Embodiment 1

[0021] A production process for a high-voltage super-farad capacitor, comprising the following steps:

[0022] (1), material selection: choose aluminum foil as the base material, corrode the surface of the aluminum foil to expand the surface area of ​​the aluminum foil;

[0023] (2), thermal spraying: choose high dielectric constant nanoscale material as one or more of titanium, titanium oxide and barium titanate, tin, zirconium, zinc, and the mesh number of high dielectric constant nanoscale material is not more than 100 nanometers, high dielectric constant nano-scale materials are formed into micron-scale nano-agglomerates by ball milling, and then thermally melted at 4500-5500 ° C and then evenly coated on the surface of aluminum foil by the plasma gun of the plasma spraying equipment. A stable 5-10μm composite dielectric layer is formed on the surface of the surface;

[0024] (3) Electrochemical treatment: place the aluminum foil in a 3-15% aqueous solution of inorganic o...

Abstract

The invention discloses a production process of a high-voltage super Farad capacitor, comprising (1), material selection; (2), thermal spraying; (3), electrochemical treatment; (4), capacitor preparation. The present invention realizes a supercapacitor with a capacitor capacity of 0.47-100F under the condition of 100-800V. Since the above-mentioned requirements can be realized, its application will be extremely wide, especially for wind power, photoelectric energy storage, new energy vehicle power and laser weapons, It is of great significance for high-power military equipment such as particle beam weapons, submarines, and aerospace.

Description

technical field [0001] The invention belongs to the field of energy storage devices, and in particular relates to a production process of a high-voltage super-farad capacitor. Background technique [0002] Supercapacitor is a new type of energy storage device that has been developed rapidly in recent years. It has a large capacity of Farad (F), which is 2000-6000 times larger than that of an electrolytic capacitor with the same volume, and its power density is 10-100 times higher than that of a battery. times, high charge and discharge efficiency, and the number of charge and discharge cycles is as high as 10 5 More times, commercial supercapacitors currently on the market generally include double-layer capacitors, pseudocapacitors, dielectric supercapacitors, etc., with a capacity of 0.47-3000F, but their voltage is generally only 1.2-5.5V. In practical applications, series capacitor modules are often used to increase the output voltage. For example, in the power use of n...
