[0063] The battery cell disclosed by embodiments of the present application can be inserted into the power-consuming device such as a vehicle, ship, aircraft, or the like. A power supply system for the power-consuming device can be constructed using the battery cell, battery, or the like disclosed by the present application.

[0064] The embodiments of the present application provide a power-consuming device that uses a battery as a power supply. The power-consuming device may be, for example, a mobile phone, tablet, laptop, electric toy, power tool, electric motorcycle, electric vehicle, ship, spacecraft, or the like, but are not limited to such devices. Electric toys include, for example, stationary or mobile electric toys such as game consoles, electric car toys, electric ship toys, and electric airplane toys, and so on. Spacecraft include, for example, airplanes, rockets, spacecraft, and other space vehicles.

[0065] The battery device comprises a housing and a battery cell. The housing consists of a first part and a second part, the first part being the top cover. The top cover of the battery device is generally a flat structure. In the battery device's operating environment, for example, when used in a vehicle, the battery device is often set in motion by the vehicle's movement, causing the top cover to vibrate. This vibration can produce noise in some areas with a larger amplitude, leading to noise pollution and negatively impacting the user experience.

[0066] Based on the above considerations and to solve the technical problem that the top cover of the battery device causes noise when vibrated in current technology, the present application proposes a battery device and a power-consuming device. The battery device comprises a box and a damping layer. The box comprises a first part and a second part, which are connected to each other. The second part forms a receiving chamber with an opening, and the first part is positioned adjacent to the opening. The first part comprises the top cover. The damping layer is connected to the first part and arranged on the surface of at least one side of the top cover. When the top cover vibrates, the damping layer vibrates along with it, thereby preventing or reducing the noise generated by the top cover through damping.Therefore, the top cover with a damping layer is less likely to generate noise, thus reducing noise pollution to the environment, protecting the environment and improving the user experience.

[0067] For the sake of simplicity, the following embodiments are described using a vehicle as an example of a power-consuming device according to an embodiment of the present application.

[0068] With reference to Fig. 1 is Fig. 1 a schematic structural representation of a vehicle according to one or more embodiments of the present application.

[0069] The vehicle 1000 can be a fuel-powered vehicle, a gas-powered vehicle, or a vehicle with a new energy source, and the new energy source vehicle can be a pure electric vehicle, a hybrid vehicle, a range-extended vehicle, or the like. A battery device 100 is arranged in the vehicle 1000; the battery device 1000 can be located at the bottom, at the front, or at the rear of the vehicle 1000. The battery device 1000 can be used to supply power to the vehicle 1000. For example, the battery device 1000 can serve as the operating power source for the vehicle 1000. The vehicle 1000 can further include a controller 200 and a motor 300. The controller 200 is used to control the battery device 1000 and to supply power to the motor 300, for example, to meet the operating power requirements of the vehicle 1000 during starting, navigation, and driving.

[0070] In some embodiments of the present application, the battery device 100 can serve not only as an operating current source for the vehicle 1000, but also as a propulsion current source for the vehicle 1000, replacing fuel or natural gas wholly or partially to provide propulsion power for the vehicle 1000.

[0071] With reference to Fig. 2 and Fig. 3 is Fig. 2 A schematic structural representation of the battery device according to one or more embodiments of the present application. The battery device 100 comprises a box 10 and a battery cell 20, the battery cell 20 being received in the box 10. The box 10 serves to provide a receiving space for the battery cell 20, and the box 10 can assume various structures. In some embodiments, the box 10 is provided to comprise a first part 11 and a second part 12, the first part 11 and the second part 12 overlapping each other. The first part 11 and the second part 12 together define a receiving space for receiving a battery cell 20.The second part 12 can be a hollow structure with an open end; the first part 11 can be a plate-shaped structure, with the first part 11 covering the opening side of the second part 12, so that the first part 11 and the second part 12 together define the receiving space; the first part 11 and the second part 12 can also be hollow structures with one open side, with the opening side of the first part 11 covering the opening side of the second part 12. Naturally, the box 10 formed by the first part 11 and the second part 12 can have various shapes, for example, that of a circular cylinder, a cuboid, or the like.

