Who we are ?

RS2E - for Réseau sur le stockage électrochimique de l’énergie or "research network on electrochemical energy storage" - is a French research and technology transfer network devoted to energy storage devices: rechargeable batteries, supercapacitors and other alternative techniques intended for multiple commercial products (electric vehicles, portable electronics and electricity storage from renewable sources). RS2E is a CNRS research network (French national center for scientific research) created with the support of the Ministry of higher education and research.

Initiated in 2011, RS2E is coordinated since by Prof. Jean-Marie Tarascon (Collège de France, Paris) and Prof. Patrice Simon (Université Paul Sabatier, Toulouse), two world-class specialists of electrochemical energy storage.

The network benefits from the support of the French government for 10 years under the Investissements d’Avenir program. Eleven of RS2E’s partner research labs were indeed labeled by the French National Agency for Research (ANR) « Laboratoire d'Excellence » (LabEx) back in April 2011.


This label and the corresponding grants allow RS2E to favor a medium-term vision and develop innovative researches to take on the challenge of tomorrow’s batteries.
