Technical Field

[0001] This utility model relates to the field of battery technology, specifically to batteries and electrical equipment. Background Technology

[0002] In related technologies, the cover assembly of a steel-cased button cell includes terminals, a sol, and a cover plate. The cover plate and terminals are electrically connected to different electrodes within the battery cell.

[0040] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0041] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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 this utility model.

[0042] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0043] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0044] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0045] Please refer to Figures 1 to 4 As shown, this utility model discloses a battery 10, which includes a shell 100, a terminal post 200, a sol 300, and a corrosion-resistant component 400.

[0046] The outer casing 100 of this invention includes a housing 110 and a cover plate 120, which together define a receiving cavity 130 for accommodating the battery cell 500 and the electrolyte. The electrolyte is used to realize ion conduction inside the battery 10 and to provide a chemical environment for electrochemical reactions of the positive and negative electrodes of the battery cell 500.

[0047] The cover plate 120 of this invention has a first connecting surface 121 and a first channel 122. The first connecting surface 121 is located on the side of the cover plate 120 near the receiving cavity 130, and the first channel 122 penetrates the cover plate 120 and forms a first opening 123 on the first connecting surface 121. The electrode post 200 includes a body 210, which passes through the first channel 122 and has a second connecting surface 220 on the side near the receiving cavity 130. The cover plate 120 is connected to the electrode post 200 by a sol 300.

[0048] The battery 10 of this invention conducts electrical energy to the outside through the outer casing 100 and the terminals 200. When electrically connected to external devices, one of the outer casing 100 and the terminals 200 serves as the positive terminal, and the other as the negative terminal. To prevent short circuits in the battery 10, the cover plate 120 connects the terminals 200 via a sol-gel 300, thereby preventing direct contact between the terminals 200 and the outer casing 100, achieving insulation between the terminals 200 and the outer casing 100, and simultaneously fixing the terminals 200 to the outer casing 100. Without departing from the inventive concept of this invention, the sol-gel 300 is an insulating material. As a preferred embodiment, the sol-gel 300 is composed of one of the following materials: epoxy resin, polyurethane, silicone, or acrylic resin. These materials have higher adhesive strength, can better fix the terminals 200 to the cover plate 120, and enhance the overall strength of the battery 10.

[0049] In existing technologies, the electrolyte in the containment cavity can directly contact the sol, causing the sol to be slowly corroded by the electrolyte. In some technologies, a sealing ring is used to fill the gap between the casing and the terminals, preventing the electrolyte from corroding the sol. However, these solutions require adjustment of the distance between the casing and the terminals when installing the sealing ring, ensuring it fits within the gap. This high precision requirement is detrimental to battery assembly.

[0050] In view of this, please refer to Figure 3 As shown, the corrosion-resistant component 400 of this utility model is housed in the receiving cavity 130 and connected to the first connecting surface 121, and also connected to the second connecting surface 220, so that the corrosion-resistant component 400 and the body 210 together seal the first opening 123, and the sol 300 is disposed on the side of the corrosion-resistant component 400 away from the receiving cavity 130.

[0051] It should be noted that the phrase "corrosion-resistant component 400 and body 210 jointly seal the first opening 123" mentioned in this utility model means that the corrosion-resistant component 400 connected to the body 210 can, together with the body 210, seal the first opening 123 provided on the cover plate 120, thereby isolating the first channel 122 and the receiving cavity 130. The electrolyte in the receiving cavity 130 will be blocked by the corrosion-resistant component 400 or the body 210 and will not be able to enter the first channel 122 from the first opening 123. Therefore, the corrosion-resistant component 400 and the body 210 of the electrode 200 jointly seal the first opening 123, preventing the electrolyte from contacting the sol 300, and preventing the electrolyte in the receiving cavity 130 from flowing out of the receiving cavity 130 from the first opening 123 and corroding the sol 300. Furthermore, since the corrosion-resistant component 400 is connected to the first connecting surface 121 and the second connecting surface 220 near the receiving cavity 130, the corrosion-resistant component 400 does not need to cooperate with the inner wall of the first channel 122 and the side wall of the body 210, which simplifies the assembly of the battery 10.

