[0003] In the development of battery technology, to improve the space utilization of batteries, current battery technology tends to extend the electrode assembly. However, when the electrode assembly is extended, due to its strength limitations, it often bends and deforms, leading to defects such as wrinkles, deformation, delamination, and breakage, resulting in reduced yield. To address this issue, some related technologies have proposed batteries that divide the electrode assembly into multiple electrode components to shorten the size of each individual component. However, during battery use, friction or collisions can occur between adjacent electrode components, which, in severe cases, can cause damage or short circuits, affecting battery performance and safety.

[0004] Therefore, there is an urgent need for a battery and power supply device to solve the above problems. Utility Model Content

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0055] Example 1

[0056] like Figure 1 As 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.

[0057] 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.

[0058] To prevent the electrode assembly 30 from bending or deforming, or the electrode sheets from wrinkling or breaking due to excessive length or width, the electrode assembly 30 includes multiple electrode components 31. These multiple electrode components 31 are connected in series, parallel, or mixed connection to improve the capacity and voltage of the battery 100. Mixed connection means that some of the multiple electrode components 31 are connected in series and others in parallel.

[0059] 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.

[0060] However, during the use of the battery 100, friction or collision may occur between adjacent electrode components 31. In severe cases, this may cause damage or short circuits to the electrode components 31, affecting the performance and safety of the battery 100.

[0061] To solve the above problems, such as Figures 1-3As shown, the battery 100 provided in this embodiment also includes a separator bracket 60 made of insulating material. The separator bracket 60 includes a first spacer 61 and a second spacer 62. The first spacer 61 is sandwiched between the electrode components 31 arranged along the first direction, and the second spacer 62 is sandwiched between the electrode components 31 arranged at intervals along the second direction. The first spacer 61 and the second spacer 62 are inserted into each other.

[0062] The battery 100 provided in this embodiment provides a first spacer 61 between the electrode components 31 arranged along a first direction and a second spacer 62 between the electrode components 31 arranged along a second direction. In other words, the first spacer 61 and the second spacer 62 separate the electrode components 31, preventing friction or collision between adjacent electrode components 31 during use, thereby avoiding damage or short circuits to the electrode components 31 and improving the safety and service life of the battery 100. The first spacer 61 and the second spacer 62 are interlocked, facilitating quick assembly of the first spacer 61 and the second spacer 62, while preventing displacement of the first spacer 61 and the second spacer 62 during use.

[0063] In this embodiment, the first direction is the length direction of the battery 100, the second direction is the width direction of the battery 100, and 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 can also be set at other angles. In another optional embodiment, the first direction can be the length direction of the battery 100, and the second direction can be the width direction of the battery 100.

[0064] like Figure 4 and Figure 5 As shown, the first spacer 61 includes a base plate 611 and two first side plates 612 and two second side plates 613 erected on the base plate 611. The first side plates 612 and the second side plates 613 are connected end to end in sequence and together with the base plate 611 form a cavity 6001. That is to say, the first spacer 61 is a hollow structure, so as to reduce the weight of the first spacer 61, thereby reducing the weight of the battery 100, which is conducive to realizing the lightweight design of the battery 100.

[0065] Optionally, each of the two second side plates 613 is provided with a slot 6131, and the second spacer 62 is inserted into the slot 6131. ​​The slot 6131 ensures that the second spacer 62 can be accurately aligned with the first spacer 61, ensuring that the relative positions of the first spacer 61 and the second spacer 62 in space are accurate. This is beneficial for optimizing the internal layout of the battery 100 and improving space utilization.

[0066] Optionally, each of the two second side plates 613 is provided with a clearance groove 6132. The tabs of two adjacent electrode components 31 arranged along the first direction are connected and pass through the corresponding clearance groove 6132. By providing the clearance groove 6132, the second side plate 613 provides clearance for the tabs of the electrode components 31. At the same time, the connection point of the tabs of two adjacent electrode components 31 is located between the two second side plates 613, thus providing protection for the tabs. In this embodiment, two adjacent electrode components 31 arranged along the first direction are connected in series, that is, the positive tab of one of the two adjacent electrode components 31 is connected to the negative tab of the other to increase the voltage of the electrode group 30. In other embodiments, two adjacent electrode components 31 arranged along the first direction can also be connected in parallel to increase the capacity of the electrode group 30.

