This product is a special graphite felt electrode material for all vanadium flow battery electrode. It is made of imported oxide wire needle felt through carbonization, graphitization and other processes,Because the production process of the product is processed and produced by continuous equipment, the felt surface is flat, the thickness is uniform, and the electrochemical performance is consistent everywhere. It is used in the electrode material of all vanadium liquid flow battery. It has the characteristics of small internal resistance of the stack, good and uniform electrochemical activity, good corrosion resistance, low cycle attenuation of the stack, high energy efficiency and so on.
