[0051] Example 1
[0052] 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.
[0053] In this embodiment, the housing 10 has openings at both ends along the first direction. The battery 100 also includes two end caps 20, each end cap 20 comprising a cover plate 21. The two cover plates 21 are respectively placed over the corresponding openings. The electrode assembly 30 is connected to the cover plate 21, and the cover plate 21 is 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.
[0054] In existing technologies, the electrode assembly is easily damaged by collision with the casing during installation, which reduces the yield rate of the battery. In addition, the electrode tabs are welded to the cover plate, which is a complicated process and affects the production efficiency of the battery.
[0055] To solve the above problems, such as Figures 1-3 As shown, the battery 100 provided in this embodiment also includes a support frame 50, which surrounds the outer periphery of the electrode group 30 and is disposed inside the housing 10. The support frame 50 has electrode tab holes 511 at both ends along the first direction and an end cap 20, which includes a cover plate 21 and a conductive element 23. The end cap 20 covers the opening of the housing 10, and the conductive element 23 is disposed inside the cover plate 21 and abuts against the support frame 50. The conductive element 23 has a clamping groove 2321. The electrode group 30 has electrode tabs at both ends along the first direction, which pass through the corresponding electrode tab holes 511 and are embedded in the clamping groove 2321.
[0056] The battery 100 provided in this embodiment, through the support frame 50 surrounding the electrode assembly 30, can prevent the electrode assembly 30 from directly contacting the housing 10 when the electrode assembly 30 is inserted into the housing, thereby avoiding damage to the electrode assembly 30 during insertion. By embedding the electrode tabs of the electrode assembly 30 in the clamping groove 2321, there is no need to weld the electrode assembly 30 to the cover plate 21, saving welding steps, avoiding the welding heat-affected zone, and improving the production efficiency of the battery 100. The electrode tabs are clamped in the clamping groove 2321 in a non-fixed connection, supporting non-destructive disassembly, facilitating the replacement or cascade utilization of the electrode assembly 30, reducing maintenance costs, and reducing the total life cycle cost of the battery 100.
[0057] Optionally, the conductive component 23 includes a main body 231 and a clamping part 232. The cover plate 21 has a receiving groove 211. The main body 231 is disposed in the receiving groove 211. The clamping part 232 is erected on the main body 231 and abuts against the support frame 50. The clamping groove 2321 is disposed on the clamping part 232, so that the size of the clamping groove 2321 is not limited by the size of the main body 231. The size of the clamping part 232 can be customized according to the tab specifications to ensure that the tab is fully embedded and does not wobble, and to avoid positional displacement during free clamping.
[0058] Optionally, the length of the main body 231 is L1, meaning the dimension of the main body 231 in the second direction is L1, where L1 is greater than or equal to 40mm and less than or equal to 80mm. Optionally, the width of the main body 231 is W1, meaning the dimension of the main body 231 in the third direction is W1, where W1 is greater than or equal to 10mm and less than or equal to 25mm. Optionally, the thickness of the main body 231 is T1, meaning the dimension of the main body 231 in the first direction is T1, where T1 is greater than or equal to 0.7mm and less than or equal to 1.6mm. These dimensional settings ensure a good connection between the tab and the main body 231.
[0059] For example, the length L1 of the main body 231 can be 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, or 80mm. The width W1 of the main body 231 can be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, or 25mm. The thickness T1 of the main body 231 can be 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, or 1.6mm. Of course, in other embodiments, the values of L1, W1, and T1 are not limited to the above ranges, and designers can adjust them adaptively according to actual needs.
[0060] Optionally, the length of the clamping part 232 is L2, meaning the dimension of the clamping part 232 in the second direction is L2, which is greater than or equal to 25mm and less than or equal to 80mm. Optionally, the width of the clamping part 232 is W2, meaning the dimension of the clamping part 232 in the first direction is W2, which is greater than or equal to 6mm and less than or equal to 15mm. Optionally, the width of the clamping part 232 is T2, meaning the dimension of the clamping part 232 in the third direction is T2, which is greater than or equal to 2mm and less than or equal to 4mm. These dimensional settings ensure that the tab can be well embedded within the clamping groove 2321.
[0061] For example, the length L2 of the clamping portion 232 can be 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, or 80mm. The width W2 of the clamping portion 232 can be 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, or 15mm. The thickness T2 of the clamping portion 232 can be 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm, or 4mm. Of course, in other embodiments, the values of L2, W2 and T2 are not limited to the above ranges, and designers can make adaptive adjustments according to actual needs.
[0062] Optionally, the tabs and the corresponding conductive parts 23 are made of the same material. Specifically, the tabs of the electrode group 30 include a positive tab and a negative tab. When the positive tab is made of aluminum, the conductive parts 23 connected to the positive tab are also made of aluminum; when the negative tab is made of copper, the conductive parts 23 connected to the negative tab are also made of copper.
[0063] Optionally, the battery 100 also includes a support frame 50, and the end cover 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, thereby improving the safety of the battery 100 in use.
[0064] To avoid deformation or other problems caused by excessive size of the electrode assembly 30, the electrode assembly 30 includes two electrode assembly components 31 arranged along the first direction, and the two electrode assembly components 31 are connected in series. In other embodiments, the number of electrode assembly components 31 may also be three, four or more.
[0065] 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.
