Spectroscopical characterization of electroactive interfaces for innovative batteries Line of research The surface reactivity of innovative nanostructured materials (carbonaceous, transition metal oxides), which can be used as electrodes in batteries, is studied through photoemission/photoabsorption spectroscopy of both core (XPS) and valence (UPS) levels, and with traditional and synchrotron sources. The sensitivity of these techniques allows a fine analysis of the variations of the oxidation state and of the chemical environment of the chemical species involved in the electrode processes.
