Abstract
One aspect relates to a production method for a ring electrode, to a ring electrode, and to an electrode system. One method for the ring electrode includes providing an outer element, including an outer tube, providing a first inner element, including a first inner tube having a first core of a sacrificial material, providing a second inner element, including a second core 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 off-center with respect to one another, drawing the composite tube in a longitudinal direction of the composite tube, 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 in order to obtain a contacting opening in the ring electrode.
