Abstract

The invention discloses a cathode blanked non-inert anode super pseudo-capacitor. The capacitor comprises a housing, wherein a body is positioned in the housing, an anode current collector is positioned in the body; the inner side of the anode current collector is coated with an amorphous silicon layer to form an anode working surface; a porous graphite inversion layer is deposited on the anode working surface; electrolyte is filled between the anode current collector and a cathode current collector in the body; the cathode current collector is positioned in the centre in the body; a wire pressing plate is embedded at the upper end of the body; a sealing head is encapsulated at the upper end of the housing; an aeration radiation plug is arranged on the sealing head; and an anode pile and a cathode pile on the sealing head are respectively connected with the anode current collector and the cathode current collector through the wire pressing plate. The cathode blanked non-inert anode super pseudo-capacitor can more effectively obstruct the hydrated anions and fundamentally avoid anode loss, has the advantages of no anode gassing phenomenon, relatively high output power and relatively low cost and is mainly used as traction power supplies for road vehicles, power supplies for field operation, storage power supplies for renewable energy and various emergency and standby power supplies.

Description

technical field [0001] The present invention relates to a capacitor. Background technique [0002] The known supercapacitors (also known as electric double layer electrolytic capacitors) use the ionization resistance properties of incompatible (inert) anodes to absorb hydrated anions, thereby forming a unique electric double layer on the surface of the anode. This barrier is not based on dielectric isolation, but on the back-to-back affinity of charged particles between positive and negative electric fields, the distance of which is only a few angstroms Therefore, it is equivalent to an equivalent parallel plate capacitor with extremely small pole spacing. Since the anode materials are mostly inert rare and expensive metals with many pores and a large surface area and their oxide ceramics (shape-stable anodes) are even added with activated carbon, the capacitance is extremely large (see "Selection of Electronic Components" Cui Tiren editor-in-chief Zhejiang Science and Tec...
