In the description of the utility model, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0037] Next, with reference to the drawings, the heat absorption assembly 1 according to the embodiment of the utility model is described.

[0038] It should be noted that, as shown in Figure 1 The battery assembly 100 includes the heat absorption assembly 1 and a plurality of battery monomers 2, the plurality of battery monomers 2 are sequentially arranged along the thickness direction, the heat absorption assembly 1 is installed between adjacent battery monomers 2 and the two sides are respectively attached with the battery monomer 2, when the battery monomer 2 occurs thermal runaway, the heat absorption assembly 1 can delay or even prevent the diffusion of heat, to protect the adjacent battery monomer 2, improve the safety of the battery assembly 100.

[0039] As shown in Figures 1-5 The heat absorption assembly 1 according to the embodiment of the utility model includes: an outer package 11, a heat absorption member 12 and a breathable member 13, the outer package 11 is provided with a pressure relief part 111, and the outer package 11 is formed with a sealed cavity, the pressure relief part 111 is configured to discharge the gas in the sealed cavity when the pressure of the sealed cavity is greater than the set pressure; the heat absorption member 12 is arranged in the sealed cavity; the breathable member 13 is arranged in the outer package 11 and is correspondingly arranged with the pressure relief part 111 to block the liquid and / or solid from flowing out of the outer package 11.

[0040] Thus, the liquid heat-absorbing material and / or the solid heat-absorbing material in the sealed cavity can be blocked from flowing out of the outer package 11 through the pressure relief channel 113, so that the heat-absorbing member 12 can more fully absorb heat, thereby ensuring the heat-absorbing performance of the heat-absorbing assembly 1.

[0041] First, as shown in Figures 2-3 The heat-absorbing assembly 1 includes an outer package 11 and a heat-absorbing member 12. The outer package 11 has a sealed cavity formed therein. A pressure relief portion 111 is formed at a weak portion of the outer package 11. The pressure relief portion 111 is configured to form a pressure relief channel 113 when the pressure in the sealed cavity is greater than a set pressure. The pressure relief channel 113 is configured to communicate the sealed cavity with the outside of the outer package 11, so that the fluid in the sealed cavity can be discharged out of the outer package 11 through the pressure relief channel 113.

[0042] The heat-absorbing member 12 is arranged in the sealed cavity. The heat-absorbing member 12 can be used to absorb heat of the battery cell 2 when the battery cell 2 has thermal runaway in the battery assembly 100, so as to delay the spread of heat. At least part of the heat-absorbing member 12 can be a gaseous heat-absorbing material or a phase change material capable of being converted into a gaseous state. In this way, during the heat-absorbing process of the heat-absorbing member 12, the volume of the gaseous heat-absorbing member 12 can expand to increase the pressure in the sealed cavity, so that the pressure in the sealed cavity is greater than the set pressure. The sealed cavity can be communicated with the outside through the pressure relief channel 113 to diffuse heat and pressure outward, thereby preventing the heat-absorbing member 12 from exploding or deforming.

[0043] The heat-absorbing assembly 1 further includes a gas-permeable member 13. The gas-permeable member 13 is arranged on the outer package 11, for example, by being adhered or heat-welded to the outer package 11. The gas-permeable member 13 is arranged opposite to the pressure relief portion 111. When the pressure relief portion 111 forms the pressure relief channel 113, the gas-permeable member 13 can be used to filter the pressure relief channel 113, so as to block the liquid and / or the solid from flowing out of the outer package 11. Through the above arrangement, the liquid heat-absorbing material and / or the solid heat-absorbing material can be prevented from flowing out of the sealed cavity, so that the heat-absorbing member 12 can fully absorb heat.

[0044] The heat-absorbing assembly 1 according to the embodiments of the present application can block the liquid heat-absorbing material and / or the solid heat-absorbing material in the sealed cavity from flowing out of the outer package 11 through the pressure relief channel 113, so that the heat-absorbing member 12 can more fully absorb heat, thereby ensuring the heat-absorbing performance of the heat-absorbing assembly 1.

