| Abstract: | The recycling process of spent Ni-Co-Mn (NCM) batteries was systematically introduced, including discharging, pretreatment, pyrometallurgical and hydrometallurgical processes, as well as recycling of electrolyte. Based on the comparison of the advantages and disadvantages of each process, it is proposed that the combination of pyrometallurgical and hydrometallurgical processes be suitable for spent NCM batteries recycling. The corresponding pollution controlling methods aiming at the contaminants generated in each process were also provided. It is expected to provide a reference for environmentally friendly recycling of spent NCM batteries. |
