[0054] Example 1

[0055] like Figure 1 and Figure 2 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.

[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 prior art, the electrode assembly is prone to collision with the inner wall of the casing during the insertion process, which can lead to damage. In addition, the battery may be subjected to various external forces during use, such as vibration and collision, which can cause the electrode assembly to shift, deform or break during use, resulting in safety hazards.

[0058] To solve the above problems, such as Figures 1-4 As shown, the battery 100 provided in this embodiment also includes a support frame 40. The support frame 40 includes a top plate 44, a bottom plate 43, and a side plate 41. The top plate 44 is disposed on one side of the electrode assembly 30 along the thickness direction (third direction), the bottom plate 43 is disposed on the other side of the electrode assembly 30 along the thickness direction, and the side plate 41 is disposed on both sides of the electrode assembly 30 along the width direction (second direction). The bottom plate 43 is connected to the side plate 41, and the top plate 44 is detachably connected to the side plate 41. The support frame 40 is disposed inside the housing 10.

[0059] By providing a bottom plate 43 and a top plate 44 on both sides of the electrode assembly 30 along its thickness direction (i.e., the bottom plate 43 and top plate 44 are respectively located on the largest side of the electrode assembly 30), and by providing side plates 41 on both sides of the electrode assembly 30 along its width direction, the four sides of the electrode assembly 30 are supported and protected, increasing the structural strength of the battery 100. This allows the electrode assembly 30 to better resist deformation, preventing displacement or deformation within the housing 10, ensuring the electrode assembly 30 maintains its correct position during use, and extending the service life of the battery 100. Simultaneously, when the electrode assembly 30 is inserted into the housing, the support frame 40 contacts the housing 10, preventing direct contact between the electrode assembly 30 and the housing 10, thus avoiding damage during insertion. The top plate 44 and side plates 41 are detachably connected, facilitating rapid assembly of the top plate 44 and side plates 41, thereby improving the assembly efficiency of the battery 100.

[0060] 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.

[0061] In this embodiment, the base plate 43 and the side plate 41 are integrally injection molded, which results in high production efficiency and more uniform overall strength without any seams.

[0062] like Figures 1-3 , Figure 5 and Figure 6 As shown, the support frame 40 also includes a connector 42, which is disposed on both sides of the pole group 30 along the first direction. The connector 42 is detachably connected to the side plate 41 and abuts against the end cover 20. The detachable connection between the connector 42 and the side plate 41 facilitates quick assembly and disassembly of the connector 42 and the side plate 41.

[0063] The connector 42 includes a second main body plate 421 and a connecting portion 422. The second main body plate 421 abuts against the side of the electrode assembly 30 along a first direction. The connecting portion 422 is disposed at both ends of the second main body plate 421 along a second direction. The connecting portion 422 is provided with a snap-fit ​​portion 4221, and the side plate 41 is provided with a slot 4111. The snap-fit ​​portion 4221 and the slot 4111 are inserted into each other to realize a detachable connection between the first connector 42 and the side plate 41, so as to improve the assembly efficiency of the connector 42 and the side plate 41. Of course, in other embodiments, the slot 4111 can be disposed on the connecting portion 422, and the snap-fit ​​portion 4221 can be disposed on the side plate 41, which can achieve the same effect.

[0064] Optionally, the snap-fit ​​part 4221 is provided with a guide slope 42211, so that the entire snap-fit ​​part 4221 is formed into a wedge-shaped structure. The snap-fit ​​part 4221 can be snapped into the slot 4111 along the guide slope 42211, so that the snap-fit ​​part 4221 can slide into the slot 4111 better, so as to facilitate the quick assembly of the snap-fit ​​part 4221 and the slot 4111.

[0065] Optionally, the second main body plate 421 is provided with a tab hole 4211. The positive tab of the electrode group 30 passes through the tab hole 4211 of one of the second main body plates 421 and is connected to one of the end caps 20. The negative tab passes through the tab hole 4211 of the other second main body plate 421 and is connected to the other end cap 20. The tab hole 4211 realizes the avoidance function of the positive tab and the negative tab of the electrode group 30.

[0066] Optionally, the connector 42 further includes a plurality of second protrusions 423, which are disposed on the outer side of the second main body plate 421. In this embodiment, the second main body plate 421 is elongated, the second protrusions 423 extend along the width direction of the second main body plate 421, and the plurality of second protrusions 423 are spaced apart along the length direction of the second main body plate 421. On the one hand, this can improve the overall strength of the second main body plate 421; on the other hand, it can form a gap between the second main body plate 421 and the end cap 20, which facilitates venting and thus improves the safety of the battery 100.

[0067] Optionally, the side plate 41 includes a first main plate 411 and a first protrusion 412. The first main plate 411 abuts against the side of the electrode assembly 30 along the second direction. The first protrusion 412 is disposed on the outer side of the first main plate 411 and abuts against the inner wall of the housing 10. By providing the first protrusion 412, a gap can be formed between the first main plate 411 and the housing 10. This gap is conducive to venting and further improves the safety performance of the battery 100.

