L2E (Laboratoire d'électrochimie et d'électrométallurgie) is a French research laboratory specializing in electrochemical processes and metallurgical applications, based in Grenoble and affiliated with Université Grenoble Alpes, Grenoble INP, and CNRS. Founded to bridge fundamental electrochemistry and industrial electrometallurgy, the laboratory has contributed to battery research, corrosion science, and metal extraction, collaborating with industrial partners such as Renault, ArcelorMittal, and Solvay. L2E operates within regional innovation networks including Minatec and GIANT campus, and interfaces with European programs like Horizon 2020 and ERC grants.

History

L2E traces origins to mid-20th-century French institutes linked to École Centrale de Lyon, École des Mines de Paris, and Institut National Polytechnique de Grenoble, evolving through partnerships with CNRS and Commissariat à l'Énergie Atomique. Milestones include projects funded by Agence Nationale de la Recherche and collaborations with CEA, Schlumberger, and PSA Group, and participation in initiatives aligned with European Commission policies and Horizon Europe. Directors and researchers have interacted with figures from Université Paris-Saclay, Imperial College London, Massachusetts Institute of Technology, and ETH Zurich through visiting professorships and joint labs.

Research Areas

L2E's program covers applied electrochemistry and electrometallurgical engineering, with emphasis on lithium-ion batteries, sodium-ion batteries, and redox flow batteries studied in conjunction with researchers from Stanford University, University of Oxford, and University of Cambridge. Other themes include corrosion mechanisms informed by work from Delft University of Technology, electrochemical sensors developed alongside teams at EPFL and TU Munich, and hydrometallurgical processes drawing on expertise from Colorado School of Mines and University of Toronto. The lab also addresses hydrogen production linked to projects with Siemens, Air Liquide, and Shell, and advanced materials characterization rooted in collaborations with ESRF, CEMES, and CNES-affiliated groups.

Facilities and Equipment

L2E houses instrumentation for electroanalytical techniques comparable to setups at Max Planck Institute for Chemical Energy Conversion and Argonne National Laboratory: potentiostats and galvanostats from Metrohm and BioLogic, gloveboxes and dry rooms akin to those at Panasonic and LG Chem, and calorimetry units used by researchers at University of California, Berkeley. Analytical resources include scanning electron microscopes similar to JEOL instruments found at Oak Ridge National Laboratory, X-ray diffraction comparable to facilities at Diamond Light Source, and spectroscopy equipment used by groups at Sincrotrone Trieste and Paul Scherrer Institute. Pilot-scale cells and smelting simulators enable scale-up studies referencing practices at Rio Tinto and Alcoa.

Collaborations and Partnerships

L2E maintains partnerships with industrial actors such as Renault, TotalEnergies, ArcelorMittal, and Solvay, and academic exchanges with Université de Lyon, Sorbonne University, and Technical University of Denmark. It participates in European consortia alongside CNRS units, CEA, Fraunhofer Society, and INL, and contributes to networks including EUROBAT, ENERGIC-OD, and EERA. International links extend to collaborations with Toyota Research Institute, Samsung Advanced Institute of Technology, and BASF, and joint projects with national agencies like ADEME and Bpifrance.

Education and Training

The laboratory supervises doctoral candidates enrolled at Université Grenoble Alpes, Grenoble INP, and Institut Polytechnique de Grenoble, and hosts postdoctoral researchers from institutions such as University of Pennsylvania, Kyoto University, and Peking University. L2E offers master-level courses coordinated with ENSAM and École Polytechnique, and provides internships and technical training in partnership with CNAM and CRTC. Outreach activities include summer schools modeled on programs at École Normale Supérieure, participation in Marie Skłodowska-Curie Actions, and professional development workshops for engineers from Alstom and Bouygues.

Notable Projects and Contributions

Noteworthy projects include advancement of lithium-sulfur cell prototypes developed in collaboration with Saft and Thales, electrorefining methods applied in partnership with Rio Tinto and Eramet, and corrosion mitigation strategies implemented with Naval Group and PSA. The laboratory contributed to standardization efforts alongside AFNOR and ISO committees, co-authored reports with IEA and EIT InnoEnergy, and filed patents in coordination with European Patent Office practices. Peer-reviewed outputs have appeared in journals such as Nature Energy, Journal of The Electrochemical Society, and Electrochimica Acta and have been cited by research from Harvard University, Caltech, and Imperial College.
