As shown in fig. 3 to 5, the embodiment of the present application provides a battery 2, where the battery 2 includes a battery 2 main body 20 and a gate line structure disposed on at least one side of the battery 2 main body 20, the gate line structure includes a plurality of first gate lines 21 extending along a first direction and a plurality of bonding pads 22, and each bonding pad 22 is formed of at least one second gate line 221.
Based on this, as shown in fig. 3 to 5, in the battery 2 provided in the embodiment of the present application, the grid line structure disposed on at least one surface of the main body 20 of the battery 2 includes a plurality of first grid lines 21 and a plurality of bonding pads 22, that is, the battery 2 provided in the embodiment of the present application is a non-main grid battery, and compared with the current multi-main grid battery 2, the battery 2 provided in the embodiment of the present application greatly reduces the usage amount of silver paste by removing the main grid on at least one surface of the main body 20 of the battery 2, thereby reducing the production cost of the battery 2. Meanwhile, the battery 2 provided by the embodiment of the application is provided with the plurality of bonding pads 22 on at least one surface of the main body 20 of the battery 2, and the bonding pads 22 are connected with the welding strip 3, so that the electric connection between the welding strip 3 and the battery 2 is realized, the contact area between the welding strip 3 and the battery 2 is increased, and the welding tension and the connecting effect between the battery 2 and the welding strip 3 are further enhanced. Each bonding pad 22 is formed by at least one second gate line 221, and compared with the solid welding spot in the current battery without main gate, the battery 2 provided in the embodiment of the present application reduces the projection area of the bonding pad 22 on the main body 20 of the battery 2, so that the silver paste consumption at the bonding pad 22 is reduced, which is beneficial to further reducing the production cost of the battery 2. In addition, when the grid line structure provided in the embodiment of the present application is located on the light-facing surface of the main body 20 of the battery 2, the light-shielding degree of the light-facing surface of the battery 2 can be reduced, which is beneficial to improving the battery efficiency of the battery 2.
In some examples, the gate line structure provided in the embodiments of the present application may be located on one side of the battery body 20, or may be located on two opposite sides of the battery body 20, which is not limited in the embodiments of the present application.
In some examples, the pad 22 may include only one second gate line 221, as shown in fig. 3
The connection effect between the battery 2 and the solder strip 3 is further enhanced by including a plurality of second gate lines 221 as shown in fig. 4.
As a possible implementation manner, as shown in fig. 3 to 5, when the pad 22 is formed of a plurality of second gate lines 221, in the same pad 22, the extending directions of the second gate lines 221 are all the same; or alternatively, the first and second heat exchangers may be,
the second gate line 221 has at least two different extending directions within the same pad 22.
Based on this, as shown in fig. 3 to 5, in the battery 2 provided in the embodiment of the present application, all the second gate lines 221 forming the bonding pads 22 may have the same extending direction, be regularly arranged on the surface of the main body 20 of the battery 2, or may have at least two different extending directions, and the second gate lines 221 at this time are connected to each other by being staggered on the surface of the main body 20 of the battery 2. The extending direction of the second gate line 221 in the bonding pad 22 is not specifically limited, and may be specifically selected according to practical situations, but no matter whether the extending direction of the second gate line 221 is the same or different, the second gate line 221 plays a role in realizing the electrical connection between the battery 2 and the bonding pad 3.
As shown in fig. 3 to 5, when the pad 22 is formed of 6 second gate lines 221, the extending directions of each of the second gate lines 221 are different in the same pad 22, which is only an example and not particularly limited.
As shown in fig. 5, in addition to the electrical connection with the solder ribbon 3 using the pad 22 constituted by the second gate line 221, in the connection between the solder ribbon 3 and the battery 2, the embodiment of the present application also fixes the solder ribbon 3 by the glue dot 4 so that the solder ribbon 3 is alloyed with the first gate line 21 in the laminator so that carriers collected by the first gate line 21 can be transferred to the solder ribbon 3.
As a possible implementation manner, as shown in fig. 3 to 5, the first gate lines 21 are uniformly spaced along the second direction, and each pad 22 connects two adjacent first gate lines 21, and the second direction is perpendicular to the first direction.
