Description

Technical Field

[0001] The present invention relates to protective elements for arrangement on or in a device, and to devices having such protective elements. Background Technology

[0002] Many devices, especially energy storage devices, are subjected to significant challenges and / or loads.

[0003] For example, during operation and / or storage, climatic and / or mechanical effects, such as those that load the equipment, often occur.

[0004] This type of load not only leads to reduced efficiency, but can also cause damage or even failure of the equipment.

[0005] Therefore, so-called thermal runaway (i.e., exothermic chain reaction; also known as thermal escape) in energy storage devices, for example, poses a great potential danger.

[0006] According to current technology, shells made of special polymers and single-layer or multi-layer metal shells (e.g., made of cast aluminum) are known. Shells with additional, internal protective layers (e.g., made of mica moldings) are also known.

[0007] In addition, functional coatings are known, such as intumescent paints for improving fire resistance, anti-corrosion paints, or paints for improving (electrical) breakdown strength.

[0008] Given the wide range of requirements, the known methods are highly diverse. However, these methods often fail to provide comprehensive protection. For example, a combination of materials sufficient to resist thermal runaway in a battery cell may prove disadvantageous, for instance, due to its own weight.

[0009] A combination of materials that provides adequate protection against electrical breakdown may be unsuitable, for example, in terms of thermal requirements.

[0010] The variations in material combinations and solutions are even more diverse than the requirements imposed on them. Therefore, no system that fully meets both technical and commercial requirements is currently known. Summary of the Invention

[0011] Therefore, the object of the present invention is to provide a protective element and a device that are adapted to different protection requirements and at least reduce the above-mentioned disadvantages.

[0012] Regarding the protective element, the objective according to the invention is achieved by a protective element having the features of claim 1. Regarding the device, the objective according to the invention is achieved by a device having the features of claim 17.

[0013] Advantageous design options, improvements and variations are given in the dependent claims.

[0014] The advantages and preferred design schemes listed regarding protective elements can be reasonably applied to the device, and vice versa.

[0015] Specifically, the purpose of the protective element is achieved by a protective element that is arranged on or in the device.

[0016] In particular, the device can be an electrical energy storage device, such as a box having one or more batteries or battery cells.

[0017] In alternative implementations, the protective element may also be part of the device, such as part of an electrical energy storage device.

[0018] In particular, the protective element in this case can preferably be part of the housing or arranged between the individual cells of the energy storage device, such as battery cells. In this case, the protective element preferably forms a so-called inter-cell protective element.

[0019] Advantageously, the protective element has a load-bearing structure and at least one insulating layer and at least one connecting layer.

[0020] It may be advantageous for the load-bearing structure to be protected and / or shielded thermally and / or mechanically and / or chemically by one or more insulating layers, particularly to spatially isolate it from thermal effects. Alternatively or additionally, it may be specified that the load-bearing structure is protected and / or shielded thermally, mechanically and / or chemically by means of one or more insulating layers.

[0021] Mechanical protection is preferably achieved, in particular, by using a material that is mechanically robust and abrasion-resistant when subjected to hot gas carrying particles, especially from the battery cell that is releasing gas.

[0022] The load-bearing structure preferably forms a core of the protective element.

[0023] The load-bearing structure is preferably formed of a solid material, that is, it does not have, for example, air and / or material inclusions made of other materials.

[0024] Alternatively, the load-bearing structure can preferably be formed as a support. The load-bearing structure can also preferably have gaps. For example, a material different from the support material can be introduced into the gaps. For example, the gaps can contain air to form a lightweight load-bearing structure.

[0025] At least one insulating layer is preferably used to isolate and thus protect the device from various influences.

[0026] Preferably, the connecting layer is used to connect the load-bearing structure to at least one insulating layer.

[0027] Layers can be connected to each other in a complete manner or only partially, especially intermittently, and / or in a regular arrangement, such as by bonding.

[0028] For example, it can be specified that the load-bearing structure is connected to one or more insulation layers, either fully or only partially, especially intermittently, and / or in a regular arrangement, such as by bonding.

[0029] The connecting layer may be, for example, part of the load-bearing structure and / or part of the insulation layer, or a layer independent of it.

[0030] Further alternatively or additionally, the connecting layer may be an adhesive layer and / or a cohesive layer, such that the supporting structure and at least one insulating layer are preferably connected to each other by the attractive forces between similar particles within the material and / or by the attractive forces at the interface between two different materials, such as the material of the supporting structure and the material of the insulating layer. Therefore, according to this embodiment, a separate connecting layer is preferably not arranged between the supporting structure and the corresponding insulating layer. More precisely, the connecting layer is a transition region or boundary region between adjacent portions or layers.

[0031] By selecting at least one suitable insulating layer, various protection or isolation requirements can be considered in an advantageous manner.

[0032] In this way, for example, the influence of climate and / or mechanical and / or physical and / or chemical and / or mechanical factors can be addressed by adapting the protective element to the corresponding load through different insulation layers.

[0033] Advantageously, it can at least reduce or completely avoid damage to the device's (functionality).

[0034] In an implementation, the load-bearing structure includes or is formed of one or more load-bearing layers.

[0035] In particular, the load-bearing structure may include one or more metal layers.

[0036] Multiple load-bearing layers, especially multiple metal layers, preferably provide protection against mechanical loads and / or foreign object intrusion (into the protective element and / or device) and / or thermal loads and / or electromagnetic loads.

[0037] For example, thermal breakdown of the battery cell can cause components and / or protective elements of the device to become charged. Therefore, at least a portion of the protective elements is preferably configured to be conductive.

[0038] It can be advantageous for the support structure and / or layers arranged on the side of the support structure opposite to the battery cell, such as insulating layers, to be constructed as conductive layers or include such conductive layers. Thus, potential buildup can be avoided, particularly by immediate conduction and / or grounding.

[0039] For example, it can be specified that the conductivity of the load-bearing structure and / or layer is achieved by using conductive particles.

[0040] In alternative design options, the load-bearing structure may include one or more layers of timber.

[0041] Advantageously, multiple load-bearing layers can be connected to each other, for example, bonded to each other to form a load-bearing structure and / or connected to each other by the aforementioned adhesive forces and / or cohesive forces.

