Abstract
One aspect relates to a method for a ring electrode, including: providing an outer element with an outer tube and providing a first inner element with 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 have a similar microstructure. A second inner element is provided with a second core made of a sacrificial material; A connection tube is formed by arranging the first inner element and the second inner element within the outer element. The first inner element and the second inner element are arranged concentrically. The composite tube is drawn in a longitudinal direction of the composite tube. The material of the outer element and the material of the first inner element maintain a simialar microstructure. A connection tube disc is seperated from the connection tube. The sacrificial material of the first core is removed and the sacrificial material of the second core is removed to obtain a contacting opening in the ring electrode.
