These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0051] It should be noted that, unless otherwise stated, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by those skilled in the art to which the embodiments of this application pertain.

[0052] In the description of the embodiments of this application, the technical terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0053] Furthermore, technical terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise explicitly defined.

[0054] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0055] In the description of the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0056] Currently, judging from market trends, battery applications are becoming increasingly widespread. Batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of battery applications, market demand is also constantly increasing.

[0057] When existing batteries experience thermal runaway, they often release a mixture of high-temperature substances. When this mixture comes into full contact with air, it can easily cause the battery to ignite or even explode, posing a safety risk to users.

[0058] Based on the above phenomenon, the inventor designed a cooling device to cool the battery. However, the inventor further discovered that even if the battery is cooled, it will still release high-temperature mixed substances when thermal runaway occurs, thus posing a safety risk.

[0059] Therefore, the inventors believed that the flammable fumes generated by the thermal runaway of a single battery cell could be treated to be non-flammable. To treat the fumes and reduce their flammability, the inventors discovered that a treatment structure could be set up to treat the fumes generated by thermal runaway, thereby reducing the parameters related to flammability in the fumes and lowering the likelihood of combustion. This would make the battery less prone to combustion even during thermal runaway, thus improving its safety.

[0060] Based on the above considerations, in order to improve the processing performance of the current collector, the inventors conducted in-depth research and designed a battery. By setting up a discharge treatment device, the processing space of the discharge treatment device is connected to the pressure relief mechanism of the battery cell. When the material discharged by the pressure relief mechanism enters the processing space, the processing component processes the discharged material to reduce the specified parameters, which greatly reduces the possibility of the material burning. This makes the battery less likely to burn even in the event of thermal runaway, which is beneficial to improving the safety of the battery.

[0061] The battery cells disclosed in this application can be, but are not limited to, rechargeable battery cells. A rechargeable battery cell refers to a battery that can be recharged after discharge to activate the active materials and continue to be used. The battery cell is equipped with a pressure relief mechanism, which can release the internal materials of the battery cell in the event of thermal runaway, thus achieving pressure relief.

[0062] This application provides a battery cell that can be used, but is not limited to, in electrical devices such as vehicles, ships, or aircraft. A power system for such an electrical device can be constructed using the battery cell and battery disclosed in this application. This helps reduce the possibility of combustion in the exhaust fumes from the battery elevator, and also makes the battery cell and battery less prone to combustion in the event of thermal runaway, thus improving the safety of the battery cell and battery.

[0063] This application provides an electrical device that uses a battery as a power source. The electrical device can be, but is not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, etc. Electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0064] For ease of explanation, the following embodiments will be described using a vehicle 1000 as an example of an electrical device according to an embodiment of this application.

[0065] Please refer to Figure 1 , Figure 1This is a schematic diagram of the structure of a vehicle 1000 provided in some embodiments of this application. The vehicle 1000 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. A battery 100 is disposed inside the vehicle 1000, and the battery 100 can be located at the bottom, front, or rear of the vehicle 1000. The battery 100 can be used to power the vehicle 1000; for example, the battery 100 can serve as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the battery 100 to supply power to the motor 300, for example, to meet the power needs of the vehicle 1000 during startup, navigation, and driving.

[0066] In some embodiments of this application, the battery 100 can not only serve as the operating power source for the vehicle 1000, but also as the driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0067] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a battery 100 provided in some embodiments of this application. The battery 100 includes multiple battery cells 20, which can be connected in series, parallel, or a combination thereof. A combination thereof means that some of the multiple battery cells 20 are connected in series and others in parallel. Alternatively, the battery 100 can be composed of multiple battery cells 20 first connected in series, parallel, or a combination thereof to form a battery module, and then these battery modules are further connected in series, parallel, or a combination thereof to form a whole, housed within a housing 10. The battery 100 may also include other structures; for example, it may include a busbar component for electrical connection between the multiple battery cells 20.

[0068] Each battery cell 20 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited to these. The battery cell 20 can be cylindrical, flat, cuboid, or other shapes.

