Super Capacitor Manufacturing Process

After wetting, place the rubber seal on the lead and insert the element into the housing.

Heat shrink the sleeve printed with rated voltage, capacity, characteristics, etc. onto the capacitor.

Apply the rated voltage to age (combine) the component.

100% of units undergo electrical testing and visual inspection for troubleshooting.

Coin Super Capacitor Manufacturing Process

Select suitable electrode materials, typically activated carbon, carbon nanotubes, etc., for the preparation of the electrode sheet.Use methods such as chemical deposition or electrochemical deposition to ensure an even distribution of electrode materials on the sheet.

Supercapacitor

Utilize mechanical or laser equipment to create holes in the electrode sheet. The design of these holes aims to increase the surface area of the electrode, enhancing the performance of the supercapacitor.

Supercapacitor

Perform adhesion treatment to ensure the stability and adhesiveness of the electrode sheet. This may involve coating the surface of the electrode sheet with an adhesive to improve its attachment to other components.

Supercapacitor

Introduce an appropriate electrolyte, typically a liquid electrolyte, into the supercapacitor to form a charge storage layer and facilitate charge conduction between positive and negative electrodes.

Assemble the electrode sheet and electrolyte layer according to the design and seal them together, ensuring the encapsulation of the internal environment of the supercapacitor.
