N1 - Funding Information: informationDirectorate-General for Internal Market, Industry, Entrepreneurship and SMEs, Grant Number: Administrative Arrangement No. SI2.790994.The current work was developed using the results achieved from the MSA of five battery raw materials, which are described in a JRC MSA report (https://doi.org/10.2760/519827) and individual publications of the authors. The five MSAs were carried out in the context of an administrative arrangement between the Joint Research Centre and (JRC) Directorate General for Internal Market, Industry, Entrepreneurship, and SMEs (DG GROW) (Contract number SI2.790994). The authors acknowledge the contributions of the participants in the validation workshops of the five MSA held in September 2019. The authors would like to thank Constanze Veeh from DG GROW for the supervision of the MSA policy dossier ensuring that this work serves the policy needs. Publisher Copyright: © 2022 The Authors.

N2 - Lithium-ion batteries (LIBs) will play a crucial role in achieving decarbonization and reducing greenhouse gases. If the EU wants to be competitive in the global market of LIBs, it has to ensure a sustainable and secure supply of the raw materials needed for the manufacturing of these batteries. Limited understanding of how the battery material cycles are linked with raw materials supply chains may hinder policy measures targeting the set-up of a domestic supply chain in the EU since no precise information on where to intervene will be available. The novelty of this work lies in a multilayer system approach developed to reveal interlinkages between the flows of five raw materials contained in LIBs (cobalt, lithium, manganese, natural graphite, and nickel) in the EU. This was achieved by aligning material system analysis datasets of raw materials contained in LIBs with datasets on stocks and flows of this type of batteries in the EU. The results demonstrate the EU's strong import dependency on LIBs and battery raw materials. The EU recycling of lithium and natural graphite is low/nonexistent hindering the sustainable supply of these materials. The results also show that the majority of battery materials are increasingly accumulated in use or hoarding stocks. The proposed approach is designed to help identify bottlenecks and possible solutions to increase the efficiency of the EU LIB system, which could go unnoticed if each material supply chain were examined individually. This study also highlights how the lessons learned can support EU resource-management policies.
