Preparation and surface modification of PVDF-carbon felt composite bipolar plates
However, owing to brittleness of graphite, graphite bipolar plates are unyielding and it is difficult to prepare bipolar plates over large areas (e.g., a length and width of ∼600 mm) [10]. Unlike fuel cells, vanadium flow batteries provide low current densities, typically below 150 mA/cm 2, because of slow mass transport and charge
