Despite being promising cost-wise, sodium-ion batteries were not able to overpass lithium ones in terms of specific energy until now. To fill the gap, RS2E researchers (Collège de France/LRCS) with the help of Argonne National Laboratory tried to use the Na3V2(PO4)2F3 (or NVPF) electrode at its full potential by harnessing the third sodium which was considered as impossible before. This activation is done via the formation of a disordered material and improves the NVPF electrochemical performances.
Researchers from PHENIX (Paris) and CIRIMAT (Toulouse) published in Physical Review X their works on the use of capacitive technologies to create osmotic energy.
Des chercheurs du RS2E ont publié dans la revue Nature Energy un état des lieux du redox anionique, un phénomène qui pourrait ouvrir la voie vers des batteries plus autonomes et sans cobalt.
A group of researchers from RS2E has studied the impact of electrolyte design on the performance of supercapacitors. Their study was published in November 2016 in Nature Materials.
Two researchers are studying environmental issues and monitoring performance in the context of mass commercialization of rechargeable batteries.
