An energy storage assembly includes the following: at least one electrochemical cell, wherein the at least one electrochemical cell comprises an anode that is liquid during operation, an electrolyte that is liquid during operation, and a cathode that is liquid during operation; and a magnetic field-generating structure disposed outside the at least one electrochemical cell for generating a magnetic field, wherein the magnetic field-generating structure is configured such that the generated magnetic field penetrates the at least one electrochemical cell.

Energy storage assembly, use thereof, and energy storage cell assembly

An electrochemical cell assembly has electrochemical cells of large diameter and high storage capacity, making it particularly useful for stabilization of electric supply systems. The assembly includes at least one electrochemical cell composed of a layer of: a liquid metal or liquid metal alloy forming the cathode, a liquid electrolyte layer, and a layer of a liquid metal or liquid metalloid forming the anode. An electrically insulating inner tube is provided along the vertical axis of the assembly, the presence of which prevents the occurrence of the Tayler instability or other instabilities caused in the liquids by the current flow, and thus prevents the intermixing of the liquids. Another very efficient option for increasing the maximum current of the cell is that of conducting a current having a suitable direction and intensity through the interior of the inner tube.