[0042] Preferably, the load-bearing structure extends entirely or partially along the length and / or surface of the protective element.

[0043] According to the preferred design, the load-bearing structure can be electrically isolated at its ends.

[0044] Advantageously, the protective element may include multiple insulating layers. These multiple insulating layers can be arranged, in particular, on both sides of the load-bearing structure.

[0045] This can improve the protective or insulating effect of the protective element. This type of design is within the scope of this application and, due to its multi-layered construction, can also be referred to as a multi-layered composite.

[0046] Particularly preferably, the multiple insulating layers differ from each other in their insulating properties. In particular, the multiple insulating layers differ in their thermal and / or electrical and / or electromagnetic and / or mechanical insulating properties.

[0047] However, different isolation properties are not limited to those mentioned above. More precisely, other isolation properties can be envisioned, such as physical and / or chemical isolation properties and / or any application-specific isolation properties.

[0048] For example, at least one of the multiple insulating layers preferably has a thermal insulating function, while at least one other of the multiple insulating layers preferably has an electrical insulating function.

[0049] With this type of design, the protective element can be preferably adapted to, for example, pre-defined (isolation) requirements.

[0050] In this embodiment, preferably, exactly one connecting layer is arranged between each of the multiple insulating layers. Therefore, the protective element can have a total of multiple connecting layers, which preferably improves the mechanical bonding strength of the protective element.

[0051] It is also advantageous that at least one insulating layer has a thickness in the range of 0.01 mm to 1 mm, particularly in the range of 0.05 mm and 0.8 mm, and particularly in the range of 0.2 mm to 0.6 mm.

[0052] If the protective element has multiple insulating layers, the multiple insulating layers can have the same thickness, or alternatively, have different thicknesses.

[0053] Furthermore, it may be advantageous for at least one insulating layer to have a partially different thickness and / or structured surface.

[0054] According to alternative implementations, preferably all insulating layers have partially different thicknesses and / or structured surfaces.

[0055] The term "structured surface" within the scope of this application can be understood as, for example, a bumpy and / or grooved surface. This type of structured surface can, for example, cause surface enlargement and thus advantageously produce an effective insulating surface.

[0056] Preferably, at least one insulating layer may comprise a coating or a single insulating layer.

[0057] In particular, at least one insulating layer may be a coating or a single insulating layer.

[0058] Alternatively, at least one insulating layer may preferably comprise or be formed of a plurality of individual insulating layers. The plurality of individual insulating layers may be bonded together, for example, to form an insulating layer.

[0059] In the implementation, the protective element is arranged at least on or in a portion of the device.

[0060] Particularly preferably, the protective element is arranged at least partially on the outer or inner side of the wall of the device.

[0061] According to alternative embodiments, the protective element can preferably also be arranged between two components of the device, especially the energy storage device. For example, the protective element can be arranged inside the battery (box) between two battery cells.

[0062] This is advantageous because protective elements can be precisely positioned at locations where the device should or must be protected.

[0063] According to other embodiments, at least one insulating layer partially surrounds the load-bearing structure.

[0064] In an alternative embodiment, at least one insulating layer preferably completely surrounds the load-bearing structure.

[0065] In particular, the load-bearing structure can also be advantageously protected by at least one insulating layer by completely surrounding it with at least one insulating layer.

[0066] It is also advantageous that the load-bearing structure includes or is formed of metal.

[0067] For example, load-bearing structures may include stainless steel and / or aluminum and / or metal alloys.

[0068] The advantage in this case is that the load-bearing structure obtains sufficient mechanical stability, and thus can protect the protective elements and thereby protect the device from mechanical loads.

[0069] In addition, the thermal conductivity of metals is advantageous in that it can disperse localized heating of the load-bearing structure.

[0070] In alternative design options, the load-bearing structure may include wood and / or plastic or be formed of wood and / or plastic.

[0071] Compared to metal load-bearing structures, load-bearing structures made of wood can achieve lighter load-bearing structures.

[0072] However, the materials used in load-bearing structures are not limited to the aforementioned metals, wood, and / or plastics. Rather, any suitable material can be considered for load-bearing structures.

[0073] The term "material" as appropriate within the scope of this application can be understood as a material that generally meets the requirements for a load-bearing structure and, for example, provides mechanical stability to the protective element and / or imparts thermal and / or electromagnetic insulation to the protective element.

[0074] Advantageously, at least one insulating layer comprises or is formed of a thermally insulating material.

[0075] For example, at least one insulating layer comprises silicate fiber and / or thermal insulating paper and / or glass fabric and / or ceramic fiber pad and / or heat-resistant plastic foam and / or heat-resistant paint or is formed from such materials.

[0076] Furthermore, in the embodiments, the insulating layer may include insulating paper or be formed of insulating paper.

[0077] More preferably, at least one insulating layer may comprise an intumescent material.

[0078] The term "expandable material" can be understood within the scope of this application as a material whose volume increases and density decreases accordingly under thermal conditions. For example, an expandable material can form a foamed ash layer that blocks the supply of oxygen and thus prevents the spread of flame.

[0079] Particularly preferably, the outermost insulating layer of the protective element may comprise or be formed of an intumescent material. This embodiment ensures that the insulating layer comprising the intumescent material is first exposed to heat, for example, in the event of a combustion event, and thus can optimally perform its protective or insulating function.

[0080] Non-limiting examples of expanding materials include:

[0081] - Water-based expandable materials,

[0082] - Solvent-based expandable materials, or

[0083] - Epoxy-based expanding materials.

[0084] In particular, the thermal properties of expandable materials are determined by their chemical composition. Particularly suitable expandable materials include, for example, water-soluble alkali metal silicate binders. This type of material preferably has a silica content of up to 96% and / or an N-octyl-2-pyrrolidone content in the range of 0.1% to 1%.

[0085] In addition, it is advantageous that the expanding material includes additives.

[0086] Additives can include, for example, thermal insulating materials, especially aerogels, or be formed from thermal insulating materials, especially aerogels. This type of thermal insulating material has low thermal conductivity and is typically certified in ways such as the UL94 flame test. Therefore, by constructing the additive as a thermal insulating material, the thermal protection of the insulating layer can be improved. In addition to the thermal protection provided by the aerogel, it also provides protection against electrical breakdown, thus improving electrical resistance when using aerogels.

