[0054] Example 1

[0055] like Figure 1As shown, this embodiment provides a battery 100, which includes a housing 10 and an electrode assembly 30. The electrode assembly 30 is disposed within the housing 10, and the housing 10 serves to support and protect the electrode assembly 30. The housing 10 can be made of plastic or metal. When the housing 10 is made of metal, it has better heat dissipation performance, higher strength, and can provide support itself.

[0056] In this embodiment, the housing 10 has openings at both ends along the first direction. The battery 100 also includes two end caps 20, which are respectively placed over the corresponding openings. The electrode assembly 30 is connected to the end caps 20, and the end caps 20 are connected to the main body of the external electrical device, thereby enabling the battery 100 to supply power to the main body of the electrical device. In other embodiments, the number of end caps 20 may be one, with one opening in the housing 10 and the end cap 20 covering the opening. In this embodiment, the first direction is the length direction of the housing 10.

[0057] In the current technology, in order to improve the capacity of batteries, current batteries are developing towards making the electrode assembly longer / wider. Since the electrode assembly is usually housed in the casing, when the electrode assembly is too long / wide, it is easy for the electrode assembly to collide with the casing during the insertion process, resulting in damage. The electrode assembly is difficult to insert into the casing. In addition, there is a gap between the electrode assembly and the inner wall of the casing, which causes the electrode assembly to shake inside the casing during battery use, which can easily cause the electrode assembly to deform and be damaged, and the tabs to break.

[0058] To solve the above problems, such as Figure 1 As shown, the battery 100 provided in this embodiment also includes a support frame 50. The support frame 50 includes a first support member 51 and a second support member 52 disposed opposite to each other. The first support member 51 and the second support member 52 are detachably connected. The first support member 51 and the second support member 52 together form a receiving cavity 5001. The electrode group 30 is disposed in the receiving cavity 5001, and the support frame 50 is disposed in the housing 10.

[0059] By placing the electrode assembly 30 within the receiving cavity 5001 formed by the first support member 51 and the second support member 52, that is, by providing the first support member 51 and the second support member 52 on the side of the electrode assembly 30, when the electrode assembly 30 is inserted into the housing, the first support member 51 and the second support member 52 contact the housing 10, avoiding direct contact between the electrode assembly 30 and the housing 10, thereby preventing damage to the electrode assembly 30 when it is inserted into the housing; and by fixing the electrode assembly 30 with the first support member 51 and the second support member 52, the electrode assembly 30 is prevented from shaking within the receiving cavity 5001, improving the structural stability of the battery 100 and extending the service life of the battery 100; in addition, the first support member 51 and the second support member 52 are detachable, facilitating the assembly and disassembly of the first support member 51 and the second support member 52, thereby improving the assembly efficiency of the battery 100.

[0060] like Figure 1 and Figure 2 As shown, the electrode assembly 30 includes two electrode components 31 arranged along the second direction. By dividing the electrode assembly 30 into two electrode components 31, the size of a single electrode component 31 in the second direction can be shortened, avoiding bending deformation, wrinkling, or breakage of the electrode sheet due to excessive length or width. In other embodiments, the number of electrode components 31 can be three, four, or more, and multiple electrode components 31 can be connected in series, parallel, or mixed to improve the capacity and voltage of the battery 100. Mixed connection refers to multiple electrode components 31 being connected in both series and parallel configurations.

[0061] In this embodiment, the second direction is the width direction of the battery 100, meaning that the first direction is perpendicular to the second direction. In other embodiments, the first and second directions may also be set at other angles. In another embodiment, the first direction may also be the width direction of the battery 100, and the second direction may also be the length direction of the battery 100.

[0062] The electrode component 31 in this application can be formed by winding or by stacking. Generally, the electrode component 31 includes at least a positive electrode, a separator, and a negative electrode.

[0063] Optionally, the support frame 50 also includes a partition 53, which is disposed between two adjacent pole group components 31 to prevent short circuits between the two adjacent pole group components 31.

[0064] Optionally, the first support member 51 is provided with a first fixing groove 5101, and / or the second support member 52 is provided with a second fixing groove 5201. At least a portion of the pole group 30 is disposed in the first fixing groove 5101; at least a portion of the pole group 30 is disposed in the second fixing groove 5201. By disposing at least a portion of the pole group 30 in the first fixing groove 5101 and the second fixing groove 5201, the support and fixing effect of the support frame 50 on the pole group 30 is improved, and the pole group 30 is prevented from coming out of the support frame 50.

[0065] like Figures 1-4As shown, the first support member 51 includes a first side plate 511, a first connecting part 512, and a first fixing part 513. The first side plate 511 abuts against the electrode assembly 30 and the inner wall of the housing 10. The first connecting part 512 is disposed on both sides of the first side plate 511 along the length direction (first direction). The first connecting part 512 is detachably connected to the second support member 52. The first fixing part 513 is disposed on both sides of the first side plate 511 along the width direction (third direction). The first side plate 511, the first connecting part 512, and the first fixing part 513 together form a first fixing groove 5101, which can prevent the electrode assembly 30 from shaking, shifting, or even colliding during use, and reduce the impact and compression of the electrode assembly 30 by external factors.

[0066] The third direction is the thickness direction of the battery 100. That is, the first direction, the second direction and the third direction are perpendicular to each other. In other embodiments, the first direction, the second direction and the third direction are set at other included angles.

[0067] Optionally, the first side plate 511, the first connecting part 512, and the first fixing part 513 are integrally formed to reduce the number of parts, simplify the assembly process, and make installation easier. Optionally, the first support member 51 is made by injection molding, which has high production efficiency and good product quality.

