Researchers from the Warwick Manufacturing Group (WMG) at the University of Warwick, together with members from the Imperial College London, has enhanced three hybrid flow cells with the use of nitrogen doped graphene – graphene sheets exposed to nitrogen plasma – using a binder-free electrophoresis (EPD) technique.
The new technique could potentially promote wider acceptance and renewable energy sources – such as hydro and solar power – currently limited by intermittency problems that prevent mass adoption of these sources into larger, national-scale power grids. One idea explored in working around this limitation is the use of long-duration battery technologies, like redox flow batteries. However, despite its longevity and performance, current costs have become significant tradeoff considerations and also hampers widespread adoption.
