Electrode for electrolytic capacitor

摘要

An electrode for an electrolytic capacitor is disclosed, including a substrate and a metal oxide formed on the surface of the substrate, wherein the metal oxide is formed on the surface of the substrate by a chemical reaction between a precursor and functional groups on the surface of the substrate. The surface of the substrate is covered with a metal oxide for increasing the capacitance of the electrode. The metal oxide-covered substrate is suitable for being used as an electrode of an electrolytic capacitor in that the metal oxide formed on the surface of the substrate by chemical linking is of excellent peeling resistance.