[0087] Suitable aerogels are, for example, hydrophilic and synthetic highly amorphous silicate solids. This type of aerogel has, for example, a particle size in the range of 1 to 70 µm, preferably in the range of 1 to 20 µm, and particularly in the range of 10 to 15 µm. Furthermore, these aerogels have pore sizes in the range of 1 to 50 nm, preferably in the range of 10 to 30 nm, and particularly in the range of 15 to 25 nm. The thermal conductivity of this type of aerogel has values ​​in the range of 0.025 to 0.03 W / (mK).

[0088] To further enhance the mechanical resistance of the insulating layer, it may be beneficial to use additives including fibers, especially glass fibers and / or metal fibers and / or metal alloy fibers and / or ceramic fibers or formed thereof.

[0089] Alternatively or as a supplement, nonwoven or woven fabrics made of the aforementioned materials may be used to replace or supplement the fibers.

[0090] However, the additives mentioned above are not limited to use with or in expanding materials. More precisely, the additives may also be included in one or more of the materials listed in this application for the insulating layer and / or the connecting layer.

[0091] It may be particularly advantageous that at least one insulating layer and / or at least one load-bearing structure, especially at least one load-bearing layer, comprises or is formed of at least one high-temperature stable alloy according to formula (I).

[0097] The chemical elements that X and Z can represent are optional.

[0098] If only one chemical element X exists, or if multiple chemical elements X exist but chemical element Z is missing, then equation (I) can be MCrAlX.

[0099] If only one chemical element Z exists, or if only multiple chemical elements Z exist but chemical element X is missing, then equation (I) can also be MCrAlZ.

[0100] If chemical elements X and Z are missing, then formula (I) can be MCrAl.

[0102] It is particularly desirable that M represents the chemical element Ni.

[0103] X can preferably represent the chemical element Y.

[0104] Z preferably includes at least one of the chemical elements Ta, Mo, W, C, B, Zr, Nb, and Hf.

[0105] The mass fraction of the chemical element Cr can be advantageously 2 to 55% by weight, preferably 4 to 45% by weight, particularly preferably 6 to 40% by weight, for example 10 to 30% by weight.

[0106] The mass fraction of the chemical element Al can be advantageously 1 to 35% by weight, preferably 1.5 to 28% by weight, particularly preferably 1.5 to 18% by weight, for example 2 to 10% by weight.

[0107] The mass fraction of one or more optional chemical elements represented by X can advantageously be up to 5% by weight, preferably 0.01 to 4% by weight, particularly preferably 0.02 to 3% by weight, for example 0.03 to 3% by weight. If X represents more than one chemical element among chemical elements Y, Si, or Ti, then the multiple chemical elements represented by X are included in the calculation of the mass fraction.

[0108] The mass fraction of one or more chemical elements represented by Z can advantageously be up to 18% by weight, preferably from 0.001 to 18% by weight, and particularly preferably from 0.02 to 15% by weight. If Z represents more than one chemical element, then the multiple chemical elements represented by Z are included in the calculation of the mass fraction.

[0109] The mass fraction of one or more chemical elements represented by M can be advantageously 8 to 97% by weight, preferably 20 to 95% by weight, and particularly preferably 45 to 93% by weight. If M represents more than one chemical element, the multiple chemical elements represented by M are included in the calculation of the mass fraction.

[0110] According to the embodiments, the multiple insulating layers may also include or be formed of thermal insulating materials of the type described above.

[0111] This type of insulating layer preferably improves the thermal insulation of the protective elements and provides protection, for example, in the event of thermal runaway of the battery cells of the device, which is configured as an energy storage device.

[0112] However, thermal insulation materials are not limited to those listed above. More precisely, other materials that preferably have thermal insulation properties can also be considered.

[0113] In terms of electrical isolation, it is also advantageous that at least one insulating layer comprises or is formed of an electrical insulating material.

[0114] For example, at least one insulating layer comprises or is formed of a plastic and / or ceramic and / or plastic film or a material of this type.

[0115] In terms of electrical insulation, when an expanding material is used in one or more insulation layers, the expanding material may also include additives, which preferably include ceramic particles or are formed from ceramic particles.

[0116] According to the implementation, the multiple insulating layers may also include or be formed of electrical insulating materials of the type mentioned above.

[0117] However, the electrical insulating material is not limited to the materials listed above. More precisely, other materials that preferably have electrical insulating properties can also be considered.

[0118] Ceramic-based coatings and / or water-based coatings and / or glass-based coatings and / or epoxy-based coatings and / or powder coatings are particularly preferred.

[0119] Advantageously, ceramic-based coatings can form or have thermal and / or electrical insulation and / or mechanical robustness enhancement.

[0120] For example, ceramic-based coatings can provide protection against particle impact in the event of thermal runaway. The ceramic coatings are preferably resistant to temperatures of 1000°C or higher.

[0121] Water-based coatings can be, for example, polymer coatings.

[0122] For example, glass-based coatings can improve the physical and / or chemical resistance of protective elements, and thereby improve the physical and / or chemical resistance of the device.

[0123] Epoxy coatings can be, for example, two-component epoxy coatings. This type of coating preferably provides protection against moisture and / or chemicals and / or dirt and / or dust.

[0124] Alternatively or additionally, the coating may preferably also include or be formed of paint. Paint may, for example, be flame-retardant paint and / or anti-corrosion paint and / or electrical insulating paint.

[0125] Advantageously, it can be applied by brushing and / or rolling and / or spraying and / or dipping.

[0126] Furthermore, it is advantageous for the coating to include or be formed of intumescent materials, particularly those of the type already described above. Coatings of this type made from intumescent materials have proven advantageous because they enable the achievement of thin, lightweight yet highly resistant insulation.

[0127] Furthermore, according to embodiments, at least one insulating layer may comprise or be formed of a mechanically robust material. For example, at least one insulating layer may comprise or be formed of a fiber-reinforced composite material.

[0128] In an embodiment, at least one bonding layer comprises or is formed of an adhesive.

