摘要 | Different from the traditional pyrometallurgical recovery process of Li and Co from spent lithium-ion batteries, a new recovery method for Li and Co was established by converting LiCoO2 into water-soluble metal sulfates by roasting a mixture of LiCoO2 and NaHSO4 center dot H2O. The evolution law of the mixture with increased roasting temperature was investigated by thermogravimetry-differential scanning calorimetry(TG-DSC), in situ X-ray diffraction(XRD), XRD, and X-ray photoelectron spectroscopy(XPS). The results show that the phase transition of LiCoO2 mixed with NaHSO4 center dot H2O with increased temperature proceeded as follows: LiCoO2, NaHSO4H2O -> LiCoO2, NaHSO4 -> Li1-xCoO2, LiNaSO4, Na2S2O7, Na2SO4 -> Li1-xCoO2, Co3O4, LiNaSO4, Na2SO4 -> Co3O4, LiNaSO4. The reaction mechanism of this roasting process may be as follows: LiCoO2+NaHSO4 center dot H2O -> 1/2Li(2)SO(4)+ 1/2Na(2)SO(4)+1/3Co(3)O(4)+1/12O(2)+3/2H(2)O, Li2SO4+Na2SO4=2LiNaSO(4). |
