The ultra-thin carbon fiber felt is made of PAN based carbon fiber as the substrate, through a special needle punching process and high-temperature treatment. This type of felt has low resistance and good hydrophilicity, making it very suitable for fields with high requirements for resistance and reactivity, such as liquid flow batteries.
Note that this type of felt is completely different from the carbon felt used in the insulation field on the market. Compared to carbon felt in the field of insulation, this felt has better fiber toughness and is less prone to powder shedding. At the same time, there are also differences in production processes.
Material characteristics : ◆ The felt body is very soft and can be made into flexible electrode materials
◆ High chemical activity, good liquid wettability, promoting rapid redox reactions
◆ High porosity and low resistivity
