A fibre electrode consisting of nickel fibres having a mean fibre diameter of 20-50 micrometres is proposed. The electrode carries the separately manufactured fibre structures on both sides, in the form of 0.5 to 2.0 mm thick mats. Located between two fibre mats is an arrester consisting of sheet nickel, nickel metal mesh or a nickel gauze. In contrast to known sintered-powder electrodes, the combination between the fibre structures and the inner arrester can be produced by electrical welding. In this case, in the event of continuous manufacture of the electrode according to the invention, it is important to cycle the welding process onto points or lines successively in time. This can be achieved without any difficulties by electronic control. In contrast, in the case of simultaneous welding, a plurality of mutually independent electrical welding apparatuses must act on the respective combination points of the nickel fibre electrode. |