[0045] The air-permeable member 13 may, for example, be a liquid-proof air-permeable film. Since the solid particles in the sealed cavity of the heat absorption assembly 1 are much larger than the gas molecules, the liquid-proof air-permeable film can effectively prevent the solid particles from passing through while preventing the liquid from passing through. The liquid may, for example, be water or a non-water liquid, and the specific liquid may be determined according to the composition of the heat absorption material. For example, if the heat absorption member 12 mainly comprises a hydrogel containing water, a crystalline hydrated salt, or the like, the air-permeable member 13 may, for example, be a water-proof air-permeable member. If the heat absorption member 12 mainly comprises paraffin, the air-permeable member 13 may, for example, be an air-permeable member that prevents liquid paraffin from passing through. Alternatively, the air-permeable member 13 may, for example, be a high-molecular film that does not block the liquid and can permeate the gas. Since the solid particles in the sealed cavity of the heat absorption assembly 1 are much larger than the gas molecules, the air-permeable member 13 can effectively prevent the solid particles from passing through when the air-permeable hole is small. The air-permeable film 132 may, for example, be a high-molecular film with corresponding functions selected from the prior art.

[0046] In some embodiments of the present application, the heat absorption member 12 comprises a phase change material member, and the phase change material member comprises a phase change material. The phase change material can be converted into a gaseous state after absorbing heat. The heat absorption member 12 converted into a gaseous state can be discharged from the pressure relief channel 113, thereby reducing the temperature and pressure of the heat absorption assembly 1. Thus, the heat absorption assembly 1 can absorb more heat, and the heat absorption performance of the heat absorption assembly 1 is improved. The phase change process of some of the phase change materials is "solid state -> liquid state -> gaseous state". When the battery is in thermal runaway and rapidly heats up, the phase change material can be converted from a solid state to a liquid state and a gaseous state to absorb heat. The gaseous material will break through the weak area of the encapsulation layer and be released outward. However, the gaseous material will take away the liquid and / or solid material during the release process, which will reduce the actual material participating in heat absorption, and some of the phase change materials do not undergo a complete phase change process. Through the present application, the gaseous material can be prevented from taking away the liquid and / or solid material during the release process, and the heat absorption capacity of the heat absorption member is improved.

[0047] It should be noted that the phase change material member may, for example, comprise paraffin, stearic acid, alcohol, and a crystalline hydrated salt group. In some embodiments, the heat absorption member 12 further comprises a skeleton for maintaining the shape of the heat absorption member 12 as a whole, and the phase change material is filled in the gaps in the skeleton.

[0048] In some embodiments of the present application, as shown in Figure 4 As shown in FIG. 1, the air-permeable member 13 is arranged on the outside of the outer package 11, and the air-permeable member 13 is used to cover the pressure relief portion 111 to be arranged at the outflow end of the pressure relief channel 113.

[0049] It should be noted that a deformation space is reserved between the pressure relief portion 111 and the air-permeable member 13. When the pressure relief portion 111 is impacted by the gas pressure of the sealed cavity, the pressure relief portion 111 can be deformed towards the deformation space to form the pressure relief channel 113. The deformation space is used to accommodate the deformed pressure relief portion 111 to avoid the air-permeable member 13 from hindering the deformation of the pressure relief portion 111.

[0050] It can be understood that by arranging the air permeable member 13 outside the outer package 11, the installation difficulty of the air permeable member 13 can be reduced, and the processing difficulty of the heat absorption assembly 1 is reduced.

[0051] In some embodiments of the present application, as shown in Figure 2 It can be understood that by arranging the air permeable member 13 inside the sealed cavity and adjacent to the pressure relief portion 111, the air permeable member 13 can be located inside the pressure relief portion 111. Through the above arrangement, when the pressure relief portion 111 is impacted by the gas in the sealed cavity and deforms outwardly, the deformation of the pressure relief portion 111 caused by the air permeable member 13 can be avoided, and the installation stability of the air permeable member 13 can be improved, and the blocking effect of the air permeable member 13 is improved.

