| Abstract Scope |
The production of spent lithium-ion batteries (LIBs) is expected to increase rapidly with the rapid development of new energy vehicles. Without proper disposal, the spent LIBs will cause a waste of resources and a threat to the environment. The route of carbothermal reduction followed by magnetic separation has been proven an efficient process to recover valuable metals from spent LIBs. This paper investigated the reductive roasting behaviors of the spent cathode material under microwave-assisted reduction using biochar as the reductant. Experimental results show that the chemical phases of spent cathode material were converted into Ni-Co alloy, MnO and Li2CO3, wherein Li2CO3 can be extracted by water leaching, and the Ni-Co alloy can be recovered by magnetic separation. |
