Description

Technical Field

[0001] The present invention relates to the technical field of batteries, and in particular to a battery and an electrical device. Background Art

[0002] In the related technology, short circuits in battery cells can easily cause the battery to catch fire, resulting in significant economic losses and even life safety. Summary of the invention

[0003] The embodiment of the present invention provides a battery that can effectively prevent the battery from catching fire.

[0004] In a first aspect, an embodiment of the present invention provides a battery, comprising: a battery box having a storage space; a battery cell, the battery cell being arranged in the storage space and having a pressure relief portion; and an oxygen-consuming component, the oxygen-consuming component being arranged in the storage space and used to consume oxygen in the storage space when the pressure relief portion is in a pressure relief state.

[0005] In the above technical solution, an oxygen-consuming component is arranged in the accommodation space for accommodating the battery cell, and the oxygen-consuming component is used to consume the oxygen in the accommodation space when the pressure relief part is in the pressure relief state, so that the oxygen content in the accommodation space is reduced, so as to effectively suppress the fire caused by the pressure relief, and provide more time for property rescue and personnel escape in case of thermal runaway.

[0006] In some embodiments, the oxygen-consuming component includes an oxygen-consuming material, and the oxygen-consuming material includes a combination of one or more of red phosphorus, carbon powder, and cobalt crystals. In the above technical solution, the oxygen-consuming material reacts violently with oxygen, plays a role in rapidly consuming oxygen, and suppressing fire more timely and quickly.

[0007] In some embodiments, the oxygen-consuming part includes an oxygen-consuming material and an encapsulation layer for encapsulating the oxygen-consuming material, and the heat-resistant temperature of the encapsulation layer is lower than the temperature of the discharge of the pressure relief part. In the above technical solution, when the actual temperature is lower than the heat-resistant temperature of the encapsulation layer, the structure of the encapsulation layer remains intact, thereby maintaining the state of encapsulating the oxygen-consuming material to isolate the oxygen-consuming material from the air in the accommodation space, and maintaining the oxygen-consuming capacity of the oxygen-consuming material. When the actual temperature is greater than or equal to the heat-resistant temperature of the encapsulation layer, the structure of the encapsulation layer is destroyed, the oxygen-consuming material is exposed to the accommodation space and reacts with the oxygen in the accommodation space, thereby consuming the oxygen in the accommodation space.

[0008] In some embodiments, the heat resistance of the encapsulation layer is greater than or equal to 100° C. and less than or equal to 300° C. In the above technical solution, the heat resistance of the encapsulation layer is higher than the temperature of the battery under normal working conditions, so that the encapsulation layer is not easily damaged under normal working conditions, causing the oxygen-consuming material to fail; and the heat resistance of the encapsulation layer is not higher than the temperature of the emission when the battery cell is thermally runaway, so that the encapsulation layer can be quickly and timely damaged and release the oxygen-consuming material, thereby improving the timeliness and efficiency of oxygen consumption.

[0009] In some embodiments, the material of the encapsulation layer includes a plastic material. In the above technical solution, the plastic material has strong shape plasticity, so that the oxygen-consuming component can be easily formed into any desired shape to match the installation in the accommodation space, and the plastic material can be quickly damaged to release the oxygen-consuming material when encountering high-temperature emissions.

[0010] In some embodiments, the oxygen-consuming material is in powder or granular form. In the above technical solution, the oxygen-consuming material has a certain fluidity. After the encapsulation layer is damaged, the oxygen-consuming material inside can quickly flow outward through the damaged opening and disperse, thereby fully contacting with the oxygen in the accommodation space, which is conducive to improving the oxygen consumption efficiency.

[0011] In some embodiments, there are multiple battery cells, and the multiple battery cells constitute a row or multiple rows of battery packs arranged along a first direction. The battery pack includes multiple battery cells arranged along a second direction. The oxygen-consuming parts are arranged one-to-one with the battery packs. The oxygen-consuming parts extend along the second direction and are arranged relative to the pressure relief parts of the multiple battery cells of the same battery pack along a third direction. The first direction, the second direction and the third direction intersect with each other. In the above technical solution, when the pressure relief part sprays emissions outward during thermal runaway, the emissions can be accurately sprayed onto the oxygen-consuming parts, so that the oxygen-consuming parts can consume oxygen in time, improve oxygen consumption efficiency, and thus improve the effect of suppressing fire. And each pressure relief part will not be blocked by other battery cells when spraying emissions outward, and can trigger the oxygen-consuming parts to consume oxygen in time.

[0012] In some embodiments, the oxygen-consuming part includes a plurality of first oxygen-consuming parts arranged along the second direction and a second oxygen-consuming part connecting two adjacent first oxygen-consuming parts, the first oxygen-consuming part is opposite to the pressure relief part along the third direction, and the size of the first oxygen-consuming part along the third direction is larger than the size of the second oxygen-consuming part along the third direction. In the above technical solution, the size of the first oxygen-consuming part opposite to the pressure relief part is larger to meet the amount of oxygen that can be consumed by the first oxygen-consuming part under the pressure relief state of the pressure relief part, and the size of the second oxygen-consuming part is smaller, which can reduce the total amount of oxygen-consuming materials to a certain extent and reduce the cost of the oxygen-consuming part.

