[0041] refer to Figure 2 , Figure 2Schematic diagram of the exploded structure of the battery 100 provided in some embodiments of the present application. The battery 100 includes a box body 101 and a battery cell 102, and the battery cell 102 is contained in the box body 101. The box body 101 includes a first box body 101a and a second box body 101b, and the first box body 101a and the second box body 101b cover each other, and the first box body 101a and the second box body 101b jointly define a storage space for accommodating the battery cell 102. The second box body 101b can be a hollow structure with one end open, and the first box body 101a can be a plate-like structure, and the first box body 101a covers the open side of the second box body 101b, so that the first box body 101a and the second box body 101b jointly define a storage space; the first box body 101a and the second box body 101b can also be hollow structures with one side open, and the open side of the first box body 101a covers the open side of the second box body 101b. Of course, the box body 101 formed by the first box body 101a and the second box body 101b can be in various shapes, such as a cylinder or a cuboid.

[0042] There may be multiple battery cells 102, and the multiple battery cells 102 may be connected in series, in parallel, or in a mixed connection. A mixed connection means that the multiple battery cells 102 are both connected in series and in parallel.

The battery 100 may also include other components. For example, the battery 100 may also include a busbar assembly for realizing electrical connection between the multiple battery cells 102.

[0043] The battery cell 102 may 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 thereto. The battery cell 102 may be cylindrical, flat, rectangular, or in other shapes.

[0044] refer to Figure 3 , Figure 3 A schematic diagram of the exploded structure of a battery cell 102 provided in some embodiments of the present application.

[0045] The battery cell 102 includes a shell 1021, an end cap 1022 and an electrode assembly 1023. The shell 1021 is determined according to the shape of one or more electrode assemblies 1023 after being combined. For example, the shell 1021 can be a hollow cuboid, a cube or a cylinder, and one of the surfaces of the shell 1021 has an opening so that one or more electrode assemblies 1023 can be placed in the shell 1021. For example, when the shell 1021 is a hollow cuboid or a cube, one of the planes of the shell 1021 is an open surface, that is, the plane does not have a shell wall so that the inside and outside of the shell 1021 are connected. When the shell 1021 is a hollow cylinder, the circular side of the shell 1021 is an open surface, that is, the circular side does not have a shell wall so that the inside and outside of the shell 1021 are connected. The end cap 1022 is connected to the shell 1021 at the opening of the shell 1021 to form a closed shell for placing the electrode assembly 1023.

[0046] The end cap 1022 is basically in the shape of a flat plate, and two poles 1024 are provided on the end cap 1022. The two poles 1024 include a positive pole 1024a and a negative pole 1024b. An explosion-proof valve 1025 may also be provided on the end cap 1022. When too much gas is generated by the battery cell 102, the gas expands and the gas pressure in the shell increases to a value exceeding a preset value, the explosion-proof valve 1025 may be cracked to connect the inside and outside of the shell, and the gas is released outward through the crack of the explosion-proof valve 1025, thereby avoiding explosion.

The isolation block 2 provides physical isolation between the positive electrode column 1024a and the negative electrode column 1024b, thereby reducing the possibility of arcing between the positive electrode column 1024a and the negative electrode column 1024b and reducing the risk of leakage between the battery cells 102. The isolation block 2 can effectively block the heat transfer between the positive electrode column 1024a and the negative electrode column 1024b, and has a fire prevention effect.

[0073] In the above embodiment, the fireproof board 1 and the isolation block 2 of the integrated structure are prepared by molding. In order to ensure the overall performance of the material, the block-shaped protrusions can be prepared separately during the molding process, and then these protrusions are embedded in the corresponding grooves during the final molding, and then pressed as a whole. This step-by-step process ensures the close combination of the components and improves the integrity and consistency of the overall structure.
