Professional Perfluorinated Ion-Exchange Membrane(PIEM) and Vanadium Redox Flow Battery manufacturer in China

activated energy storage graphite felt

Product Name: Flow Battery Felt
Product Series: Energy Storage Graphite Felt
Product specifications: thickness (mm) = 3.4-8.0 width (m) = 1.3-1.5 length (m) = 50-100
Scope of application: used for energy storage batteries

The electrodes made of carbon and graphite felts are the first choice for high-temperature batteries like redox flow batteries. Our graphite felts are used for anodes as well as cathodes. Thanks to a unique combination of electrical conductivity, electrochemical stability, high porosity, and good elasticity, they facilitate an efficient charge exchange between the electrolyte and the bipolar plate.

The Advantage description is as follows:

Our graphite felt has uniform thickness, stable electrochemical performance, charge and discharge current density can be increased by more than 2 times, good flatness, low resistance, voltage and energy efficiency can be increased by more than 30%, and energy efficiency is not attenuated during long-term charge and discharge .