[0068] Optionally, the second support member 52 includes a second side plate 521, a second connecting part 522, and a second fixing part 523. The second side plate 521 abuts against the electrode assembly 30 and the inner wall of the housing 10. The second connecting part 522 is disposed on both sides of the second side plate 521 along the length direction (first direction). The second connecting part 522 is detachably connected to the first support member 51 (specifically the first connecting part 512). The second fixing part 523 is disposed on both sides of the second side plate 521 along the width direction (third direction). The second side plate 521, the second connecting part 522, and the second fixing part 523 together form a second fixing groove 5201, which can further prevent the electrode assembly 30 from shaking, shifting, or even colliding during use, and reduce the impact and compression of the electrode assembly 30 by external factors.

[0069] Optionally, the second side plate 521, the second connecting part 522, and the second fixing part 523 are integrally formed to reduce the number of parts, simplify the assembly process, and make installation easier. Optionally, the second support member 52 is made by injection molding, which has high production efficiency and good product quality.

[0070] Optionally, the first connecting portion 512 is provided with a connecting hole 5121, and the second connecting portion 522 is provided with a connecting post 5221. The connecting post 5221 is inserted into the connecting hole 5121 to achieve a detachable connection between the first support member 51 and the second support member 52, facilitating quick assembly and disassembly of the first support member 51 and the second support member 52. In other embodiments, the first support member 51 and the second support member 52 can also be detachably connected by means of snap-fit ​​or plug-in connection.

[0071] Optionally, the dimensions of the support frame 50 along the second direction are adjustable to adjust the dimensions of the receiving cavity 5001 in the second direction, enabling it to adapt to pole groups 30 of different sizes and improving the versatility of the support frame 50. Specifically, there are multiple connecting holes 5121, which are spaced apart along the width direction (second direction) of the support frame 50. The connecting post 5221 can be inserted into any of the connecting holes 5121 to adjust the dimensions of the support frame 50 in the second direction, making the operation simple and convenient.

[0072] Optionally, there may be multiple connecting posts 5221, and the spacing between two adjacent connecting posts 5221 is equal to the spacing between two adjacent connecting holes 5121, so as to improve the connection stability of the first connecting part 512 and the second connecting part 522.

[0073] Optionally, a first recess 5122 is provided on the first connecting portion 512, and / or a second recess 5222 is provided on the second connecting portion 522. At least a portion of the second connecting portion 522 (the portion provided with the connecting post 5221) is disposed in the first recess 5122, and at least a portion of the first connecting portion 512 (the portion provided with the connecting hole 5121) is disposed in the second recess 5222, so as to reduce the space occupied by the first connecting portion 512 and the second connecting portion 522 in the first direction and improve the space utilization of the battery 100.

[0074] Optionally, the support frame 50 has tab holes 5002 on both sides along the first direction. The positive and negative tabs of the electrode assembly 30 pass through the corresponding tab holes 5002 and are connected to the corresponding end caps 20, respectively. The tab holes 5002 provide a clearance function for the positive and negative tabs. Specifically, the first connecting part 512 is provided with a first split hole 5123, and the second connecting part 522 is provided with a second split hole 5223. When the first connecting part 512 and the second connecting part 522 are assembled, the first split hole 5123 and the second split hole 5223 together form the tab hole 5002.

[0075] Optionally, the support frame 50 further includes a protrusion structure 54, which is disposed on the first connecting portion 512 and / or the second connecting portion 522 and abuts against the end cap 20. The protrusion structure 54 extends along a third direction, and multiple protrusion structures 54 are arranged at intervals along a second direction. On the one hand, this can improve the overall strength of the support frame 50; on the other hand, it can form a gap between the support frame 50 and the end cap 20, which facilitates venting and thus improves the safety of the battery 100.

[0076] like Figure 1 , Figure 5 and Figure 6 As shown, the end cap 20 includes a cover plate 21, which covers the opening of the housing 10. Optionally, the cover plate 21 is made of plain aluminum sheet. Plain aluminum sheet has advantages such as easy processing and forming, light weight, and good thermal conductivity.

[0077] Optionally, the end cap 20 also includes a support protrusion 22. The cover plate 21 is elongated, and the support protrusion 22 is disposed on both sides of the cover plate 21 along its length. The support protrusion 22 extends along the width of the cover plate 21 and abuts against the support frame 50. By providing the support protrusion 22 on the cover plate 21, on the one hand, the strength of the cover plate 21 in the width direction can be improved, the deformation resistance of the cover plate 21 can be improved, and the deformation of the cover plate 21 can be avoided. On the other hand, a gap can be formed between the cover plate 21 and the support frame 50, which facilitates venting and thus improves the safety of the battery 100.

[0078] Optionally, the cover plate 21 is provided with an explosion-proof hole 211, and an explosion-proof valve is installed in the explosion-proof hole 211. When an abnormality occurs inside the battery 100, the gas pressure inside the housing 10 reaches the explosion-proof threshold of the explosion-proof valve, the explosion-proof valve opens, and the gas is discharged from the explosion-proof hole 211, releasing the internal pressure of the housing 10, preventing the battery 100 from thermal runaway and exploding and catching fire, and improving the safety of the battery 100.

[0079] like Figure 1 As shown, the battery 100 also includes an insulating film 40, which is a flat plate structure. The insulating film 40 is attached to both sides of the electrode assembly 30 along a third direction and is located on the outside of the support frame 50. The insulating film 40 improves the insulation protection capability of the electrode assembly 30. Specifically, the insulating film 40 is a Mylar film.