[0069] Please refer to Figure 3 , Figure 3 This is an exploded structural diagram of a battery cell 20 provided in some embodiments of this application. The battery cell 20 refers to the smallest unit that makes up a battery. Figure 3 The battery cell 20 includes an end cap 21, a housing 22, a cell assembly 23, a pressure relief mechanism (not shown in the figure), and other functional components.

[0070] According to some embodiments of this application, Figure 4This is a schematic diagram showing the disassembled battery provided in some embodiments of this application. This application provides a battery including a battery cell 1 and a discharge processing device. The battery cell 1 has a pressure relief mechanism configured to discharge substances inside the battery cell 1. The discharge processing device includes a processing space 2 configured to communicate with the outer surface of the pressure relief mechanism, allowing substances discharged by the pressure relief mechanism to enter the processing space 2. The discharge processing device also includes a processing element 3 disposed in the processing space 2, which processes the substances to reduce specified parameters in the substances.

[0071] The pressure relief mechanism can refer to a structure installed on the battery cell 1, which can open when the battery cell 1 experiences thermal runaway and the internal pressure exceeds a preset value, releasing the material inside the battery cell 1, reducing the internal pressure of the battery cell 1, and improving the safety of the battery cell 1.

[0072] The processing space 2 refers to the space formed by the venting and processing device. The processing space 2 is connected to the outer surface of the pressure relief mechanism, allowing the substances vented by the pressure relief mechanism to be discharged into the processing space 2. The processing space 2 serves as a temporary containment space for the substances. In the battery 100, the processing space 2 can be a space independent of the space where the battery cell 1 is placed, or the processing space 2 and the space where the battery cell 1 is placed can be set as the same. This allows for rapid and timely processing of the vented substances, which is beneficial to improving battery safety.

[0073] The processing unit 3 can refer to a device that has the function of processing materials. It is set in the processing space 2 and can process the materials in the processing space 2, thereby reducing the specified parameters of the materials in the processing space 2.

[0074] Through the above scheme, the substance released by the battery cell 1 is treated by the treatment unit 3, and the specified parameters in the substance are reduced. After the specified parameters of the substance are reduced, the possibility of the substance burning is greatly reduced, and the battery is less likely to catch fire when thermal runaway occurs, which helps to improve the safety of the battery.

[0075] In some embodiments of this application, the specified parameter is at least one of temperature, combustible particle concentration, or combustible gas concentration.

[0076] Temperature refers to the temperature of a substance. Lowering the temperature of a substance below its ignition point makes it less likely to ignite and burn. Combustible particle concentration refers to the amount of combustible particles contained in a unit volume of a substance. Lowering the combustible particle concentration further reduces the likelihood of combustion. Combustible gas concentration refers to the amount of combustible gas contained in a unit volume of a substance. Lowering the combustible gas concentration further reduces the likelihood of combustion. By reducing these specified parameters, the possibility of combustion is effectively reduced, making the battery less prone to ignition and improving its safety.

[0077] In some embodiments of this application, the processing component 3 includes a spray assembly 31 and a liquid supply assembly 32. The spray assembly 31 is disposed in the processing space 2 and is used to spray the processing liquid into the processing space 2. The liquid supply assembly 32 is connected to the spray assembly 31 and is used to supply the processing liquid to the spray assembly 31.

[0078] The spray assembly 31 can refer to a combination component that can spray out the treatment liquid and make the treatment liquid form fine water droplets scattered in all directions. It is installed in the treatment space 2 and can spray the treatment liquid into the treatment space 2, which increases the contact area between the treatment liquid and the substances in the treatment space 2, and is beneficial to improving the treatment effect and efficiency of the treatment component 3 on the substances.

[0079] When the treatment fluid comes into contact with a substance, it not only exchanges heat with the substance, lowering its temperature, but also captures combustible particles within the substance, reducing their concentration. The treatment fluid can be ultrapure water, fluorinated liquid, or other liquids. These liquids are highly inert, unlikely to react chemically with the substance, thus improving safety during use. Upon heating, they also rapidly vaporize, carrying away heat from the substance. Furthermore, the vaporized treatment fluid further reduces the concentration of combustible particles or gases within the substance.

[0080] The liquid supply component 32 can refer to the component that can supply the treatment liquid with a certain pressure to the spray component 31, so that the treatment liquid can be sprayed into the treatment space 2 under the action of the spray component 31 at a certain pressure. This is beneficial to expand the spray area of ​​the spray component 31 and improve the uniformity of spraying, and makes it easier for the substances released by the pressure relief mechanism to come into contact with the treatment liquid.

