METAL OXIDE SUPERCAPACITOR HAVING METAL OXIDE ELECTRODE COATED ONTO THE TITANIUM DIOXIDE ULTRAFINE AND ITS FABRICATION METHOD
摘要
<p>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.</p>
