Definitions
- the invention relates to a battery consisting of at least two
- batteries are made up of individual cells. These are usually housed in a housing and sometimes also divided into so-called “stacks.” Typically, a battery for hybrid or electric vehicles or for industrial applications, in particular for
- These individual cells can be designed as round cells or as prismatic cells, which both have a fixed housing, or else as so-called “coffee bag cells”, in which the housing is configured as a metal foil coated on both sides prismatic cells or “coffee bag cells” used.
- Lithium batteries are even more critical than NiMH batteries as they show higher energy density, thinner separators, a combustible electrolyte, higher voltages and lithium.
- Temperature should be kept as constant as possible in the battery. A temperature difference of maximum 3 K is ideal and allowed
- Another disadvantage is that the potting compounds creep. An undesirable penetration of the potting compound between two contacts can therefore not be excluded.
- the invention is therefore based on the object of specifying a battery whose cells are durable after simple production and positioning
- the present invention achieves the aforementioned object by the features of patent claim 1.
- the aforementioned battery is characterized in that the intermediate space is filled with a porous and deformable compensating element for controlling the temperature of the cells.
- the arrangement of a porous and deformable compensating element between the cells of a battery causes several positive effects. Due to its compressibility tolerance compensation during production can be ensured. It is avoided that the cells are pressed too hard during manufacture and thereby damaged. It also ensures that electrical connections at the top of the cells become easily flexible.
- the compensating elements located between the cells serve, among other things, as a mechanical buffer. This is particularly advantageous when bumping on the battery. Especially with lithium cells occurs during electrochemical processes, a volume work, which is transferred to a flexible housing in so-called “coffee bag cells.” Typical values between maximum and minimum volume are thereby 3 - 5% "Coffee Bag Cells" compensation elements are compensated.
- the use of porous compensating elements further allows for uptake of electrolytes which may leak out of the cells in the event of failure of the battery.
- the compensating element could have a thermally conductive surface. This is advantageous to ensure a good and fast cooling or heating of a battery. It is also advantageous that a cold battery can be quickly brought to operating temperature. It is advantageous to heat batteries at temperatures below 0 ° C, as cold batteries are not powerful are like moderately warm batteries. This is due to a lower capacity and smaller tapped currents. Furthermore, charging cold lithium batteries, especially at high currents, can lead to increased dendrite formation. Dendrites are conductive crystal growths that can lead to micro-shorts.
- the temperature of the cells can be done in several ways. There could be a contact cooling via the two metallic electrode-Ableitbleche. This is a preferred method because heat transfer across the electrodes into the cell is most effective. In addition, the electrodes are usually rigidly connected, so that contacting the cooling is easily possible.
- a contact cooling could take place via the sealing seam of a cell. This too is used in practice.
- the heat transfer at the interface seal seam - cell interior is lower than in the cooling of the two electrode Ableitbleche, since the cell film both sides with thermally non-conductive
- Heat transfer through the film into the cell interior is a factor of 10 - 100 worse than with cooling via the electrode discharge plates. This is related to the layered structure of the cell interior. In the case of planar cooling, the heat must be dissipated vertically through the layer structure of the conductive electrodes and the non-conductive separator. In addition, the cell area itself is not fixed due to the volume work of the cell per se, since charged cells are about 5% thicker than uncharged ones. This complicates a thermal contact. Especially with this type of cooling There are significant advantages, which are shown in the following table:
- a highly porous, elastic material with high restoring force is used as compensation element.
- a highly porous, elastic material with high restoring force is used as compensation element.
- Compensation element Is there no mechanical contact, for example, due to an air cushion between the compensation element and the
- the compensation element must be able to follow the expansion of the cell in the z-direction.
- that must Compensation element be thermally conductive at least on the cell-facing surface.
- Compensating elements are technically preferred, but certainly not optimal for cost reasons.
- a flexible, reversibly compressible and at least at one surface thermally conductive open-pore material with total porosity in the unloaded state of more than 20% is particularly preferred. This porosity allows compression in the z-direction, which can follow the change in thickness of the cells. The reversibility ensures that the compensation element can follow the thinning cells or the cell surface and thus always a mechanical contact to the surface is made.
