    Abstract: Electrode unit for an electrochemical device, comprising a solid electrolyte (3) and a porous electrode (7), wherein the solid electrolyte (3) separates a space for cathode material and a space for anode material and the porous electrode (7) is connected in surface-area contact to the solid electrolyte (3), wherein a displacer (23) is accommodated in the space for anode material, wherein the displacer (23) is produced from a high-grade steel or from graphite foil and comes to lie against the inner geometry of the solid electrolyte (3) in a resilient manner such that the displacer (23) does not contact the solid electrolyte over the full surface area, or wherein the displacer comprises an outer shell (62) made of high-grade steel or graphite and a core (64) made of a nonferrous metal, wherein the nonferrous metal is thermoplastically deformable at a temperature that is lower than the temperature at which the high-grade steel is thermoplastically deformable, and wherein, for production, the high-grade steel or graphite shell (62) is pressed against the solid electrolyte (3) by introducing and heating the nonferrous metal and, during cooling down, a gap forms between the solid electrolyte (3) and the high-grade steel shell (62).
