ABSTRACT:
The use of water-glass for sticking the ends of the wound foil of an electrolytic foil capacitor comprising a wound assembly of a formed anode foil, a separator and a cathode foil, impregnated with a liquid electrolyte or with a solid semiconductive metal oxide. Thanks to this type of adhesive, the wound foil will not detach itself in the course of the manufacturing process. Especially in solid electrolytic capacitors, the polymer adhesive used so far were unreliable. As a result of the invention the number of rejects has decreased drastically.
