Description

SPECIFICATION A battery The invention relates to a battery comprising single cells combined to form cell blocks.
When batteries consisting of individual, for example galvanic, elements are being operated, operational conditions resulting in an increase oftemperature can arise. Under such conditions the temperatures can reach values which can result in destruction of the structural materials and of the active parts of the cells (electrodes, electrolytes), or unreliable electrochemical reaction processes can occur. On the other hand, it may be required that a certain temperature has to be attained first in order to achieve a capability for an electrochemical reaction.
With galvanic batteries for example in which at least one reactant (air, gas or liquid fuels) or the electrolyte is supplied directly to the cell proper, this fluid can also be used for supplying or removing heat.
With batteries for example, galvanic batteries or stacks of containers filled with metal hydrides in which the individual cells or containers are encased, for example, or in which several individual cells or containers are combined to form cell blocks (modules) and are housed, for example, in a common housing as is the case, for example, with hightemperature accumulators, nickel/hydrogen cells or other systems, it can happen that the supply of an active fluid is inadequate for heat transport or is omitted altogether (accumulators).
According to the present invention there is provided a battery comprising a plurality of single cells combined to form an encased cell block, and a plurality of said cell blocks being arranged in such a manner that spaces therebetween form heat exchange ducts for a cooling or heating medium, wherein a supply duct for the heat exchange ducts has a cross-section tapering down-stream, and a collection duct for the discharge from the heat exchange ducts has a cross-section expanding down-stream, the inlet to the supply duct and the outlet from the collection duct being located diametrically opposite one another.
The heat-absorbing or heat-carrying medium such as, for example air, water, oil or similar, can be supplied and removed advantageously separately.
A particularly simple construction results from arranging the cell blocks in parallel with one another.
By this means a particularly favourable flow of the medium is achieved because this results in a nearly constant pressure along the ducts and equal velocities in the ducts.
Avery simple and well-functioning construction can be achieved in that the inlet and the outlet are located at diagonally opposite corners of an approximately rectangular or parallelogram-shaped chamber.
In particular, the cell blocks can be arranged in a material with both electrically and thermally insulating properties, and for simplifying the construction the main ducts supplying and removing the medium can then be partly constructed of this material.
It can also be advantageous, however, that the main ducts supplying and removing the medium are mounted on the exterior of the battery.
In a preferred embodiment the inlet duct can be located in a plane below the bottom edge of the cell block and the collection duct can be located in a plane above the top edge of the cell block. A particular area of application for the invention are high-temperature accumulators, such as, for example, Na/S batteries, and nickel/hydrogen batteries or blocks of metal containers filled with metal hydrides which require particularly effective cooling due to their construction. In such batteries usually one or several electrode stacks are combined to form one cell block and are enclosed in a common gas-tight pressure housing. These cell blocks (20) are drawn in Figure 1.The heat insulation can be omitted with nickel/hydrogen batteries.
In order to increase the throughput of the medium a blower can be provided at the inlet side of the medium. If heating is required a heater can be provided at the inlet side of the medium.
An embodiment of the invention will now be described by way of example, with reference to the accompanying drawings, in which: Figure 1 shows a section of a battery showing two alternative types of cell block, and Figure 2 shows a section of the battery of Figure 1 in the direction of the arrows Il-Il.
It can be seen from Figure 1 that single cells 1,for example electrolyte tubes of Na/S cells, are arranged vertically with respect to the plane of the drawing and parallel to one another. In each case one row of such single cells, for example connected electrically in parallel, is combined to form a cell block 2 which is enclosed by a sheet metal housing. On the other hand, an arrangement can be selected in which single cells which are encased concentrically are structurally combined in a row to form a cell block.
An arrangement is also possible in which the individual cells are mounted horizontally instead of verticaly. Such an arrangement is shown in the centre of Figure 1 for a Ni/H2 battery, the cell blocks being designated with 20 and the intermediate spaces with 30. In Ni/H2 batteries a cell block consists of several pairs of individual positive and negative plates and is also called a module. For the sake of simplicity in the remaining description merely an enclosed box is indicated. In order to obtain as high a battery voltage as possible, many such cell blocks would be connected in series. The cell blocks 2 are arranged parallel to one another and with small spaces and these spaces form ducts 3 running between the cell blocks 2. A plurality of such cell blocks forms a battery block 4.According to the number of cell blocks required, one or several battery blocks 4 are combined to form a battery (three in the present example).
Na/S batteries work preferably at a temperature of 300 to 350 C. If the battery is fully charged the temperature must reach at least 11 60C for the two reactants, Sodium and Sulphur to be capable of reaction (liquid). For this reason the battery must be brought first to this operating temperature which can be done, for example, via a switchable electric heater coil 5 which follows a blower 6 by which air is pumped through a heating/cooling circuit. In order to maintain the required temperature during operation or during breaks in the operation the whole battery is encased with a material 7 which is both a thermal and electrical insulating material. While electric power is being supplied heat losses arise in the cells. This heat is conducted away via a cooling air stream 8.The air stream is pumped through main ducts 9, 10, 11 and 12 which (see also Figure 2) are partly inserted into the insulation material 7 in this arrangement. The duct 9 is here constructed in such a manner that it is located in a plane below the bottom edge of the cell block 13 (Figure 2) and tapers continuously from the inlet cross-section toward the back. The air can flow only transversely with respect to this duct 9 into the lower distribution duct 10. This duct also tapers in the direction of the flow and forms the distribution duct proper for the air flow into the cell blocks. From the lower distribution duct 10 the air flows through the intermediate spaces 3 or 30 between the cell blocks into the collection duct 11 situated above the cell blocks, wherein the cell blocks serve as conducting elements and the collection duct continuously expands in the direction of the flow.The air flowing through between the cell blocks encounters a large surface which produces a good heat transfer between the walls of the cells and the air flowing through. From the collection duct 11 the air flows over the whole length into the outlet duct 12 located parallel to the inlet duct 9 and extending in a plane above the top edge 14 of the cell block and expanding in the direction of the flow.
From there the air flow reaches the outside or an additional duct or duct system and can be incorporated, for example, in a circulation system (for example a vehicle heating system).
The arrangement shown in the present example does not exclude the use of other heat-absorbing and emitting media.
The symmetrical arrangementforthe conduction of the flow also makes an alternating operation possible, that is one or several media can flow alternatively in the direction from the outlet to the inlet.
Instead of the said galvanic single cells combined to form cell blocks, in other reaction systems can be used, too, which for example lose or absorb heat during their reaction, especially metal hydrides in powder form or in form of sintered bodies, which are contained in metal containers. Such metal containers or "elements" may be combined into blocks or "batteries" in the same manner as shown for galvanic elements.