[0072] The battery device 100 can contain several battery cells 20, which can be connected in series, parallel, or in a mixed configuration. A mixed configuration means that several battery cells 20 are connected in series and parallel. The several battery cells 20 can be directly connected to each other in series, parallel, or a mixed configuration, and then the entire assembly consisting of the several battery cells 20 is housed in the box 10. Of course, the battery device 100 can also be a battery module formed from several battery cells 20 that are first connected in series, parallel, or a mixed configuration, and then several battery modules can be connected in series, parallel, or a mixed configuration to form a whole and housed in the box 10. The battery device 100 can also include other structures.For example, the battery device 100 can also include a bus component for establishing an electrical connection between the multiple battery cells 20. Each battery cell 20 can be a secondary battery or a primary battery, or a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited to these.

[0073] With reference to Fig. 3 is Fig. 3 A schematic structural representation of the battery cell according to one or more embodiments of the present application. The battery cell 20 denotes the smallest unit of which the battery device 100 consists. As in Fig. As shown in Figure 3, the battery cell 20 comprises a housing 21, an electrode assembly 23, and other functional components. The housing 21 includes an end cap component 211 and an outer shell 212, the outer shell 212 having an opening, and the end cap component 211 closing the opening. The end cap component 211 is a component that covers the opening of the outer shell 212 to insulate the interior of the battery cell 20 from the external environment. Regardless of the specific circumstances, the shape of the end cap component 211 can be adapted to the shape of the outer shell 212 to fit into the outer shell 212. Optionally, the end cap component 211 can be made of a material with a certain hardness and strength (e.g.,The end cap component 211 may be made of an aluminum alloy, making it less susceptible to deformation under pressure and shock loads. This results in higher structural strength for the battery cell 20 and improved safety performance. The end cap component 211 may be provided with a functional component such as an electrode terminal 211a. The electrode terminal 211a can be used for electrical connection to the electrode assembly 23 to input or output electrical energy to the battery cell 20. In some embodiments, the end cap component 211 may also be provided with a pressure relief mechanism that releases internal pressure when the internal pressure or temperature of the battery cell 20 reaches a threshold value.The end cap component 211 can also be made of various materials, for example copper, iron, aluminum, stainless steel, aluminum alloy, plastic, or the like, and the embodiments of the present application do not impose any specific restrictions in this regard. In some embodiments, an insulating element 24 may also be provided on the inside of the end cap component 211. The insulating element 24 can be used to insulate the electrical connection component inside the outer shell 212 from the end cap component 211 in order to reduce the risk of a short circuit. For example, the insulating element 24 may be made of plastic, rubber, or the like.The outer shell 212 is a component that, together with the end cap component 211, forms the inner environment of the battery cell 20. This inner environment can be used to accommodate the electrode assembly 23, the electrolyte solution, and other components. The outer shell 212 and the end cap component 211 can be separate components, and the outer shell 212 can have an opening. The inner environment of the battery cell 20 is formed by closing the opening with the end cap component 211.

[0074] The unit can also be manufactured without restriction from the end cap component 211 and the outer shell 212; specifically, the end cap component 211 and the outer shell 212 can form a common connecting surface before other components are inserted into the outer shell. If it is necessary to encapsulate the interior of the outer shell 212, the end cap component 211 is used to cover the outer shell 212. The outer shell 212 can have various shapes and sizes, for example, a cuboid shape, a circular cylindrical shape, the shape of a hexagonal prism, and the like. Specifically, the shape of the outer shell 212 can be determined according to the specific shape and size of the electrode arrangement 23.The outer shell 212 can be made of various materials, for example copper, iron, aluminum, stainless steel, aluminum alloy, plastic, or the like, and the embodiments of the present application do not impose any specific restrictions in this regard. An electrode output section (not shown) can be provided on the outer shell 212; the electrode output section serves for electrical connection to the tab 23a in order to supply or receive electrical energy from the battery cell 20.

