Can carbon felt electrodes be used in redox flow batteries?
6. Conclusions In this study, a commercially available carbon felt electrode designed for use in redox flow batteries by SGL has been investigated for the impact of compression on the electrical resistivity, and the single-phase and multi-phase fluid flow.
What is the electrical resistivity of carbon felt?
Gonzales-Garcia et al. also presented their measurements of electrical resistivity of carbon felt materials, which was in the range of 10–16.3 mΩ m. In comparison, the results presented in this work, demonstrate the electrical resistivity of GFA6 ranges between 8–10 mΩ m and changes as a function of compression.
What is a carbon felt electrode?
A critical component of the RFBs is the carbon felt electrodes which provide the surface area for the reaction to occur. The structure of these electrodes is crucial to the operation as it defines the ease of flow of the electrolyte through the electrode, electrical conductivity, and structural stability .
Are carbon felt electrodes a good choice for large-scale energy storage?
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.
Do carbon felt electrodes improve the performance of RFBS?
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.
Why is carbon felt a good battery material?
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.
