Abstract

The invention discloses a super capacitor. The thickness of an anode pole piece and the thickness of a cathode pole piece are different, the thickness range of the anode pole piece is 180 micrometers to 280 micrometers, and the thickness range of the cathode pole piece is 160 micrometers to 260 micrometers. The manufacturing process of the super capacitor comprises the steps: (1) material preparation, (2) the preparation of an electrode on a coating device, (3) electrode rolling, (4) the formation of pole pieces, (5) the formation of an electric core, (6) the connection of a leading-out terminal, (7) the vacuum drying of the electrical core, (8) vacuum liquid injection, and (9) safety explosion-proof. After the above structure and manufacturing process are adopted, the volume of the anode pole piece is larger than the volume of the cathode pole piece, the active space of an ion is greatly raised, the factors of electrode corrosion are reduced, the condition that a diaphragm hole is not blocked by an attachment is ensured, and the stability and the service life of the product are raised.

Description

technical field [0001] The invention relates to the field of capacitors, in particular to a super capacitor and a manufacturing process thereof. Background technique [0002] A supercapacitor is an electrochemical component with a very high power density, 10 to 100 times that of a battery, suitable for short-term high power output, fast charging speed, simple mode, and can be charged with a large current. The charging process can be completed within seconds to minutes. The electrochemical reaction that occurs during the charge and discharge process has good reversibility, and the low temperature performance is excellent. This is because most of the charge transfer that occurs during the charge and discharge process of the supercapacitor is carried out on the surface of the electrode active material, and the capacity decay with temperature is very small. , Therefore, supercapacitors have the advantages of high power density, small internal resistance, short charging time and...