[0075] The electrode assembly 23 is a component in the battery cell 20 in which electrochemical reactions take place. One or more electrode assemblies 23 may be contained within the outer shell 212. The electrode assembly 23 is formed mainly by winding or stacking the cathode foil and the anode foil, and typically a separator is provided between the cathode foil and the anode foil. The portions of the cathode foil and the anode foil containing active substance form the main body of the electrode assembly 23, and the portions of the cathode foil and the anode foil that do not contain active substance each form a tab 23a. The first cathode tab and the first anode tab may be located either together at one end of the main body or at two ends of the main body.During the charging and discharging process of the battery device 100, the active cathode substance and the active anode substance react with the electrolyte solution, and the tab 23a is connected to the electrode terminal 211a by the connecting element 22 to form an electrical circuit.

[0076] To solve the problem that the upper cover 111 of the box 10 of the battery device 100 generates noise and affects the environment, the present application provides a battery device 100 and a power-consuming device. In combination with and with reference to Fig. 4 and Fig. 5, shows Fig. 4 a schematic structural representation of the first part according to one or more embodiments of the present application; Fig. Figure 5 is a schematic structural overview of the first part in Fig.4. The battery device 100 comprises a box 10 and a damping layer 13. The box 10 comprises a first part 11 and a second part 12, wherein the first part 11 is connected to the second part 12, the second part 12 forming a receiving chamber with an opening, and the first part 11 is arranged around the opening. The first part 11 comprises an upper cover 111. The damping layer 13 is connected to the first part 11 and arranged on the surface of at least one side of the upper cover 111.

[0077] The first part 11 of the housing 10 primarily serves to support the battery cell 20, while the second part 12 primarily serves to cover the first part 11, thus encapsulating the battery cell 20 within the housing 10. The second part 12 is also referred to as the cover body. The top cover 111 is an important component of the second part 12; some second parts 12 may consist only of the top cover 111, while others may also have a side wall in addition to the top cover 111. The top cover 111 is positioned relative to the battery cell 20 and is generally located on the top of the housing 10. In some electric vehicles and other means of transport, the battery device 100 used is relatively large, and therefore the surface area of ​​the top cover 111 is also relatively large. Consequently, the top cover 111 is more susceptible to vibrations, which can generate noise.The damping layer 13 is a component containing a damping material. The damping layer 13 can prevent or reduce the noise generated by the upper cover 111 during vibration of the upper cover 111. The damping layer 13 can be arranged on the inner surface of the upper cover 111, on the outer surface of the upper cover 111, or simultaneously on both the inner and outer surfaces of the upper cover 111. The inner surface of the upper cover 111 is the surface of the upper cover 111 facing the first part 11, or the surface forming the interior of the box 10. The outer surface of the upper cover 111 is the surface of the upper cover 111 facing away from the first part 11 and belonging to the outer surface of the box 10. The damping layer 13 can be a large, plate-shaped structure arranged on the surface of at least one side of the upper cover 111.

[0078] By attaching a damping layer 13 to the upper cover 111 of the box 10, the first part 11 can be dampened by the damping layer 13 during vibrations, thereby reducing the noise generated by the vibration of the first part 11, thus reducing the noise generated by the battery device 100 and the environmental impact of the battery device 100.

[0079] In one possible embodiment, the damping layer 13 is glued to the upper cover 111.

[0080] The damping layer 13 can be glued to the upper cover 111 using adhesives such as double-sided adhesive tape, liquid adhesive or solid adhesive, or alternatively the damping layer 13 can be provided with an adhesive on one side to allow it to be glued to the upper cover 111.

[0081] The damping layer 13 is connected to the upper cover 111 by means of adhesive bonding, which simplifies the connection in the simplest way, speeds up the production of the battery device 100 and makes operation easier.

[0082] In one possible embodiment, the damping layer 13 comprises a rubber damping plate, a resin damping plate or an asphalt damping plate.

[0083] The damping layer 13 can be a damping plate or a damping patch. The rubber damping plate is a damping layer made of rubber 13. The rubber damping plate, such as butyl rubber patches, has good damping properties and can be applied directly, making it very easy to use. The main component of the resin damping plate is high-molecular-weight resin material. These materials generally exhibit stable physical and chemical properties and offer excellent vibration and noise reduction, heat resistance, cold resistance, aging resistance, and adhesion. They are non-irritating to the skin and do not have a corrosive effect on materials such as metal, plastic, rubber, or the like. The asphalt damping plate is made of asphalt and also exhibits good vibration and noise reduction.

