RESOURCE RECLAMATION AND ENVIRONMENTAL PROTECTION METHOD FOR RECYCLING LITHIUM ION BATTERY WASTES

摘要

Disclosed is a resource reclamation and environmental protection method for recycling lithium ion battery wastes. The method comprises: placing a battery cell after being crushed and separated into a high-temperature liquid, so that a diaphragm in the battery cell is decomposed through heating of the high-temperature liquid into gas and/or oil to be discharged; and separating a positive pole material from a positive pole current collector and separating a negative pole material from a negative pole current collector through heating of the high-temperature liquid, to obtain a mixture containing the positive pole material, the negative pole material, the positive pole current collector having a positive pole tab, the negative pole current collector having a negative pole tab, and the high-temperature liquid, the temperature of the high-temperature liquid being not lower than the temperature of decomposition and/or separation of an adhesive. The present invention can not only achieve re-utilization of resources of the lithium ion battery wastes, but also achieve separation and recycling of various composing resources; the recycling process is environment-friendly; the method is applicable to the recycling of lithium ion battery wastes in any form and can be widely applied; the recycling operation is simple, the cost is low, and mass production can be easily realized.