[0013] In some embodiments, the battery further includes: a wiring harness isolation plate, the wiring harness isolation plate is arranged in the accommodation space and is located on one side of the battery cell along the third direction, the oxygen-consuming parts are installed in the battery box, and the wiring harness isolation plate is provided with an avoidance hole that penetrates along the third direction and is used to avoid the oxygen-consuming parts. In the above technical solution, the oxygen-consuming parts are installed in the battery box, so that the space for installing the oxygen-consuming parts in the accommodation space is larger, and the shielding of the oxygen-consuming parts by the wiring harness isolation plate can be reduced or avoided, so that the emissions sprayed by the pressure relief part can be directly sprayed onto the oxygen-consuming parts, which is convenient for the oxygen-consuming parts to respond in time.

[0014] In some embodiments, the size of the oxygen-consuming component along the third direction is greater than or equal to 20 mm and less than or equal to 50 mm. In the above technical solution, the size of the oxygen-consuming component along the third direction is larger to meet the oxygen consumption requirement, and the size of the oxygen-consuming component along the third direction is not too large to cause position interference with other components or cause material waste.

[0015] In some embodiments, the oxygen-consuming component is bonded to the battery box; and / or, a first mounting groove is provided on a side of the battery box facing the wiring harness isolation plate, and the oxygen-consuming component is at least partially embedded in the first mounting groove. In the above technical solution, the oxygen-consuming component is connected to the battery box in a simple manner, and the fixation is firm and reliable, so that the oxygen-consuming component can be stably maintained in a position relative to the pressure relief part, so that oxygen consumption is timely and effective.

[0016] In some embodiments, the battery further comprises: a wiring harness isolation plate, the wiring harness isolation plate is arranged in the accommodation space and is located on one side of the battery cell along the third direction, and the oxygen-consuming component is installed on the wiring harness isolation plate. In the above technical solution, the wiring harness isolation plate is close to the battery cell, which is conducive to making the distance between the oxygen-consuming component and the pressure relief part closer, so that it can respond more quickly when the pressure relief part sprays emissions, start consuming oxygen more promptly, reduce the oxygen-consuming materials required to be consumed, and improve the effect of suppressing fire.

[0017] In some embodiments, the size of the oxygen-consuming component along the third direction is greater than or equal to 10 mm and less than or equal to 20 mm. In the above technical solution, the size of the oxygen-consuming component along the third direction is small, and it is not easy to cause position interference with other components, and the size of the oxygen-consuming component along the third direction is not too small to affect the fire suppression effect.

[0018] In some embodiments, the wiring harness isolation plate is provided with a second mounting groove on a side facing the battery cell, and the oxygen-consuming component is at least partially embedded in the second mounting groove; and / or the wiring harness isolation plate is bonded to the oxygen-consuming component. In the above technical solution, the oxygen-consuming component can be kept at a set position and opposite to the pressure relief portion, so that oxygen consumption is timely and effective.

[0019] In a second aspect, an embodiment of the present invention further provides an electrical device, comprising the above-mentioned battery, wherein the battery is used to provide electrical energy for the electrical device. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship.

[0044] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0045] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] The term "and / or" in the present invention is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in the present invention generally indicates that the associated objects before and after are in an "or" relationship.

[0047] In the embodiments of the present invention, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present invention shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary and should not constitute any limitation to the present invention.

[0048] The term "plurality" used in the present invention refers to two or more (including two).

[0049] In the present invention, a battery refers to a single physical module that includes one or more battery cells to provide a higher voltage and capacity. For example, the battery mentioned in the present invention may include a battery module or a battery pack. Some batteries may include a battery box for encapsulating one or more battery cells or multiple battery modules. The battery box can reduce or avoid the influence of liquid or other foreign matter on the charging or discharging of the battery cells. Of course, there are also some batteries that do not include the above-mentioned battery box and are directly set in the battery installation compartment of the electrical device. In other words, the battery installation compartment serves as the battery box of the battery.

[0050] In the present invention, the battery cell may include a lithium ion secondary battery, a lithium ion primary battery, a lithium sulfur battery, a sodium lithium ion battery, a sodium ion battery or a magnesium ion battery, etc., and the embodiments of the present invention are not limited thereto. The battery cell may be cylindrical, flat, rectangular or other shapes, etc., and the embodiments of the present invention are not limited thereto. Battery cells are generally divided into three types according to the packaging method: cylindrical battery cells, square battery cells and soft-pack battery cells, and the embodiments of the present invention are not limited thereto.

[0051] For example, a battery cell may include a housing, an electrode assembly and an electrolyte, wherein the housing is used to contain the electrode assembly and the electrolyte. The electrode assembly is composed of a positive electrode sheet, a negative electrode sheet and a separator. The battery cell mainly relies on the movement of metal ions between the positive electrode sheet and the negative electrode sheet to work. The positive electrode sheet includes a positive electrode collector and a positive electrode active material layer, wherein the positive electrode active material layer is coated on the surface of the positive electrode collector, and the positive electrode collector not coated with the positive electrode active material layer protrudes from the positive electrode collector coated with the positive electrode active material layer, and the positive electrode collector not coated with the positive electrode active material layer serves as a positive electrode ear. Taking a lithium-ion battery as an example, the material of the positive electrode collector may be aluminum, and the positive electrode active material may be lithium cobalt oxide, lithium iron phosphate, ternary lithium or lithium manganese oxide, etc.

