Definitions
- the invention relates to an energy storage cell, comprising at least one electrode-separator arrangement, which is accommodated in a housing.
- Energy storage systems in particular rechargeable storage devices for electrical energy, are widespread, especially in mobile systems.
- Rechargeable storage devices for electrical energy are used, for example, in portable electronic devices such as smartphones or laptops.
- rechargeable stores for electrical energy are increasingly being used to provide energy for electrically driven vehicles.
- a wide range of electrically powered vehicles is conceivable, in addition to passenger cars, for example, two-wheelers, vans or trucks.
- Applications in robots, ships, airplanes and mobile work machines are also conceivable.
- Other areas of application for electrical energy storage systems are stationary applications, for example in backup systems, in network stabilization systems and for storing electrical energy from renewable energy sources.
- a frequently used energy storage system is a rechargeable storage device in the form of a lithium-ion battery.
- lithium-ion accumulators Like other rechargeable storage devices for electrical energy, lithium-ion accumulators usually have a number of storage cells which are installed together in one housing. A number of storage cells that are electrically connected to one another are usually combined to form a module. The energy storage system does not only extend to lithium-ion accumulators.
- Other rechargeable battery systems such as lithium-sulfur batteries, solid-state batteries, sodium-ion batteries or metal-air batteries are also conceivable energy storage systems.
- supercapacitors can also be used as an energy storage system.
- Energy storage systems in the form of rechargeable storage have the highest electrical capacity and the best power consumption and output only in a limited temperature range. If the optimum operating temperature range is exceeded or fallen below, the capacity, the power consumption capability and the power output capability of the storage device drop sharply and the functionality of the energy storage device is impaired. Temperatures that are too high can also irreversibly damage the energy store. Accordingly, both permanently occurring elevated temperatures and short-term temperature peaks should be avoided at all costs. In the case of lithium-ion accumulators, for example, temperatures of more than 50° C. and short-term temperature peaks of more than 80° C. should not be exceeded over the long term.
- the energy storage systems In particular in the case of applications in passenger vehicles, the energy storage systems must be able to be charged quickly.
- the accumulators forming an energy storage system should be fully or almost fully charged within a short time, for example within 15 minutes. Due to the efficiency of the charging system of about 90% to 95%, large amounts of heat are released during the charging process in the energy storage system, which must be dissipated from the energy storage system. These amounts of heat are not released in normal operating conditions. It is therefore necessary to design the cooling system of the energy storage system in such a way that the amount of heat that occurs during the charging process can be absorbed.
- thermal runaway is particularly important for lithium-ion cells. known.
- large amounts of thermal energy and gaseous decomposition products are released in a short time, resulting in high pressure and high temperatures in the housing.
- This effect is particularly problematic in the case of energy storage systems with a high energy density, as is required, for example, to provide electrical energy in electrically powered vehicles.
- the problem of thermal runaway increases as a result of increasing amounts of energy in the individual cells and increasing the packing density of the cells arranged in the housing.
- temperatures in the range of 600 °C to 1,000 °C can develop on the housing wall of the cell over a period of several minutes.
- the device for thermal insulation must withstand such stress and reduce the energy transfer to neighboring cells in such a way that the temperature load on the neighboring cells is no more than 150 °C. It is essential to limit the energy transfer to neighboring cells in order to prevent them from thermally running away as well.
- lithium-ion storage cells are subject to a change in volume, with the volume increasing as the service life increases. In the case of pouch cells, this is noticeable, for example, by bulging.
- the change in volume of the storage cells must be compensated for by the device. Either this is done by the storage cells being braced against one another, which is associated with a very large increase in pressure.
- compression elements are arranged between the storage cells, which absorb volume changes of the storage cells.
- the thermal insulation effect decreases with increasing compression; the heat transfer is usually inversely proportional to the distance between the storage cells.
- the object of the invention is to provide an energy storage cell which has improved performance characteristics.