[0084] Rubber damping plates, resin damping plates or asphalt damping plates are inexpensive and have a good noise reduction effect.

[0085] In one possible embodiment, the damping layer 13 is connected to the upper cover 111 by spraying.

[0086] The raw material of part of the damping layer 13 is liquid and can be sprayed onto the upper cover 111 during the production process to form the damping layer 13.

[0087] The spraying process enables a closer bond between the damping layer 13 and the first part 11, eliminating the need for any other connecting element, resulting in a simpler construction.

[0088] In one possible embodiment, the damping layer 13 comprises an aqueous acrylic liquid damping layer, an aqueous epoxy damping layer, an aqueous polyurethane damping layer, an aqueous chlorinated rubber damping layer, an aqueous vinyl ester damping layer, or an aqueous silicone damping layer.

[0089] Aqueous acrylic material, aqueous epoxy material, aqueous polyurethane material, aqueous chlorinated rubber material, aqueous vinyl ester material, or aqueous silicone material have strong adhesive properties and adhere well to the top cover 111 after application. Furthermore, they exhibit good damping properties as well as high corrosion and water resistance, making them suitable for mounting on the top cover 111 of box 10. Aqueous acrylic damping coating: a coating formulated with water as a solvent or dispersion medium, acrylic esters as a resin matrix, and various additives, fillers, and pigments. Aqueous epoxy damping coating: a coating formulated with water as a solvent or dispersion medium, epoxy resin as a resin matrix, and various additives, fillers, and pigments.Aqueous polyurethane damping coating: a coating formulated with water as a solvent or dispersion medium, polyurethane resin as the resin matrix, and various additives, fillers, and pigments. Aqueous chlorinated rubber damping coating: a coating formulated with water as a solvent or dispersion medium, chlorinated rubber resin as the resin matrix, and various additives, fillers, and pigments. Aqueous vinyl ester damping coating: a coating formulated with water as a solvent or dispersion medium, vinyl ester resin as the resin matrix, and various additives, fillers, and pigments. Aqueous silicone damping coating: a coating formulated with water as a solvent or dispersion medium, silicone resin as the resin matrix, and various additives, fillers, and pigments.

[0090] The aqueous acrylic liquid damping layer, the aqueous epoxy damping layer, the aqueous polyurethane damping layer, the aqueous chlorinated rubber damping layer, the aqueous vinyl ester damping layer or the aqueous silicone damping layer has a good noise reduction effect and is suitable for spraying.

[0091] In one possible embodiment, it is provided that several damping layers 13 are provided, which are assigned to several areas in which the vibration amplitude of the first part 11 is greatest.

[0092] The upper cover 111 can have several areas with high vibration amplitudes, so that several damping layers 13 can be provided, with each damping layer 13 being assigned to one or more areas with high vibration amplitudes. For example, if there are ten vibration areas on the upper cover 111, five of which have larger and the other five smaller vibration amplitudes, then one damping layer 13 can be provided on the five areas with larger vibration amplitudes. Five damping layers 13 can be provided, with each damping layer 13 corresponding to an area with large vibration amplitudes. Alternatively, fewer than five damping layers 13 can be provided, with at least one damping layer 13 corresponding to two or more areas with large vibration amplitudes.Alternatively, more than five damping layers 13 can be provided, with at least one area with a large vibration amplitude being equipped with multiple damping layers 13. If there are multiple areas with the largest vibration amplitude, the areas where vibrations occur in the upper cover 111 are sorted according to the magnitude of the vibration amplitude, and then several areas are selected in descending order of vibration amplitude. The magnitude of the vibration amplitude of the upper cover 111 can be determined by performing vibration simulation tests on the first part 11.

[0093] By arranging several damping layers 13, several areas with high noise levels can be covered, thereby improving the noise reduction effect.

[0094] In one possible embodiment, the thickness of the damping layer is 13 0.5 mm to 4 mm.