[0052] The negative electrode sheet includes a negative electrode current collector and a negative electrode active material layer. The negative electrode active material layer is coated on the surface of the negative electrode current collector. The negative electrode current collector not coated with the negative electrode active material layer protrudes from the negative electrode current collector coated with the negative electrode active material layer. The negative electrode current collector not coated with the negative electrode active material layer serves as a negative electrode tab. The material of the negative electrode current collector can be copper, and the negative electrode active material can be carbon or silicon, etc. In order to ensure that a large current passes without melting, the number of positive electrode tabs is multiple and stacked together, and the number of negative electrode tabs is multiple and stacked together.

[0053] The material of the separator may be PP (polypropylene) or PE (polyethylene), etc. In addition, the electrode assembly may be a winding structure or a stacked structure, but the embodiment of the present invention is not limited thereto.

[0054] The battery cell may be provided with a pole or the like connected to the pole lug as the electrical connection part of the battery cell. In addition, the battery cell may have a pressure relief part. When the internal pressure of the battery cell is too high (for example, thermal runaway), the pressure relief part is used to release the internal substances of the battery cell (for example, gas, liquid, particulate matter, etc.) to reduce the internal pressure of the battery cell and avoid the internal pressure of the battery cell being too quickly pressurized, which may lead to dangerous accidents such as explosion of the battery cell. For example, the pressure relief part may be an explosion-proof valve, an explosion-proof plate, etc.

[0055] The temperature of the discharge from the pressure relief part is very high, for example, it can reach over 300°C, which can cause fire. The battery box is damaged by the high temperature and catches fire. The spread of the fire causes serious economic losses and even affects life safety. In some related technologies, mica sheets are added to separate the pressure relief part from the battery box, which can extend the escape time to a certain extent; however, the effect of extending the fire burning time is limited, and there is still a great risk to the safety of life and property.

[0056] Based on this, an embodiment of the present application proposes a battery 100, which includes a battery box 10, a battery cell 21, and an oxygen-consuming component 30. The battery box 10 has a storage space 101, the battery cell 21 is arranged in the storage space 101, and the battery cell 21 has a pressure relief portion 211. The oxygen-consuming component 30 is arranged in the storage space 101, and the oxygen-consuming component 30 is used to consume oxygen in the storage space 101 when the pressure relief portion 211 is in a pressure relief state.

[0057] In the battery 100 of the above structure, the oxygen-consuming component 30 consumes the oxygen in the accommodating space 101 when the pressure relief portion 211 is in a pressure relief state, thereby quickly reducing the oxygen content in the environment required for fire. This makes it less likely for high-temperature emissions ejected from the pressure relief portion 211 to cause fire, thereby effectively extending the fire burning time.

[0058] The battery 100 disclosed in the embodiment of the present invention can be used in, but not limited to, an electrical device 200 such as a vehicle, a ship or an aircraft. The power system of the electrical device 200 can be composed of the battery 100 disclosed in the present invention to ensure the safety and reliability of the electrical device 200.

[0059] For example, the power-consuming device 200 disclosed in the embodiment of the present invention may be, but is not limited to, a vehicle, a mobile phone, a tablet, a laptop computer, a ship, a spacecraft, an electric toy, an electric tool, etc. The vehicle may be a fuel vehicle, a gas vehicle, a new energy vehicle, or a rail vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle, etc.; the spacecraft includes an airplane, a rocket, a space shuttle, and a spacecraft, etc.; the electric toy includes a fixed or mobile electric toy, such as a game console, an electric vehicle toy, an electric ship toy, and an electric airplane toy, etc.; the electric tool includes a metal cutting electric tool, a grinding electric tool, an assembly electric tool, and a railway electric tool, such as an electric drill, an electric grinder, an electric wrench, an electric screwdriver, an electric hammer, an impact drill, a concrete vibrator, and an electric planer, etc.

[0060] Hereinafter, a battery 100 according to an embodiment of the present invention will be described with reference to the drawings.

[0061] Please refer to Figure 1-Figure 6 and Figure 12-13 , Figure 1 A schematic diagram of the structure of a battery 100 provided in an embodiment of the present invention; Figure 2 A schematic diagram of the structure of the second housing 12 provided in an embodiment of the present invention; Figure 3 A schematic diagram of the matching structure of the first housing 11 and a plurality of battery packs 20 provided in an embodiment of the present invention; Figure 4 A schematic structural diagram of a first housing 11 provided in an embodiment of the present invention; Figure 5-Figure 6 An exploded view of a battery 100 provided in accordance with a first embodiment of the present invention; Figure 12-13 The exploded view of the battery 100 provided in the second embodiment of the present invention. The battery 100 comprises: a battery box 10 and a battery cell 21 .

[0062] Specifically, the battery box 10 has a receiving space 101 , the battery cell 21 is disposed in the receiving space 101 , and the battery cell 21 has a pressure relief portion 211 .

[0063] The battery box 10 may be a single piece or may include a plurality of separate pieces that fit together. Figure 1-Figure 6 and Figure 12-13 As shown, the battery box 10 may include a first shell 11 and a second shell 12 that match each other, the first shell 11 defines a first space, the second shell 12 defines a second space, and the first space and the second space constitute a storage space 101; of course, in other embodiments, the first shell 11 defines a first space to constitute the storage space 101, and the second shell 12 is a plate-shaped end opening for covering the storage space 101; in yet other embodiments, the second shell 12 defines a second space to constitute the storage space 101, and the first shell 11 is a plate-shaped end opening for covering the storage space 101; all of these are within the protection scope of the present invention.

