What is GFE-1 Graphite Felt?
GFE-1 is graphite felt that has been specifically designed and manufactured for the demanding needs of flow battery applications. The material is woven from specialized graphite fibers that are treated with our proprietary activation process to increase active sites and surface area to over 1000+ M²/g. Additionally, the felt weave results in a smoother surface and more homogenous structure for more stable and consistent electrical performance. This ultra-high-quality graphite felt is designed for high wetting and absorption but is optimized for specific applications. This is a a custom production item. Samples and some production rolls are stocked for immediate shipment but our engineering team is always available to help with your next application.
