How Coiled Electric Double-layer Capacitors(DZ Series) Are Manufactured

Activated charcoal and binders are mixed and formed into a sheet.
Disks with specific diameters are punched out of the electrode sheet.
A conductive adhesive is used to adhere the electrodes punched from the sheet to the metal case and cap that will form the capacitor.
After drying, the case and cap (with the electrodes glued inside) are filled with an organic liquid electrolyte inside a dry box.
The case and cap are assembled together with a separator and a gasket, and the case is crimped in a case to seal the opening, forming a coin cell.
100% of the coin cells are subjected to electrical testing.
Because the withstand voltage of the individual coin cells is between 2.8 and 3.0 V, two or three of these cells are connected in series.
