Method for contacting an electrically conductive paper structure, composite body and use

A method of contacting an electrically conductive paper structure with a current source, comprising

• the step of providing a support plate having recesses, wherein the support plate has an upper main surface and a lower main surface;
• the step of introducing conductor elements into the recesses of the support plate in such a way that the conductor elements are flush with the upper main surface of the support plate,
• the step of providing an electrically conductive paper structure which has at least one conductor track, preferably at least two conductor tracks, on a main surface;
• the step of joining the support plate and the electrically conductive paper structure to form a composite body in such a way that the electrically conductive paper structure is adjoining the upper main surface of the support plate, wherein the conductor elements of the support plate are in electrical contact with the at least one conductor track, preferably with the at least two conductor tracks, of the electrically conductive paper structure, and wherein the conductor elements of the support plate are contactable with a current source from the lower main surface of the support plate;
• and
• the step of contacting the conductor elements of the support plate with a current source from the lower main surface of the support plate.