[0096] This thickness range is sufficient to achieve a noise reduction effect without the thickness becoming too large and affecting the thickness of the first part 11.

[0097] In one possible embodiment, the thickness of the damping layer is 13 mm to 2 mm.

[0098] The thickness of the damping layer 13 can be 1 mm, 1.1 mm, 1.2 mm, 1.25 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.75 mm, 1.8 mm, 1.9 mm or 2 mm, or any value within the range formed by any two of the above values; for example, the thickness of the damping layer 13 can be between 1.2 mm and 1.75 mm.

[0099] This thickness range exhibits a better noise reduction effect without affecting the thickness of the first part 11.

If the damping layer 13 has the shape of a triangle or a quadrilateral, the width direction of the damping layer 13 is the direction of the shortest height of the shape, and the size of the width direction of the damping layer 13 is the size of the shortest height of the shape.The size of the damping layer 13 in the width direction can be 10 mm, 11 mm, 12 mm, 15 mm, 17 mm, 19 mm, 20 mm, 22 mm, 25 mm, 28 mm, 30 mm, 35 mm or 40 mm, or any value within the range formed by any two of the above values; for example, the size of the damping layer 13 in a width direction can be between 12 mm and 28 mm.

[0102] This size makes it possible to arrange the width of the damping layer 13 in different boxes 10, thus saving space.

[0103] In one possible embodiment, the size of the damping layer 13 is 20 mm to 30 mm in the width direction.

[0104] The size of the damping layer 13 in a width direction can be 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm or 30 mm, or any value within the range formed by any two of the above values; for example, the size of the damping layer 13 in a width direction can be between 22 mm and 28 mm.

[0105] This size is better suited for arrangement on the first part 11 of box 10.

[0106] In one possible embodiment, the size of the damping layer 13 is 50 mm to 100 mm in a longitudinal direction.

[0107] The damping layer 13 can be rectangular in shape. Its length can be 50 mm, 52 mm, 55 mm, 58 mm, 60 mm, 70 mm, 80 mm, 82 mm, 85 mm, 88 mm, 90 mm, 93 mm, 95 mm, 97 mm, or 100 mm, or any value within the range formed by any two of the above values. For example, the length of the damping layer 13 can be between 58 mm and 93 mm. A damping layer 13 of this length is suitable for the housing 10 of most battery devices 100 and can effectively cover the vibration areas of the upper cover 111. The longitudinal direction of the damping layer 13 can be the longitudinal direction of the upper cover 111, the width direction of the upper cover 111 or the diagonal direction of the upper cover 111.The arrangement of the damping layer 13 can be in an array or in a “*” pattern, and is specifically designed depending on the strongly vibrating area of ​​the upper cover 111.

[0108] This size is better suited to covering the highly vibrating area of ​​the first part 11.

[0109] In one possible embodiment, the size of the damping layer 13 is 60 mm to 80 mm in the longitudinal direction.

[0110] The size of the damping layer 13 in the longitudinal direction can be 60 mm, 62 mm, 64 mm, 65 mm, 68 mm, 70 mm, 72 mm, 73 mm, 75 mm, 78 mm or 80 mm, or any value within the range formed by any two of the above values; for example, the size of the damping layer 13 in the longitudinal direction can be between 68 mm and 73 mm.

[0111] This size is better suited to cover the highly vibrating area of ​​the first part 11 and to be arranged on the first part 11 of the box 10.

[0112] To solve the aforementioned technical problems, the present application also employs the provision of a power-consuming device as yet another technical solution; the power-consuming device comprises the previously mentioned battery device 100.

[0113] By attaching a damping layer 13 to the upper cover 111 of the box 10 of the battery device 100 of the power-consuming device, the first part 11 can be dampened by the damping layer 13 during vibrations, thereby reducing the noise generated by the vibration of the first part 11, and thus reducing the noise generated by the battery device 100 and the effects of the environment in which the power-consuming device is located on the battery device 100.

[0114] Finally, in a specific application scenario, the present application provides a battery device 100 as a solution to the problem that the upper cover 111 of the housing 10 of the existing battery device 100 generates noise due to vibrations.
