| 英文摘要 | Spent lithium-ion secondary battery (LIB) is one important kind of waste electric and electronic equipment (WEEE). At present, technologies available for spent LIBs recycling include chemical deposition, solvent extraction, Etoile-Rebatt process, electrodeposition, floatation and ion-exchanging. In this paper, a novel vacuum-aided pyro-metallurgical process for recovery metallic Co directly from waste LIBs was presented. The experiment results showed that 1) the decomposition and reduction rates of LiCoO2 increased with the increase of experiment temperature; and 2) metallic Co can be recovered successfully when the experiment temperature was higher than 700 C and the system pressure was maintained at 10 Pa. XRD and SEM results obtained at different temperatures showed that, in this paper, LiCoO2 was first reduced to CoO at a lower temperature and then it was reduced to metallic Co as the increase of temperature. This vacuum-aided pyrometallurgical process might be a promising one for spent LIBs recycling. |
