Un stockage d’énergie rapide et performant grâce au nitrure de ruthénium

Prized for their power, rapid charge and long life, supercapacitors are a great complement to batteries. An international team organised around the CNRS, the Soleil synchrotron and several universities has developed electrodes based on ruthenium nitride, with exceptional performance. Published in Nature MaterialsThis work also includes methodological developments for studying the electrochemical processes at work in supercapacitors.
