| Use advice for data set | 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. |
| Technical purpose of product or process | The hydrometallurgical recovery process detailed in this data set is employed for the recycling of used lithium batteries. During the process, the batteries are disassembled and go through dry pyrolysis, crushing, and mechanical sorting, followed by acid leaching, and the removal of copper, iron, and aluminum. The subsequent rough and fine extraction stages, along with alkali aging, result in the production of a ternary precursor. This precursor is commonly used in the manufacture of new lithium batteries, serving as a valuable resource in the battery supply chain. |