- the energy storage cell according to the invention comprises at least one electrode-separator arrangement which is accommodated in a housing, with a covering being arranged at least in sections between the electrode-separator arrangement and the housing, the covering being made of porous material.
- the design of the covering from porous or pore-containing material enables the design of a covering with elastic, isolating and electrically isolating properties.
- elastic also means reversibly deformable. But so is the cover designed in such a way that both electrical insulation and thermal conductivity are provided.
- the material can be open-pored.
- the casing is suitable for accommodating a liquid, in particular an electrolyte, which at least partially fills the area between the electrode-separator arrangement and the housing.
- the cover is preferably elastic.
- the cover can compensate for cyclic volume changes in the electrode-separator arrangement, which can arise on the one hand from different states of charge and on the other hand also as a result of the life cycle of the electrode-separator arrangement. Due to the deformability, the increase in volume of the electrode-separator arrangement can be compensated for when filling with the electrolyte.
- elastic also means reversibly deformable.
- the casing can also be designed as a cover in the area of the end faces of the electrode-separator arrangement.
- the deformable behavior can compensate for tolerances in the electrode-separator arrangement which result from the manufacturing process.
- the covering can be formed from a fibrous structure.
- the cover can be made of a textile fabric, a paper-like material or the like.
- the cover is made of a non-woven fabric.
- Nonwovens are textile fabrics that can be produced in such a way that they have porosity, elasticity and deformability that are optimized for the technical function of the cover and can also ensure the function of electrical insulation.
- nonwovens Due to the fibre-based structure, nonwovens have high mechanical strength, which can be improved by additional measures. For example, mechanical strength can be improved by heat setting, in which fiber crossing points are fused together.
- Non-woven fabrics have a high tear resistance and are resistant to penetration by particles. Such particles can result, for example, from processing errors in cell production. If electrically conductive particles penetrate the casing, an electrical short circuit can occur between the electrodes and the wall of the housing. When using a non-woven fabric, it is advantageous that such particles can be embedded in the matrix of the fiber structure without cracks forming.
- non-woven fabrics have a reversible compressibility, which is preferably in the range of 30% in the case of the cover according to the invention. Such a compressibility supports the volume compensation of the electrode-separator arrangement in the area of all states of charge and also in the case of age-related growth in thickness.
- the casing within the energy storage cell can absorb typical changes in thickness of electrode-separator arrangements and reduce mechanical compression of the electrode-separator arrangement.
- Through-holes pinholes
- the fiber arrangement having a high level of homogeneity the fibers of the fiber arrangement having a small fiber diameter, the porosity selected not being too high, or many layers being realized over the thickness of the cladding.
- the cover can be formed from a wet fleece.
- wet webs it is particularly advantageous that they have a particularly homogeneous and smooth surface. This is particularly advantageous on the surface facing the electrode-separator arrangement because the occurrence of local pressure peaks can be avoided by the homogeneous surface, which can lead to cell damage in the long term. It is particularly advantageous in this connection that the homogeneity of the electrode-separator arrangement can be compensated for in the case of a mechanically deformable design of the casing. For example, local bulges, which at local
- the fiber structure can include plastic fibers, glass fibers and/or ceramic fibers. These fibers are electrically insulating.
- the cover can be formed from a spunbonded fabric, with meltblown spunbonded fabrics being particularly suitable. Due to the production process, spunbonded nonwovens have particularly little contamination, so that the risk of contamination entering the energy storage cell is reduced.
- cover from a dry fleece. Dry webs can be produced particularly well anisotropically and are therefore suitable for coverings which are exposed to particularly high mechanical loads in a preferred direction.
- the porosity of the coating is preferably at most 70%. This can ensure that the casing is electrically insulating. Likewise, increasing porosity also results in increasing compressibility and elasticity. However, it must always be ensured that the cover is electrically insulating and has a certain thermal conductivity.
- the mean pore size is preferably between 3 ⁇ m and 40 ⁇ m. Such a configuration results in advantageous properties with regard to electrical insulation, thermal conductivity and elasticity.
