Detailed Description
The invention will be described in detail with reference to the following drawings, which are provided for illustration purposes and the like:
referring to fig. 1, fig. 2 and fig. 3, a top view and a cross-sectional view of an embodiment of a battery conductive frame according to the invention are respectively shown. As shown in the figure, the battery conductive frame 10 mainly includes a first conductive portion 11 and a plurality of second conductive portions 13, wherein the first conductive portion 11 includes a plurality of connection holes 12, the second conductive portions 13 are disposed in the connection holes 12 of the first conductive portion 11, and the first conductive portion 11 and the second conductive portions 13 are made of different materials.
The first conductive portion 11 includes a first surface 111 and a second surface 113, wherein the first surface 111 and the second surface 113 may be two opposite surfaces of the first conductive portion 11, and the connection hole 12 is disposed on the first surface 111 and/or the second surface 113 of the first conductive portion 11, for example, the first surface 111 is a lower surface, and the second surface 113 is an upper surface.
The second conductive portion 13 can be inserted into the connection hole 12, wherein a portion of the second conductive portion 13 is located inside the connection hole 12, and a portion of the second conductive portion 13 is located outside the connection hole 12, and a protrusion 131 is formed on a surface (e.g., the first surface 111) of the first conductive portion 11. The battery conductive frame 10 can be connected to a battery cell 15 through the protrusion 131, for example, connected to a housing 151 of the battery cell 15, wherein the housing 151 is made of metal.
In practical applications, the battery holder 10 and the battery core 15 may be connected by welding (welding) or resistance welding, as shown in fig. 4, the protruding portion 131 on the second surface 113 of the first conductive portion 11 may contact the housing 151 of the battery core 15, and the power is supplied to the second conductive portion 13 through a power supply electrode 19, so that the current is transmitted to the housing 151 of the battery core 15 through the protruding portion 131 of the second conductive portion 13, the temperature of the protruding portion 131 of the second conductive portion 13 and the housing 151 of the battery core 15 in contact is increased, and the eutectic portion 17 is formed between the battery holder 10, the first conductive portion 11, and/or the second conductive portion 13 and the battery core 15.
During the resistance welding process, the battery conductive frame 10 may also be pressed toward the battery cell 15 by the power feeding electrode 19 to facilitate the connection between the battery conductive frame 10 and the battery cell 15. Specifically, when current passes through protruding portion 131 of second conductive portion 13 and case 151 of battery cell 15, protruding portion 131 of second conductive portion 13 and case 151 of battery cell 15 in contact therewith soften due to temperature rise, and when the temperature of protruding portion 131 of second conductive portion 13 and case 151 of battery cell 15 reaches a specific value, they melt to form a molten pool. The softened protrusion 131 can be pressed by the power supply electrode 19 through the first conductive part 11 to facilitate forming the eutectic part 17 between the battery frame 10 and/or the first conductive part 11 and the battery core 15, and completing the connection between the battery frame 10 and the battery core 15.
Generally, the battery frame is usually made of a material with low resistance and high conductivity, so as to reduce energy loss caused by charging and discharging the battery core through the battery frame. However, when the low-resistance battery conductive frame and the shell of the battery core are connected by resistance welding, it is necessary to supply a large current to the battery conductive frame and the shell of the battery core, and the energy consumed for welding the battery conductive frame and the battery core is increased.
In addition, the battery frame usually has a larger thickness to increase the sectional area of the battery frame and reduce the resistance of the battery frame. However, as the thickness of the battery conductive frame is increased, the structural strength of the battery conductive frame is improved, so that the battery conductive frame is less prone to deformation when the battery conductive frame is connected with the shell of the battery core. Therefore, when pressure is applied to the shell of the battery cell through the battery conductive frame, the shell of the battery cell is greatly deformed, for example, the protruding welding parts on the battery conductive frame form deeper or wider depressions on the shell of the battery cell.
Therefore, in the process of connecting the battery conductive frame and the battery core, the casing structure of the battery core may be damaged, for example, metal cracks may be generated on the casing of the battery core, thereby affecting the reliability and durability of the battery core. However, if a battery lead frame with high resistance and low conductivity is selected to avoid the above-mentioned problems occurring when welding the battery lead frame and the battery cell, energy loss caused when the battery cell is charged and discharged through the battery lead frame is increased.
