ABSTRACT:
An anode riser assembly for an anode means comprising an anode riser means and polymeric means substantially adhered to the anode riser to minimize the ingression of electrolyte means to the anode riser. The anode riser means is made of a film-forming metal and, preferably, does not have a myriad of intercommunicating voids therein. The polymeric means, preferably a polyester material having affixed thereto the trademark Mylar (a trademark of E.I. du Pont de Nemours & Co., Inc.) which is chemically inert to the action of the electrolyte means and has high dielectric strength, substantially adheres to and follows the surface contour of the anode riser means to provide an interface therebetween into which is minimized the ingression of electrolyte means adapted to be cooperatively associated with the anode means. The anode riser assembly is especially adapted for use with anode means in either a dry or wet electrolytic capacitor.
The invention also contemplates a method of making the anode riser assembly.
