Problems solved by technology

These issues include: capacity improvement, equivalent series internal resistance reduction, cycle life increase, electrode material / electrolyte compatibility issues, etc.
At present, some supercapacitor manufacturers do not have enough control over the assembly process, resulting in poor performance of the final supercapacitor product and a wide distribution of performance parameters.

Abstract

The invention relates to a high performance super capacitor and a manufacturing process thereof. The super capacitor comprises an electrode core, an electrolyte and a shell. The manufacturing process comprises steps that: tabs and leading-out terminals of the prepared electrode core positive and negative poles are welded; the electrode core with the well-welded leading-out terminals is encased in the shell; the shell with the electrode core encased is put in a vacuum drying furnace for vacuum drying; and finally a vacuum liquid filling sealing test is carried out. In an aspect of the electrode manufacturing method, the manufacturing process of the invention abandons a method which uses a solvent for assisted processing, thus to the greatest degree, the purity of the electrode material is ensured. In addition, during the production process, the manufacturing process of the invention has no drying energy waste and drying time constraint, and therefore reduces cost, reduces energy loss, and improves working speed. The manufacturing process of the invention further adopts an advanced assembly process to avoid problems such as secondary pollution and processing consistency in the traditional assembly technology, and greatly improves the stability of the super capacitor.

Description

technical field [0001] The invention relates to a high-performance supercapacitor and its manufacturing process. Background technique [0002] Supercapacitors, also known as electric double layer capacitors and gold capacitors, have a capacity more than 1000 times that of traditional capacitors. Compared with lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, lithium-ion batteries and other batteries, it has higher power density and lower equivalent series internal resistance. Therefore, supercapacitor is a new type of energy storage element with both capacitance and battery characteristics. Because supercapacitors have the advantages of small size, good safety, light weight, high specific energy, high specific power, long life, and no pollution, etc., it has been used in wind power generation, solar power generation, hybrid vehicles, UPS, subway, electrode, robot automation and other application fields. In recent years, the basic research and ...
