Written by AZoNanoJan 25 2021 In association with Imperial College London, researchers from WMG Energy Innovation Centre at the University of Warwick have identified a new way to improve hybrid flow batteries and their commercial applications. A Binder-Free Horizontal Electrophoretic Deposition (EPD) Process Is Used to Activate Commercial Carbon Paper Electrodes Using Nitrogen-Doped Graphene. Image Credit: WMG, University of Warwick. The novel method can preserve electricity in these hybrid flow batteries for extremely long periods for about one-fifth the cost of present-day technologies, with zero emissions and minimal location limitations. With the help of nitrogen-doped graphene (exposed to nitrogen plasma), the team has successfully improved three hybrid flow cells in a binder-free electrophoresis method (EPD).
