Product Introduction
This product is a graphite felt electrode material for all vanadium flow batteries, made from specially treated carbonizable fibers through processes such as needle punching, carbonization, and graphitization. The felt body of the product is flat, with uniform thickness and consistent electrochemical performance in all parts. When used in all vanadium flow battery materials, it has good electrochemical performance, corrosion resistance, low cycling attenuation, and high energy efficiency.
Porous electrodes made from carbon & graphite felt. Battery Felts are used in advanced batteries such as flow batteries and Fuel cell. Combines excellent chemical resistance and inertness properties with high porosity and good electrical conductivity.
