An international team, bringing together several RS2E laboratories, demonstrates in an article published in Nature Communications that it is possible to couple a solid lamellar catalyst to an alkaline electrolyte to avoid destabilization
An international team led by Prof. Jean-Marie Tarascon, RS2E director, had the idea of subjecting a so-called "Li-rich" electrode material to harsh oxidation and reduction conditions to better understand its changes in structure and composition
Significant pseudocapacitive properties and ease of large-scale production. Vanadium nitride films have all the qualities required to pave the way for mass production of energy storage micro-devices capable of powering the Internet of Things of tomorrow.
A team of researchers has developed strategies to destabilize inactive systems and create new performing and robust catalyzers for water electrocatalysis

For 7 years, RS2E researchers have been publishing several papers on the phenomenon of anionic redox. This oxidation-reduction phenomenon is added to the “classical” cationic redox, in particular in the “Li-rich” materials and leads theoretically to higher energy density batteries. Their lifetime could be increaded by 20%.