[0052] It should be noted that this utility model does not limit the manner in which the corrosion-resistant part 400 connects to the second connecting surface 220. For example, please refer to... Figure 2 , Figure 3 , Figure 10 As shown, where Figure 10 Therefore Figure 2 The diagram shows a battery 10 viewed from below, showing only the terminal post 200, corrosion-resistant component 400, and cover plate 120. In some embodiments, the battery 10 also includes a cell 500 housed in a receiving cavity 130. The corrosion-resistant component 400 has an annular structure, with its axis parallel to the extension direction of the first channel 122. The portion of the corrosion-resistant component 400 near its axis defines a clearance hole 420 and is attached to the second connecting surface 220 of the body 210, while the portion away from its axis is attached to the first connecting surface 121, such that the corrosion-resistant component 400 and the body 210 of the terminal post 200 together close the first opening 123. The cell 500 within the receiving cavity 130 can be electrically connected to the body 210 through the clearance hole 420, thereby enabling it to transfer its electrical energy to external devices through the terminal post 200. Based on the above embodiments, those skilled in the art can replace the above-mentioned clearance hole 420 on the corrosion-resistant part 400 by setting different shaped notches, so that the battery cell 500 in the receiving cavity 130 can be electrically connected to the body 210 through the clearance hole 420.

[0053] Without departing from the inventive concept of this utility model, this utility model does not limit the type of battery 10. Battery 10 can be a button battery 10, a steel-cased battery 10, etc.

[0054] This invention does not limit the manner in which the corrosion-resistant component 400 is connected to the body 210 and the cover plate 120. In some embodiments, the corrosion-resistant component 400 is connected to the first connecting surface 121 and the second connecting surface 220 by welding.

[0055] As a preferred embodiment, in some embodiments, the corrosion-resistant component 400 has a mounting surface 410 on the side away from the receiving cavity 130, and the mounting surface 410 is bonded to the first connecting surface 121 and the second connecting surface 220. By bonding the mounting surface 410 of the corrosion-resistant component 400 to the first connecting surface 121 of the body 210 and the second connecting surface 220 of the cover plate 120, the operator can directly attach the corrosion-resistant component 400 to the body 210 and the cover plate 120 by pressing during the assembly of the battery 10. The process of installing the corrosion-resistant component 400 is relatively simple and helps to improve processing efficiency.

[0056] Without departing from the inventive concept of this utility model, those skilled in the art can adjust the shape of the mounting surface 410 of the corrosion-resistant part 400. As a preferred embodiment, the mounting surface 410 of the corrosion-resistant part 400 is a plane. The above solution helps to simplify the structure of the corrosion-resistant part 400, thereby reducing the production cost of the corrosion-resistant part 400.

[0057] It should be noted that when the mounting surface 410 of the corrosion-resistant component 400 is bonded to the first connecting surface 121 and the second connecting surface 220, the specific shape of the mounting surface 410 can be changed according to the relative positions of the first connecting surface 121 and the second connecting surface 220. For example, please refer to... Figure 6 As shown, in some embodiments, the corrosion-resistant component 400 is a thin-film structure. When not attached to the first connecting surface 121 and the second connecting surface 220, the corrosion-resistant component 400 is in a flat state, and the mounting surface 410 is a plane. When the body 210 of the pole post 200 is bonded to the cover plate 120 by the sol 300, a portion of the body 210 protrudes relative to the second connecting surface 220. The second connecting surface 220 is located below the first connecting surface 121. Therefore, when the mounting surface 410 of the corrosion-resistant component 400 is bonded to the first connecting surface 121 and the second connecting surface 220, the portion bonded to the second connecting surface 220 is recessed relative to the portion bonded to the first connecting surface 121, and the mounting surface 410 becomes a curved surface.

[0058] Further, please refer to Figure 3 As shown, in some embodiments, the first connecting surface 121 and the second connecting surface 220 are coplanar. The coplanar first connecting surface 121 and the second connecting surface 220 help improve the stability of the corrosion-resistant component 400 bonded to the body 210 and the cover plate 120, thereby helping to increase the service life of the battery 10.

