Graphite Felt for Flow Battery Electrodes

Which electrodes are used in flow batteries?

Currently, carbon-based porous electrodes, commonly graphite felt (GF), carbon felt (CF), carbon cloth (CC), and carbon paper (CP), are extensively employed in flow batteries due to its advantageous stability, excellent electrical conductivity, and superior corrosion resistance .

How is graphite felt used in electrochemical workstation?

Then, the pure lead and graphite felt are put into the electrodeposition solution to act as positive electrode and negative electrode separately, which are both connected with the electrochemical workstation. During charging process, the positive pure lead is oxidized to ions and dissolved into the electrodeposition solution.

Is graphite felt a disadvantage of redox flow batteries?

J. Alloy. Compd., 891 ( 2022), Article 161983 A novel cell design of vanadium redox flow batteries for enhancing energy and power performance Graphite felt is disadvantageous of lower electrochemical reaction activity, which is improved by introducing catalysts.

Can redox flow cells improve the electrochemical activity of graphite felt?

In this work, thermal, chemical and plasma treatments have been employed to modify the surface of the graphite felt to improve the electrochemical activity of the redox flow cell. The influence of the variables of each of these processes on the generation of surface functional groups and on changes in the obtained surface area have been examined.
