Spent ternary lithium batteries originate from electric bicycles, electric vehicles, electric equipment, and tools. After dismantling, power batteries that cannot be reassembled following testing are subjected to resource recovery. In this dataset, the resource recovery method for spent ternary lithium batteries is recycling regeneration technology. This process involves pretreatment, acid leaching, extraction and purification, synthesis of ternary precursors, and synthesis of ternary battery materials to recover cathode materials. Subsequently, through regeneration processes such as reaction and separation, cathode-active metals (nickel, cobalt, manganese, lithium) and other metals (copper, aluminum) are recovered. This dataset is applicable to the process of resource recovery of retired ternary lithium batteries using recycling technologies.