[0067] like Figures 1-3 As shown, the battery 100 also includes a support frame 50, which is disposed on the outer periphery of the electrode assembly 30. When the electrode assembly 30 is inserted into the casing, the support frame 50 contacts the casing 10 to prevent the electrode assembly 30 from directly contacting the casing 10, thereby preventing damage to the electrode assembly 30 when it is inserted into the casing.

[0068] Specifically, the support frame 50 includes a third side plate 51 and a connector 52. The third side plate 51 is disposed on both sides of the electrode group 30 along the second direction, and the connector 52 is disposed on both sides of the electrode group 30 along the first direction. The connector 52 is detachably connected to the third side plate 51. The third side plate 51 and the connector 52 provide support for the four sides of the electrode group 30, preventing the electrode group 30 from being damaged by external pressure or collision. The detachable connection between the connector 52 and the third side plate 51 facilitates quick assembly and disassembly of the connector 52 and the third side plate 51.

[0069] like Figure 1 , Figure 6 and Figure 7 The connector 52 includes a first main plate 521 and a connecting portion 522. The first main plate 521 abuts against the side of the electrode assembly 30 along a first direction. The connecting portion 522 is disposed at both ends of the first main plate 521 along a second direction. The connecting portion 522 is provided with a snap-fit ​​portion 5221, and the third side plate 51 is provided with a slot 5113. The snap-fit ​​portion 5221 and the slot 5113 are inserted into each other to realize a detachable connection between the first connector 52 and the third side plate 51, thereby improving the assembly efficiency of the connector 52 and the third side plate 51. Of course, in other embodiments, the slot 5113 can be disposed on the connecting portion 522, and the snap-fit ​​portion 5221 can be disposed on the third side plate 51, which can also achieve the above effect.

[0070] Optionally, the snap-fit ​​part 5221 is provided with a guide slope 52211, so that the entire snap-fit ​​part 5221 is formed into a wedge-shaped structure. The snap-fit ​​part 5221 can be snapped into the slot 5113 along the guide slope 52211, so that the snap-fit ​​part 5221 can slide into the slot 5113 better, so as to facilitate the quick assembly of the snap-fit ​​part 5221 and the slot 5113.

[0071] Optionally, the first main body plate 521 is provided with a tab hole 5211. The positive tab of the electrode group 30 passes through the tab hole 5211 of one of the first main body plates 521 and is connected to one of the end caps 20. The negative tab passes through the tab hole 5211 of the other first main body plate 521 and is connected to the other end cap 20. The tab hole 5211 realizes the function of avoiding the positive and negative tabs of the electrode group 30.

[0072] Optionally, the connector 52 further includes a plurality of second protrusions 523, which are disposed on the outer side of the first main body plate 521. In this embodiment, the first main body plate 521 is elongated, the second protrusions 523 extend along the width direction of the first main body plate 521, and the plurality of second protrusions 523 are spaced apart along the length direction of the first main body plate 521. On the one hand, this can improve the overall strength of the first main body plate 521; on the other hand, it can form a gap between the first main body plate 521 and the end cap 20, which facilitates venting and thus improves the safety of the battery 100.

[0073] Optionally, the third side plate 51 includes a second main plate 511 and a first protrusion 512. The second main plate 511 abuts against the side of the electrode assembly 30 along the second direction. The first protrusion 512 is disposed on the outer side of the second main plate 511 and abuts against the inner wall of the housing 10. By providing the first protrusion 512, a gap can be formed between the second main plate 511 and the housing 10. This gap is conducive to venting and further improves the safety performance of the battery 100.

[0074] Optionally, there are two first protrusions 512, which are arranged at intervals along a third direction. The connecting part 522 is located between the two first protrusions 512. When the connector 52 and the third side plate 51 are assembled, the first protrusions 512 can provide guidance for the connecting part 522 to avoid the connecting part 522 from being misaligned when it is assembled with the third side plate 51, thereby further improving the assembly efficiency of the connector 52 and the third side plate 51.

