Descriptif des activités de recherche

The PhD thesis concerned aims to develop a comprehensive understanding of the working principles of All Solid State Batteries (ASSBs) by creating and experimentally validating a 3D computational model that accounts electrochemical reactions, ionic and electronic transport and Mechanics during charge and discharges cycles. The model should allow providing guidelines for the microstructure optimization in terms of mechanical stability.