[0081] In some embodiments of this application, the battery includes a battery box 4, and the battery cell 1 is placed in the battery box 4. The discharge treatment device also includes a treatment box 5 that forms a treatment space 2 inside. The treatment box 5 has an opening that communicates with the treatment space 2. The treatment box 5 is disposed on the end face of the battery box 4 through the opening.

[0082] The battery box 4 can be a box-shaped structure with an internal accommodating space where the battery cell 1 is placed, and the battery box 4 protects the battery cell 1. Optionally, the battery cell 1 contacts the battery box 4, allowing heat exchange between the battery cell 1 and the battery box 4. The processing box 5 can refer to a box-shaped structure that encloses the processing space 2 to accommodate and process the substances released by the pressure relief mechanism. The opening can refer to a structure formed in the processing box 5 that communicates with the processing space 2, giving the processing box 5 an open structure, allowing the processing box 5 to be exposed to the outer end face of the battery box 4 through the opening.

[0083] In some embodiments of this application, the opening of the processing box 5 may also be provided with a cover plate 50, which is fixedly connected to the outer end face of the battery box 4 by welding, and the cover plate 50 and the battery box 4 have good heat transfer.

[0084] With the above structure, the discharge treatment device can be located outside the battery box 4. The discharge treatment device does not occupy the space inside the battery box 4, which helps to alleviate the tightness of the internal space of the battery box 4, increases the proportion of the battery cell 1 occupying the internal space of the battery box 4, and helps to improve the energy density of the battery.

[0085] Furthermore, by setting the discharge treatment device outside the battery box 4 through the above structure, it is convenient to assemble the battery box 4 and the discharge treatment device separately during production. After the two are assembled separately, they are then assembled together, which can effectively improve the manufacturing efficiency of this product and is conducive to the mass production of the product.

[0086] In some embodiments of this application, the spray assembly 31 is configured to face the end face to spray the treatment liquid toward the end face.

[0087] The spray assembly 31 is oriented towards the end face, so that the treatment liquid sprayed by the spray assembly 31 can reach the end face of the battery box 4. The treatment liquid can exchange heat with the battery box 4 and carry away the heat generated by the battery cell 1 during thermal runaway, thus cooling the battery cell 1, which helps to reduce the possibility of danger and improve the safety of the battery.

[0088] Through the above method, the treatment fluid can not only treat the materials, but also cool the battery, which helps to improve the battery's safety.

[0089] In some embodiments of this application, the battery includes a housing with a partition that divides the housing into two spaces, one of which is a processing space 2, and the other of which is used to place a single battery cell 1.

[0090] The housing can refer to a structure with an internal cavity that protects the components within it. The separator can refer to a structural component within the housing that divides the cavity into two spaces: a processing space 2 and a space for placing the battery cell 1. Optionally, the battery cell 1 contacts the separator, allowing heat exchange between the battery cell 1 and the separator.

[0091] In some embodiments of this application, the spray assembly 31 is configured to face the separator for heat exchange between the treatment liquid and the separator.

[0092] The spray assembly 31 is positioned towards the separator, so that the treatment liquid sprayed by the spray assembly 31 can reach the separator. The treatment liquid can exchange heat with the separator and carry away the heat generated by the battery cell 1 during thermal runaway, thus cooling the battery cell 1, which helps to reduce the possibility of danger and improve battery safety.

[0093] Through the above scheme, the treatment liquid can not only treat the material, but also cool the battery cell 1, which is beneficial to improving the safety of the battery.

[0094] In some embodiments of this application, such as Figure 5 As shown, the spray assembly 31 includes a liquid supply line 311 and a nozzle 312. The nozzle 312 is connected to the liquid supply line 311, and the liquid supply line 311 is connected to the liquid supply assembly 32.

[0095] Nozzle 312 can refer to a device disposed in the processing space 2, which can process the processing liquid into fine droplets and spray them into the processing space 2 to achieve atomization of the processing liquid, so that the processing liquid has a larger contact area with the material, which is beneficial to improving the processing effect of the material.

