Abstract:
Recycling the major components of the spent lithium-ion batteries (LIBs), such as lithium and cobalt and other hazardous materials, appears to be a useful method to inhibit environmental contamination and raw material utilization. In this work, a novel pyrometallurgical process is developed for separation and recovery of cobalt and lithium from spent lithium-ion batteries. The main material used in cathode is LiCoO2 in the form of ground fraction principally containing cobalt and lithium. The ground fraction is mixed with carbon and pressed into pellets for the reduction reaction to take place. The carbon used in this reaction is chosen from carbon produced in a waste tire recycling process. The characterization of the reaction products shows that cobalt can be recovered as metallic cobalt and lithium as Li2CO3. This pyrometallurgical process is adequate and easy for recovery of cobalt and lithium from spent lithium-ion batteries.
