The first sealing block is configured to withstand the force and separate from one end of the through hole. The reset member connects the first sealing block and the sidewall of the fluid replenishment chamber to reset the first sealing block after the force is removed. The extension direction of the reset member intersects the axial direction of the through hole.

[0011] Optionally, the fluid replenishment chamber has an operating hole, and the sealing assembly includes a second sealing block located between the first sealing block and the operating hole, the second sealing block being able to be subjected to a force and move closer to the first sealing block.

[0012] Optionally, the battery includes a unidirectional conduction section located at one end of the through hole, which allows the liquid in the replenishment chamber to conduct unidirectionally into the cell cavity.

Detailed Implementation

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] In the embodiments of this application, directional terms such as "upper," "lower," and "side" are generally used in the following ways: Figure 1 The relative positions shown are based on the given information, and these directional terms are used only to more clearly describe the relationships between structures, not to describe absolute positions. Positions may change when the product is placed in different orientations; for example, "up" and "down" may be interchanged.

[0032] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0033] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0034] The first aspect of this application provides a battery, such as Figure 1As shown, the battery includes a housing 1 and a sealing assembly 2, wherein,

[0035] The housing 1 has a cell cavity 101 and a liquid replenishment cavity 102, which are connected by a through hole 103. The liquid replenishment cavity 102 is filled with electrolyte.

[0036] The sealing assembly 2 is located in the liquid replenishment chamber 102 and seals one end of the through hole 103. The sealing assembly 2 is configured to be able to be subjected to force so that the through hole 103 can connect the cell cavity 101 and the liquid replenishment chamber 102.

[0037] Understandably, the cell cavity 101 houses the battery cell and provides protection for it. The sealing assembly 2 seals one end of the through hole 103, separating the electrolyte in the cell cavity 101 from the electrolyte in the replenishment chamber 102, reducing the risk of decreased battery stability due to excessive electrolyte volume. When the sealing assembly 2 is subjected to force, it connects the cell cavity 101 and the replenishment chamber 102, allowing for electrolyte replenishment when the electrolyte level in the cell cavity 101 decreases, thus extending the battery's lifespan.

[0038] In the embodiments of this application, the cell cavity 101 can be used as a cavity to accommodate the cell or as a shell of the cell, so that the cell cavity 101 and the internal components form a cell.

[0039] In this embodiment, the force can refer to the force generated by an object other than the battery components, such as the force exerted by a user on the sealing assembly 2 through an object like a thin rod, or the force generated by the sealing assembly 2 itself under external triggering. For example, the sealing assembly 2 can attract an object at one end of the sealing through hole 103 through magnetic force, so that the through hole 103 can connect the cell cavity 101 and the liquid replenishment cavity 102.

[0040] In this embodiment, the electrolyte filling chamber 102 is mainly filled with electrolyte, and the amount of electrolyte inside decreases as the amount of electrolyte added to the cell cavity 101 increases.

[0041] In summary, by dividing the electrolyte into two relatively independent parts, the battery can still maintain a certain level of stability when the electrolyte volume is increased, which is beneficial to battery operation.

[0042] In some embodiments of this application, such as Figure 1 As shown, the sealing assembly 2 includes a first sealing block 21 and a reset member 22. The first sealing block 21 is movable along the extension and retraction direction of the reset member 22. The first sealing block 21 is configured to withstand the force and separate from one end of the through hole 103. The reset member 22 connects the first sealing block 21 and the side wall of the liquid replenishment chamber 102 to reset the first sealing block 21 after the force is removed. The extension direction of the reset member 22 intersects the axial direction of the through hole 103.

[0043] Understandably, when no force is applied, the first sealing block 21 can seal the end of the through hole 103, thus forming a relatively sealed cavity between the electrolyte replenishment chamber 102 and the cell cavity 101, which is beneficial to improving the stability of the cell. When a force is applied, the first sealing block 21 can release its sealing effect on the through hole 103, allowing electrolyte from the electrolyte replenishment chamber 102 to enter the cell cavity 101 and replenish electrolyte to the cell cavity 101. In addition, when no force is applied, the reset member 22 can limit the first sealing block 21, thus allowing the first sealing block 21 to seal the through hole 103; after the force is removed, the reset action of the first sealing block 21 allows it to seal one end of the through hole 103.

[0044] In this embodiment, a sealing ring can be fitted on the outside of the first sealing block 21, so that the sealing ring can form a seal on one end of the through hole 103 through deformation, which is beneficial to improve the relative sealing of the liquid replenishment chamber 102 and the cell chamber 101.

[0045] In this embodiment, the reset member 22 can be a spring, which resets the first sealing block 21 through its own elastic force.

[0046] In some embodiments of this application, such as Figure 1 As shown, the fluid replenishment chamber 102 has an operation hole 1021, and the sealing assembly 2 includes a second sealing block 23. The second sealing block 23 is located between the first sealing block 21 and the operation hole 1021, and the second sealing block 23 can be brought close to the first sealing block 21 by a force.

[0047] It is understood that the space between the first sealing block 21 and the second sealing block 23 is generally filled with electrolyte. When the second sealing block 23 is subjected to the force of an object passing through the operating hole 1021, it can move towards the first sealing block 21. This can compress the electrolyte between the first sealing block 21 and the second sealing block 23, causing the first sealing block 21 to be subjected to the force and thus separate from one end of the through hole 103, thereby replenishing the electrolyte in the cell cavity 101.