[0066] like Figure 1 and Figure 4As shown, the support frame 50 includes two first side plates 51 arranged along a first direction and two second side plates 52 arranged along a second direction. The first side plates 51 and the second side plates 52 are connected end to end to form a receiving cavity. The electrode assembly 30 is disposed in the receiving cavity. The support frame 50 is disposed in the housing 10. The first side plates 51 and the second side plates 52 provide support and protection for the sides of the electrode assembly 30, thereby improving the structural strength of the battery 100. In addition, when the electrode assembly 30 is inserted into the housing, the support frame 50 can prevent the electrode assembly 30 from directly contacting the housing 10, thereby avoiding damage to the electrode assembly 30 when it is inserted into the housing.
[0067] 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 and the second direction may be set at other angles, which are not limited here. In another optional embodiment, the first direction may be the length direction of the battery 100, and the second direction may be the width direction of the battery 100.
[0068] Optionally, the second side plate 52 is provided with a plurality of second through holes 521, which are arranged at intervals along the first direction to facilitate venting and improve the safety performance of the battery 100.
[0069] Optionally, the first side plate 51 is provided with a plurality of tab holes 511 arranged at intervals along the second direction. The tabs of the electrode component 31 pass through the corresponding tab holes 511 and are connected to the conductive component 23. The tab holes 511 realize the avoidance function of the first side plate 51 on the tabs.
[0070] Optionally, the first side plate 51 and the second side plate 52 are integrally formed, which saves the connection structure between the first side plate 51 and the second side plate 52, thereby reducing the number of parts, simplifying the assembly process, and making installation simple, while also helping to improve the overall strength of the support frame 50.
[0071] Optionally, the support frame 50 also includes an extension plate 53, which is formed by the second side plate 52 extending into the receiving cavity along one side edge in the third direction. The extension plate 53 abuts against one side of the pole group 30 in the third direction to improve the support and protection effect of the support frame 50 on the pole group 30.
[0072] Optionally, the support frame 50 is made of insulating material to achieve insulation between the electrode assembly 30 and the inner wall of the housing 10, thereby improving the safety performance of the battery 100.
[0073] Optionally, the support frame 50 is made by injection molding, which has high production efficiency and good product quality.
[0074] like Figure 1 and Figure 5 As shown, the battery 100 also includes a spacer mechanism 60, which is sandwiched between two adjacent electrode components 31 to prevent short circuits or structural deficiencies between the two adjacent electrode components 31.
[0075] Optionally, a first slot 512 is provided on the first side plate 51. The first slot 512 extends along a third direction, and the two ends of the spacer mechanism 60 along the first direction are respectively inserted into the corresponding first slot 512 to facilitate the quick assembly of the spacer mechanism 60 and the first side plate 51.
[0076] Optionally, the spacer mechanism 60 includes two spacers 61 arranged along the first direction. By dividing the spacer mechanism 60 into two separate spacers 61, the length of a single spacer 61 can be shortened, reducing the molding difficulty of the spacers 61.
[0077] Specifically, the spacer 61 includes a connecting portion 611 and a supporting portion 612. The connecting portion 611 is sandwiched between two adjacent electrode component parts 31. The supporting portion 612 is formed by at least a portion of the connecting portion 611 extending along a second direction. The supporting portion 612 is provided with a through groove 6121. The tabs of the two adjacent electrode component parts 31 are connected and are all disposed in the through groove 6121 to protect one side of the tab along a third direction and avoid damage to the connection point of the tabs of the two adjacent electrode component parts 31.
[0078] Optionally, two adjacent electrode components 31 are provided with grooves on the side close to each other, and the support portion 612 is located in the corresponding grooves on both sides along the second direction, so as to make full use of the space of the receiving cavity and increase the capacity of the battery 100.
[0079] Optionally, the support portion 612 is provided with a cavity 6122 with an open end, which helps to reduce the weight of the support portion 612 and thus facilitates the lightweight design of the battery 100.
[0080] Optionally, the spacer 61 also includes a plug 613, which covers the opening of the cavity 6122 of the support 612 to protect the tabs from damage to the tab connection between adjacent two electrode components 31.
[0081] In this embodiment, the plug 613 has multiple first through holes 6131 to facilitate the flow of venting and electrolyte. Optionally, the multiple first through holes 6131 are arranged in an array to improve the uniformity of venting and electrolyte flow.
[0082] Optionally, the spacer 61 further includes a fixing part 614, which is formed by at least a portion of the connecting part 611 extending along a second direction along one side of a third direction. The fixing part 614 abuts against the side of the electrode component 31 along the third direction to improve the fixing and supporting effect of the spacer 61 on the electrode component 31, thereby improving the structural strength of the battery 100.
[0083] like Figure 1 As shown, the housing 10 has two first explosion-proof holes 11 on one side along a third direction, and a second explosion-proof hole 212 on the cover plate 21. The two first explosion-proof holes 11 are arranged at intervals along a first direction. Each of the first explosion-proof holes 11 and the second explosion-proof hole 212 is equipped with an explosion-proof valve. 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 then opens, and gas is discharged from the first explosion-proof hole 11 and the second explosion-proof hole 212, releasing the internal pressure of the housing 10 and preventing thermal runaway and explosion / fire of the battery 100, thus improving the safety of the battery 100. In other embodiments, the number and location of the first explosion-proof holes 11 can be adjusted according to actual needs.
[0084] 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 covered with the insulating film 40 is 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.
[0085] 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.
[0086] Optionally, the insulating film 40 is provided with slits, and the first explosion-proof hole 11 is directly opposite to the slits and is provided in a one-to-one correspondence, so that the gas in the electrode group 30 can be quickly discharged through the slits.
