Name
End-of-life LFP battery Existing pyrometallurgy process
Use advice for data set When using the data set for life cycle assessment of the described pyrometallurgy recycling process, ensure that the functional unit is consistent with 1 kWh of battery capacity. This data must be distinguished from other recycling processes, and it should be noted that the information provided is derived from multiple papers. Attention should be given to methodological consistencies, such as system boundaries, assumptions on the efficiency of the recovery process, energy inputs, as well as emissions during the recycling steps. Users must ensure that the technological applicability is compatible with similar end-of-life battery treatments and is representative of the actual recycling practices.
Technical purpose of product or process The pyrometallurgical process described is utilized for the recycling of end-of-life (EoL) lithium iron phosphate (LFP) batteries. This specific procedure, involving disassembly, crushing, high-temperature sintering at 1400℃, acid leaching, solvent extraction, and a final roasting step at 900℃, is targeted at recovering valuable materials, particularly lithium and cobalt, in the form of lithium cobalt oxide (LiCoO2). The recovered compounds are vital for manufacturing new batteries or for other applications requiring these materials.
Classification
Class name : Hierarchy level
  • ILCD: End-of-life treatment / Material recycling
General comment on data set Fully discharged EoL LFP batteries are first disassembled and crushed. The battery material is then processed through a 1400℃ smelting (or sintering) process. This is followed by acid leaching and solvent extraction. Finally, oxidation and roasting at 900℃ to obtain LiCoO2.

Functional Unit using 1 kWh as the functionalunit
Technological representativeness
Technology description including background system The organic binder is removed by calcination, the lithium iron phosphate powder is separated from the aluminum foil, and the lithium iron phosphate material is obtained, and then an appropriate amount of raw material is added to it to obtain the required molar ratio of lithium, iron and phosphorus, and a new lithium iron phosphate is synthesized by high temperature solid phase method.