[0129] In particular, the adhesive can be advantageously a ceramic-based adhesive, a water-based adhesive, a glass-based adhesive, and / or an epoxy-based adhesive.

[0130] Through the feasibility of various design schemes of the adhesive with at least one connecting layer, the connecting layer can, in addition to its function of connecting the load-bearing structure and at least one insulating layer to each other, also preferably function in a thermal and / or electrical and / or electromagnetic and / or moisture-proof manner, and thus advantageously improve the overall protective effect of the protective element.

[0131] According to an embodiment, at least one bonding layer may include an adhesive or be formed from an adhesive.

[0132] In particular, the adhesive can be an acrylate-based adhesive.

[0133] Particularly preferably, the adhesive may be an adhesive tape, especially an adhesive tape that is bonded on both sides.

[0134] Another advantage is that the adhesive has a reinforcing structure. This type of reinforcing structure can be, for example, a fabric structure and / or a scaffold-like reinforcement, for example, made of plastic.

[0135] Specifically, the purpose of the device is achieved by means of a device, especially an electrical energy storage device, which includes protective elements of the aforementioned type.

[0136] According to the implementation, the device may preferably be one or more of the following exemplary devices:

[0137] - Housing; and / or

[0138] - Module overlays; and / or

[0139] - Battery cover; and / or

[0140] - Electrical energy storage devices; and / or

[0141] - Battery cells.

[0142] Furthermore, in embodiments, protective elements may also be arranged between two cells of the device, particularly between two battery cells. Thus, the protective elements advantageously form an inter-cell insulation, particularly to prevent or at least mitigate the spread of heat escape to adjacent cells. This arrangement of the protective elements and / or, with appropriate selection of the material for at least one insulating layer, can, for example, address additional requirements regarding compressibility and / or mechanical alternating loads and / or heat distribution between and / or within the two cells of the device.

[0143] Alternatively, the device can also be a component in an internal combustion engine environment. Attached Figure Description

[0154] Figure 9 A schematic cross-sectional view of the ninth embodiment of the protective element is shown.

[0155] In all the accompanying drawings, the same or functionally equivalent elements are given the same reference numerals. Detailed Implementation

[0156] refer to Figure 1 A schematic diagram of a cross-section of the protective element 100 according to the first embodiment is shown.

[0157] The illustrated embodiment of the protective element 100 also represents the simplest embodiment.

[0158] The protective element 100 is used to be arranged on or in the device 102. For simplicity, the device 102 is shown only as a shaded rectangle in the figure.

[0159] Device 102 is preferably the housing of an energy storage device, particularly of this type. Alternatively, device 102 may be, for example:

[0160] - Module overlays; and / or

[0161] - Battery cover; and / or

[0162] - Electrical energy storage devices; and / or

[0163] - Battery cells.

[0164] Furthermore, it can be envisioned that device 102 is a component in an internal combustion engine environment.

[0165] The protective element 100 is particularly used for the protective device 102, and particularly for the wall portion of the protective device or adjacent elements to be protected.

[0166] The protective element 100 may preferably extend entirely along the length and / or surface of the device 102, such that the protective element 100 completely surrounds the device 102.

[0167] Alternatively, the protective element 100 may extend only partially along the length and / or surface of the device 102, such that only a portion of the device 102 is covered by the protective element 100.

[0168] The protective element 100 includes a load-bearing structure 104. According to... Figure 1 In some embodiments, the load-bearing structure 104 is configured as a load-bearing layer. Within the scope of this application, the term "layer" can be understood as the geometry of a corresponding component whose longitudinal span or surface span is greater than its height span or thickness, for example at least about 5 times, and particularly at least about 20 times.

[0169] Alternatively (however, not shown), the load-bearing structure 104 may also include multiple load-bearing layers.

[0170] The load-bearing structure 104 may also include metal or preferably be formed of metal.

[0171] Particularly preferably, the load-bearing structure 104 is formed of a solid material, that is, it is formed of a dense body of a material, such as stainless steel or aluminum.

[0172] Thus, the support structure 104 advantageously forms a core of the protective element 100, which provides mechanical and / or thermal protection due to the materials used.

[0173] The load-bearing structure 104 preferably stabilizes the protective element 100. Furthermore, the load-bearing structure 104 preferably protects one or more insulating layers 106 from mechanical and / or thermal and / or chemical loads.

[0174] According to the embodiments, the load-bearing structure 104 may comprise wood and / or plastic or be formed from such materials. This has proven particularly advantageous in reducing the weight of the load-bearing structure 104.

[0175] The supporting structure 104 preferably extends over the entire surface of the device 102, i.e., over its entire width and / or length. This is in Figure 1 As shown in the image.

[0176] Alternatively, the support structure 104 may preferably extend only partially on or along the device 102, such that only a portion of the device 102 is covered by the support structure 104. This is described below. Figures 2 to 9 The diagram is used to illustrate this.

[0177] In addition, the protective element 100 has an insulating layer 106. The insulating layer 106 is used to protect, and in particular isolate, the device 102.

[0178] Therefore, the insulating layer 106 is specifically configured as an electrical and / or thermal and / or electromagnetic insulating part of the device 102 or forms such an insulating part.

[0179] The insulating layer 106 may, for example, comprise or be formed of a thermal insulating material. Non-limiting examples of this type of thermal insulating material include silicate fibers and / or thermal insulating paper and / or glass fabric and / or ceramic fiber pads.

[0180] Alternatively or additionally, the insulating layer 106 may preferably comprise or be formed of an electrically insulating material. Non-limiting examples of electrically insulating materials include plastic and / or ceramic and / or plastic films.

[0181] By employing ceramic as the material for the insulating layer 106, thermal insulation and / or mechanical robustness enhancement are achieved, in addition to electrical insulation. Mechanical robustness enhancement has proven particularly advantageous in cases of particle impact, such as thermal runaway.

[0182] Alternatively or additionally, the insulating layer 106 may include an electromagnetic insulator material. Non-limiting examples of electromagnetic insulator materials are ferromagnetic materials, such as Mu metal.

[0183] The insulating layer 106 preferably has a thickness in the range of 0.01 mm to 1 mm, particularly in the range of 0.05 mm and 0.8 mm, and particularly in the range of 0.2 mm to 0.6 mm.

