processing equipment physically disassembles the recovered waste lithium batteries, sorts battery shells, crushes and screens, removes powder from positive and negative electrodes and pumps films, crushes and removes powder from positive and negative electrodes, aggregates copper and aluminum from positive and negative electrodes, separates copper and aluminum from positive and negative electrodes, and other mature processes to realize resource regeneration and recycling of decommissioned power batteries. The recovered black powder has the characteristics of high economic value and strong practicability for reuse.

The crushing device divides the entire power lithium battery into sheet-shaped separators, positive and negative electrodes, aluminum shells, and some powder that falls from the electrodes. The separator separator is used to separate the separator from the pole plate, separate the powder from the electrode, and process the broken and charged waste battery core and positive electrode sheet. The positive electrode sheet of the waste ternary lithium battery is subjected to high-temperature pyrolysis, sorting, separation and other treatment processes to separate the positive and negative electrode powder, aluminum sheet, copper sheet and shell. Recycling and processing process of scrapped ternary lithium batteries: Discharge the scrapped batteries in salt water, then perform mechanical crushing after high temperature pyrolysis, the crushed materials go through a magnetic separator to remove iron, and the remaining materials go through particle size sorting to screen out battery materials. The battery materials are subjected to secondary crushing and particle size sorting again, and the purer battery materials are separated from copper and aluminum by density sorting.