[0096] The liquid supply line 311 can refer to a section of pipe that can be arranged in the processing space 2, which is connected to the nozzle 312 and can deliver the processing liquid with a certain pressure to the nozzle 312. Optionally, the nozzle 312 is connected to the liquid supply line 311, thereby achieving relative fixation between the nozzle 312 and the liquid supply line 311.

[0097] In some embodiments of this application, the liquid supply pipeline 311 is provided with a connecting part 3112, and the inner wall of the processing space 2 is provided with a connecting groove, and the connecting part 3112 is connected to the connecting groove.

[0098] The connecting part 3112 can refer to a protruding structure provided on the liquid supply pipeline 311. It can be formed by connecting a block structure on the liquid supply pipeline 311 through welding or bolt connection or other connection methods, or it can be integrally formed with the liquid supply pipeline 311 during the manufacturing process. Those skilled in the art can select the forming method of the connecting part 3112 according to the actual situation.

[0099] The inner wall of the processing space 2 can refer to the side of the wall surrounding the processing space 2 that is close to the processing space 2. When the processing space 2 is formed by a partition box, the inner wall of the processing space 2 can be the side of the partition box that is close to the processing space 2, or it can be the side of the box that is close to the processing space 2. When the processing space 2 is formed by a processing box 5, the inner wall of the processing space 2 can be the end face of the battery box 4 provided on the opening of the processing box 5, or it can be the inner side of the processing box 5 that is close to the processing space 2.

[0100] The connection groove may refer to a groove-shaped structure provided on the inner wall of the processing space 2, which is arranged in a matching manner with the connecting portion 3112, and the connecting portion 3112 can be inserted into the connection groove. By providing a connection groove on the inner wall of the processing space 2 that cooperates with the connecting portion 3112, the fixing of the processing member 3 in the processing space 2 is achieved, which can prevent the liquid supply pipeline and the nozzle from moving in the processing space and reduce the possibility of collision.

[0101] In some embodiments of the present application, the liquid supply pipeline 311 is arranged in a loop shape, and a plurality of nozzles 312 are provided. The plurality of nozzles 312 are arranged at equal intervals along the liquid supply pipeline 311.

[0102] The loop shape may refer to a shape formed by the liquid supply pipeline 311 being bent multiple times. The liquid supply pipeline 311 is arranged in a loop shape in the processing space 2, which is beneficial to the uniform distribution of the liquid supply pipeline 311 in the processing space 2.

[0103] The plurality of nozzles 312 are arranged at equal intervals along the liquid supply pipeline 311, so that the plurality of nozzles 312 on the liquid supply pipeline 311 can be evenly arranged in the processing space 2, and the processing liquid sprayed by the nozzles 312 can be evenly distributed in the processing space 2, which is beneficial to improving the processing effect and processing efficiency of the processing liquid on the substance.

[0104] In some embodiments of the present application, the liquid supply component 32 includes a liquid tank 321 and an infusion power component 322. The infusion power component 322 is connected between the liquid tank 321 and the inlet of the liquid supply pipeline 311.

[0105] In some embodiments of the present application, the liquid supply component 32 is arranged on the battery. The liquid supply component 32 is connected to the battery box 4 through connecting members such as connecting bolts, so that the liquid supply component 32 can be installed together with the battery box 4, making the installation convenient. In some embodiments of the present application, the liquid supply component 32 can also be arranged on an electrical device such as a vehicle. The liquid supply component 32 is connected to the liquid supply pipeline 311 through an infusion pipeline. Arranging the liquid supply component 32 on the vehicle electrical device can reduce the weight and structural redundancy of the battery. Those skilled in the art can select the installation position of the liquid supply component 32 according to the actual situation.

[0106] The liquid tank 321 may refer to a box structure with a storage space inside, and the storage space contains the processing liquid. The infusion power component 322 can be an infusion pump, which can extract the processing liquid from the liquid tank 321 and can transport the processing liquid in the liquid tank 321 to the liquid supply pipeline 311 under a certain pressure, so that the processing liquid can be evenly sprayed in the processing space 2 under its own pressure.

[0107] In some embodiments of the present application, the discharge treatment device further includes a connection channel 6, and the connection channel 6 is configured to be able to connect the processing space 2 and the outer surface of the pressure relief mechanism.

