They are considered an excellent choice for large-scale energy storage. Carbon felt (CF) electrodes are commonly used as porous electrodes in flow batteries. In vanadium flow batteries, both active materials and discharge products are in a liquid phase, thus leaving no trace on the electrode surface.
The compression of carbon felt electrodes plays a crucial role in enhancing the performance of RFBs because such flow batteries depend heavily on cell resistance during stack assembly. However, compressed carbon felt electrodes are solely based on an increase in cell clamping pressure performed on conventional VRFBs.

Multifunctional Carbon Felt Electrode with N‐Rich Defects Enables a Long‐Cycle Zinc‐Bromine Flow Battery with Ultrahigh Power Density.
Due to the corrosive nature of zinc–iron battery's electrolyte, carbon-based materials are generally implemented. Among them, carbon felt (CF) stands out due to its good electrical conductivity, excellent corrosion resistance, reasonable cost, three-dimensional structure, and wide operating potential 29, 30.
