It features excellent thickness uniformity, low stack internal resistance, good electrochemical performance, strong corrosion resistance, low stack cycling degradation, and high energy efficiency. Made from high-quality polyacrylonitrile-based fibers through non-woven and needle-punching processes to form a felt, and then produced via pre-oxidation, carbonization, and graphitization processes, it is a carbon fiber felt with extremely high requirements for flatness, porosity, bulk density, specific surface area, and electrical conductivity. It is primarily used in flow energy storage battery systems.
