Flow Battery Felt

Flow Battery Felt

Our company uses imported high-quality polyacrylonitrile fibers as raw materials. Through our independently developed continuous production line, the product has good thickness uniformity, high electrochemical performance, and stable corrosion resistance. It can effectively reduce the internal resistance of the battery stack, improve energy conversion efficiency, increase the current density of the flow battery, and improve the utilization rate of electrolyte. The product is mainly used as electrodes in various flow battery industries.
