Our research activities

Operation 1 : Electrochemical Storage and Conversion of energy


Participants : C. Debiemme-Chouvy, L. Fillaud, A. Pailleret, H. Perrot

Goal : Understand the electrochemical mechanisms related to transfer, transport, and/or adsorption of charges at interfaces and in the bulk of ion exchanger electroactive materials (transition metal oxides, conducting polymers, ...) or capacitive materials (carbon materials)

Main tools : production of thin films using electrochemcial methods, ac-electrogravimetry, electrochemical AFM (EC-(AFM)

Collaborations : CEA Grenoble, LCMCP-SU, CIRIMAT-Paul Sabatier, Collège de France, LPPI-Cergy, LSPM-Sorbonne Paris Nord
