Abstract

Eine derartige beschichtete Ventilmetall-Elektrode be­ steht aus mindestens einem Stromzuleiter 10 und minde­ stens einem Stromverteiler 20. Stromzuleiter 10 und Strom­ verteiler 20 sind über blechartige Verbindungselemente 30 mechanisch sowie elektrisch leitend verbunden. Die aktive Fläche 40 dieser Elektrode besteht aus Lamellen 41 aus Ventilmetall mit einer aktiven Oberflächenbeschichtung. Such a coated valve metal electrode be consists of at least one power supply 10 and min least a power distributor 20. Power supply 10 and power distributors 20 are via sheet-like connecting elements 30 mechanically and electrically connected. The active one Surface 40 of this electrode consists of lamellae 41 Valve metal with an active surface coating.

Die wesentlichen Merkmale dieser Elektrode bestehen darin, daß die beschichtete Gesamtoberflaïche der Lamellen FA und die von der Gesamtanordnung der Lamellen einge­ nommene Fläche FP (Länge und Breite der Elektrodenfläche) einen Flächenfaktor
20 ≧ FA : FP≧ 4, vorzugsweise
14 ≧ FA : FP≧ 6, aufweist, und daß die größeren Anteile der beschichteten Oberfläche der Lamellen senkrecht zur Fläche des zu beschichteten Bandes ausgerich­ tet sind. The essential features of this electrode are that the coated total surface of the fins F A and the area F P occupied by the overall arrangement of the fins (length and width of the electrode surface) have an area factor
20 ≧ FA: F P ≧ 4, preferably
14 ≧ F A : F P ≧ 6, and that the larger portions of the coated surface of the lamellae are aligned perpendicular to the surface of the strip to be coated.