[0108] The connecting channel 6 can refer to a channel structure used to connect the processing space 2 and the outer surface of the pressure relief mechanism. It can be a channel structure formed in the component structure of the battery. For example, when the processing space 2 is formed by a partition separating the housing, the connecting channel 6 can be a channel opened on the partition. When the processing space 2 is formed by a processing box 5, the connecting channel 6 can be a channel opened on the end face of the box. Alternatively, it can be an additional connecting pipe used as a channel structure to connect the processing space 2 and the outer surface of the pressure relief mechanism.

[0109] In some embodiments of this application, the connection channel 6 is provided with a liquid-blocking structure, which is used to prevent the processing liquid from contacting the battery cell 1.

[0110] The liquid-blocking structure refers to a structure that allows substances discharged from the battery cell 1 during thermal runaway to flow into the processing space 2, without allowing the processing liquid in the processing space 2 to flow towards the pressure relief mechanism. This prevents the processing liquid from contacting the battery cell 1 and reduces the probability of the battery cell 1 short-circuiting.

[0111] In some embodiments of this application, such as Figure 6 As shown, the liquid-blocking structure includes a one-way valve 61. The inlet of the one-way valve 61 is connected to the outer surface of the pressure relief mechanism, and the outlet of the one-way valve 61 is connected to the processing space 2.

[0112] The one-way valve 61 connects the inlet to the outer surface of the pressure relief mechanism and the outlet to the processing space 2, so that the material can only flow from the pressure relief mechanism to the processing space 2. This prevents the processing liquid from flowing to the pressure relief mechanism, avoids the processing liquid from contacting the battery cell 1, and reduces the probability of the battery cell 1 short-circuiting.

[0113] In some embodiments of this application, such as Figure 7 As shown, the liquid-blocking structure includes a bend 62, which is used to block the flow of the treatment liquid along the connecting channel 6 to the pressure relief mechanism.

[0114] The bend 62 can be an S-shaped section provided in the connecting channel 6. This section can block the treatment fluid. When the treatment fluid flows along the connecting channel 6 to the bend 62, it is blocked and will not flow to the pressure relief mechanism.

[0115] In some embodiments of this application, the battery cell 1 includes a first end face and a second end face. The first end face is provided with a pressure relief mechanism, and the second end face is provided with electrode terminals. The first end face is disposed opposite to the connection channel 6.

[0116] The first end face and the second end face can refer to the two end faces of the battery cell 1 that are arranged opposite each other. The pressure relief mechanism and the electrode terminals are respectively arranged at both ends of the battery cell 1, so that the electrode terminals can be far away from the pressure relief mechanism, which helps to reduce the possibility of the treatment liquid coming into contact with the electrode terminals and improves the safety of the battery.

[0117] In some embodiments of this application, the projection of the connecting channel 6 along the through direction of the connecting channel 6 at least partially overlaps with the projection of the pressure relief mechanism, so that the vent of the pressure relief mechanism can be at least partially aligned with the interface of the connecting channel 6, so that the material released from the vent of the pressure relief mechanism can flow into the connecting channel 6 through a shorter path and then enter the processing space.

[0118] In some embodiments of this application, the venting device further includes a switch configured to connect the venting space 2 and the outer surface of the pressure relief mechanism when opened.

[0119] A switch can refer to a structure used to connect or disconnect the connection between the processing space 2 and the outer surface of the pressure relief mechanism. The switch makes the connection between the processing space 2 and the pressure relief mechanism controllable, allowing the operator to connect or disconnect the connection between the processing space 2 and the outer surface of the pressure relief mechanism according to the actual needs.

[0120] The switch can be opened when the pressure relief mechanism is activated, connecting the treatment space 2 and the pressure relief mechanism; it remains closed when the pressure relief mechanism is not activated, disconnecting the treatment space 2 from the pressure relief mechanism. The switch can be opened after the pressure relief mechanism has released the pressure, under the action of the released substance, or it can be opened automatically by the pressure relief mechanism.

[0121] In some embodiments of this application, the switch includes a weak portion configured to, when damaged, allow communication between the processing space 2 and the outer surface of the pressure relief mechanism.

