Process Data set: NCM pyrometallurgical recycling(LCIA) (en) en zh

Key Data Set Information
Location CN
Reference year 2018
Name
NCM pyrometallurgical recycling(LCIA)
Use advice for data set Users of this data should ensure they apply the CML2001 model with GaBi6 software, version 6.0, for assessing environmental impacts. Consideration of the entire life cycle of the power system, particularly focusing on a vehicle traveling distance of 250,000 km as the functional unit, is crucial. Attention should also be paid to the classification, characterization, and normalization of environmental impacts when using the LCI results provided by Brunp. User should verify if recycling credits are to be included or excluded according to the methodological choices of the specific LCA study.
Technical purpose of product or process The reprocessed NCM material obtained through this pyrometallurgical recycling process is used for manufacturing new NCM cathodes, which serve as a critical component in lithium-ion batteries for electric vehicles and various electronic devices.
Classification
Class name : Hierarchy level
  • ILCD: End-of-life treatment / Material recycling
General comment on data set The waste NCM battery is first pretreated to get the positive electrode powder, iron, aluminum, copper, and others, after dissolving the positive electrode powder, precipitation, and removal of impurities, and finally roasted to get the new NCM.
