Zusammenfassung:A poly(acrylonitrile)(PAN) textile including plural PAN fibers is provided first. The diameter of the PAN fibers is from about 50 nm to about 500 nm. Then, a heat treatment of the PAN fiber textile is carried out to form a carbon fiber textile. The carbon fiber textile includes plural carbon fibers. The diameter of the carbon fibers is from about 50 nm to about 500 nm. Plural nano-size holes are located on a surface of the carbon fibers. The total surface area of the nano-size holes is about 85 to 95 % of total surface area of the carbon fibers. Finally, the carbon fiber textile is further fabricated to form the electrode of the supercapacitor.
