AI Technical Summary

Problems solved by technology

However, the cost of forming a metal coating on the end face of activated carbon fibers is extremely high, not only the process is very complicated, specific professional equipment (such as PVD equipment, CVD equipment) is required, and the cost is very high

Therefore, the use of the above methods severely limits the production capacity of regenerated activated carbon fibers, and also severely limits the application fields and directions due to the high cost.
