Description
SPECIFICATION
Connectors for electrochemical storage cells
This invention relates to a connector for interconnecting storage cells; in particular electrochemical storage cells based on alkali metal and chalcogen.
Such cells comprise at least one anode space containing the anolyte and one cathode space containing the catholyte which are separated from one another by an alkali-ionconducting solid electrolyte wall and are confined at least in part by a metal wall, a first current collector being an electrode introduced into the reactant space separated by the solid electrolyte wall, and a second current collector being formed by the metal wall. A connector connected to each current collector allows the storage cell to be electrically conductively connected to at least one further storage cell.
Such rechargeable electrochemical storage cells with solid electrolytes are well suited for the construction of storage batteries with high energy and power density. The solid electrolyte of beta-aluminium oxide, used for exam ple in the case of sodiurn/sulfur storage cells, lets only sodium ions pass. In contrast to the lead storage battery, this means that practically no self-discharge occurs and no secondary effects such as water dissociation in the case of the lead/lead oxide systems occur during charging. The current yield, i.e. the
Faraday efficiency, of a sodium/sulfur storage cell of this type is about 100%.
A plurality of sodium/sulfur storage cells are connected in parallel to form a battery of this type. A plurality of such groups of storage cells connected in parallel are then connected in series. This ensures that within a group consisting of a plurality of storage cells connected in parallel the same state of charge occurs in all the storage cells on account of compensating currents which flow between the said storage cells. From the statistical point of view the total capacities of the individual groups differ less from one another than the capacities of individual storage cells.
In order to produce such a parallel circuit comprising a plurality of such storage cells each storage cell provided for this purpose is electrically conductively connected to the storage cell or the two storage cells arranged in parallel to it. Specially constructed cell connectors are provided for this purpose. Such a cell connector is conductively connected to the two cathode or anode current collectors respectively of the two storage cells to be connected to one another.
Cell connectors, for the manufacture of which copper acts as the basic material, are used for the assembly of the batteries used up till now. In order to protect these cell connectors against corrosion and oxidation they are coated with aluminium. The aluminium is applied by plasma spraying. For producing the electrical contact with the storage cell these cell connectors are advantageously fastened to the latter by screws. This screw fastening has the disadvantage, however, that at the operating temperature of the storage cell which is between 300 and 400 C the copper used for producing the cell connector and the aluminium yield to pressure. This means that these materials flow or creep at the temperatures indicated above. This results in an unaccepta ble increase in resistance on the electrical contact surfaces of the cell connector.This prevents the proper operation of a battery, the storage cells of which are connected together by way of this cell connector.
The invention seeks to provide a cell connector with a very low ohmic resistance which remains free of oxidation layers even over a long period of operation and the electrical contact resistance of which does not increase even at an average operating temperature of 400to. Furthermore, the cell connector is to be constructed such that it may be permanently or detachably secured to a storage cell.
According to the present invention the metal cell connector is formed, at least in given areas, by two or more laminar, electrically conductive layers, which are disposed at least in part one above the other and at least a first one of which has a low contact resistance and a specific mechanical stability and at east a second one of which is resistant to oxidation and has a low ohmic resistance, the electrical contact surfaces of the cell connector being formed by at least one of the two layers.
In one embodiment, the cell connector is in the form of a strip. This is formed in two or more layers at least in given areas. A first layer is formed by a steel strip. The second layer consists of aluminium which is applied to the steel strip by means of plasma spraying. The second layer may also be formed by an alumininium strip which is rolled on to the steel strip. Aluminium is a very light material.
In addition it has the property that even over very long periods of using the storage cells it has no oxidation layers. Furthermore the conductivity 6/p of aluminium related to weight is very great. It amounts to 5.6 m.cm3/ (#.g.mm2) whereas in the case of copper, silver, gold, C-steel, X-steel it only reaches values between 2.8 and 0.14 m.cm3/(#.mm2.g).