[0059] Specifically, please refer to Figure 3 As shown, in some embodiments, both the first connecting surface 121 and the second connecting surface 220 are perpendicular to the vertical direction, and the first connecting surface 121 and the second connecting surface 220 are in the same position in the vertical direction, that is, the first connecting surface 121 and the second connecting surface 220 are coplanar. When the mounting surface 410 of the corrosion-resistant component 400 is bonded to the first connecting surface 121 and the second connecting surface 220, the mounting surface 410 can remain flat, which can reduce the bending of the corrosion-resistant component 400 attached to the body 210 and the cover plate 120, thereby reducing the internal stress of the corrosion-resistant component 400 due to its own bending, and reducing the risk of the corrosion-resistant component 400 falling off the body 210 and the cover plate 120 during long-term use.

[0060] This utility model does not limit the position where the cover plate 120 is connected to the pole post 200 via the sol 300. Please refer to... Figure 9As shown, in some embodiments, the sol 300 is contained in the first channel 122, and the inner wall of the first channel 122 is connected to the body 210 through the sol 300. Through this solution, the sol 300 can directly provide support to the body 210 in a direction perpendicular to the extension of the first channel 122, thereby reducing the movement of the body 210 relative to the cover plate 120 in a direction perpendicular to the extension of the first channel 122.

[0061] As a preferred option, please refer to Figures 3 to 5 As shown, in some embodiments, the cover plate 120 further has a third connecting surface 140, which is located on the side of the cover plate 120 opposite to the receiving cavity 130. The terminal post 200 also includes an extension 230, which is connected to the side of the body 210 away from the first connecting surface 121. The battery 10 has a projection plane perpendicular to the extension direction of the first channel 122. The body 210 has a first projection, and the extension 230 has a second projection, with the first projection located within the second projection. The sol 300 has an annular structure and surrounds the body 210. The side of the extension 230 near the receiving cavity 130 is connected to the third connecting surface 140 via the sol 300.

[0062] Since the electrode post 200 is connected to the third connecting surface 140 via the sol 300 through the extension 230 near the receiving cavity 130, and the extension 230 is located on the side opposite to the receiving cavity 130 relative to the cover plate 120, and the first projection of the body 210 is located within the second projection of the extension 230, the area of ​​the extension 230 in the extending direction toward the first channel 122 is larger, making it easier for external devices to be electrically connected to the electrode post 200. On the other hand, the sol 300 located between the extension 230 and the cover plate 120 can provide support for the extension 230 in the extending direction, reducing the movement of the electrode post 200 relative to the cover plate 120 in the extending direction of the first channel 122. The ring-shaped sol 300 can further seal the gap between the extension 230 and the pole post 200 cover plate 120, providing good support while reducing the entry of external substances into the first channel 122, reducing the contact between external substances and the corrosion-resistant component 400, and thus reducing the impact of external substances on the connection between the corrosion-resistant component 400, the pole post 200 and the cover plate 120.

[0063] Further, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8As shown, in some embodiments, the first channel 122 has a first mounting section 1221 and a second mounting section 1223 connected in its own extension direction. The first mounting section 1221 is located between the second mounting section 1223 and the receiving cavity 130. In a direction perpendicular to the extension direction of the first channel 122, the inner wall of the first mounting section 1221 protrudes toward the first channel 122 relative to the inner wall of the second mounting section 1223. The inner wall of the first mounting section 1221 has a third connecting surface 140 on the side away from the receiving cavity 130. The sol 300 is connected to the inner wall surface of the second mounting section 1223 on the side away from its own axial direction.

[0064] Through the above scheme, the extension 230 is connected to the inner wall of the first mounting section 1221 via the sol 300 and accommodated in the second mounting section 1223. This allows the extension 230 of the electrode post 200 to utilize the space of the first channel 122, reducing the protrusion of the electrode post 200 relative to the cover plate 120 in the direction away from the receiving cavity 130, thus increasing the flatness of the outer side of the battery 10. On the other hand, the sol 300 is connected to the inner wall of the second mounting section 1223 on the side away from its own axial direction. This allows the inner wall of the second mounting section 1223 to apply a supporting force perpendicular to the axial direction of the first channel 122 to the sol 300, thereby reducing the movement of the sol 300 relative to the cover plate 120 in the axial direction perpendicular to the first channel 122, reducing the movement of the electrode post 200 connected to the sol 300 relative to the cover plate 120, and increasing the stability of the battery 10.

