The application of felt electrodes is outlined on the example of the vanadium redox flow battery (VRFB). Then, the interrelation of carbon felt and carbon fiber is explained regarding the manufacturing process of carbon felts and a selection of suitable starting materials.
Permeable electrodes made of SIGRACELL carbon and graphite felts are the first choice for high-temperature batteries like redox flow batteries. Our felts are used for anodes as well as cathodes.
The cost assessment of carbon felt electrodes is carried out in accordance with the system modules described in Fig. 2. Thus, total costs are defined as the sum of costs of the white fiber, the textile processing and the carbonization process.
PAN-based carbon and graphite felts are used as electrode backings in a variety of battery designs including vanadium redox flow batteries (VRB). The high conductivity, high purity, and chemical resistance of felts make them ideal for the demanding design criteria of flow battery developers.
Only very few manufacturers of carbon felts, such as SGL Carbon SE, a world market leader in carbon materials, offer specialized carbon felt electrodes for electrochemical applications. The requirements for felt electrodes are different from those for insulation or mechanical applications.
Carbon felt electrodes are made from PAN or viscose fibers . These three materials are described below supplemented with the biomaterial lignin, which is a promising object of research. PAN is the dominating precursor for carbon fibers, containing 68% carbon. It was first recognized as a suitable starting material in 1961 .