[0052] In some embodiments of the present application, the air permeable member 13 includes an installation frame 131 and an air permeable film 132, the installation frame 131 is a hollow structure and is provided with an exhaust port, the installation frame 131 is installed on the outer package 11, and the air permeable film 132 is arranged in the installation frame 131 and covers one side of the pressure relief portion 111 away from or close to the sealed cavity.

[0053] For example, as shown in Figures 2-4 The air permeable member 13 includes an installation frame 131 and an air permeable film 132, the installation frame 131 is a hollow structure, the installation frame 131 is connected with the outer package 11, and the installation frame 131 can be located on one side of the pressure relief portion 111 away from the sealed cavity or close to the sealed cavity.

[0054] The installation frame 131 is provided with an exhaust port, the exhaust port is arranged opposite to the pressure relief portion 111, and the exhaust port is used for communicating with the pressure relief channel 113, so that the fluid discharged from the pressure relief channel 113 can flow through the exhaust port. The air permeable film 132 is arranged in the installation frame 131, so that the liquid-proof air permeable film can cover one side of the pressure relief portion 111 away from or close to the sealed cavity, so that the air permeable film 132 can be used for filtering the fluid flowing through the pressure relief channel 113, thereby preventing the liquid and / or solid from flowing out of the outer package 11.

[0055] Exemplarily, the installation frame 131 can be constructed as a ring, and the cavity of the installation frame 131 is formed as an exhaust hole; or the installation frame 131 can be formed as a box, and the exhaust holes are respectively arranged on the two end walls of the installation frame 131 along the extension direction of the pressure relief channel 113.

[0056] It can be understood that by arranging the installation frame 131, the air permeable member 13 can be more easily connected with the outer package 11, the installation difficulty of the air permeable member 13 is reduced, and the installation frame 131 can also be used for supporting the air permeable film 132, so as to improve the installation stability of the air permeable film 132, thereby improving the filtering effect of the air permeable film 132.

[0057] In some embodiments of the utility model, the material of the mounting frame 131 can be the same as that of the outer package 11, or the material of the mounting frame 131 can be different from that of the outer package 11. Thus, different working conditions can be met.

[0058] In some embodiments of the utility model, as shown in Figure 2 and Figure 4 , a mounting groove 112 can be arranged on the side wall of the outer package 11, the mounting groove 112 is opposite to the pressure relief part 111 and is matched with the mounting frame 131, and the mounting frame 131 can be arranged in the mounting groove 112 to be fixed on the outer package 11.

[0059] Exemplarily, as shown in Figure 4 , the mounting groove 112 can be arranged on the outer side wall 11a of the outer package 11, and the mounting frame 131 is arranged in the mounting groove 112 to fix the air permeable member 13 on the outer side of the pressure relief part 111; or as shown in Figure 2 , the mounting groove 112 can be arranged on the inner side wall 11b of the outer package 11, and the mounting frame 131 is arranged in the mounting groove 112 to fix the air permeable member 13 on the inner side of the pressure relief part 111. Thus, the installation stability of the air permeable member 13 can be improved, the space can be fully utilized, the overall size of the heat absorption assembly 1 can be reduced, and the design rationality of the heat absorption assembly 1 is improved.

[0060] In some embodiments of the utility model, as shown in Figure 3 , the projection of the inner circumferential wall of the mounting frame 131 along the extension direction of the pressure relief channel 113 can enclose an area larger than the cross-sectional area of the pressure relief channel 113, so that the air permeable film 132 arranged in the mounting frame 131 can completely cover the pressure relief channel 113, so that the fluid flowing out of the pressure relief channel 113 needs to flow through the air permeable film 132.