[0075] like Figure 2 and Figure 3As shown, the first spacer 61 also includes a plug-in protrusion 614, which is disposed on the outer side of the first side plate 612. The support frame 50 (specifically the second main body plate 511) is provided with a plug-in groove 5111. The plug-in protrusion 614 is adapted to the plug-in groove 5111, and the plug-in protrusion 614 can be plugged into the plug-in groove 5111 to achieve a stable connection and quick assembly and disassembly of the first spacer 61 and the third side plate 51, thereby improving the assembly efficiency of the first spacer 61 and the third side plate 51.

[0076] Optionally, the cross-sectional shape of the insertion protrusion 614 is non-circular to prevent the first spacer 61 from rotating relative to the third side plate 51, thereby further improving the structural stability of the battery 100. Specifically, the non-circular shape can be elliptical or polygonal, or it can be a regular pattern formed by alternating straight lines and curves, or an irregular pattern formed by straight lines and curves, or a regular or irregular pattern formed by curves. This embodiment does not limit this.

[0077] Optionally, the third side plate 51 is made of insulating material to achieve insulation between the electrode group 30 and the inner wall of the casing 10, thereby improving the safety performance of the battery 100.

[0078] Optionally, the third side panel 51 is made by injection molding, which has high production efficiency and good product quality.

[0079] like Figure 1 and Figure 8 As shown, the end cap 20 includes a cover plate 21 and a support protrusion 22. The cover plate 21 covers the opening of the housing 10 and is elongated. The support protrusion 22 is provided on both sides of the cover plate 21 along its length and extends along the width of the cover plate 21 and abuts against the support frame 50 (specifically the first main body plate 521). 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, an exhaust channel can be formed between the cover plate 21 and the first main body plate 521 to facilitate exhaust, thereby improving the safety of the battery 100.

[0080] In addition, after the end cap 20 is assembled with the housing 10, the support protrusion 22 abuts against the first main body plate 521, eliminating the need for a separate lower plastic, simplifying the assembly process and improving the space utilization of the battery 100.

[0081] 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.

[0082] Optionally, the end cap 20 provided in this embodiment also includes an insulating sticker 23. The insulating sticker 23 is affixed to the side of the cover plate 21 facing the electrode group 30 to improve the insulation effect between the cover plate 21 and the electrode group 30. The insulating sticker 23 is relatively thin to avoid occupying more space in the housing 10, thereby improving the space utilization rate of the housing 10.

[0083] Optionally, the insulating sticker 23 has a first clearance hole 231, and the electrode tab passes through the first clearance hole 231 to avoid the insulating sticker 23 interfering with the connection between the electrode tab and the cover plate 21.

[0084] In this embodiment, the housing 10 is provided with a first explosion-proof hole 11 and a second explosion-proof hole. Explosion-proof valves are respectively installed in the first explosion-proof hole 11 and the second explosion-proof hole. When an internal energy abnormality occurs in 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 first explosion-proof hole 11 and the second explosion-proof hole, releasing the internal pressure of the housing 10, preventing the battery 100 from thermal runaway and exploding or catching fire, and improving the safety of the battery 100.

[0085] The first explosion-proof hole 11 is provided on one side of the housing 10 along the second direction, and there are two first explosion-proof holes 11, which are arranged at intervals along the first direction. The second explosion-proof hole is provided on one side of the housing 10 along the third direction. This arrangement shortens the gas path and improves exhaust efficiency. In other embodiments, the number and location of the first and second explosion-proof holes 11 can be adjusted according to actual needs.

[0086] like Figure 1 As shown, the battery 100 also includes an insulating film 40. The insulating film 40 covers the outer periphery of the electrode assembly 30 and the support frame 50 and is located inside the housing 10. After the electrode assembly 30 and the support frame 50 are assembled, the insulating film 40 is applied, and then the electrode assembly 30 and the support frame 50 covered with the insulating film 40 are installed into the housing 10. The insulating film 40 improves the insulation protection capability of the electrode assembly 30. Specifically, the insulating film 40 is a Mylar film.

[0087] Optionally, the insulating film 40 is provided with second clearance holes 41 on both sides along the first direction so that the electrode tab can extend out through the second clearance holes 41.

[0088] Optionally, the insulating film 40 is provided with slits, and the first explosion-proof hole 11 and the second explosion-proof hole are respectively positioned opposite to the slits and are provided in a one-to-one correspondence, so that the gas in the electrode group 30 can be quickly discharged through the slits.