In order to solve the above problems, the present invention proposes to manufacture the battery conductive frame 10 by two different materials, wherein the first conductive part 11 and the second conductive part 13 are made of different materials, respectively, and the resistance and/or resistivity of the second conductive part 13 is greater than that of the first conductive part 11, i.e. the conductivity of the first conductive part 11 is higher than that of the second conductive part 13. For example, first conductive portion 11 may be copper and second conductive portion 13 may be nickel.
Since second conductive portion 13 has a large resistance, when second conductive portion 13 of battery holder 10 and case 151 of battery cell 15 in contact are connected by resistance welding, the current supplied to second conductive portion 13 can be reduced, and second conductive portion 13 and case 151 of battery cell 15 can be connected by resistance welding, thereby effectively reducing the energy consumed in connecting battery conductive portion 10 and battery cell 15.
In addition, since protruding portion 131 of second conductive portion 13 protruding from the surface of first conductive portion 11 has poor structural strength, when second conductive portion 13 and case 151 of battery cell 15 are connected by resistance welding, second conductive portion 13 and case 151 of battery cell 15 are deformed, so that the degree of deformation of case 151 of battery cell 15 can be reduced, for example, protruding portion 131 of the surface of first conductive portion 11 is deformed during resistance welding, and the depth and/or area of the deformed portion generated by pressing case 151 of battery cell 15 by protruding portion 131 can be reduced. Therefore, the structure of the case 151 of the battery cell 15 can be prevented from being damaged in the process of connecting the battery conductive frame 10 and the battery cell 15, for example, the case 151 of the battery cell 15 can be prevented from generating metal cracks, so as to improve the durability and reliability of the battery cell 15.
Since the resistance of the first conductive part 11 is low, the resistance of the battery frame 10 is not greatly increased by the second conductive part 13, and the energy loss caused by charging and discharging the battery core 15 through the battery frame 10 can be reduced.
In an embodiment of the present invention, as shown in fig. 1, the first conductive part 11 has a fishbone-like appearance and has a plurality of branches 115, for example, the first conductive part 11 may include six branches 115, wherein each branch 115 is connected to one battery cell 15, so that the battery conductive frame 10 is connected to six battery cells 15 in series and/or in parallel.
In another embodiment of the present invention, each branch 115 of the first conductive part 11 may include a plurality of sub-branches 117, and a gap 112 is formed between adjacent sub-branches 117, wherein the plurality of sub-branches 117 of the same branch 115 are used to connect the same battery cell 15. Furthermore, each sub-branch 117 may be provided with at least one connection hole 12, and the second conductive part 13 may be disposed in the connection hole 12 of each sub-branch 117. For example, the first conductive part 11 may comprise six branches 115, wherein each branch 115 comprises two sub-branches 117, and each branch 115 connects the same battery cell 15 via two second conductive parts 13. Specifically, the number of branches 115 and sub-branches 117 on first conductive portion 11 and the number of second conductive portions 13 and battery cells 15 are not limitations of the scope of the present invention.
Each branch 115 of the first conductive part 11 is provided with two or more sub-branches 117, and each sub-branch 117 is provided with at least one second conductive part 13. As shown in fig. 4, the feeding electrode 19 includes a first electrode 191 and a second electrode 193, wherein the first electrode 191 and the second electrode 193 are respectively connected to the second conductive part 13 of the different sub-branches 117 on one branch 115 of the first conductive part 11, and the first electrode 191 supplies current to the second conductive part 13 on the connected sub-branch 117.
Because of the gap between the sub-branches 117, most of the current is transmitted from the second conductive part 13 on the sub-branch 117 connected to the first electrode 191 to the housing 151 of the battery cell 15, and then transmitted back to the second electrode 193 through the second conductive part 13 on the sub-branch 117 connected to the second electrode 193, thereby increasing the current flowing through the second conductive part 13 and the housing 151 of the battery cell 15 in contact, and facilitating to increase the temperature of the second conductive part 13 and the housing 151 of the battery cell 15 in contact.
In an embodiment of the present invention, the connection hole 12 may penetrate through the first conductive portion 11 and connect the first surface 111 and the second surface 113 of the first conductive portion 11, and the second conductive portion 13 disposed in the connection hole 12 extends from the first surface 111 to the second surface 113 of the first conductive portion 11, wherein the second conductive portion 13 forms the protrusion 131 on the first surface 111 of the first conductive portion 11.