[0061] Through the above arrangement, the filtering effect of the air permeable film 132 on the pressure relief channel 113 can be ensured, and the practicability of the air permeable film 132 is improved.

[0062] In some embodiments of the utility model, air permeable holes can be formed on the air permeable film 132, the air permeable holes are arranged in multiple, the multiple air permeable holes are arranged at intervals, the air permeable holes are communicated with the pressure relief channel 113, and the air permeable holes are used for flowing gas, so that the gaseous heat absorption member can flow out to the outer side of the outer package 11 through the air permeable film 132. The diameter of the air permeable hole can be 0.1 μm-20 μm, for example, 0.5 μm, 1 μm, 5 μm, 10 μm, 15 μm, etc.

[0063] It can be understood that by setting the diameter of the air vent hole to the above range, the liquid heat absorption member can be effectively prevented from flowing out of the pressure relief channel 113, and the discharge efficiency of the gaseous heat absorption member can be ensured, thereby improving the design rationality of the heat absorption assembly 1.

[0064] In some embodiments of the present application, the wall thickness of a portion of the side wall of the outer packaging member 11 can be set to be smaller than that of the adjacent portion to define the pressure relief portion 111. It should be noted that the side wall of the outer packaging member 11 can be the top wall (i.e. the wall at the top of the heat absorption assembly 1 in the application scenario) or the peripheral wall (i.e. the wall at the side of the heat absorption assembly 1 in the application scenario) of the outer packaging member 11.

[0065] Exemplarily, as shown in Figure 2 a thickness-reducing groove 114 can be machined on the side wall of the outer packaging member 11, such as by cutting or other machining methods, so that the wall thickness of the portion of the outer packaging member 11 corresponding to the thickness-reducing groove 114 is smaller than that of the adjacent portion, so that the groove bottom of the thickness-reducing groove 114 can form the pressure relief portion 111. In this way, the forming difficulty of the pressure relief portion 111 can be reduced.

[0066] In some embodiments of the present application, as shown in Figure 2 the pressure relief portion 111 can be arranged at the upper portion of the outer packaging member 11. The upper portion of the outer packaging member 11 can refer to the top wall of the outer packaging member 11, or the position of the peripheral wall adjacent to the top wall.

[0067] Through the above arrangement, when the pressure relief portion 111 forms the pressure relief channel 113, the liquid heat absorption member can be prevented from blocking the pressure relief channel 113 to cause the air permeable member 13 to fail, thereby improving the reliability of the air permeable member 13 and the design rationality of the heat absorption assembly 1.

[0068] Further, the pressure relief portion 111 can be arranged at the top wall of the outer packaging member 11. In this way, the air permeable film 132 can be better protected, thereby improving the working stability of the heat absorption assembly 1.

[0069] In some embodiments of the present application, the pressure relief portion 111 can be arranged in multiple numbers, and the multiple pressure relief portions 111 are arranged at intervals, and each pressure relief portion 111 corresponds to an air permeable member 13. Exemplarily, the pressure relief portion 111 can be arranged in two numbers, and the two pressure relief portions 111 are arranged at opposite sides of the outer packaging member 11 along the length direction, and the outer packaging member 11 is provided with an air permeable member 13 corresponding to each of the two pressure relief portions 111.

[0070] Through the above arrangement, the plurality of pressure relief portions 111 can collectively exhaust, improving the exhaust efficiency of the heat absorption assembly 1, avoiding damage to the gas permeable membrane 132 caused by excessive air pressure in the sealed cavity, and when the heat absorption assembly 1 is locally overheated, the pressure relief portion 111 of the corresponding area can form a pressure relief channel 113 to timely exhaust the gaseous heat absorption member 12, avoiding excessive air pressure in the sealed cavity to cause the outer package member 11 to have a breach, and improving the working stability of the heat absorption assembly 1.

[0071] The utility model also proposes a battery assembly 100. The battery assembly 100 can be a battery pack or a battery module.
