Jean-François COLIN

Dr. Hab.​

Fellow​

Jean-François Colin has been researching and characterizing new materials for lithium-ion batteries for more than two decades.

He obtained a PhD in Materials Chemistry from the University of Caen Basse-Normandie in 2007, with a focus on the development of oxides for lithium-ion system anodes. He then went on to the Paul Scherrer Institute in Switzerland for a postdoctorate (2008 to 2010) on the synthesis and testing of Li-rich cathodes, which included setting up in situ battery characterization protocols.

He has been a research engineer at the CEA since 2010, developing new materials for lithium-ion batteries, including Li-rich cathodes, high-potential anodes, and solid sulfur electrolytes. He has also developed multiscale operando characterization techniques.

In 2020, he obtained his accreditation to supervise research (Habilitation à Diriger des Recherches, or HDR). Today, his research contributes significantly to the development of energy storage technologies essential for the energy transition.