The steel strip forming the cell connector has a very low contact resistance which is less than 1 milliohm. Furthermore the steel strip is sufficiently flexible and, nevertheless, provides the cell connector with the mechanical stability which the latter requires. The cell connector can thus be permanently or detachably connected to the current collectors of the storage cells in a simple manner. In particular the cell connector may be welded to the current collectors of the storage cell or may be screwed thereto so as to be detachable. Even after operation over a long period and at an average operating temperature of 300 to 400 C it shows no evidence of yielding to pressure and no increase in the contact resistance. At a normal temperature of 20"C it has a contact resistance of 0.36 milli-ohms.At an operating temperature of 400 C the contact resistance increases slightly in accordance with the temperature coefficients of the specific resistances of the individual materials of the cell connector.
A cell connector according to another embodiment of the invention is formed by a steel strip which is coated on one or both sides with an aluminium layer. The aluminium layer may be applied to the steel strip by plasma spraying or dip aluminizing. Instead of this layer an aluminium strip may also be applied to the steel strip on one or both sides. This is preferably performed by cold or hot plating. It is also possible to weld such an aluminium strip to the steep strip likewise on one or both sides.
In a further embodiment of the invention only the central area of the steel strip is provided with an aluminium layer on one or both sides. Its end areas, which form the electrical contact surfaces of the cell connector, are uncoated in this embodiment. All the cell connectors, which are to be screwed to the current collectors of the storage cells, are provided with at least one eye in the region of their electrical contact surfaces, i.e. in particular at their ends, in each case. In order to screw on the cell connector a screw is inserted in each of these two eyes and screwed into the respective current collector to which the cell connector is to be electrically conductively connected.
A further embodiment of the cell connector according to the invention comprises two steel plates which are disposed at a given distance from one another. The steel plates are positioned in such a way that their longitudinal axes lie in one plane. The gap between these two steel plates is bridged by an aluminium strip which is placed on the two ends opposite one another and is joined thereto. In this embodiment too the two steel plates also form the electrical contact surfaces of the cell connector. They are likewise each provided with an eye if the cell connector is to be screwed or bolted to the current collectors.
A further cell connector may be formed by two or more steel strips, each of the steel strips being coated with aluminium on one or both sides. These steel strips are placed upon one another and joined together in the manner of a stack.
The cell connector according to the invention may alternatively consist of a wire mesh.
This is formed, for example, by two interwoven steel wires which are coated with aluminium. The two ends of this wire mesh are each provided with a steel socket forming the electrical contact surfaces of the cell connector.
The invention is explained and the advance to be attained is illustrated below by way of drawings, in which
Figure 1 is a cell connector in vertical section,
Figure 2 is the complete cell connector illustrated in Fig. 1.
Figure 3 is a cell connector which is coated on one side with aluminium and the contact surfaces of which are formed only by the ends of the steel strip,

Figure 6 is a cell connector formed by two steel plates and an aluminium strip,
Figure 7 is a further variant of the cell connector,
Figure 8 is a cell connector formed from a wire mesh.
Figure 9 is two storage cells which are electrically connected together by way of two cell connectors according to the invention.
The cell connector 1 according to the invention is shown in vertical section in Fig. 1. The sectional plane extends parallel to the longitudinal axis of the cell connector 1. It is in the form of a strip and consists of two laminar layers 2 and 3 placed one upon the other.
The cell connector is essentially formed by a steel strip 2 and an aluminium layer 3. The latter is applied to the steel strip on one side.
It is preferably applied to the steel strip by plasma spraying.
This cell connector is shown complete in
Fig. 2. It is evident from this drawing that the aluminium layer 3 covers the steel strip completely on one side. Instead of the aluminium layer applied by plasma spraying, an aluminium strip 3 may also be applied to the steel strip. An aluminium strip 3 of this type may be joined to the steel strip 2 by cold or hot plating for example. The aluminium strip 3 may also be secured to the steel strip by welding.
