Abstract

One aspect relates to a method for producing a ring electrode, including providing an outer element including an outer tube; providing a first inner element, including a first inner tube having a first core made of a sacrificial material, a material of the outer element and a material of the first inner element having a similar microstructure to each other; providing a second inner element, including a second core made of a sacrificial material; forming a composite tube by arranging the first inner element and the second inner element inside the outer element, the first inner element and the second inner element being arranged eccentrically; drawing the composite tube in a longitudinal direction of the composite tube, the material of the outer element and the material of the first inner element retaining a similar microstructure; separating a composite tube disk from the composite tube; removing the sacrificial material of the first core; and removing the sacrificial material of the second core to obtain a contacting opening in the ring electrode.
