Abstract:
1. An apparatus for the storage of electric energy by means of materials A and S which form a redox pair and are present separately from one another, wherein a) the apparatus comprises the materials A and S, b) the materials A and S are contained separately from one another in containers BA and BS which are arranged one above the other, c) the containers BA and BS are joined by a solid electrolyte E which is permeable to cations, and d) the containers BA and BS are contained in an overall container, wherein the apparatus comprises at least two overall containers comprising containers BA and BS joined by means of a solid electrolyte E; wherein at least one container BA or BS comprises a displacement body to reduce the volume of the material A and/or S wherein the material A is an alkali metal and the material S is sulfur; wherein the alkali metal is present as a melt and is kept in the interior of a plurality of ceramic tubes which are made of the electrolyte E and are closed at the bottom and the spaces communicate via riser tubes with a common alkali metal reservoir above.