[0064] The battery cell 21 is arranged in the accommodation space 101, so that the battery box 10 can protect the battery cell 21, so as to reduce or prevent the external liquid or other foreign matter from affecting the charging or discharging of the battery cell 21. At the same time, when the battery cell 21 has thermal runaway, the battery box 10 can, to a certain extent, slow down the random eruption and transmission of high-temperature emissions to the outside of the battery 100, thereby reducing damage to other parts of the electrical device 200, such as reducing the high-temperature impact on the vehicle cockpit.

[0065] Continue to refer to Figure 5-Figure 6 and Figure 12-13 The battery 100 may further include an oxygen consuming component 30. The oxygen consuming component 30 is disposed in the accommodation space 101, and the oxygen consuming component 30 is used to consume oxygen in the accommodation space 101 when the pressure relief portion 211 is in a pressure relief state.

[0066] The oxygen-consuming component 30 is a component capable of consuming oxygen. The oxygen-consuming component 30 may be entirely an oxygen-consuming material 34 capable of consuming oxygen, or partly an oxygen-consuming material 34 capable of consuming oxygen.

[0067] For example, the oxygen-consuming component 30 includes an oxygen-consuming material 34, and the oxygen-consuming material 34 includes, but is not limited to, a combination of one or more of red phosphorus, carbon powder, and cobalt crystals. Among them, red phosphorus reacts with oxygen to generate phosphorus pentoxide, carbon powder reacts with the oxygen-consuming material 34 to generate carbon dioxide or carbon monoxide, and cobalt crystals react with oxygen to generate cobalt oxide or cobalt tetraoxide. The heat generated by red phosphorus, carbon powder, and cobalt crystals in the process of reacting with oxygen is lower than the heat of the discharge of the pressure relief part 211, so that the oxygen-consuming process will not cause the fire to worsen, and the reaction with oxygen is violent, which plays a role in quickly consuming oxygen, and suppressing the fire more timely and quickly.

[0068] Furthermore, the oxygen-consuming component 30 is configured to consume oxygen in the accommodation space 101 when the pressure relief portion 211 is in the pressure relief state. When the pressure relief portion 211 is in the pressure relief state, the battery cell 21 emits high-temperature emissions into the accommodation space 101 through the pressure relief portion 211. The high-temperature emissions have the risk of causing fire. At this time, the oxygen-consuming component 30 is used to consume the oxygen in the accommodation space 101, so that the environment in the accommodation space 101 lacks the oxygen necessary for fire, thereby effectively suppressing fire or quickly extinguishing fire after fire, which is conducive to reducing the spread of thermal runaway, reducing the losses caused by thermal runaway, and providing more sufficient time for personnel to escape, greatly improving the safety of use.

[0069] According to the battery 100 of the embodiment of the present invention, an oxygen-consuming component 30 is provided in the accommodating space 101 for accommodating the battery cell 21. The oxygen-consuming component 30 consumes the oxygen in the accommodating space 101 when the pressure relief portion 211 is in a pressure relief state, thereby reducing the oxygen content in the accommodating space 101, thereby effectively suppressing the fire caused by the pressure relief, and providing more time for property rescue and personnel escape in case of thermal runaway.

[0070] According to some embodiments of the present invention, please refer to Figure 7-Figure 11 and Figure 17-Figure 18 , Figure 7-Figure 8 A schematic diagram of the matching structure of the second housing 12 and the oxygen-consuming component 30 provided in the first embodiment of the present invention; Figure 9-10 A schematic diagram of the structure of the oxygen consuming component 30 provided in the first embodiment of the present invention; Fig.11 for Fig.10 A cross-sectional view along the direction indicated by line AA; Figure 17-Figure 18 The oxygen consuming member 30 is a schematic structural diagram of the second embodiment of the present invention. The oxygen consuming member 30 includes an oxygen consuming material 34 and a packaging layer 33 for packaging the oxygen consuming material 34. The temperature resistance of the packaging layer 33 is lower than the temperature of the discharge of the pressure relief portion 211.

[0071] The encapsulation layer 33 is used to encapsulate the oxygen-consuming material 34, that is, the encapsulation layer 33 defines a closed space, and the oxygen-consuming material 34 is filled in the closed space to be isolated from the air in the receiving space 101 and outside the encapsulation layer 33. It should be noted that the encapsulation layer 33 can be made of a hard material so that the shape of the oxygen-consuming part 30 obtained after encapsulation is regular, which is convenient for more stable arrangement and fixation in the receiving space 101; or, the encapsulation layer 33 can be made of a soft material so that the oxygen-consuming part 30 can be deformed to more flexibly adapt to the shape of the receiving space 101.

[0072] The heat resistance temperature of the encapsulation layer 33 refers to the lowest temperature at which the encapsulation layer 33 undergoes thermal deformation. When the actual temperature is lower than the heat resistance temperature of the encapsulation layer 33, the structure of the encapsulation layer 33 remains intact, thereby maintaining the state of encapsulating the oxygen-consuming material 34 to isolate the oxygen-consuming material 34 from the air in the accommodation space 101, and maintaining the oxygen consumption capacity of the oxygen-consuming material 34. For example, in some embodiments, the battery box 10 is provided with a balancing valve, and the balancing valve balances the air pressure of the accommodation space 101 of the battery box 10 with the outside, that is, the outside air can enter the accommodation space 101 through the balancing valve. By providing the encapsulation layer 33, when thermal runaway does not occur, the oxygen-consuming material 34 is not easy to react with oxygen and fail to affect the oxygen consumption during thermal runaway. When the actual temperature is greater than or equal to the heat resistance temperature of the encapsulation layer 33, the structure of the encapsulation layer 33 is destroyed, and the oxygen-consuming material 34 is exposed to the accommodation space 101 and reacts with the oxygen in the accommodation space 101, thereby consuming the oxygen in the accommodation space 101.

