Abstract

The invention provides a manufacturing method of a planar comb teeth type super capacitor, and belongs to the technical field of energy storage equipment. The manufacturing method of a planar comb teeth type super capacitor coats a comb teeth type metal copper layer printed on a flexible PCB with mixed slurry of active carbon, conductive agent and binder through screen printing, thus effectively solving the problem that when the active electrode materials are attached to the comb teeth type current collector with small pitch comb of in the pitch, the contact between the two electrode materialsis liable to cause a short circuit, and can precisely control the thickness of the active materials by changing the thickness of the metal mesh used in the screen printing process, thus greatly simplifying the manufacturing process of the planar comb teeth type super capacitor, and significantly improving the consistency of the specification parameters of the mass-produced planar comb teeth typesuper capacitors. The manufacturing method of a planar comb teeth type super capacitor has the advantages of simple manufacturing process, strong operability, low cost, high safety, stable performanceand high product yield, solves the problem that the existing method has a complex process, poor reliability, high cost and the like, and is suitable for industrial applications and market promotion,especially for the field of micro-energy and flexible electronics.

Description

technical field [0001] The invention belongs to the technical field of energy storage equipment, and in particular relates to a production process of a two-dimensional planar thin comb-tooth structure supercapacitor with a screen-mounted mask missing printing as the core and a two-dimensional planar supercapacitor produced by the process. Thin comb structure supercapacitor. Background technique [0002] Supercapacitor (Supercapacitor), also known as Electrochemical Supercapacitor (Electrochemical Supercapacitor), is a new type of energy storage device between traditional capacitors and batteries. It has the characteristics of good performance, green environmental protection and high safety. [0003] Supercapacitors can be divided into two types according to the mechanism of capacitance generation: electric double layer capacitor (Electrochemical double layer capacitor) and pseudo capacitor (Pseudo capacitor). Among them, the capacitance of the electric double layer capacit...
