Abstract
Such a coated valve metal electrode consists of at least one current feed and at least one current distributor. Current feed and current distributor are mechanically and electrically conductively connected via sheet-like connection elements. The active surface of this electrode consists of lamellas of valve metal having an active surface coating. The essential features of this electrode consist in that the coated overall surface of the lamellas F.sub.A and the surface F.sub.P assumed by the overall arrangement of the lamellas (length and breadth of the electrode surface) have a surface factor such that 20.gtoreq.F.sub.A /F.sub.P .gtoreq.4, preferably such that 14.gtoreq.F.sub.A /F.sub.P .gtoreq.6, and in that the greater proportion of the coated surface of the lamellas is directed perpendicularly to the surface of the strip to be coated.