[0073] By making the heat-resistant temperature of the packaging layer 33 lower than the temperature of the emission from the pressure relief part 211, the packaging layer 33 remains intact when the battery cell 21 does not experience thermal runaway, and the oxygen-consuming material 34 is not easily invalidated; and the oxygen-consuming material 34 is released in time when the thermal runaway pressure relief part 211 sprays high-temperature emission, so as to consume oxygen in time to suppress fire.

[0074] In some embodiments, the heat resistance of the encapsulation layer 33 is greater than or equal to 100°C and less than or equal to 300°C. Within the above temperature range, the heat resistance of the encapsulation layer 33 is higher than the temperature of the battery 100 under normal working conditions, so that the encapsulation layer 33 is not easily damaged under normal working conditions, causing the oxygen-consuming material 34 to fail; and the heat resistance of the encapsulation layer 33 is not higher than the temperature of the emission when the battery cell 21 is thermally runaway, so that the encapsulation layer 33 can be quickly and timely damaged and release the oxygen-consuming material 34, thereby improving the timeliness and efficiency of oxygen consumption. In some specific embodiments, the heat resistance of the encapsulation layer 33 can be 120°C, 150°C, 200°C, 250°C, 290°C, etc.

[0075] For example, in some specific embodiments, the material of the encapsulation layer 33 may include a plastic material. The plastic material has a strong shape plasticity, so that the oxygen consuming component 30 can be easily formed into any desired shape to match the installation in the accommodation space 101, for example Fig. 9 and Fig.17 As shown, the oxygen consuming member 30 is formed into a long strip with a plurality of grooves. In addition, the plastic material can be quickly broken to release the oxygen consuming material 34 when encountering high-temperature emissions.

[0076] In some embodiments of the present invention, the oxygen-consuming material 34 is in a powdery or granular form with fluidity. After the encapsulation layer 33 is damaged, the oxygen-consuming material 34 inside can quickly flow outward through the damaged opening and disperse, thereby fully contacting with the oxygen in the accommodation space 101, which is conducive to improving the oxygen consumption efficiency.

[0077] In addition, in the embodiment where the oxygen-consuming part 30 is arranged opposite to the pressure relief part 211, the damaged opening formed by the encapsulation layer 33 is opposite to the pressure relief part 211 in the pressure relief state. The oxygen-consuming material 34 flows so that the oxygen-consuming material 34 opposite to the pressure relief part 211 in the pressure relief state can flow to the vicinity of the pressure relief part 211 in time to consume nearby oxygen, thereby improving the fire suppression effect. The oxygen-consuming material 34 opposite to other pressure relief parts 211 can also flow out from the damaged opening, so that the oxygen-consuming material 34 that actually plays a role in oxygen consumption is sufficient, thereby further improving the fire suppression effect.

[0078] According to some embodiments of the present invention, please refer to Figure 3 , Figure 5 and Figure 12-13 , there are multiple battery cells 21. Multiple battery cells 21 constitute a row of battery packs 20, and the battery pack 20 includes multiple battery cells 21 arranged along the second direction F2. Or multiple battery cells 21 constitute multiple rows of battery packs 20, and the multiple rows of battery packs 20 are arranged along the first direction F1, and the battery pack 20 includes multiple battery cells 21 arranged along the second direction F2, so that all battery cells 21 form an array arrangement structure.

[0079] The oxygen consuming parts 30 are arranged in a one-to-one correspondence with the battery packs 20, that is, the number of the battery packs 20 is equal to the number of the oxygen consuming parts 30, and the battery 100 includes one or more oxygen consuming parts 30. The oxygen consuming parts 30 extend along the second direction F2 and are arranged opposite to the pressure relief parts 211 of the multiple battery cells 21 of the same battery pack 20 along the third direction F3, and the first direction F1, the second direction F2 and the third direction F3 intersect each other.

[0080] The oxygen-consuming component 30 extends along the second direction F2 , which should be understood in a broad sense. In the second direction F2 , the oxygen-consuming component 30 may extend along a straight line, or along a curved line, a broken line or other path.

[0081] The oxygen consuming component 30 is arranged opposite to the pressure relief parts 211 of the multiple battery cells 21 of the same battery pack 20 along the third direction F3, that is, the projection of the pressure relief part 211 of the same battery pack 20 along the third direction F3 at least partially overlaps with the oxygen consuming component 30. Therefore, when the pressure relief part 211 sprays emissions outward during thermal runaway, the emissions can be accurately sprayed onto the oxygen consuming component 30, so that the oxygen consuming component 30 can consume oxygen in time, improve the oxygen consumption efficiency, and thus improve the effect of suppressing fire.