Based on this, as shown in fig. 3 to 5, in the battery 2 provided in the embodiment of the present application, the first grid lines 21 located on the surface of the main body 20 of the battery 2 extend along the first direction, are uniformly distributed at intervals along the second direction, and the first direction is perpendicular to the second direction, so that the photo-generated current generated by the main body 20 of the battery 2 can be collected and transmitted to the solder strip 3, and finally led out by the bus bar. Each bonding pad 22 is connected with two adjacent first grid lines 21, namely, the two adjacent first grid lines 21 are connected through the bonding pad 22, so that breakage of the two adjacent first grid lines 21 can be reduced, stability is guaranteed, and the first grid lines 21 can still collect carriers to be transferred to the welding strip 3 under the condition of partial breakage, so that battery efficiency of the battery 2 is further improved.
In some examples, as shown in fig. 3 to 5, each second gate line 221 connects two adjacent first gate lines 21, and at least one connection point is provided between the second gate line 221 and each adjacent first gate line 21.
Based on this, as shown in fig. 3 to 5, the two first gate lines 21 adjacent to the bonding pad 22 are connected with the second gate lines 221 included in the bonding pad 22, so that the connection of the two adjacent first gate lines 21 is realized, that is, the bonding pad 22 formed by the second gate lines 221 not only can realize the electric connection between the battery 2 and the bonding pad 3, but also is equivalent to a breaking-preventing gate structure, thereby not only reducing breaking gates, ensuring stability, but also being beneficial to ensuring the collection of carriers after the first gate lines 21 adjacent to the bonding pad 22 break, and improving the battery efficiency of the battery 2. In order to play a role of preventing gate breakage, at least one connection point should be provided between the second gate line 221 and each adjacent first gate line 21, and as the number of connection points increases, the gate breakage preventing effect of the second gate line 221 is enhanced, but the consumption of silver paste is correspondingly increased, and in actual production, the number of connection points between the second gate line 221 and the adjacent first gate line 21 may be specifically selected according to the consumption of silver paste and the gate breakage preventing effect, which is not limited herein.
As shown in fig. 3 to 5, there may be three connection points between the second gate line 221 and each adjacent first gate line 21, which is only exemplary and not particularly limited.
As one possible implementation, as shown in fig. 3-5, the pads 22 have a first length L in the first direction, 0 < l.ltoreq.1.5 mm. Based on this, in the first direction, the bonding pads 22 between the first gate lines 21 have a first length L, and 0 < L is less than or equal to 1.5mm, that is, the overall size of the bonding pads 22 in the first direction should be less than or equal to 1.5mm, and if the size of the bonding pads 22 in the first direction is greater than 1.5mm, the size of the bonding pads 22 is too large, the density of the second gate lines 221 forming the bonding pads 22 is too small, so that the electrical connection effect between the second gate lines 221 and the solder strips 3 cannot be ensured, and the silver paste consumption increases accordingly, which is disadvantageous for reducing the production cost.
By way of example, the bonding pad 22 may have a first length L in the first direction of 0.2mm, 0.5mm, 0.7mm, 1mm, 1.2mm, 1.5mm, etc., by way of example only and not limitation.
As one possible implementation, as shown in fig. 3 to 5, the pads 22 are uniformly distributed on the battery 2 main body 20 in the form of mxn, wherein in the second direction, the number of pads 22 is M, in the first direction, the number of pads 22 is N, M is an integer of 3 or more and 7 or less, and N is an integer of 5 or more and 20 or less.
Based on this, as shown in fig. 3 to 5, in the battery 2 provided in the embodiment of the present application, the bonding pads 22 are uniformly distributed on the main body 20 of the battery 2 in the form of mxn, and considering that the shape of the bonding strap 3 is mostly elongated extending along a single direction, the bonding pads 22 uniformly distributed in the form of mxn are beneficial to the regular arrangement of the bonding strap 3 on the surface of the battery 2, so that the connection effect between the bonding pads 22 and the bonding strap 3 is ensured, and further the connection effect between the battery 2 and the bonding strap 3 is ensured. The number of the bonding pads 22 is M along the second direction, the number of the bonding pads 22 is N along the first direction, M is an integer greater than or equal to 3 and less than or equal to 7, N is an integer greater than or equal to 5 and less than or equal to 20, if the number of the bonding pads 22 in the second direction is less than 3 or the number of the bonding pads 22 in the first direction is less than 5, the connection effect of the bonding strap 3 and the battery 2 is close to that of a battery without a main grid, and the effect of enhancing the electrical connection cannot be achieved; if the number of the bonding pads 22 in the second direction is greater than 7 or the number of the bonding pads 22 in the first direction is greater than 20, the number of the bonding pads 22 is too large, and the consumption of silver paste is too large, which is disadvantageous in reducing the production cost.
