Abstract

The invention belongs to the technical field of capacitors and discloses a graphene capacitor. The graphene capacitor comprises a shell; two microporous ceramic matrixes are arranged in the shell; micropores in the microporous ceramic matrixes are filled with graphene particles; a plurality of dielectric through holes are formed between the top surface and the bottom surface of each microporous ceramic matrix; insulating coatings are arranged on the outer side surfaces and the bottom surfaces of the microporous ceramic matrixes; and graphene coatings are arranged on the inner walls of the dielectric through holes and the top surfaces of the microporous ceramic matrixes; one side surface of each of the two microporous ceramic matrixes is fixedly connected in an attached manner; dielectric cavities are formed in the attached side surfaces of the microporous ceramic matrixes; the graphene coatings are arranged on the inner walls of the dielectric cavities; dielectric partition plates arearranged at the opening ends of the two dielectric cavities; and the dielectric cavities and the dielectric holes are filled with electrolyte; and a positive plate is fixed on the top surface of one microporous ceramic matrix, and a negative plate is fixed on the top surface of the other microporous ceramic matrix. The graphene capacitor has the advantages of high charging and discharging efficiency.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a graphene capacitor. Background technique [0002] Graphene capacitors are a general term for supercapacitors based on graphene materials. Due to the unique two-dimensional structure and excellent physical properties of graphene, such as graphene has an ultra-high surface area and super conductive properties, graphene materials can be used in the field of supercapacitors It has great application prospect. However, most of the current graphene capacitors have unreasonable structures, and the excellent physical properties of graphene have not been fully utilized. The current common graphene capacitors still have the problem of low charge and discharge efficiency. Contents of the invention [0003] In order to solve the problem of low charging and discharging efficiency of graphene capacitors in the prior art, the present invention provides a graphene capacitor with high char...
