Project description

Joanna SEM.JPG

Our goal is to develop novel materials and to improve existing materials for Li-ion, Li-S, and exotic (Na, Mg, Ca, etc...) batteries. We apply different synthetic routes, such as sol-gel chemistry, mechanosynthesis, solid state synthesis under various controlled atmospheres, and microwave synthesis to control the morphology and obtained the most promising electrochemical performances of a dedicated systems. Recently we started to work in all-solid-state batteries with the development of solid electrolytes based on perovskite materials and integrated them into microbatteries using thin films technology in collaboration with Prof. T. Lippert group The Thin Films and Interfaces Group

In the meantime, we elucidate the electrochemical reaction mechanisms of battery systems by applying advanced operando techniques. We have developed many electrochemical cells for the purpose of X-ray diffraction (in house and in synchrotron beamline), neutron diffraction, X-ray absorption, X-ray tomography etc.... Our cells are able to sustain many cycles (not only at room temperature) and then we can gain knowledge in aging mechanisms of battery systems (half-cell or full-cells, lab scale or commercial batteries). We also look at post mortem morphology and aging mechanisms of the cells components by using SEM, STEM, Cross-section devices and FIB/SEM and coupling them with a deep surface analysis using X-ray photoemission spectroscopy in collaboration with Advanced Characterization of Battery Materials .