[0122] The weak part can refer to the structure that is easily broken by force. It is blocked between the processing space 2 and the outer surface of the pressure relief mechanism. When the pressure relief mechanism releases the pressure, the weak part breaks under the action of the released substance, and the processing space 2 and the outer surface of the pressure relief mechanism are connected.

[0123] In some embodiments of the above-mentioned technical solutions that have a switch, the battery cell 1 includes a first end face and a second end face. The first end face is provided with a pressure relief mechanism, and the second end face is provided with electrode terminals. The first end face is disposed opposite to the weak part.

[0124] The first end face and the second end face can refer to the two end faces of the battery cell 1 that are arranged opposite each other. The pressure relief mechanism and the electrode terminals are respectively arranged at both ends of the battery cell 1, so that the electrode terminals can be far away from the pressure relief mechanism, which helps to reduce the possibility of the treatment liquid coming into contact with the electrode terminals and improves the safety of the battery.

[0125] In some embodiments of this application, the projection of the weak portion along the thickness direction of the weak portion at least partially coincides with the projection of the pressure relief mechanism. This allows the vent of the pressure relief mechanism to be at least partially aligned with the switch formed by the weak portion, so that the substance released from the vent of the pressure relief mechanism can act on the switch formed by the weak portion.

[0126] In some embodiments of this application, the discharge treatment device further includes a discharge channel 7, which can connect the treatment space 2 and the external space of the battery.

[0127] The discharge channel 7 can refer to a channel structure used to connect the processing space 2 and the external space of the battery. It can be a channel structure formed in the component structure of the battery. For example, when the processing space 2 is formed by a partition box, the connecting channel 6 can be a channel opened on the partition. When the processing space 2 is formed by a processing box 5, the connecting channel 6 can be a channel opened on the end face of the battery box 4. Alternatively, it can be an additional connecting pipe used as a channel structure to connect the processing space 2 and the external space of the battery.

[0128] By setting up the discharge channel 7, the material treated in the treatment space 2 is discharged to the external space of the battery through the discharge channel 7, which reduces the accumulation of the released material in the battery. After the material is treated in the treatment space 2, the specified parameters of the material are reduced. After the specified parameters of the material are reduced, the possibility of the material burning is greatly reduced. The material is also not easy to burn after being discharged from the battery, which helps to improve the safety of the battery.

[0129] In some embodiments of this application, the discharge treatment device further includes a discharge switch 71, which is disposed in the discharge channel 7 and configured to connect the treatment space 2 and the external space of the battery through the discharge channel 7 when opened.

[0130] The discharge switch 71 refers to a switch structure installed in the discharge channel 7, which can be opened when the pressure relief mechanism is activated to release pressure, thus connecting the discharge channel 7; and remain closed when the pressure relief mechanism is not activated, thus cutting off the discharge channel 7. The discharge switch 71 can be opened after the pressure relief mechanism has released pressure, under the action of the released substance, or it can be opened automatically by the pressure relief mechanism, or it can be kept open by an operator.

[0131] In some embodiments of this application, the switch includes a safety valve that is closed when the pressure relief mechanism is not open, and opens when the pressure relief mechanism is open, allowing the material in the processing space 2 to be discharged to the external space of the battery through the discharge channel 7.

[0132] In some embodiments of this application, the battery further includes a recycling module connected to the processing space 2 for recycling the processing liquid.

[0133] The recycling module can refer to a module used to recycle the processing liquid in the processing space 2. It can collect the processing liquid in the processing space 2 for subsequent processing or reuse, thereby reducing the waste of processing liquid.

[0134] In some embodiments, the recycling module is disposed on the battery and connected to the battery box 4 via connecting bolts or other connectors, allowing the recycling module to be installed together with the battery box 4 for convenient installation. In some embodiments of this application, the recycling module can also be disposed on an electrical device such as a vehicle, and the recycling module is connected to the processing space 2 via a pipe. Disposing the recycling module on an electrical device such as a vehicle can reduce the weight of the battery and structural redundancy. Those skilled in the art can select the placement location of the recycling module according to actual conditions.

