Self‐Sustained Thin Webs Consisting of Porous Carbon Nanofibers for Supercapacitors via the Electrospinning of Polyacrylonitrile Solutions Containing Zinc Chloride

Currently, intrinsicproblems, such as their limited available amount of chargeand high cost, combined with their low effective specific sur-face areas, limit the practical usage of carbon nanotubes asthe electrode material in supercapacitors.Recently, we reported another route to fibrous carbon ma-terials (ca. 300 nm) that relies on an electrospinning step withsubsequent steam activation.
