Resistivity of carbon felt for flow batteries

4 FAQs about [Resistivity of carbon felt for flow batteries]

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.

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.

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 .
