Patent number: 4439281Abstract: Electrode structures made from metallized bodies of a fibrous nature, for example from metallized felt, possess the advantage, deriving from their intrinsic stiffness, of requiring no internally fitted supporting structure. It is, however, difficult to attach the current lead-out tabs to an electrode structure of this type, because it is hightly susceptible to mechanical damage at the point of attachment. These difficulties are avoided, according to the present invention, when the edge of the electrode structure is reinforced, to a width of about 0.3 to about 1 cm, by means of an electrodeposited metal coating. If appropriate, the reinforcement of the edge can also be carried out simultaneously with the production, by electrodeposition, of the electrode structure. The current lead out-tab can be attached to the reinforced edge avoiding such difficulties.Type: GrantFiled: October 21, 1982Date of Patent: March 27, 1984Assignee: Deutsche AutomobilgesellschaftInventors: Claus Schneider, Gabor Benczur-Urmossy