For example, the number of pads may be 3, 4, 5, 6, 7, etc. in the second direction, and the number of pads may be 5, 9, 11, 15, 17, 20, etc. in the first direction, by way of example only, and not limitation.
In some examples, as shown in fig. 3 to 5, when the pads 22 are uniformly distributed in the form of mxn on the battery 2 main body, there is a first spacing d between two adjacent pads 22 in the second direction 1 ，10mm≤d 1 Less than or equal to 36mm; with a second spacing d between two adjacent pads 22 in the first direction 2 ，5mm≤d 2 ≤40mm。
Based on this, as shown in fig. 3 to 5, in the battery 2 provided in the embodiment of the present application, when the pads 22 are uniformly distributed in the form of mxn on the battery 2 main body, the pads 22 have the first pitch d in the second direction 1 D is more than or equal to 10mm 1 Less than or equal to 36mm, and has a second distance d in the first direction 2 D is not less than 5mm 2 Less than or equal to 40mm, if the first spacing d of the bonding pads 22 in the second direction 1 A second distance d of less than 10mm or in the first direction 2 The number of the bonding pads 22 is less than 5mm, the connection effect of the bonding tape 3 and the battery 2 is close to that of the battery 2 without the main grid, which is formed by removing only the main grid, and the effect of enhancing the electric connection cannot be achieved; if the first spacing d of the bonding pads 22 in the second direction 1 A second distance d of greater than 36mm or in the first direction 2 And more than 40mm, the number of the bonding pads 22 is too large, and the consumption of silver paste is too large, so that the production cost is not reduced.
Exemplary, when the pads are uniformly distributed in the form of M N on the battery body, a first spacing d between two adjacent pads in the second direction 1 May be 10mm, 15mm, 20mm, 25mm, 30mm, 36mm, etc., a second spacing d between adjacent two pads in the first direction 2 May be 5mm, 10mm, 20mm, 25mm, 30mm, 35mm, 40mm, etc., by way of example only, and is not particularly limited.
As a possible implementation, as shown in fig. 3 to 5, the pads 22 have an axisymmetric structure along the second direction. Based on this, when the bonding pad 22 is in an axisymmetric structure symmetric about the second direction, the bonding strap 3 contacts the bonding pad 22 in the same structure on both sides perpendicular to the second direction, so that the non-uniformity of the tensile force is avoided, the contact effect between the bonding strap 3 and the bonding pad 22 is ensured, and the welding tensile force and the connection effect between the battery 2 and the bonding strap 3 are further enhanced.
As a possible implementation manner, as shown in fig. 3 to 5, a third distance d is provided between two adjacent first gate lines 21 along the second direction 3 ，1mm≤d 3 ≤1.8mm。
Based on this, as shown in fig. 3 to 5, in the battery 2 provided in the embodiment of the present application, the first grid lines 21 uniformly spaced apart along the second direction have the third spacing d therebetween 3 D is not less than 1mm 3 Less than or equal to 1.8mm, if the third spacing d 3 If the distance between the first grid lines 21 is smaller than 1mm, the number of the bonding pads 22 is correspondingly increased, which is not beneficial to saving silver paste and increases the production cost of the battery 2; if the third distance d 3 If the distance between the first grid lines 21 is larger than 1.8mm, the distance is too wide, which is not only unfavorable for collecting carriers, but also too few contact points between the solder strip 3 and the first grid lines 21, so that the battery efficiency of the battery 2 cannot be ensured.
Exemplary, in the second direction, a third spacing d is provided between two adjacent first gate lines 3 May be 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, etc., by way of example only, and is not particularly limited.
