Electrode & Membrane

Flow battery typically uses porous graphite felt based on polyacrylo nitrile(PAN) precursors as the electrode.The electrode serves as reaction interface for the oxidation-reduction reactions of the electrolytes.ZH Energy has developed a process to load catalyst particles onto graphite felt electrodes firmly,enabling us to offer customized graphite felt electrodes with catalysts for various flow battery techniques.