[0184] For example, the thickness of the insulating layer 106 can vary depending on the material used and / or the required insulating properties.

[0185] To connect the load-bearing structure 104 and the insulating layer 106, the protective element 100 includes a connecting layer 108a.

[0186] The connecting layer 108a may be, for example, an adhesive layer that bonds the load-bearing structure 104 and the insulating layer 106 together with an adhesive.

[0187] Preferably, the bonding layer 108a may include or be formed of an adhesive. In particular, the adhesive is a ceramic-based adhesive.

[0188] Additionally, this type of ceramic-based adhesive preferably provides electrical and / or thermal insulation, and thus preferably improves the overall thermal and / or electrical insulation performance of the protective element 100.

[0189] According to other embodiments, the adhesive is preferably a glass-based adhesive. This type of adhesive has also proven advantageously suitable in terms of its electrical and / or thermal insulation properties.

[0190] In alternative embodiments, it may be advantageous to use an epoxy-based adhesive. Epoxy-based adhesives have the advantage of resistance to alkalis and / or acids and / or solvents.

[0191] According to other embodiments, the adhesive is preferably a water-based adhesive.

[0192] Therefore, as already mentioned, the possibility of changing the material of the connecting layer 108a makes it possible to adapt to the proposed protection requirements in a simple manner, which advantageously improves the overall protective function of the protection element 100 and makes it adaptable.

[0193] In addition, the protection element 100 can also be like Figure 1 The optional connecting layer 108b is arranged on the outer side 110 of the wall portion 112 of the device 102 via a connecting layer 108b. Figure 1 It is shown only by dashed lines.

[0194] Therefore, the load-bearing structure 104 is connected to the device 102 on one side via the connecting layer 108b, and to the insulating layer 106 on the other side via the connecting layer 108a.

[0195] The load-bearing structure 104, the connecting layer 108a arranged between the load-bearing structure 104 and the insulating layer 106, and the insulating layer 106 form a protective element 100.

[0196] Alternatively, the protective element 100 may be arranged on the inner side 114 of the wall portion 112 of the device 102.

[0197] Furthermore, in embodiments not shown, it is conceivable that the protective element 100 is arranged both on the inner side 114 of the wall portion 112 and on the outer side 110 of the wall portion 112.

[0198] Alternatively, the protective element 100 can also be mounted in other ways, such as screwed onto the device 102. To illustrate this embodiment, in Figure 1The connection layer 108b, which is arranged between the device 102 and the supporting structure 104, is shown only by dashed lines.

[0199] Therefore, when viewed in the image plane toward the device 102, the protective element 100 has the following structure: an insulating layer 106, a connecting layer 108a, a load-bearing structure 104, and (optionally) a connecting layer 108b.

[0200] Furthermore, all layers 104, 106, 108a, and 108b extend along the entire length and / or surface of the protective element 100. Alternatively, however, it may be conceivable that one or more of the aforementioned layers 104, 106, 108a, and 108b extend only partially along the length and / or surface of the protective element 100.

[0201] exist Figure 2 The image shows a second embodiment of the protective element 100 according to the present invention.

[0202] As can be seen from the cross-section shown, the protective element 100 also has a load-bearing structure 104.

[0203] In addition, according to Figure 1 The protective element 100 is different, according to Figure 2 The protective element 100 has two insulating layers 106a and 106b.

[0204] Preferably, the two insulating layers 106a and 106b differ from each other in their insulating properties. In particular (however, not limitingly), the two insulating layers 106a and 106b may differ in their thermal and / or electrical and / or electromagnetic insulating properties. Differences in their mechanical protection capabilities, robustness, and / or resistance are also conceivable.

[0205] As a non-limiting example, one of the two insulating layers 106a and 106b may be configured as an electrical insulating layer for electrical isolation, while the other insulating layer 106a and 106b may be configured as a thermal insulating layer for thermal isolation.

[0206] Therefore, the protective element 100 constructed in this way preferably provides electrical and thermal protection or electrical and thermal isolation.

[0207] However, other combinations of different insulating materials and insulating properties can also be envisioned, so that the protective element 100 can be adapted individually.

[0208] Insulation layers 106a and 106b are connected to the load-bearing structure 104 via connecting layers 108a and 108b. For example, from... Figure 2It is understood that the insulating layers 106a and 106b are arranged on both sides of the load-bearing structure 104: a corresponding connecting layer 108a and 108b connects one of the insulating layers 106a and 106b to the corresponding side of the load-bearing structure 104.

[0209] Furthermore, the protective element 100 is arranged on the device 102 via the connecting layer 108c. According to... Figure 2 In some embodiments, the connection layer 108c is also part of the protective element 100.

[0210] Therefore, when viewed in the image plane toward the device 102, the protective element 100 has the following structure: an insulating layer 106b, a connecting layer 108a, a load-bearing structure 104, a connecting layer 108b, an insulating layer 106a, and a connecting layer 108c.

[0211] Furthermore, all layers 104, 106a, 106b, 108a, 108b, and 108c extend along the entire length and / or surface of the protective element 100. Alternatively, however, it may be conceivable that one or more of the aforementioned layers 104, 106a, 106b, 108a, 108b, and 108c extend only partially along the length and / or surface of the protective element 100.

[0212] As from Figure 2 It is understood that the protective element 100 does not extend across the entire surface of the device 102. More precisely, the protective element 100 is arranged only in a portion of the device 102.

[0213] In addition, layers 104, 106a, 106b, 108a, 108b, and 108c may have different thicknesses and / or structured surfaces.

[0214] In addition, the protective element 100 Figure 2 The illustrated embodiments are similar to those in terms of their functionality and / or mode of operation and / or their modular construction capabilities. Figure 1 The embodiments shown are consistent, and therefore reference can be made to the above description thereof.

[0215] refer to Figure 3 The third embodiment of the protective element 100 according to the present invention is shown in cross section.

[0216] The protective element 100 also has a load-bearing structure 104.

