Definitions
- the present invention relates to an electrochemical cell for reversible storage of electrical energy using the redox reaction
- EP 2 541 646 A1 describes a current version of the electrochemical cell here with an electrolyte in the shape of a clover leaf, a complex shim structure that includes the electrolyte, and an anode space for liquid sodium between the ceramic electrolyte and the housing.
- US 2017/0104244 A1 describes an electrochemical cell of the same type.
- the current conductor for the positive electrode is arranged centrally and surrounded by the cathode mass.
- the amount of cathode mass and thus the cell capacity is limited by the size of the ceramic electrolyte and reduced by the volume of the current arrester.
- WO 94/23467 A2 describes the active components of this type of electrochemical cell.
- the US 4,722,875 A discloses an electrochemical cell which is based on the known redox system and has an impregnated mixture which has a Forms cathode of the electrochemical cell and is separated from an alkali metal anode by an electrolyte separator in the solid state.
- NaS battery cells also use a ceramic that is conductive for Na t ions and that with this cell type the negative electrode is arranged inside the ceramic tube and the sulfur electrode is arranged outside the ceramic tube.
- the reasons for this arrangement are the need for a sodium safety cartridge, which can only be arranged within the ceramic tube, on the one hand, and the installation of the sulfur cathode in the form of preformed shells on the other.
- the object of the invention is in particular to provide a device for storing large amounts of electrical energy using the above mentioned redox reaction, which has a capacity of 200 Ah to over 300 Ah and at the same time allows a complete discharge in less than or equal to 10 hours .
- the invention relates to an electrochemical energy storage device, in particular an electrochemical cell, based on the redox Na / MCL, with a Na t ionically conductive ceramic electrolyte and a salt as FLÜS sigen electrolyte, a cathode space outside an electrolyte tube and an anode space within an electrolyte tube is arranged.
- the electrochemical energy storage device in particular the electrochemical cell, comprises a cell housing which has a hemispherical cell base. This shape of the cell housing advantageously contributes to enabling the electrochemical energy storage device, in particular the electrochemical cell, to have a large capacity.
- the ceramic electrolyte is the most expensive component of the cell. By arranging the cathode outside the electrolyte tube, significantly more active material can be accommodated relative to the tube, which reduces the costs related to the energy content.
- the ratio of the volume of the active cathode mass to the volume of the active anode mass is roughly 2 to 1, which is why it is actually unfavorable to arrange the cathode in the limited interior of the electrolyte tube, because this only allows cells with a relatively low capacity to be produced. It is therefore the task of this invention to enable significantly larger capacities when using the same electrochemical system.
- the active material of the cathode in the form of granules is poured into the cathode compartment and then vacuum-impregnated with a molten salt as a liquid electrolyte.
- the cathode space is tubular with a closed end, which is why the filling process and the impregnation process can only take place from the upper end. Because of the frequent formation of bubbles when the granulate meets the liquid salt, the impregnation process is considerably hindered. This disadvantage of the known solution is also intended to be eliminated according to the invention.
- FIG. 1 shows a cross section through a cell 10 according to the invention. It comprises a cathode space 11 arranged outside the ceramic electrolyte 12, an anode space 13 located inside the ceramic electrolyte 12 and a shim tube 14 which has a capillary gap 15 to the ceramic electrolyte forms.
- the shim tube extends from the beginning of the cylindrical part of the ceramic electrolyte tube 16 to the top, where it narrows to a smaller diameter 14. As a result, the capillary gap widens and the sodium can no longer rise higher.
- the anode space 13 of a more or less charged cell is filled to a greater or lesser extent with liquid sodium.
- the shim tube 14 is intimately connected to the cell cover 18, for example by friction welding.
- the cell cover also serves as the negative pole of the cell.
- the cell housing 19 is made of a metal whose electrical potential must not be lower than that of nickel.
- a ring cover 20 closes the cell housing.
- In the ring lid there is an opening 21 into which the active material is filled in the form of dry granules.
- a second opening 22 which is used for vacuum impregnation of the active material. After completion of the filling and impregnation process, both openings 21, 22 are metically closed.
- the cell bottom 23 is hemispherical, whereby this part of the cell also contributes to the capacity.
- Support ring made of non-ion-conductive ceramic
