High-capacity super capacitor and method for producing the same

Abstract

The invention discloses a high power super capacitor and preparing method thereof, which belongs to preparing technical range for capacitor. The capacitor is sealed by a serial connection of a plurality of capacitor monomers. An upper pole ear is connected to a top metal basal body, and a lower pole ear is connected to a bottom metal basal body, thus forming a metal oxide super capacitor with certain working voltage. The preparing method comprises the following steps: adopting ruthenium trichloride, iridous chloride, four-butyl metatitanic acid as reaction precursor to attach on a titanium metal basal body; acquiring a multivariant metal oxide active electrode by performing oxide processing for the titanium metal basal body in the conditions of certain temperature and atmosphere; and preparing micro-protruding lattice supporting body on the surface of the electrode as a pole septum. The electrode edge is coated with hot molten glue to form independent chamber between two electrodes. Then, a plurality of electrodes are overlapped in sequence for hot molten serial connection sealing. The prepared novel capacitor has the advantages of small volume, low inner resistance, large discharging power and short response time, which can be widely used in multiple fields.