[0217] In addition, the protective element 100 has two insulating layers 106a and 106b. The insulating layers 106a and 106b are preferably arranged on both sides of the supporting structure 104, that is, the insulating layer 106a is on one side of the supporting structure 104, and the insulating layer 106b is on the other side of the supporting structure 104.

[0218] The two insulating layers 106a and 106b are connected to the load-bearing structure 104 via connecting layers 108a and 108b, respectively.

[0219] According to Figure 3 In this embodiment, the two insulating layers 106a and 106b comprise the same insulating material. This is in Figure 3 The same shading is used to illustrate this in a diagrammatic way.

[0220] For example (however, not limiting), the two insulating layers 106a, 106b comprise electrically insulating materials. This preferably improves the electrical insulating performance of the protective element 100.

[0221] In the alternative design, both insulation layers 106a and 106b include thermal insulation material.

[0222] According to other embodiments, both insulating layers 106a and 106b include electromagnetic insulating materials.

[0223] Therefore, when viewed in the image plane toward the device 102, the protective element 100 has the following structure: an insulating layer 106b, a connecting layer 108a, a load-bearing structure 104, a connecting layer 108b, an insulating layer 106a, and a connecting layer 108c.

[0224] Furthermore, all layers 104, 106a, 106b, 108a, 108b, and 108c extend along the entire length and / or surface of the protective element 100. Alternatively, however, it may be conceivable that one or more of the aforementioned layers 104, 106a, 106b, 108a, 108b, and 108c extend only partially along the length and / or surface of the protective element 100.

[0225] In addition, layers 104, 106a, 106b, 108a, 108b, and 108c may have different thicknesses and / or structured surfaces.

[0226] In addition, the protective element 100 Figure 3 The illustrated embodiments are similar to those in terms of their functionality and / or mode of operation and / or their modular construction capabilities. Figure 1 and Figure 2 The embodiments shown are consistent, and therefore reference can be made to the above description thereof.

[0227] exist Figure 4 The fourth embodiment of the protective element 100 according to the present invention is shown in cross section.

[0228] Similar to the already described protective element 100, the protective element 100 according to the fourth embodiment also has a support structure 104. Likewise, according to... Figure 4 The load-bearing structure 104 is preferably constructed as a load-bearing layer.

[0229] However, the protective element 100 according to the fourth embodiment includes three insulating layers 106a, 106b, and 106c.

[0230] Insulation layer 106c is arranged on one side of the load-bearing structure 104 via connecting layer 108a. Similarly, insulation layer 106b is arranged on the other side of the load-bearing structure 104 via other connecting layers 108b. Therefore, according to... Figure 4 The load-bearing structure 104 has insulation layers 106b and 106c on both sides.

[0231] Viewed in the image plane, other insulating layers 106a are arranged on the insulating layer 106b facing the device 102 via the connecting layer 108c.

[0232] The additional insulating layer 106a is preferably arranged on the device 102 by means of a connecting layer 108d, and in particular on the outer side 110 of the wall portion 112 of the device 102.

[0233] Alternative sites, according to Figure 4 The protective element 100 can also be arranged on the inner side 114 of the wall portion 112 or on both sides of the wall portion 112.

[0234] Therefore, in general, the protective element 100 according to the fourth embodiment has a load-bearing structure 104, three insulating layers 106a, 106b, 106c and four connecting layers 108a, 108b, 108c, 108d.

[0235] Therefore, when viewed in the image plane toward the device 102, the protective element 100 has the following structure: an insulating layer 106c, a connecting layer 108a, a load-bearing structure 104, a connecting layer 108b, an insulating layer 106b, a connecting layer 108c, an insulating layer 106a, and a connecting layer 108d.

[0236] Furthermore, all layers 104, 106a, 106b, 106c, 108a, 108b, 108c, and 108d extend along the entire length and / or surface of the protective element 100. Alternatively, however, it may be conceivable that one or more of the aforementioned layers 104, 106a, 106b, 106c, 108a, 108b, 108c, and 108d extend only partially along the length and / or surface of the protective element 100.

[0237] In addition, layers 104, 106a, 106b, 106c, 108a, 108b, 108c, and 108d may have different thicknesses and / or structured surfaces.

[0238] In addition, the protective element 100 Figure 4The illustrated embodiments are similar to those in terms of their functionality and / or mode of operation and / or their modular construction capabilities. Figures 1 to 3 The embodiments shown are consistent, and therefore reference can be made to the above description thereof.

[0239] Reference of the protective element 100 according to the present invention Figure 5 The fifth embodiment shown is also arranged on the device 102.

[0240] Similar to the protective element 100 described above, according to Figure 5 The protective element 100 also has a load-bearing structure 104.

[0241] However, the load-bearing structure 104 does not extend along the entire length of the protective element 100.

[0242] More precisely, compared to the previously described embodiments, the support structure 104 is also surrounded by a connecting layer 108b on its end face.

[0243] Therefore, in this embodiment, the supporting structure 104 is completely surrounded by the connecting layers 108a, 108b, and 108c.

[0244] The protective element 100 is mounted on the device 102, particularly on the outer side 110 of the wall portion 112 of the device 102, via other connecting layers 108d with insulating layers 106a.

[0245] This type of design, with a fully enclosed load-bearing structure 104, can prove advantageous, especially when the protective element 100 is only partially arranged on or within the device 102.

[0246] Since the end face of the support structure 104 is surrounded by the connecting layer 108b, it is preferable that an insulating portion is also formed on the end face of the support structure 104. This is especially true if the connecting layer 108b preferably comprises an adhesive having insulating properties of the type already described.

[0247] Therefore, when viewed in the image plane toward the device 102, the protective element 100 has the following structure: an insulating layer 106b, a connecting layer 108a, a load-bearing structure 104 surrounded by the connecting layer 108b, a connecting layer 108c, an insulating layer 106a, and a connecting layer 108d.

[0248] In addition, layers 104, 106a, 106b, 108a, 108b, 108c, and 108d may have different thicknesses and / or structured surfaces.

[0249] In addition, the protective element 100 Figure 5 The illustrated embodiments are similar to those in terms of their functionality and / or mode of operation and / or their modular construction capabilities. Figures 1 to 4 The embodiments shown are consistent, and therefore reference can be made to the above description thereof.

