Use advice for data set
The life cycle assessment data pertaining to the advanced hydrometallurgy process for LFP batteries should be used carefully, considering the unique aspects of the recycling process. The functional unit for this data set is 1 kWh of battery capacity. Users need to ensure that comparisons or assessments are made on a similar basis and scale. Attention should be given to methodological choices, such as the allocation of environmental impacts between the recycled product and the original waste stream. It is important to note that the data come from multiple papers and may contain variability that could affect the outcome of the analysis.

General comment
Before adopting wet process for material recovery, the waste lithium iron phosphate batteries are safely discharged, disassembled, pyrolyzed, mechanically crushed, and sorted to get powdered lithium-containing waste. Lithium-containing material is added to leaching solvent for leaching, filtered and separated to get lithium-containing solution, added to the purification agent for reaction, filtered, concentrated, and under certain reaction conditions, added to the precipitation agent fully reacted to crystallization and precipitation, filtered, washed and dried to get battery-grade lithium carbonate.

Technical purpose
The advanced hydrometallurgy process described is specifically used for the recovery of materials from waste lithium iron phosphate (LFP) batteries. The end product is battery-grade lithium carbonate, which is a critical raw material for the manufacturing of new lithium iron phosphate batteries, as well as other lithium-based chemical products.