[0082] The first direction F1, the second direction F2 and the third direction F3 intersect each other, where the intersection includes being perpendicular to each other or forming a certain angle. Figure 5 The first direction F1 is the left-right direction, the second direction F2 is the front-back direction, and the third direction F3 is the up-down direction. By adopting the above-mentioned arrangement, the arrangement directions of the multiple battery cells 21 and the corresponding directions of the pressure relief parts 211 and the oxygen-consuming parts 30 do not interfere with each other, so that each pressure relief part 211 will not be blocked by other battery cells 21 when spraying out emissions, and can trigger the oxygen-consuming parts 30 to consume oxygen in time.

[0083] In some embodiments of the present invention, the size of the oxygen consuming component 30 along the third direction F3 may be uniform everywhere, or may be partially thickened or partially thinned as needed. Figure 9-10 and Figure 17-Figure 18 The oxygen consumption part 30 includes a second oxygen consumption part 32 and a plurality of first oxygen consumption parts 31, the plurality of first oxygen consumption parts 31 are arranged along the second direction F2, and the second oxygen consumption part 32 connects two adjacent first oxygen consumption parts 31. The first oxygen consumption part 31 is opposite to the pressure relief part 211 along the third direction F3, and the size of the first oxygen consumption part 31 along the third direction F3 is larger than the size of the second oxygen consumption part 32 along the third direction F3.

[0084] The second oxygen consumption part 32 may be one or more. For example, the oxygen consumption part 30 includes two first oxygen consumption parts 31 and one second oxygen consumption part 32 , or the oxygen consumption part 30 includes at least three first oxygen consumption parts 31 and at least two second oxygen consumption parts 32 .

[0085] The first oxygen consumption parts 31 and the second oxygen consumption parts 32 are arranged alternately in the second direction F2.

[0086] The first oxygen consumption part 31 is opposite to the pressure relief part 211 along the third direction F3, that is, the projection of the first oxygen consumption part 31 along the third direction F3 at least partially overlaps with the pressure relief part 211, so that the emission ejected from the pressure relief part 211 can directly impact the first oxygen consumption part 31. The projection of the second oxygen consumption part 32 along the third direction F3 can be at least partially offset from the pressure relief part 211, that is, not overlapped.

[0087] The first oxygen consumption part 31 opposite to the pressure relief part 211 is relatively large in size to meet the amount of oxygen that can be consumed by the first oxygen consumption part 31 when the pressure relief part 211 is in a pressure relief state, and the second oxygen consumption part 32 connected to the first oxygen consumption part 31 can assist in oxygen consumption when the oxygen consuming material 34 has a certain fluidity to improve the oxygen consumption efficiency. In addition, the size of the second oxygen consumption part 32 is relatively small, which can reduce the total amount of oxygen consuming material 34 to a certain extent and reduce the cost of the oxygen consuming part 30.

[0088] It should be noted that in Fig. 9 and Fig.17 In the example shown, the surfaces of the first oxygen consumption part 31 and the second oxygen consumption part 32 on one side along the third direction F3 are coplanar, so that the oxygen consumption part 30 can be stably installed in the accommodation space 101, and the surfaces on the other side are not coplanar to form a groove. However, the structures of the first oxygen consumption part 31 and the second oxygen consumption part 32 are not limited thereto, for example, the surfaces of the first oxygen consumption part 31 and the second oxygen consumption part 32 on both sides along the third direction F3 may not be coplanar.

[0089] In some embodiments where the oxygen consuming member 30 includes a packaging layer 33 and an oxygen consuming material 34 , the packaging layer 33 can encapsulate the oxygen consuming material 34 by blistering, and simultaneously form the first oxygen consuming portion 31 and the second oxygen consuming portion 32 of different sizes.

[0090] According to some embodiments of the present invention, please refer to Figure 5-Figure 6 and Figure 12-16 , Fig.14 An exploded view of the wiring harness isolation plate 40, the electrical connector 5050 and the oxygen consuming component 30 provided in the second embodiment of the present invention; Figure 15-16 The schematic diagram of the matching structure of the wire harness isolator 40, the electrical connector 5050 and the oxygen consuming component 30 provided in the second embodiment of the present invention. The battery 100 may further include a wire harness isolator 40, which is disposed in the accommodation space 101 and located on one side of the battery cell 21 along the third direction F3.

[0091] In order to enable the battery 100 to achieve normal transmission of electric energy, the battery cells 21 in the battery 100 need to be connected in series, in parallel or in mixed connection through the electrical connector 5050 (such as a bus bar or a bar). In order to collect the temperature and voltage of the battery 100, the wiring harness needs to be connected to the bus bar, and the electrical connector 5050 and the wiring harness connected thereto need to be isolated by the wiring harness isolation plate 40.

[0092] For example Figure 5 and Fig.12 As shown, a harness isolation plate 40 is provided between the battery cell 21 and the second housing 12 . Fig.19The figure is a schematic diagram of the structure of the battery cell 21 provided in an embodiment of the present invention. The battery cell 21 is provided with an electrical connection portion 212 on one side along the third direction F3 toward the wiring harness isolation plate 40. The electrical connector 5050 is electrically connected to the electrical connection portion 212 by welding or the like to realize series connection, parallel connection or mixed connection between multiple battery cells 21.

[0093] In some embodiments including the harness isolation plate 40, please refer to Figure 5-Figure 8 The oxygen consuming component 30 may be installed in the battery box 10, for example, in the second housing 12 of the battery box 10. The harness isolation plate 40 is provided with an escape hole 41 penetrating along the third direction F3 and used to escape the oxygen consuming component 30.

