Abstract: Flow type electrochemical cells are disclosed. The electrochemical cell has an anode half-cell, a cathode half-cell, and permeable separating layer. The half-cells are bounded by side elements. Respective porous electrodes are housed in the half-cells. The permeable separating layer is disposed between the anode half-cell and the cathode half-cell. An electrolyte region connected to an electrolyte feed and an electrolyte outflow region connected to an electrolyte drain are further provided. An electrolyte inflow region and an electrolyte outflow region are disposed on opposite sides of the porous electrodes such that inflowing electrolyte flows through the porous electrode perpendicularly to the permeable separating layer.

Abstract: An energy storage system employing a reversible salination-desalination process includes an electrochemical desalination battery (EDB) unit including an anode and a cathode. The EDB unit runs a salination process while storing energy from a direct current power supply unit, and runs a desalination process while releasing energy to an electrical load. The energy storage system can store power from a variable output electrical power supply unit such as solar cells and wind turbines while running a salination process, and release energy, e.g., during peak energy demand hours while running a desalination process. Combined with a capacitive deionization (CD) unit, the energy storage system can generate fresh water by running desalination processes in the EDB unit and the CD unit while releasing stored energy from the EDB unit. The energy storage unit can function as a dual purpose device for energy storage and fresh water generation.

Abstract: The invention relates to an arrangement and a method for the controlled discharge of an energy store using redox shuttle additives and to the use of redox shuttle additives for the controlled discharge of an energy store. The energy store arrangement comprises a storage container with a redox shuttle additive which is dispensed into the electrolytes of the energy store upon triggering a dispensing device such that the energy store is partly or completely discharged, wherein the redox shuttle additive is oxidized on the cathode and reduced on the anode. The redox shuttle additive has a redox potential which is less than or equal to the potential of the partially or completely discharged cathode and greater than or equal to the potential of the partially or completely discharged anode.