[0068] Optionally, there are two first protrusions 412, which are arranged at intervals along a third direction. At least a portion of the connector 42 (specifically the connecting portion 422) is located between the two first protrusions 412. When the connector 42 and the side plate 41 are assembled, the first protrusions 412 can provide guidance for the connecting portion 422 to avoid the connecting portion 422 from being misaligned when it is assembled with the side plate 41, thereby further improving the assembly efficiency of the connector 42 and the side plate 41.

[0069] like Figure 7 and Figure 8As shown, the side plate 41 (specifically the first main plate 411) is provided with a plug-in part 413, and the top plate 44 is provided with a plug-in groove 442 that is adapted to the plug-in part 413. The plug-in part 413 can be plugged into the plug-in groove 442 to facilitate the rapid assembly of the top plate 44 and the side plate 41, thereby improving the assembly efficiency of the battery 100.

[0070] Optionally, the width of the insertion groove 442 gradually increases from the opening to the bottom of the groove to improve the connection strength between the top plate 44 and the first main body plate 411 and prevent the top plate 44 from detaching from the first main body plate 411.

[0071] Optionally, the insertion part 413 is the same length as the first main body plate 411 to increase the connection size between the top plate 44 and the first main body plate 411, further improve the connection strength between the top plate 44 and the first main body plate 411, and further prevent the top plate 44 from detaching from the first main body plate 411.

[0072] Optionally, the bottom plate 43 is provided with a plurality of first through holes 431, and / or the top plate 44 is provided with a plurality of second through holes 441, so as to facilitate the flow and wetting of electrolyte.

[0073] Optionally, a plurality of first through holes 431 are arranged in an array, and a plurality of second through holes 441 are arranged in an array, so that the electrolyte can flow and wet uniformly.

[0074] Optionally, the thickness of the top plate 44 is T1, which is greater than or equal to 0.5 mm and less than or equal to 1.5 mm. This is to prevent structural deficiencies due to insufficient thickness of the top plate 44, while also preventing excessive thickness of the top plate 44 from occupying too much space inside the housing 10. For example, the value of T1 can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, or 1.5 mm. Of course, in other embodiments, the value of T1 is not limited to these values, and designers can make adaptive adjustments according to actual needs.

[0075] Optionally, the thickness of the base plate 43 is T2, which is greater than or equal to 0.4 mm and less than or equal to 1.5 mm. This is to prevent structural deficiencies due to insufficient thickness of the base plate 43, while also preventing excessive thickness of the base plate 43 from occupying too much space inside the housing 10. For example, the value of T2 can be 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, or 1.5 mm. Of course, in other embodiments, the value of T2 is not limited to these values, and designers can make adaptive adjustments according to actual needs.

[0076] 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.

[0077] 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.

[0078] like Figure 3 and Figure 9 As shown, the battery 100 also includes a spacer 50, which includes a first spacer portion 51 and a second spacer portion 52 arranged in a cross manner. The first spacer portion 51 is disposed between the electrode components 31 arranged along the second direction, and the second spacer portion 52 is disposed between the electrode components 31 arranged along the first direction. The first spacer portion 51 and the second spacer portion 52 separate the electrode components 31, thereby preventing friction or collision between adjacent electrode components 31 during use, thus avoiding damage or short circuit of the electrode components 31 and improving the safety and service life of the battery 100.

[0079] The second spacer 52 has a through hole 521. The tabs of two adjacent polar component parts 31 arranged along the first direction pass through the through hole 521 and are connected to each other. The through hole 521 is provided to enable the second spacer 52 to avoid the tabs of the polar component parts 31.

[0080] Optionally, the spacer 50 also includes a protective part 53, which is formed by the second spacer 52 extending from one end in the third direction towards the length of the pole group 30. The protective part 53 abuts against the pole group 31, thereby supporting and fixing the pole group 31 and improving the overall vibration resistance of the pole group 30.

[0081] Optionally, the first spacer 51, the second spacer 52, and the protective part 53 are integrally formed to reduce the number of parts, simplify the assembly process, and make installation simple.

[0082] Optionally, the spacer 50 is produced by injection molding, which has high production efficiency and good product quality.

[0083] like Figure 1 , Figure 10 and Figure 11As 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 40 (specifically the second main body plate 421). 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 second main body plate 421 to facilitate exhaust, thereby improving the safety of the battery 100.

[0084] In addition, after the end cap 20 is assembled with the housing 10, the support protrusion 22 abuts against the second main body plate 421, eliminating the need for a separate lower plastic, simplifying the assembly process and improving the space utilization of the battery 100.

[0085] 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.

[0086] In this embodiment, a third explosion-proof hole 211 is provided on the cover plate 21, and a first explosion-proof hole 11 and a second explosion-proof hole 12 are provided on the housing 10. Explosion-proof valves are provided in the first explosion-proof hole 11, the second explosion-proof hole 12 and the third explosion-proof hole 211. 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, and the explosion-proof valve opens. Gas is discharged from the first explosion-proof hole 11, the second explosion-proof hole 12 and the third 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.

[0087] Two first explosion-proof holes 11 are provided on one side of the housing 10 along the second direction, and the two first explosion-proof holes 11 are arranged at intervals along the first direction. A second explosion-proof hole 12 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 explosion-proof holes 11 and the second explosion-proof holes 12 can be adaptively adjusted according to actual needs.
