Abstract:
1. A method for manufacturing an electrode of a supercapacitor, comprising: providing a poly(acrylonitrile) fabric, the poly(acrylonitrile) fabric comprising a plurality of poly(acrylonitrile) fibers each having a diameter of about 50-500 nm; heat treating the poly(acrylonitrile) fabric to form a carbon fiber fabric comprising a plurality of carbon fibers each having a diameter of about 50-500 nm, wherein a surface of each of the carbon fibers has a plurality of nano pores of about 1-50 nm in diameter, and a total surface area of the nano pores accounts for about 85-95% of a total surface area of the carbon fibers; and cutting the carbon fiber fabric to acquire the electrode.
