The prize is a recognition for his work dealing with the development of high performance supercapacitors for low temperature applications, which is an important advance in the fields of aeronautic or aerospace industry among others. The promising results obtained in this project, in a tight collaboration with an industrial partner (IOLITEC, Ionic Liquids Technologies GmbH, Germany), have demonstrated the enormous potential of innovative ionic liquid-based electrolytes to take up such challenges. Consequently, graphene supercapacitors were able to operate at extreme working temperatures (down to -60°C) maintaining an excellent electrochemical response in terms of energy, power density as well as an extraordinary lifetime.
