Dr. Marine Reynaud has focused her research on the development of new electrode materials for Li-ion and Na-ion batteries for the last 10 years. She has extensive experience in inorganic syntheses and a wide knowledge in materials characterizations, including X-ray and Neutron powder diffraction, electron microscopy, solid-state NMR and Mössbauer spectroscopies, as well as electrochemical techniques. She is in particular expert in structure determination and microstructural characterization of layered and polyanionic compounds. She holds a French "Diplôme d'Ingénieur" in Chemical Sciences and Engineering from Chimie ParisTech and a Master in Chemistry "Paris Centre” with a major in Materials and Energy (UPMC-ENSCP, Paris, France). In 2013, she completed her Ph.D. in Material Sciences (cum laude) focused on the preparation of new bimetallic sulfates for high-voltage electrode materials for Li- and Na-ion batteries and conducted under the supervision of Prof Jean-Marie Tarascon, Dr. Jean-Noël Chotard (UPJV, Amiens, France) and Dr. Gwenaëlle Rousse (UPMC, Paris, France). Dr. Reynaud joined in 2014 the group of Dr. Montse Casas-Cabanas at CIC energiGUNE as a postdoctoral fellow, before she got her Associate Researcher position in 2018. At CICe, she has kept developing new polyanionic electrode materials for Li- and Na-ion batteries, while she has focused another part of her research on the characterization of materials with microstructural defects (e.g. stacking faults in layered materials). She has in particular collaborated in the development of the program FAULTS for the refinement powder diffraction data of defective structures (open software released in 2015 within the FullProf Suite). For the last three years, she has been working on innovative strategies to accelerate the discovery of new battery materials. During her research career, she has been involved in several industrial projects (e.g. CEGASA, UMICORE) as well as competitive regional, national and European research projects (e.g. ION-STORE, 3beLiEVe), and she has supervised 12+ undergraduate, Master and PhD students.
