    摘要： The present invention discloses an ultrafine graphitic carbon fiber and a preparation method thereof. An ultrafine fiber having a diameter of 1 to 3000 nm is prepared by electrospinning a halogenated polymer solution containing a metal compound inducing graphitization. In carbonization, an ultrafine porous graphitic carbon fiber having a large specific surface area, micropores and macropores is prepared by the graphitization by a metal catalyst generated from the metal compound. The ultrafine carbon fiber can be used as a carbon material for storing hydrogen, an adsorbing material of biochemically noxious substances, an electrode material of a supercapacitor, a secondary cell and a fuel cell, and a catalyst carrier material.

    摘要： A supercapacitor having a metal oxide electrode and a method for preparing the same. The method comprises preparing a substrate composed of a current collector and a titanium dioxide ultrafine fiber matrix layer formed on the current collector, and electrochemically depositing a metal oxide thin film layer onto the substrate by a constant current potentiometry or a cyclic voltammetric method. Since the metal oxide is uniformly deposited on the substrate having a wide specific surface area with the titanium dioxide ultrafine fiber, a bonding material or a conductive particle need not to be added to the capacitor electrode. Therefore, a resistance of the capacitor electrode is prevented from being increased, and thus a capacitance of the capacitor electrode is prevented from being decreased.
