Whereas batteries provide energy over several hours, supercapacitors deliver energy peaks in seconds, and provide strong power. Balancing energy and power under constrained volumes is the key challenge for the growth of many industrial applications including the electric vehicle where autonomy and speed have to be merged as well as the field of mobile (charging time and power of flash a mobile phone) and of micro-electronics.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