[0094] The oxygen consuming component 30 is installed in the battery box 10, so that the space for installing the oxygen consuming component 30 in the accommodating space 101 is larger. For example, in the third direction F3, the entire space between the second housing 12 and the pressure relief portion 211 can be used to accommodate the oxygen consuming component 30. As a result, the oxygen consumption capacity of the oxygen consuming component 30 is more convenient to control, which is conducive to improving the oxygen consumption effect of the oxygen consuming component 30 and the fire suppression effect.

[0095] The avoidance hole 41 avoids the oxygen-consuming component 30 and needs to be understood in a broad sense, that is, the oxygen-consuming component 30 can extend into the avoidance hole 41 or pass through the avoidance hole 41, or the oxygen-consuming component 30 is completely located on the side of the avoidance hole 41 that is away from the battery cell 21. This can reduce or avoid the shielding of the oxygen-consuming component 30 by the harness isolation plate 40, so that the emissions sprayed from the pressure relief part 211 can be directly sprayed onto the oxygen-consuming component 30, so that the oxygen-consuming component 30 can respond in time. In the embodiment where the oxygen-consuming material 34 has fluidity, the avoidance hole 41 allows the oxygen-consuming material 34 of the oxygen-consuming component 30 to flow smoothly to the pressure relief part 211 for oxygen consumption.

[0096] It should be noted that the avoidance hole 41 can be as follows Figure 5 The size of the oxygen consuming part 30 is shown to match, for example Figure 5 As shown, it is formed into a long strip with the same shape as the oxygen-consuming part 30. However, the structure of the avoidance hole 41 includes but is not limited to this. For example, the oxygen-consuming part 30 may correspond to a plurality of avoidance holes 41, and the avoidance holes 41 are arranged one-to-one with the pressure relief part 211. For example, in some embodiments including the first oxygen-consuming part 31 and the second oxygen-consuming part 32, the avoidance holes 41 may be a plurality of avoidance holes 41 arranged along the second direction F2, and the plurality of avoidance holes 41 are arranged one-to-one with the plurality of first oxygen-consuming parts 31, which is also within the protection scope of the present invention.

[0097] In some embodiments, please refer to Fig. 9, the dimension L1 of the oxygen-consuming component 30 along the third direction F3 is greater than or equal to 20 mm and less than or equal to 50 mm, that is, 20 mm ≤ L1 ≤ 50 mm. For example, the dimension of the oxygen-consuming component 30 along the third direction F3 can be 20 mm, 30 mm, 40 mm, and 50 mm, etc. Within the above-mentioned dimension range, the dimension of the oxygen-consuming component 30 along the third direction F3 is larger to meet the oxygen consumption requirement, and the dimension of the oxygen-consuming component 30 along the third direction F3 is not too large to cause position interference with other components or cause material waste.

[0098] The connection method between the oxygen consuming component 30 and the battery box 10 can be flexibly set, for example, one or a combination of methods such as bonding, snap-on connection, and embedded connection can be used.

[0099] For example Figure 7 and Figure 8 As shown, the oxygen-consuming component 30 is bonded to the battery box 10, the connection method is simple, and the fixation is firm and reliable, so that the oxygen-consuming component 30 can be stably maintained at a position relative to the pressure relief portion 211, so that oxygen consumption is timely and effective.

[0100] For another example, a first mounting groove may be provided on the side of the battery box 10 facing the harness isolation plate 40, and the oxygen-consuming component 30 is at least partially embedded in the first mounting groove. For example, the second shell 12 of the battery box 10 may be provided with a first mounting groove, and the oxygen-consuming component 30 is embedded in the first mounting groove along the third direction F3. By providing the first mounting groove, not only can the space available for accommodating the oxygen-consuming component 30 in the third direction F3 be increased, so as to increase the volume and oxygen consumption capacity of the oxygen-consuming component 30, but also it is beneficial to use the groove wall of the first mounting groove in a direction perpendicular to the third direction F3 to limit the oxygen-consuming component 30, so that the oxygen-consuming component 30 is maintained in the set position and opposite to the pressure relief portion 211, so that the oxygen consumption is timely and effective.

[0101] Of course, the oxygen-consuming component 30 and the battery box 10 can be connected by bonding or embedding into the first mounting groove, which is also within the protection scope of the present invention.

[0102] In some embodiments including the harness isolation plate 40, please refer to Figure 12-16 , the oxygen-consuming component 30 can be installed on the harness isolation plate 40. The harness isolation plate 40 is close to the battery cell 21, which is conducive to making the oxygen-consuming component 30 closer to the pressure relief portion 211, so that it can respond more quickly when the pressure relief portion 211 sprays emissions, start consuming oxygen more promptly, reduce the oxygen-consuming material 34 required to be consumed, and improve the effect of suppressing fire.

[0103] In some embodiments, please refer to Fig.17, the dimension L2 of the oxygen-consuming component 30 along the third direction F3 is greater than or equal to 10 mm and less than or equal to 20 mm, that is, 10 mm ≤ L2 ≤ 20 mm. For example, the dimension of the oxygen-consuming component 30 along the third direction F3 can be 10 mm, 12 mm, 15 mm, 18 mm, and 20 mm, etc. Within the above-mentioned dimension range, the dimension of the oxygen-consuming component 30 along the third direction F3 is small, and it is not easy to cause position interference with other components, and the dimension of the oxygen-consuming component 30 along the third direction F3 is not too small to affect the fire suppression effect.

