Technical FAQs 4

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.

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.

Can carbon felt be used in all soluble flow batteries?

Over the past decade, tremendous effort has been made to modify carbon felts for a better use in all-vanadium and other types of all-soluble flow batteries, these typically including heteroatom doping and metal catalyst decoration , , , , , , , .

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 .