[0250] refer to Figure 6 A cross-section of the sixth embodiment of the protective element 100 is shown.

[0251] In terms of construction, according to Figure 6 The protective element 100 also has a load-bearing structure 104. The load-bearing structure 104 is preferably constructed as a load-bearing layer.

[0252] Compared to the already described protective element 100, Figure 6 The protective element 100 shown has an insulating layer 106b configured as a coating. This insulating layer 106b is arranged, and in particular applied, to the load-bearing structure 104.

[0253] Preferably, the insulating layer 106b configured as a coating is thinner than the insulating layer 106 configured as a single insulating layer.

[0254] The protective element 100 can preferably be designed to be thinner overall, without advantageously sacrificing or reducing its insulating properties.

[0255] According to Figure 6 In one embodiment, the insulating layer 106b, configured as a coating, is arranged directly, preferably without the connecting layer 108, and is applied, in particular, to the load-bearing structure 104.

[0256] In addition, the protective element 100 also has an insulating layer 106a, which is constructed as a single insulating layer. A connecting layer 108a is disposed between the insulating layer 106a and the load-bearing structure 104, and the insulating layer 106a is connected to the load-bearing structure 104 through the connecting layer.

[0257] Preferably, the insulating layer 106b, which is configured as a coating, and the insulating layer 106a, which is configured as a single insulating layer, differ in their insulating properties. In particular, the two insulating layers 106a and 106b differ in their thermal and / or electrical and / or electromagnetic insulating properties.

[0258] Similar to the already illustrated embodiments, according to Figure 6 The protective element 100 is arranged on the device 102 as a single insulating layer 106a. For this purpose, a connecting layer 108b is preferably arranged between the insulating layer 106a and the device 102 for connection.

[0259] Therefore, when viewed in the image plane toward the device 102, the protective element 100 has the following structure: an insulating layer 106b with a coating, a support structure 104, a connecting layer 108a, an insulating layer 106a, and a connecting layer 108b.

[0260] Furthermore, all layers 104, 106a, 106b, 108a, and 108b extend along the entire length and / or surface of the protective element 100. Alternatively, however, it may be conceivable that one or more of the aforementioned layers 104, 106a, 106b, 108a, and 108b extend only partially along the length and / or surface of the protective element 100.

[0261] In addition, layers 104, 106a, 106b, 108a, and 108b may have different thicknesses and / or structured surfaces.

[0262] In addition, the protective element 100 Figure 6 The illustrated embodiments are similar to those in terms of their functionality and / or mode of operation and / or their modular construction capabilities. Figures 1 to 5 The embodiments shown are consistent, and therefore reference can be made to the above description thereof.

[0263] In a seventh embodiment of the protective element 100 according to the invention, the protective element 100 is also connected to the device 102 via the connecting layer 108b.

[0264] In the illustrated embodiment, the protective element 100 is arranged on the outer side 110 of the wall portion 112 of the device 102. However, alternatively or additionally, the protective element 100 may also be arranged on the inner side 114 of the wall portion 112 of the device 102.

[0265] According to this embodiment, the protective element 100 has a load-bearing structure 104.

[0266] The load-bearing structure 104 is connected to the insulating layer 106a on one side via a connecting layer 108a. The insulating layer 106a is preferably constructed as a single insulating layer.

[0267] As from Figure 7 It is understood that, in this embodiment, the support structure 104 also extends only partially along the protective element 100. Therefore, the support structure 104 does not extend over the entire length of the protective element 100.

[0268] The area of ​​the load-bearing structure 104 that is not connected to the connecting layer 108a is in accordance with Figure 7 In the embodiment, it is completely surrounded by the isolation layer 106b.

[0269] In particular, the insulating layer 106b is configured as a coating.

[0270] Therefore, the insulating layer 106b preferably also surrounds the end face of the supporting structure 104. Therefore, the supporting structure 104 is preferably completely surrounded by the insulating layer 106b and the connecting layer 108a.

[0271] The insulating layer 106b, constructed as a coating, can advantageously protect the load-bearing structure 104 from various influences, such as chemical and / or physical influences.

[0272] Alternatively or supplementally, the insulating layer 106b also provides an insulating effect and thus a protective effect, such that the device 102 is preferably also isolated and thus protected.

[0273] Particularly preferably, in this embodiment, the two insulating layers 106a and 106b also differ from each other in their insulating properties. In particular, the two insulating layers 106a and 106b differ in their thermal and / or electrical and / or electromagnetic insulating properties.

[0274] Therefore, when viewed in the image plane toward the device 102, the protective element 100 has the following structure: an insulating layer 106b, a load-bearing structure 104 surrounded by the insulating layer 106b, a connecting layer 108a, an insulating layer 106a, and a connecting layer 108b.

[0275] In addition, layers 104, 106a, 106b, 108a, and 108b may have different thicknesses and / or structured surfaces.

[0276] In addition, the protective element 100 Figure 7 The illustrated embodiments are similar to those in terms of their functionality and / or mode of operation and / or their modular construction capabilities. Figures 1 to 6 The embodiments shown are consistent, and therefore reference can be made to the above description thereof.

[0277] exist Figure 8 Other embodiments of the protective element 100 are shown in cross-section.

[0278] In this embodiment, the protective element 100 also has a support structure 104. The support structure 104 is preferably constructed as a support layer.

[0279] Connecting layers 108a and 108b are arranged on both sides of the load-bearing structure 104. Insulation layers 106a and 106b are connected to the load-bearing structure 104 through the connecting layers 108a and 108b, respectively.

[0280] Therefore, the load-bearing structure 104 has connecting layers 108a, 108b on each side and insulating layers 106a, 106b attached to and connected to the connecting layers 108a, 108b.

[0281] An additional insulating layer 106c is disposed on, and in particular applied, on the insulating layer 106b in the insulating layer. For this purpose, the additional insulating layer 106c is preferably constructed as a coating.

[0282] Particularly preferably, the additional insulating layer 106c is installed or applied directly, i.e. preferably without the connecting layer 108 located therebetween, onto the insulating layer 106b.

[0283] The insulating effect of the insulating layer 106b can be further enhanced by the additional insulating layer 106c. Alternatively or additionally, the additional insulating layer 106c can preferably also cover other insulating properties.

