摘要:
An energy storage device including an active electrolyte, a first electrode and a second electrode is provided. The active electrolyte contains protons and ion pairs with a redox ability. The first electrode and the second electrode coexist in the active electrolyte and are separated from each other. The first electrode and the second electrode respectively include an active material producing a redox-reaction with the active electrolyte or an active material producing ion adsorption/desorption with the active electrolyte. The active electrolyte receives electrons from the first electrode and/or the second electrode so as to perform a redox-reaction for charge storage.
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.