- a nonwoven fabric could be laminated onto thermally conductive textile substrates or films.
- the nonwoven fabrics - could also have carbon fibers or a metal coating.
- the nonwoven fabrics have thermally conductive properties. They offer excellent thermal conductivity and flexibility at the same time.
- the entire nonwoven fabric could be designed to be conductive. This can be achieved by thermally conductive fibers, metal, graphite, carbon, carbon nanotubes, fibers with metal coating, obtained by electrodeposition or CVD deposition, thermally conductive particles, metal, ceramic, especially AI2O3, carbon black, especially conductive carbon black, graphene and / or other conductive carbon modifications.
- Thermally conductive fibers or threads, in particular metal fibers could be introduced into the nonwoven fabric.
- Polymeric fibers of polyamide, polyester, polyacrylonitrile or polyvinyl alcohol could also be used.
- "coffee bag cells” can be homogeneously tempered over their entire surface by a thermally conductive nonwoven fabric Against this background, it is conceivable that the nonwoven fabrics with Al2O3, SiC, glass, Leitruß, graphite foils, aluminum foils or metal fibers are equipped.
- the compensating element could be connected to a heating or cooling device to effect the temperature control of the cells.
- the heating allows active heating of the cells.
- the cooling device actively cooling the cells.
- the compensating element could be designed as a layer and surround the cells in a zigzag shape.
- a single layer can be used to envelop a plurality of cells at least partially.
- the layer is configured as a nonwoven, paper, fabric, scrim or knitted fabric.
- the compensating element could comprise an elastomeric material or be configured as an elastomeric layer. It is also conceivable to position several layers between two cells.
- the elastomeric material could be thermally conductive in order to cool the cells, to heat or to keep their temperature constant.
- the elastomeric material could be designed as a shaped part with grooving analogous to a chocolate bar structure.
- the elastomeric material can act as a frame for "coffee bag cells".
- the compensation element has a foam or is made of a foam. Foams can be open-pored and allow the blowing off of gases.
- the compensating element could comprise a nonwoven fabric or be made of a nonwoven fabric.
- the arrangement of nonwovens between the cells of a battery causes several positive effects. The compressibility of nonwovens ensures tolerance compensation during production. It is avoided that the cells are pressed too hard during manufacture and thereby damaged. It also ensures that electrical connections are made easily flexible at the top of the cells.
- the nonwoven fabrics lying between the cells serve as a mechanical buffer. This is particularly advantageous when bumping on the battery. Especially in lithium cells occurs during electrochemical processes, a volume work, which is transmitted to a flexible housing in so-called "coffee bag cells.” Typical values between maximum and minimum
- volume is 3 - 5%. This voluminous work can be compensated by non-woven fabrics lying between the "coffee-bag cells.”
- Nonwovens which can escape from the cells in case of failure of the battery. This effect is particularly advantageous when recycling the battery because it does not drip.
- the open-pore design of nonwovens further allows the rapid outgassing or blowing off of an electrolyte in the event of an external short circuit of the battery.
- Nonwovens, especially those with high porosity have a low density.
- a polyester nonwoven having a polymer density of 1.4 kg / l has a density of only 0.7 kg / l at a porosity of 50%.
- the compensating element could be equipped flame-retardant. So-called "fireblocker” nonwovens are advantageous for suppressing fires emanating from the battery.
- the compensation element could have adhesives. By applying adhesive mass adhesives in particular nonwovens may be slightly tacky. As a result, the nonwoven fabrics can be easily arranged and fixed during battery production. against this background, it is conceivable that hot melt adhesives are used. Hotmelt adhesives are easy to process.
- the compensating element could comprise superabsorbent materials. This allows moisture management in the battery. The use of non-woven fabrics with water-binding properties could avoid condensate in the battery. This can be done with the help of absorbent or
- the compensating element could imprints, especially deep-drawn