The cell connector according to the invention illustrated in Figs. 1 and 2 is approximately 12 mm wide. If conditions require it, the steel strip 2 may also have a different dimension. The thickness of the said steel strip 2 is between 0.1 and 5 mm. The majority of the steel strips have a thickness between 0.3 and 1 mm. The preferred embodiment has a thickness of 0.6 mm.
The length of the steel strip 2 is determined by the conditions in question, in particular the respective distance between the two storage cells to be connected electrically. The aluminium layer 3 applied to the steel strip 2 is approximately 0.01 to 1 mm thick. The preferred embodiment has a thickness of 0.6 mm. In order to obtain an optimum conductivity of the cell connector 1 an aluminium layer 3 with a thickness of 0.05 to 0.4 mm is applied to the steel strips 2. As already mentioned, instead of an aluminium layer applied by plasma spraying, an aluminium strip 3 may also be used for forming the coating on the steel strip 2. The thickness of such an aluminium strip is preferably between 0.02 and 0.6 mm. The two electrical contact surfaces 4 of the cell connector according to the invention, which are situated at its two ends, are each provided with an eye 5.The said eyes are used for the detachable fastening to the current collectors of the storage cells. If conditions require it, the cell connector may also be tightly screwed to a second cell connector used for the purpose of extension. For screw connection the neck of a screw (not shown here) is inserted through each eye and is screwed into the current collector of a storage cell for the purpose of mounting.
A variant of the cell connector 1 illustrated in Fig. 2 is shown in Fig. 3. It is constructed substantially as the cell connector 1 illustrated in Fig. 2 and explained in the appertaining description. It likewise comprises a steel strip 2 which has the dimensions given in the above description. An aluminium layer or an aluminium plate 3 respectively is again applied to one side of this steel strip 2. In this case the aluminium layer 3 is made thicker than in the case of the embodiments described above. In contrast to the cell connector illustrated in Figs. 1 and 2 of the aluminium layer 3 applied on one side does not completely cover the steel strip 2. The aluminium layer 3 is preferably arranged only in the central area of the steel strip and is approximately 30 to 100 mm long.In this embodiment of the cell connector the two electrical contact surfaces 4, which are disposed at the two ends of the steel strip 2, have no coating.
This embodiment of the cell connector is preferably employed when the aluminium layer 3 applied is thicker than 0.4 mm as in this case. In this way, creeping of the aluminium in the region of the contact surface 4, in particular in the vicinity of the eyes 5, is avoided, in particular when the cell connector is screwed to the current collectors and the screws exert pressure on the cell connector. In contrast to this, the embodiment of the cell connector illustrated in Fig. 2 has an aluminium layer 3 which, as already mentioned, has an optimum thickness of between 0.05 and 0.4 mm. The steel strip 2 can thus be provided completely with an aluminium coating in the case of the embodiment of the cell connector shown in Fig. 2 since with such a layer thickness there is no creeping of the aluminium at temperatures of about 400 C.
An aluminium layer of this type is also not affected by the compressive load of the screws.
An embodiment of the cell connector according to the invention is also shown in Fig.
4. This cell connector is formed by a steel strip 2 which is provided with a coating on both sides. The coating is formed by an aluminium layer 3 in each case. As already mentioned above, these two aluminium layers 3 may be applied to the surfaces of the steel strip by plasma spraying or dip aluminizing.
The dimensions of the steel strip 2 correspond to the dimensions of the steel strip 2 illustrated in Fig. 2 and explained in the appertaining description. In the embodiment shown in Fig. 4, instead of the two aluminium layers 3 applied for example by plasma spraying, two aluminium strips may also be joined to the surfaces of the steel strip. The two aluminium strips are joined to the steel strip 2 by cold or hot plating for example. Welding the steel strip 2 to the aluminium strips is likewise possible. The dimensions of the two aluminium layers or strips 3 are selected such that the two surfaces of the steel strip 2 are completely covered. The thickness of the two aluminium layers or strips corresponds to the values described above. In the region of its two electrical contact surfaces the cell connector is provided with eyes 5 for possible screw connection.
