What is RS2E?

Researches explained

  • 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.
