DescriptionGFE-1 Graphite FeltPre-fired / Heat-treated Temp: 3992℉ | 2200℃Grade: Flow Battery Felt (VRFB)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.Flow Battery DiagramBenefitsProprietary activation process increases active sites and surface area to over 1000 M²/gSpecialized felt weave results in a smoother surface and a more homogeneous structure for more stable and consistent electrical performanceCustom run material that can be optimized for your specific applicationDeveloped specifically for the demanding needs of flow battery applicationsApplicationsVanadium redox flow batteries (VRFB)Fuel Cell and Flow Battery electrodesIron flow cellsHeated filamentsSensor TechnologyPropertiesPropertiesUnitValuesNoteThicknessmm1-16Made to orderThickness Tolerance%± 10MaxWidthm1 - 1.4Made to orderLengthm≥ 40Made to orderCut to Size Tolerancemm± 1.5MaxDensityg/cc0.06 - 0.13Made to orderDensity Tolerance%± 10MaxElectrical ResistanceΩ-cm0.275MaxCarbon Content%99.8MinVanadium Liquid Adsorption (2 mol/L)g/g17MinDropping Crumbs%0.168MaxAsh ContentPPM500MaxMetal ContentPPM300MaxIron ContentPPM30MaxDocuments Technical Data Sheet Safety Data Sheet