[0284] Therefore, for example, it can be envisioned that the insulating layer 106b is an electrical insulating layer for electrical isolation, and the additional insulating layer 106c is a thermal insulating layer for thermal isolation. Electrical and thermal isolation of the device 102 can be advantageously achieved through this type of insulating composite.

[0285] Additionally, in this embodiment, the insulating layer 106a may be configured, for example, as an electromagnetically insulating layer, such that the protective element 100 provides electrical, thermal, and electromagnetic isolation to the device 102 in this embodiment.

[0286] Therefore, device 102 can be protected by protective element 100 from electrical, thermal and electromagnetic influences.

[0287] In the illustrated embodiment, the protective element 100 is arranged on the outer side 110 of the wall portion 112 of the device 102. However, alternatively or additionally, the protective element 100 may also be arranged on the inner side 114 of the wall portion 112 of the device 102.

[0288] Therefore, when viewed in the image plane toward the device 102, the protective element 100 has the following structure: an insulating layer 106c, an insulating layer 106b, a connecting layer 108a, a load-bearing structure 104, a connecting layer 108b, an insulating layer 106a, and a connecting layer 108c, all of which are constructed as coatings.

[0289] Furthermore, all layers 104, 106a, 106b, 106c, 108a, 108b, and 108c extend along the entire length and / or surface of the protective element 100. Alternatively, however, it may be conceivable that one or more of the aforementioned layers 104, 106a, 106b, 106c, 108a, 108b, and 108c extend only partially along the length and / or surface of the protective element 100.

[0290] In addition, layers 104, 106a, 106b, 106c, 108a, 108b, and 108c may have different thicknesses and / or structured surfaces.

[0291] In addition, the protective element 100 Figure 8 The illustrated embodiments are similar to those in terms of their functionality and / or mode of operation and / or their modular construction capabilities. Figures 1 to 7The embodiments shown are consistent, and therefore reference can be made to the above description thereof.

[0292] Figure 9 An alternative design for the protection element 100 is shown. In this ninth embodiment, the protection element 100 is arranged between two devices 102. Device 102 may be, for example, a battery cell.

[0293] The protective element 100 is preferably arranged between the inner sides 114 of the wall portion 112 of the device 102.

[0294] This type of arrangement of the protective element 100 can isolate and protect the two devices 102, especially the two battery cells, from each other.

[0295] According to Figure 9 In one embodiment, the protective element 100 has a support structure 104.

[0296] The load-bearing structure 104 is preferably constructed as a load-bearing layer.

[0297] Connecting layers 108b and 108c are arranged on both sides of the load-bearing structure 104. On both sides of the load-bearing structure 104, insulating layers 106a and 106b are respectively attached to the two connecting layers 108b and 108c.

[0298] The two insulating layers 106a and 106b are connected to the load-bearing structure 104 via a connecting layer 108, particularly by adhesive bonding.

[0299] For connection with device 102, connecting layers 108a and 108d are also arranged on the side of insulating layers 106a and 106b away from the supporting structure 104.

[0300] One of the connecting layers 108a and 108d connects, in particular, adhesively connects the protective element 100 to a corresponding inner side 114 of the device 102.

[0301] Therefore, when viewed from bottom to top in the image plane, according to Figure 9 The protective element 100 has the following structure: a connecting layer 108a, an insulating layer 106b, a supporting structure 104, a connecting layer 108c, an insulating layer 106a, and a connecting layer 108d.

[0302] Preferably, the two insulating layers 106a and 106b differ from each other in their insulating properties, especially in their thermal and / or electrical and / or electromagnetic insulating properties.

[0303] For example, insulating layer 106a is configured as a thermal insulating layer. Another insulating layer 106b is configured as an electrical insulating layer in this case, for example.

[0304] This type of structure of the protective element 100 can advantageously provide electrical and thermal protection for the device 102.

[0305] Alternatively, according to the embodiment, the two insulating layers 106a and 106b may have the same insulating properties. Preferably, the protective element 100 here has a symmetrical structure with respect to the layers 106a, 106b, 108a, 108b, 108c, and 108d arranged on both sides of the supporting structure 104.

[0306] This type of protection can be advantageous, especially when a protective element 100 is used between two battery cells, to prevent the two battery cells from thermally and / or electrically affecting each other. For example, in the event of thermal runaway in one of the battery cells, the associated effects on the other battery cell can be reduced at least.

[0307] According to Figure 9 In the embodiments described, all layers 104, 106a, 106b, 108a, 108b, 108c, and 108d extend along the entire length and / or surface of the protective element 100. Alternatively, however, it may be conceivable that one or more of the aforementioned layers 104, 106a, 106b, 106c, 108a, 108b, 108c, and 108d extend only partially along the length and / or surface of the protective element 100.

[0308] In addition, layers 104, 106a, 106b, 108a, 108b, 108c, and 108d may have different thicknesses and / or structured surfaces.

[0309] In addition, the protective element 100 Figure 9 The illustrated embodiments are similar to those in terms of their functionality and / or mode of operation and / or their modular construction capabilities. Figures 1 to 8 The embodiments shown are consistent, and therefore reference can be made to the above description thereof.

[0310] However, the design of the insulating properties of the insulating layers 106, 106a, 106b, 106c mentioned above in all embodiments is not limited to the aforementioned insulating properties, and is not provided in only the mentioned combinations. More precisely, insulating layers 106, 106a, 106b, 106c with different insulating properties and / or thicknesses can preferably be combined arbitrarily with each other to enable the protective element 100 to be adapted to the corresponding requirements in an optimal and simple manner. For example, it is also conceivable that one or more insulating layers 106, 106a, 106b, 106c are constructed to be thermally insulating and simultaneously mechanically stable and thus able to withstand mechanical forces.

[0311] In other embodiments (not shown) of the protective element 100, one or more features and / or advantages of the embodiments mentioned above can be arbitrarily combined with each other. For example, in Figure 1 In the illustrated embodiment, the insulating layer 106 and / or the load-bearing structure 104 may also be partially or completely provided according to... Figure 7 The embodiment shown is constructed as an insulating layer 106b of the coating.
