Main Research Activities
Recent developments in in-situ liquid TEM opened a new area in the understanding of interface mechanisms during electrochemical cycling of Li-ion batteries such as the kinetics of lithiation, formation of SEI layer, structural accommodation, crystalline transformation and morphological evolution. The goal of this project is to further identify and study phenomena involved in batteries’ efficiency decay, which is mainly related to induced effects of exchange dynamics at electrode/electrolyte interfaces. Thus, he focus on the study of the mechanism of formation of the SEI layer during the first EC cycles and on the electrolyte’s evolution with different analytical TEM techniques in liquid medium.Surface modification of LiFePO4 nanoparticles through an organic/inorganic hybrid approach and its impact on electrochemical properties
