- Aqueous/nonaqueous/solid electrolytes
The research activity in BATTion group focuses on the synthesis and characterization of new positive and negative materials for lithium-ion batteries and next generation metal-ion batteries (Na, K, Zn-ion…). We provide a comprehensive view of the reaction mechanisms in electrode materials using a kinetic and thermodynamic approach with a particular interest on the electrochemical performance (energy density, cycle life,…) and structural changes (using ex situ/operando XRD and Raman spectroscopy) occurring in the electrode materials under operation. Both basic and applied research is carried out to develop new environmentally compatible and high performance systems (aqueous batteries, solid-state batteries).
