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.

Electrochemical energy store

Described herein is a process for the production of moldings made of porous material impregnated with polysulfide, the process including the following steps: (a) insertion of the porous material into a mold; (b) introduction of liquid polysulfide into the mold at a flow velocity within the porous material in the range from 0.5 to 200 cm/s; (c) cooling of the polysulfide to a temperature below the melting point of the polysulfide; and (d) removal of the porous material impregnated with the polysulfide.

Method for producing moulded parts consisting of a porous material impregnated with polysulfide

A device for storing electrical energy is disclosed. The device includes an electrochemical cell having a cathode chamber for holding a liquid cathode material and an anode chamber for holding a liquid anode material. The cathode and anode chambers are separated by a solid electrolyte, wherein the solid electrolyte is surrounded by a planar construction having openings, through which the cathode material can flow. The planar construction is made of an electrically conductive material. The cathode chamber includes at least one segment, wherein each segment has a jacket composed of an electrically conductive material and the jacket is fastened to the planar construction having openings in a fluid-tight and electrically conductive manner and wherein each segment is filled with a porous felt or a porous material different from porous felt. A method for assembling and starting up the device and a method for operating the device is also disclosed.

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 0.5 to 5 mm and, before the first charge of the electrochemical device, has been impregnated fully with a polysulfide composition, comprising (A) pure polysulfides MetSwith Met=alkali metal of the alkali metal anode material selected from lithium, sodium, potassium, and x is dependent on the alkali metal and is 2, 3, 4 or 5 for Na and is 2, 3, 4, 5, 6, 7, 8 for Li and is 2, 3, 4, 5, 6 for K, or (B) mixtures of the polysulfides of one and the same alkali metal from (A) with one another.

Electrode unit for an electrochemical device

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.

Device for storing electrical energy and method for operating the device

The invention relates to an electrode unit for an electrochemical device, comprising a solid electrolyte () and a porous electrode (), the solid electrolyte () dividing a compartment for cathode material and a compartment for anode material and the porous electrode () being extensively connected to the solid electrolyte (), with a displacer () being accommodated in the anode material compartment, where the displacer () is manufactured from a stainless steel or from graphite foil and bears resiliently against the internal geometry of the solid electrolyte () in such a way that the displacer () does not contact the solid electrolyte over its full area, or with the displacer comprising an outer shell () of stainless steel or graphite, and a core () of a nonferrous metal, the nonferrous metal being thermoplastically deformable at a temperature which is lower than the temperature at which the stainless steel is thermoplastically deformable, and where for production the shell () of stainless steel or graphite is pressed onto the solid electrolyte () by introduction and heating of the nonferrous metal, and on cooling forms a gap between solid electrolyte () and shell () of stainless steel.
