Abstract: Described herein is an electrochemical energy store including at least one electrochemical cell and a support structure, wherein the electrochemical cells are accommodated in a suspended manner in the support structure.

Abstract: An electrode unit for an electrochemical device, comprising (i) a solid electrolyte which divides a space for molten cathode material, selected from the group consisting of elemental sulfur and polysulfide of the alkali metal anode material, and a space for molten alkali metal anode material, and (ii) a porous solid state electrode directly adjacent to the solid electrolyte within the space for the cathode material, with a non-electron-conducting intermediate layer S present between the solid state electrode and the solid electrolyte, wherein this intermediate layer S has a thickness in the range from 0.

Abstract: Provided herein is an apparatus for storing electric energy including at least one electrochemical cell having an anode space and a cathode space that are separated by a solid electrolyte, a first store for anode material that is connected to the anode space, and a second store for cathode material that is connected to the cathode space. The cathode space is also connected to a third store. The second and third stores are connected to one another by means of a gas conduit that opens into the upper region of the second and third stores. A conveying apparatus for gas having a reversible conveying direction is accommodated in the gas conduit. Further provided herein is a method of operating the apparatus.
