Keywords : Transition metal lamellar oxides and phosphates, Li-ion or Na-ion batteries, Mechanisms, Structure-properties relationship, Solid State NMR, Fermi Contact shifts, DFT calculations.
My scientific activities concern intercalation materials as layered transition metal layered oxides and phosphates able to act as positive electrodes in a Li-ion or Na-ion batteries. The mains goals of my activities are to better understand the structures and the electronic structures of the materials (lithium/sodium sites, ordering, defects …) in relation with their electrochemical and their physical properties and the intercalation/deintercalation mechanisms of the alkaline ions (structural changes, redox mechanisms, diffusion…). These aspects are the key points that should lead to an optimization of the materials performances or to the finding of new materials.
My research activities can be split into two main parts :
i) Positive electrode materials : synthesis, electrochemical properties, mechanisms
ii) NMR study of paramagnetic materials
Solid state Nuclear Magnetic Resonance (NMR) is a powerful tool to investigate the Li nucleus (or other nuclei as 23Na, 59Co, 31P, 1H) local environment in intercalation electrode materials for Li-ion or Na-ion battery application. As most of the materials are paramagnetic, their NMR spectra are consequently dominated by interactions between nuclear and electron spins (hyperfine interactions). Progress in the understanding of these interactions involves the analysis of local geometries and their suitability for electron spin transfers based either on delocalization or polarization-type mechanisms leading to positive or negative Fermi contact shifts, respectively. This effort is greatly supported by calculation strategies. I have been developping the use of DFT calculations (suitable for inorganic periodic materials) for some years with two main aims :
i) assign the different MAS NMR signals in paramagnetic phases
ii) understand the spin transfer mechanisms from the transition metal ions to the different adjacent nuclei.