[0048] In this embodiment of the application, a sealing ring may be fitted on the outside of the second sealing block 23, making it difficult for the electrolyte between the first sealing block 21 and the second sealing block 23 to leave the replenishment chamber 102 through the operation hole 1021 after passing through the second sealing block 23.

[0049] In some embodiments of this application, such as Figure 1 As shown, the battery includes a unidirectional conduction section 3, which is located at one end of the through hole 103 and allows the liquid in the replenishment chamber 102 to conduct unidirectionally into the cell cavity 101.

[0050] It is understandable that the unidirectional conduction part 3 can prevent the first sealing block 21 located at the end of the through hole 103 from being pushed open when the electrolyte pressure in the cell cavity 101 is too high, which is beneficial to improving the electrolyte replenishment effect of the replenishment cavity 102.

[0051] In some embodiments of this application, such as Figure 1 As shown, the unidirectional conduction part 3 covers one end of the through hole 103 facing the cell cavity 101.

[0052] It is understandable that the unidirectional conductive part 3 covering the end of the through hole 103 facing the cell cavity 101 will interfere with the electrolyte in the cell cavity 101 due to its own structural characteristics. This helps to prevent the electrolyte in the cell cavity 101 from flowing back into the replenishment chamber 102.

[0053] In this embodiment, the unidirectional conductive part 3 can be a spring sheet, which utilizes its elasticity to achieve unidirectional conduction of the through hole 103. Specifically, when the electrolyte in the replenishment chamber 102 enters the cell cavity 101, the unidirectional conductive part 3 can be deformed by pressure, allowing the electrolyte to enter the cell cavity 101; when the sealing assembly 2 seals one end of the through hole 103, the pressure of the electrolyte in the cell cavity 101 on the unidirectional conductive part 3 will press it against the end of the through hole 103, thus achieving unidirectional conduction of the through hole 103.

[0054] In this embodiment, the unidirectional conduction part 3 covers one end of the through hole 103 facing the cell cavity 101, which can be achieved by using a spring sheet with an area larger than the cross-sectional area of ​​the through hole 103.

[0055] In some embodiments of this application, such as Figure 1 As shown, the unidirectional conduction section 3 includes a connecting section 31 and a flow-blocking section 32. The connecting section 31 is attached to and connected to the side wall of the cell cavity 101. The flow-blocking section 32 covers the end of the through hole 103 facing the cell cavity 101.

[0056] It is understandable that the connection of the connecting section 31 to the side wall of the cell cavity 101 can keep the flow blocking section 32 in the position of the end of the through hole 103 facing the cell cavity 101, so that when the electrolyte in the cell cavity 101 passes through the through hole 103, it will be interfered by the flow blocking section 32 and cannot flow back to the liquid replenishment chamber 102 through the through hole 103.

[0057] In this embodiment, the connecting section 31 and the flow-blocking section 32 can be manufactured by an integral molding process.

[0058] In some embodiments of this application, such as Figure 2As shown, the housing 1 includes a bottom shell 111, a partition 112 and a cover plate 113. The edge of the bottom shell 111 is connected to the edge of the cover plate 113 to form a receiving cavity. The partition 112 is located in the receiving cavity and divides the receiving cavity into a cell cavity 101 and a liquid replenishment cavity 102.

[0059] Understandably, this arrangement is beneficial for the manufacture of housing 1. When manufacturing housing 1, the partition 112 can be placed in the receiving cavity to form a connection with the bottom shell 111, and then the cover plate 113 can be placed on the bottom shell 111, so that the receiving cavity can be divided by the partition 112 to form the cell cavity 101 and the liquid replenishment cavity 102.

[0060] In this embodiment, the bottom shell 111 and the partition plate 112 can be connected by welding or other means.

[0061] In this embodiment, the bottom shell 111 and the cover plate 113 can be connected by welding or other means.

[0062] In this embodiment, the through hole 103 can be located on the partition 112 to connect the cell cavity 101 and the liquid replenishment cavity 102.

[0063] In some embodiments of this application, such as Figure 3 As shown, the housing 1 includes a cylinder 121, a first baffle 122, a second baffle 123 and a third baffle 124. The first baffle 122 and the second baffle 123 are located at both ends of the cylinder 121 and are connected to the cylinder 121. The third baffle 124 is located inside the cylinder 121 and is connected to the first baffle 122 and the second baffle 123.

[0064] Understandably, this configuration can form the shell 1 by sequentially mounting the first baffle 122, the second baffle 123 and the third baffle 124 onto the cylinder 121.

[0065] In this embodiment, the first baffle 122, the second baffle 123 and the third baffle 124 can be connected to the cylinder 121 by welding or other means.

[0066] In some embodiments of this application, such as Figure 1 As shown, the volume of the liquid replenishment chamber 102 is smaller than the volume of the cell chamber 101.

[0067] Understandably, a larger cell cavity 101 is beneficial for improving battery performance, while a smaller electrolyte filling cavity 102 can avoid the problem of insufficient stability caused by excessive electrolyte in the cell cavity 101. By rationally configuring the volume of the electrolyte filling cavity 102 and the volume of the cell cavity 101, the battery exhibits good performance and stability.