[0135] In some embodiments of this application, such as Figure 8 As shown, the discharge treatment device includes a recovery unit 51 disposed in the treatment space 2, such as... Figure 9 As shown, the recycling section 51 is configured to protrude toward the bottom of the discharge treatment device to form a recycling tank 52. The recycling section 51 has a recycling hole 511 in the protruding direction, and the recycling hole 511 connects the recycling module and the recycling tank 52.

[0136] The recycling unit 51 can refer to a structure provided in the processing space 2. When the processing space 2 is formed by a partition box, the recycling unit 51 can be a structure formed by the box. When the processing space 2 is formed by a processing box 5, the recycling unit 51 can be a structure formed by the processing box 5.

[0137] The recovery section 51 protrudes towards the bottom of the discharge treatment device to form a recovery tank 52, so that the treatment liquid in the treatment space 2 is collected in the recovery tank 52 under its own gravity, which is beneficial for the centralized recovery or treatment of the treatment liquid.

[0138] The recovery hole 511 can refer to a hole-like structure formed on the recovery section 51, which connects the recovery module and the recovery tank 52, allowing the processing liquid collected in the recovery tank 52 to flow into the recovery module. In some embodiments, the recovery hole 511 is connected to the lowest end of the recovery tank 52 in the height direction, so that as much of the collected processing liquid as possible can flow away from the recovery hole 511.

[0139] In some embodiments of this application, such as Figure 10 As shown, the recycling module includes a recycling power unit 8 and a recycling box 9. The input end of the recycling power unit 8 is connected to the recycling hole 511, and the output end of the recycling power unit 8 is connected to the recycling box 9.

[0140] The recovery power component 8 can be a return pump, which can extract the treatment liquid from the recovery tank 52 and transport the treatment liquid to the recovery box 9, so that the treatment liquid can flow quickly to the recovery box 9 under the action of the recovery pump.

[0141] The recovery tank 9 can refer to a box structure with an internal storage space capable of holding the treatment fluid. The recovery power unit 8 can transport the treatment fluid to the recovery tank 9. In some embodiments of this application, the recovery tank 9 and the liquid tank 321 can be in the same box, making the flow of the treatment fluid a loop, allowing it to be reused in the liquid tank 321 by the discharge treatment device, which helps reduce the waste of the treatment fluid. In some embodiments of this application, the recovery tank 9 can also be connected to the liquid tank 321, so that the treatment fluid recovered by the recovery tank 9 flows into the liquid tank 321 for reuse by the discharge treatment device.

[0142] In some embodiments of this application, the recycling module further includes a filter 10, which is connected between the recycling port 511 and the input end of the recycling power unit 8.

[0143] The filter element 10 can refer to a device with filtration capabilities, which can filter the treatment liquid, separate out impurities such as combustible particles in the treatment liquid, improve the cleanliness of the treatment liquid, help maintain the quality of the treatment liquid, thereby maintaining the treatment liquid's ability to handle released substances, and facilitate the recycling of the treatment liquid.

[0144] According to some embodiments of this application, see Figures 4 to 6 This application provides a battery. In some embodiments of this application, the battery includes a battery cell 1 and a discharge treatment device. The discharge treatment device includes a treatment space 2 with a treatment component 3. The treatment space 2, formed by a treatment box 5 covering the end face of the battery box 4, is connected to the outer surface of the pressure relief mechanism. When the battery cell experiences thermal runaway, the substance discharged by the pressure relief mechanism enters the treatment space 2 through a connecting channel 6. The spraying component 31 in the treatment component 3 sprays a treatment liquid into the treatment space 2 through nozzles 312. The treatment liquid can treat the substance discharged into the treatment space by the pressure relief mechanism, reducing the temperature of the substance, the concentration of combustible particles in the substance, and the concentration of combustible gases. The treated substance is discharged to the external space of the battery through a discharge channel 7. Since the substance discharged by the pressure relief mechanism has been treated by the treatment liquid, the temperature, concentration of combustible particles, and concentration of combustible gases of the substance have all decreased. When the substance is discharged to the external space of the battery, the possibility of combustion is greatly reduced, making the battery less prone to combustion even when thermal runaway occurs, which is beneficial to improving the safety of the battery. This application provides an electrical device that includes the battery provided by the above-described technical solution, the battery being used to provide electrical energy. Because this electrical device includes the battery provided by the above-described technical solution, it has high safety.
