Fast, high-performance energy storage thanks to ruthenium nitride

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