METHOD FOR DISASSEMBLING AND SEPARATING WASTE LITHIUM-ION BATTERY

摘要

A method for disassembling and separating a waste lithium-ion battery, comprising: directing tearing a battery pack or a cell of the waste lithium-ion battery with water and electricity without discharging after a housing is removed; then performing first wet screening; directly performing wet degumming without drying after an electrolyte is recovered and iron is removed by magnetic separation; then performing first water-carrying pulverization, third wet screening, and second water-carrying pulverization after second wet screening is performed; and finally, performing jigging separation to obtain copper powder, aluminum powder, anode and cathode materials, plastic powder, and diaphragm pulp.
