Daisy@foam-material.comHigh-Performance PAN-Based Carbon and Graphite Felts for Vanadium Redox Flow Batteries (VRB)
Introduction
G100 and G200 are the most popular graphite felts used due to their higher purity. They are also less chemically reactive and have higher conductivity (thermal and electrical).
PAN-based soft graphite felts are effective insulating materials for application temperatures up to 2000°C in inert or vacuum atmosphere.
PAN-based carbon and graphite felts are used as electrode backings in a variety of battery designs including vanadium redox flow batteries.