- the cover can be multi-layered.
- the covering is preferably made up of at least five, preferably at least eight, fiber layers. This results in a high mechanical restoring force in order to support thickness compensation of the electrode-separator arrangement. Due to the multiple layers, it can be ensured that open pores are present even in the maximally compressed state, with the occurrence of continuous pores (pinholes) being able to be ruled out. With a coating thickness of 100 m, for example, 10 fiber layers with a thickness of 10 ⁇ m each can be realized. Finer fibers lead to an improvement in homogeneity and a reduction in the risk of open pores.
- the fiber structure can consist of fibers with a similar fiber diameter or of a fiber mixture with stronger structural fibers and finer homogeneity-improving fibers. The use of microfibrillated fiber bundles (pulps) as homogeneity-improving components is also conceivable.
- the porosity of the cover results in an additional reservoir for electrolyte.
- an energy storage cell with the dimensions 250 ⁇ 100 ⁇ 30 mm results in an additional electrolyte volume of approximately 3.4 cm 3 .
- This additional electrolyte volume can counteract aging processes in the electrode-separator arrangement.
- Ceramic particles can be embedded in the casing.
- the ceramic particles can improve the thermal conductivity and also the electrically insulating properties of the encapsulation.
- inorganic particles for example aluminum oxides, aluminum hydroxides or silicon dioxides, which are introduced into the spaces between the fibers, are conceivable.
- Ceramic fillers make it possible to design a thermally stable design of the insulation layer. Temperatures that occur during thermal runaway of the cell do not lead to immediate destruction of the casing; electrical isolation is maintained.
- An electrolyte which contacts the casing can be accommodated in the housing. Through the pores of the material of the cover, the electrolyte can be accommodated in the cover itself, so that additional electrolyte can be contained in the housing. In particular, the thermal conductivity between the electrode-separator arrangement and the housing can also be improved by the electrolyte. It is advantageous here that, compared to a closed envelope, an additional amount of electrolyte can be introduced into the energy storage cell, which can be used as an additional reservoir is available and leads to improved properties in particular at the end of the life of the energy storage cell.
- the material of the cover in particular the fiber material of the cover, can be designed in such a way that it can be wetted by an electrolyte arranged in the housing. This can support the wetting of the electrode-separator arrangement, which is particularly advantageous during the filling process. This can be achieved by selecting fibrous materials for the sheath.
- polar polymers such as polyamides or polyesters can be wetted with an electrolyte.
- hydrophilization processes for example gas-phase fluorination, plasma treatment, grafting with polar substances such as acrylic acid, or sulfonation, can lead to permanently effective wettability for the electrolyte.
- wetting agents are also conceivable, which speeds up the filling process in particular. Furthermore, it is advantageous that, in the case of wettable gas bubbles, they are expelled from the cell housing during the filling process. This is not necessarily the case, for example, with foil-based coverings.
- the cladding enables thermal conductivity through the plane.
- the heat transfer from the electrode-separator arrangement through the casing in the direction of the housing can be improved.
- the temperature of the energy storage cells is controlled from the outside via the housing.
- Improved thermal management of the electrode-separator arrangement can be achieved through the thermal conductivity of the casing.
- the thermal conductivity improves in particular when the pores are filled with electrolytes. Electrolytes usually have a comparatively high thermal conductivity.
- circulation of the electrolyte within the porous casing caused by convection can be achieved, which supports effective temperature equalization. The circulation increases with increasing temperature difference.
- thermo conductivity of the electrolyte and the use of convection enable improved thermal management of the energy storage cell, independently of any thermally insulating properties of the fiber material of the casing.
- the cover can be provided with an adhesive surface. This allows the cover to be placed against the electrode-separator unit during assembly. This avoids the need for additional adhesive tapes, which can result in local thickening.
- adhesive surfaces based on acrylate binders are conceivable here.
