Battery Materials and Diagnostics Group
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.
Observer des batteries tout solides en train de se déformer
Des chercheurs de l’Institut Paul Scherrer PSI ont observé avec une précision inégalée à ce jour des processus mécaniques qui se passent dans les batteries tout solides. Le recours à la tomographie aux rayons X à la Source de Lumière Suisse SLS leur a permis de découvrir le mode de propagation des fissures à l’intérieur des batteries. Leurs conclusions pourraient permettre d’améliorer la sécurité et la performance des batteries des voitures électriques et des smartphones.

Operando X-ray photoelectron spectroscopy, to monitor the chemical and electronic interface evolution in all-solid-state batteries
Degradation of the solid-electrolyte interface occurring during cycling is currently one of the most challenging issues for the development of all-solid-state batteries. Here we designed a unique electrochemical custom made cell for operando X-ray photoelectron spectroscopy (XPS) capable of maintaining high mechanical pressure with reliable electrochemistry and able to monitor in real-time the surface (electro-)chemical reactivity at the interfaces between the different composite.
