It is widely used in vanadium redox flow batteries, energy storage systems, fuel cells, and industrial electrochemical applications, ensuring long-term performance in demanding environments.
Product Overview
Flow battery electrode felt is a porous material processed through a series of techniques, including non-woven needle punching, pre-oxidation, carbonization, graphitization, and micro-activation. It is primarily used as the electrode material in flow batteries. This material boasts excellent electrochemical stability, high porosity, and a large surface area, which significantly enhances the electrode reaction rate and charge transfer capability. The electrode felt is not only highly corrosion-resistant but also exhibits excellent adsorption properties, effectively adsorbing and storing active substances from the electrolyte. This improves the energy density and cycling stability of flow batteries. It is widely applied in Vanadium Redox Flow Batteries (VRFB), Zinc-Bromine Flow Batteries, and Zinc-Air Flow Batteries.
