LIB Hydrometallurgy--Alkaline leaching(Process F)
Use advice for data set Users leveraging this data set should note that recycling or treatment of plastic and metal shells is excluded from this analysis, as are labor costs, factory construction costs, and their environmental impact. This data is specific to conditions in China and may not represent the process in other countries. Users should consider time relevance as data represents an average from 2013-2017, and adjust for changes in technology or processes that have occurred since then. Stakeholders should integrate this data with information from LIB manufacturers, recyclers, and official Chinese agencies to ensure a comprehensive assessment. When applying this data, it is important to adhere to the methodological advice that encapsulates 'cradle to grave' processes.
Technical purpose of product or process The alkaline leaching process (Process F) in Hydrometallurgy is specialized for selective extraction of lithium (Li), nickel (Ni), and cobalt (Co) from ternary cathode materials without leaching manganese (Mn) and aluminum (Al). This process is mainly utilized in the recovery and recycling of critical metals from spent lithium-ion batteries (LIBs). Given its alkaline nature, the process enables conservation of alkali usage during the precipitation recovery of products.
Classification
Class name : Hierarchy level
  • ILCD: Unit processes / End-of-life treatment / Material recycling
General comment on data set The ammonia/ammonium salt system can leach Li, Ni and Co from the ternary cathode materials without leaching Mn and Al. The selectivity is good and the system is alkaline, so the amount of alkali can be saved in the recovery of the products by precipitation method.

Data selection and combination principles The input-output of the process comes from the average results of the data reported in the literature review, reflecting the representative process from "tomb" to "cradle". This study does not consider the recycling or treatment of plastic and metal shells, and labor costs, factory construction costs, and their impact on the environment are also not included in this analysis.
Deviation from data selection and combination principles / explanations None
Data treatment and extrapolations principles It is worth noting that the EU's data is not specific to a specific industry, and some import and export data and recycling information are not suitable for China's situation. Therefore, the improved CRMs evaluation method also combines official Chinese data, literature reports, and data from other interest groups such as trade/industry associations to conduct the best estimation of data from major LIB manufacturers, recycling companies, official management agencies in China, and other stakeholders. In terms of data timeliness, the reference period used in the evaluation of CRMs is based on the latest 4-year average (i.e. 2013-2016).
