The waste battery undergoes disassembly, dry pyrolysis, crushing and mechanical sorting, acid leaching, copper removal, iron and aluminum removal, rough extraction, fine extraction, and alkali aging to obtain a ternary precursor. Users of this data set should note that the recovery process is specific to used lithium batteries and the functional unit reflects the output based on a 12.717g used lithium battery as input. The life cycle assessment should take into consideration the regional technological applicability and potential technological advancements in recycling. It is critical to address the allocation of environmental burdens in the case of multifunctional processes. Users must ensure that their system boundaries and assumptions align with these methodological considerations when utilizing the data for environmental impact studies or for developing eco-design strategies.