[0065] Further, please refer to Figure 3 , Figure 4 As shown, in some embodiments, the cover plate 120 further includes a positioning part 150, which is connected to the third connecting surface 140 and has a positioning surface 151 on the side away from the axis of the first channel 122. The sol 300 is connected to the positioning surface 151 on the side closer to its own axis. With the above solution, the sol 300 is connected to the inner wall surface of the second mounting section 1223 on the side closer to its own axis. The inner wall surface of the second mounting section 1223 can apply a supporting force perpendicular to the axis of the first channel 122 to the sol 300, thereby reducing the movement of the sol 300 relative to the cover plate 120 in the axis perpendicular to the first channel 122, reducing the movement of the electrode post 200 connected to the sol 300 relative to the cover plate 120, and increasing the stability of the battery 10.

[0066] Please refer to Figure 3 , Figure 4 , Figure 7 , Figure 8As shown, in some embodiments, the first channel 122 has a first mounting section 1221 and a second mounting section 1223 connected in its extending direction, with the first mounting section 1221 being closer to the receiving cavity 130 than the second mounting section 1223; in a direction perpendicular to the extending direction of the first channel 122, the inner wall of the first mounting section 1221 protrudes towards the first channel 122 relative to the inner wall of the second mounting section 1223, and the inner wall of the first mounting section 1221 has a third connecting surface 140 on the side away from the receiving cavity 130, and the sol 300 is connected to the inner wall surface of the second mounting section 1223 on the side away from its own axial direction. The cover plate 120 also includes a positioning part 150, which is connected to the third connecting surface 140 and has a positioning surface 151 on the side away from the axis of the first channel 122, and the sol 300 is connected to the positioning surface 151 on the side near its own axial direction.

[0067] Through the above scheme, the inner wall surface of the second mounting section 1223 and the positioning surface 151 of the positioning part 150 can provide the sol 300 with a supporting force perpendicular to the extension direction of the first channel 122, thereby further reducing the movement of the sol 300 relative to the cover plate 120 in the axial direction perpendicular to the first channel 122, reducing the movement of the electrode post 200 connected to the sol 300 relative to the cover plate 120, and increasing the stability of the battery 10.

[0068] Further, please refer to Figure 5 As shown, in some embodiments, the first mounting section 1221 forms a second opening 1222 on the third connecting surface 140. The sol 300 has a third projection on the projection plane, and the outline of the second opening 1222 has a fourth projection on the projection plane, with a gap between the third and fourth projections. When the corrosion-resistant component 400 detaches from the body 210 or the cover plate 120 due to extreme conditions, the electrolyte in the receiving cavity 130 can enter the first mounting section 1221 along the extension direction of the first channel 122 and enter the second mounting section 1223 through the second opening 1222. Since there is a gap between the fourth and third projections, the electrolyte entering the second mounting section 1223 is less likely to come into contact with the sol 300, thereby reducing the risk of electrolyte corrosion of the sol 300 and helping to extend the service life of the battery 10.

[0069] Without departing from the inventive concept of this utility model, those skilled in the art can choose the material of the corrosion-resistant component 400 to achieve the corrosion-resistant function. Furthermore, in some embodiments, the corrosion-resistant component 400 is made of polyimide, polyester, or polytetrafluoroethylene. These materials all possess strong chemical stability and can effectively resist the corrosion of the electrolyte, thereby providing better protection for the sol 300.

[0070] This utility model also proposes an electrical device, including a battery 10 as described in any of the above embodiments. In the above embodiments, the corrosion-resistant component 400, by connecting the first connecting surface 121 and the second connecting surface 220, allows the corrosion-resistant component 400 and the body 210 of the electrode post 200 to jointly seal the first opening 123, preventing the electrolyte in the receiving cavity 130 from flowing out of the receiving cavity 130 through the first opening 123 and corroding the sol 300.