A variant of the cell connector 1 illustrated in Fig. 4 is shown in Fig. 5. The construction of this cell connector differs only slightly from the embodiment shown in Fig. 4. This cell connector 1 is formed essentially by a steel strip on to which a further layer 3 has been applied on both sides. The said layers 3 are again two aluminium layers 3 or two aluminium strips 3 respectively, which are joined to the steel strip 2 in the manner described above. This has the same dimensions as the steel strips 2 already described. The steel strip 2 is coated with the two aluminium layers or the aluminium strips 3 in such a way that its two electrical contact surfaces 4 are uncoated on both sides in each case. The two aluminium layers 3 thus extend only over the central area of the steel strip 2.The thickness of the two aluminium layers or aluminium strips is between 0.05 and 0.4 mm in this case too.
The cell connector illustrated in Fig. 6 is formed by two steel plates 2. The length of the two steel plates is approximately 15 mm.
If conditions require it, the steel plates may also be made larger or smaller. The thickness of the two steel plates 2 corresponds to the thickness of the steel plate 2 which is used for producing the cell connector illustrated in
Figs. 1 to 5. The two steel plates 2 are disposed opposite one another by leaving an interspace free, so that their longitudinal axes lie in one plane. The distance between the two steel plates is determined by the desired length of the cell connector. In the preferred embodiment it amounts to approximately 50 mm. The two steel plates are connected together by an aluminium strip 3. This rests with its two ends on one of the two steel plates 2 in each case. The aluminium strip 3 is electrically conductively and non-positively joined to the two steel plates by one of the methods mentioned above.The length of the aluminium strip is determined by the distance between the two steel plates 2. It is preferably between 0.5 and 1 mm thick.
The cell connector 1 illustrated in Fig. 7 is formed by three steel strips 2. Each of these steel strips is coated on both sides with an aluminium layer 3. These aluminium layers 3 may also be replaced by aluminium strips 3 rolled on both sides. The steel strips 3 coated in this way are placed one upon the other in the manner of a stack and are joined to one another. In order to form the cell connector 1 it is possible to coat each of the steel strips with aluminium or to provide them with an aluminium strip on one side only. The steel strips 2 are then preferably placed one upon the other in such a way that the coated side of one steel strip adjoins the uncoated side of the adjacent steel strip in each case.
A cell connector 1, which is in the form of a wire mesh, is shown in Fig. 8. This comprises two, or preferably more, interwoven steel wires. These are provided with a coating of aluminium (not shown here). The two ends of the wire mesh are provided in each case with a steel tab 4. These form the electrical contact surfaces of the cell connector.
Two electrochemical storage cells 6 are illustrated diagrammatically in Fig. 9. These two storage cells belong to one battery (not shown here) and are connected in parallel.
The metal casings of the two storage cells 6 act as the first current collector and are connected together by way of a cell connector 1.
This cell connector 1 is permanently connected to the two metal casings of the storage cells 6. It is constructed in accordance with the embodiment illustrated in Fig. 6 and is provided with two steel plates 2, one steel plate in each case being connected to a casing of a storage cell 6 in each case. The two steel plates 2 are connected together electrically conductively by an aluminium strip 3. The two storage cells 6 both have a further current collector 7 in each case. These two current collectors 7 extend in each case into a storage cell, in particular into the reactant space separated by the solid electrolyte, and project outwards a few millimetres above the storage cells 6. They are likewise connected together by a cell connector 1. This cell connector is constructed in accordance with the embodiment illustrated in Fig. 2. It has a steel strip 2 which is completely covered on one side with an aluminium layer 3 or an aluminium strip 3 respectively. Its contact surfaces 4 are provided with eyes 5 (not shown here). A screw 8 is inserted through each eye 5 and screwed into one current collector 7 in each case.
The cell connector 1 according to the invention is not restricted merely to the embodiment illustrated in Figs. 1 to 8, but it also embraces embodiments which have a larger number of steel strips and aluminium layers or in which the steel and aluminium strips are only arranged in given areas.