[0104] The connection method between the oxygen consuming component 30 and the wiring harness isolation plate 40 can be flexibly set, for example, one or a combination of several methods such as bonding, clamping, and embedded connection can be adopted.

[0105] For example Figure 14-16 As shown, the wire harness isolation plate 40 is provided with a second mounting groove 42 on one side facing the battery cell 21, and the oxygen-consuming component 30 is at least partially embedded in the second mounting groove 42. By providing the second mounting groove 42, not only can the space between the wire harness isolation plate 40 and the battery cell 21 for accommodating the oxygen-consuming component 30 be increased, so as to increase the volume and oxygen-consuming capacity of the oxygen-consuming component 30, but also the groove wall of the second mounting groove 42 is used to limit the oxygen-consuming component 30 in a direction perpendicular to the third direction F3, so that the oxygen-consuming component 30 is kept at a set position and opposite to the pressure relief portion 211, so that oxygen consumption is timely and effective.

[0106] For another example, the harness isolation plate 40 is bonded to the oxygen consuming component 30. The connection method is simple, the fixation is firm and reliable, so that the oxygen consuming component 30 can be stably maintained at a position relative to the pressure relief portion 211, so that the oxygen consumption is timely and effective.

[0107] Of course, the oxygen consuming component 30 and the wiring harness isolation plate 40 can be connected by bonding or embedding into the second mounting groove 42, which is also within the protection scope of the present invention.

[0108] In some embodiments, Figure 14-16 As shown, the harness isolation plate 40 may also be provided with a mounting hole 43, and the mounting hole 43 penetrates the harness isolation plate 40 along the third direction F3. The electrical connector 5050 may be located in the mounting hole 43, and the electrical connector 5050 is used to connect with the electrical connection portion 212 of the battery cell 21 to achieve series connection, parallel connection or mixed connection of the battery cell 21. By providing the mounting hole 43, the electrical connection can be limited, and the connection operation of the electrical connector 5050 and the electrical connection portion 212 is facilitated.

[0109] The electric device 200 according to the second embodiment of the present invention comprises the battery 100 according to the first embodiment of the present invention, and the battery 100 is used to provide electric energy for the electric device 200. Therefore, by adopting the above-mentioned battery 100, the oxygen consuming part 30 is used to consume the oxygen in the accommodation space 101 when the pressure relief part 211 is in the pressure relief state, so that the oxygen content in the accommodation space 101 is reduced, so as to effectively suppress the fire caused by the pressure relief, and provide more time for property rescue and personnel escape in case of thermal runaway.

[0110] Alternatively, if Fig. 20 As shown, when the battery 100 is used in a vehicle, the battery 100 can be arranged at the bottom, head, or tail of the vehicle. The battery 100 can be used to power the vehicle, for example, the battery 100 can be used as an operating power source for the vehicle. The vehicle can also include a controller and a motor, and the controller is used to control the battery 100 to power the motor, for example, for starting, navigating, and driving the vehicle.

[0111] The following describes a battery 100 and a vehicle having the same according to two specific embodiments of the present invention with reference to the accompanying drawings.

The battery box 10 includes a first shell 11 and a second shell 12. The second shell 12 is covered on the top of the first shell 11 to cooperate to define a storage space 101. A plurality of battery packs 20 are arranged in the storage space 101 of the battery box 10 along a first direction F1. Each battery pack 20 includes a plurality of battery cells 21 arranged along a second direction F2. An electrical connection portion 212 and a pressure relief portion 211 are provided on the upper side of the battery cell 21. The harness isolation plate 40 is located in the storage space 101 and between the battery cell 21 and the second shell 12. A plurality of oxygen-consuming parts 30 are arranged one by one with a plurality of battery packs 20. Each oxygen-consuming part 30 includes a plurality of first oxygen-consuming parts 31 and a plurality of second oxygen-consuming parts 32 arranged alternately along the second direction F2. The oxygen-consuming component 30 includes a packaging layer 33 and an oxygen-consuming material 34 packaged by the packaging layer 33 . The packaging layer 33 is made of plastic, and the oxygen-consuming material 34 is a cobalt crystal that can quickly consume oxygen.

[0114] Please refer to Figure 5-Figure 8In the first embodiment of the present invention, the oxygen consuming component 30 is integrated at the lower side of the second housing 12 and has a thickness of 20 to 50 mm along the third direction F3. The harness isolation plate 40 is provided with a plurality of avoidance holes 41 corresponding to the plurality of oxygen consuming components 30 one by one, so that the plurality of first oxygen consuming parts 31 of the oxygen consuming component 30 can be arranged opposite to the pressure relief parts 211 of the plurality of battery cells 21 of the same battery pack 20.

[0115] Please refer to Figure 12-16 In the second embodiment of the present invention, the oxygen consuming member 30 is integrated on the lower side of the harness isolation plate 40 and has a thickness of 10 to 20 mm along the third direction F3.

[0116] The oxygen-consuming component 30 is arranged directly above the pressure relief portion 211. When the battery cell 21 has thermal runaway, the pressure relief portion 211 sprays emissions outward. The emissions or the formed flames can immediately ignite the packaging layer 33 of the oxygen-consuming component 30, and quickly release the oxygen-consuming material 34 that consumes oxygen, thereby achieving the purpose of suppressing the fire of the battery 100 and prolonging the escape time for personnel.

[0117] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.