In another embodiment of the present invention, an inner surface of the connection hole 12 may be provided with an inner thread, and the second conductive portion 13 has a substantially cylindrical appearance, and an outer surface of the second conductive portion 13 is provided with an outer thread, such as the connection hole 12 of the first conductive portion 11 similar to a screw hole and the second conductive portion 13 similar to a screw, so that the second conductive portion 13 can be locked on the connection hole 12 via the inner and outer threads.
As shown in fig. 2 and fig. 3, the second conductive portion 13 includes a first end 132 and a second end 134, and when the second conductive portion 13 is disposed in the connection hole 12 of the first conductive portion 11, the first end 132 of the second conductive portion 13 will protrude from the first surface 111 of the first conductive portion 11 to form a protruding portion 131. In addition, the second end 134 of the second conductive portion 13 may be provided with a head portion 135, wherein the cross-sectional area of the head portion 135 is larger than that of the connection hole 12.
In another embodiment of the present invention, as shown in fig. 5, the second conductive portion 23 may have a cylindrical shape and a uniform cross-sectional area, such as a cylinder. In other words, the second conductive portion 23 of the present embodiment does not have the header 135 of the second conductive portion 13 described in fig. 2. In addition, the outer surface of the second conductive portion 23 of the present embodiment may be provided with an external thread, and the inner surface of the connection hole 12 may be provided with an internal thread.
In another embodiment of the present invention, as shown in fig. 6, one end of the second conductive portion 33 is a bump 331, wherein the cross-sectional area of the bump 331 is larger than that of the connection hole 12. Specifically, the second conductive portion 33 may be inserted into the connection hole 12 on the first surface 111 of the first conductive portion 11, wherein the bump 331 of the second conductive portion 33 is located on the first surface 111 of the first conductive portion 11, such that the bump 331 forms the protruding portion 131 on the first surface 111 of the first conductive portion 11. The bumps 331 of the second conductive portion 33 are used to connect the housing 151 of the battery cell 15, and the area and/or thickness of the eutectic portion 17 between the first conductive portion 11 and the housing 151 of the battery cell 15 can be increased to increase the connection strength between the first conductive portion 11 and the battery cell 15.
In addition, the outer surface of the second conductive portion 33 of the present embodiment may be provided with an external thread, and the inner surface of the connection hole 12 is provided with an internal thread, wherein the second conductive portion 33 can be locked on the second conductive portion 33 by the connection hole 12 on the first surface 111 of the first conductive portion 11, so that the bump 331 is located on the first surface 111 of the first conductive portion 11.
In the embodiment of the present invention, the second conductive portion 13/23/33 completely overlaps the first conductive portion 11 and protrudes from the first surface 111 (e.g., lower surface) of the first conductive portion 11. Therefore, when the battery frame 10 is connected to the housing 151 of the battery cell 15 through the second conductive part 13/23/33, a gap is formed between the first conductive part 11 and the connected battery cell 15, as shown in fig. 4. When the battery cell 15 is damaged to cause the gas of the battery liquid to be ejected, the ejected gas of the battery liquid can be discharged from the gap G between the first conductive part 11 and the battery cell 15, and the time or the chance of the battery liquid gas contacting the battery conductive frame 10 and/or other battery cells 15 is reduced, so as to reduce the damage to other battery cells 15.
In one embodiment of the present invention, the battery cell 15 may include a positive electrode 152 and a negative electrode 154, and the positive electrode 152 and the negative electrode 154 of the battery cell 25 are separated by an insulating ring 155. Specifically, the positive pole 152 of the cell 15 is located within the insulating ring 155, and the negative pole 154 is located outside the insulating ring 155.
Generally, when the battery cell 15 fails, the battery fluid gas inside the battery cell 15 is usually blown out of the battery cell 15 from the insulating ring 155 located between the positive electrode 152 and the negative electrode 154. In the embodiment of the present invention, since the second conductive part 13 is connected to only the positive electrode 152 inside the insulating ring 155, there is a gap between the first conductive part 11 and the insulating ring 155 and the casing 151 of the battery cell 15, so that the battery liquid gas jetted from the battery cell 15 can be transmitted to the outside through the gap G.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, which is defined by the appended claims, and all changes and modifications that fall within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
