LEPMI (Laboratoire d’Electrochimie et de Physico-chimie des Matériaux et des Interfaces) is a joint research unit composed by researchers from Centre National de la Recherche Scientifique (CNRS), Institut National Polytechnique de Grenoble (Grenoble-INP), Université Grenoble Alpes (UGA) and Université Savoie Mont-Blanc (USMB).

The main research activities of CNRS-LEPMI deal with the elaborations, physical and electrochemical characterizations of functional materials (polymers, salts, ionic liquids, catalysts, ceramics) intended to be used in electrochemical energy systems.

The team Materials Interfaces and Electrochemistry (MIEL) has a core activity in spectroscopic characterization by Raman and NMR as well as in the designing and electrochemical characterization of polymer electrolytes, salts, ionic liquids and ionomers dedicated to energy sources (lithium-polymer, lithium-ion, lithium sulfur, Mg, Na batteries, and polymer fuel cells (protonic and alkaline conducting membranes). Additionally, the team has a large activity in the study of relation structure/properties by using coupled investigation such as: Electrochemistry/Raman, Electrochemistry/NMR in situ and operando.

Data of involved researchers:

Dr. Cristina IOJOIU is a CNRS senior scientist since 2006. She has worked for 17 years in the synthesis, characterization and degradation of electrolytes for electrochemical devices (PEMFC, Lithium batteries) based on polymers and ionic liquids. Dr. Iojoiu is the Leader of the scientific project “multifunctional materials for electrochemical generators” of Labex CEMAM. She supervises as a scientific coordinator of an international collaborative project (ANR-NSERG 2016-2019), a Rhône-Alpes project (POLIH) on nano-structured polymer electrolytes for energy conversion. She was coordinator of LEPMI partner of three ANR projects (EuBECELL, SLIM, CLIPPAC), one FEDER –FUI (NMHT), two European projects (ITN-FlowCamp, FETOPEN – VIDICAT), these projects dealing with polymer electrolytes for lithium and post lithium batteries, Proton Exchange Membrane Fuel Cells (PEMFC) and redox flow Batteries. She published 75 peer-reviewed papers and 5 book chapters; she has an h-index of 21/23 (Scopus/ Google Scholar). She delivered 17 invited lectures and is co-inventor of 15 patents dealing with electrochemical energy sources, most of which are extended patents. She has supervised 15 PhD students.

Dr. Fannie ALLOIN received her PhD degree from the University of Grenoble, France, in 1993.and she is senior researcher (CNRS) at LEPMI since 1995. She is the leader of team Materials Interfaces and Electrochemistry from LEPMI. Furthermore, she belongs to the elected steering committee of CNRS, pole PEM (Physic, Engineering and Material) COMUE-UGA and HDR I-MEP2 and UGA doctoral school I-MEP2. She was scientific coordinator of LEPMI partner in 5 ANR and one ADEME projects and coordinator of different regional projects. Her research has ranged over energy conversion, especially for lithium electrolytes (liquid electrolyte, ionic liquid, polymer electrolyte) and electrochemistry of the interface for lithium battery, lithium/sulfur and supercapacitor applications. She has published more than 111 peer-reviewed papers and 5 book chapters. Moreover, she has an h-index of 33. She is co-inventor of 22 patents dealing with lithium battery. She has been main supervisor for 18 PhD students

Dr. Nicolas SERGENT (male) is Associate Professor at CNRS-LEPMI employed by Grenoble INP Institute of Engineering. He has a strong experience in IR and Raman spectroscopies to study the interactions (adsorption and/or reaction) of molecules on materials surface. More generally, his research activity mainly concerns the chemistry of materials and phase transitions, characterization of nanomaterials and nanodevices, and surface reactions. He has contributed to 1 European project and 2 ANR projects. He has published 25 peer-reviewed papers and has been supervisor for 4 PhD students.
