In the related art, the single battery can prevent electric leakage by arranging the insulating piece, and further improve the insulation safety performance of the single battery. The insulating part is in the assembly, usually can laminate with the end cover respectively, the mass flow body, simultaneously, can set up the convex part etc. that is used for supporting the mass flow body on the insulating part, will lead to insulating part overall structure complicated like this, and weight is great, and then increase the weight of end cover subassembly to will make the free whole height of battery great, be unfavorable for the free attenuate of battery, the purpose that sets up of this application, just in order to solve this kind of problem, combine figure 1 ~ 8 below to illustrate.
The application discloses battery monomer can include: case 30, electrode assembly 20, end cap assembly 10, and current collector 200.
The case 30 provides shielding protection for the battery cell, and specifically, the case 30 may be provided with an inner cavity 31 and an opening communicating with the inner cavity 31, and the electrode assembly 20 as an energy storage component of the battery cell may be provided in the inner cavity 31.
The end cap assembly 10 may include: end cap 300, insulator 100 and post 400. The end cap 300 covers the opening of the housing 30, so as to seal the opening and prevent external contaminants from entering the interior of the battery cell, and the end cap 300 is usually made of a metal material such as aluminum. The insulating member 100 has an insulating protection function, and specifically, the insulating member 100 may be stacked on a side of the end cap 300 facing the electrode assembly 20, and the insulating member 100 is provided with a through hole 110 and a groove 120, the through hole 110 is arranged to penetrate in the thickness direction Z of the insulating member 100, and the groove 120 is arranged on a surface of the insulating member 100 facing the electrode assembly 20 in the thickness direction Z and communicates with the through hole 110. The pole 400 is inserted into the end cap 300, and at least a portion of the pole 400 is located in the through hole 110.
The current collector 200 may include a first current collecting portion 210 and a second current collecting portion 220 connected to each other, wherein the first current collecting portion 210 is received in the through hole 110 to connect the terminal 400, and the second current collecting portion 220 is received in the groove 120 to connect the electrode assembly 20, such that the electrode assembly 20, the current collector 200, and the terminal 400 are electrically connected in sequence, thereby forming a conductive loop to electrically conduct the battery cell.
It can be seen that, in the first aspect, the through hole 110 and the groove 120 are formed in the insulating member 100, so that the insulating member 100 has a multi-grooved hollow structure, and the material of the insulating member 100 can be removed as much as possible, thereby reducing the weight of the insulating member 100, further reducing the weight of the end cap assembly 10 on which the insulating member 100 is mounted, and further realizing the thinning of the end cap assembly 10.
In the second aspect, the current collector 200 is accommodated in the through-hole 110 and the recess 120, so that the insulator 100 and the current collector 200 share a high space, and the end cap assembly 10 having the insulator 100 and the current collector 200 mounted thereon is thinned, and thus the end cap assembly 10 is thinned.
In a third aspect, based on the light weight design of the end cap assembly 10, the overall weight of the battery cell can be reduced, and the thinning design of the end cap assembly 10 can reduce the space occupation ratio of the end cap assembly 10 in the battery cell, thereby improving the space utilization ratio of the battery cell.
Alternatively, the through hole 110 may have a first limiting surface 111 and a second limiting surface 112 oppositely disposed toward the first direction X, and the first current collecting portion 210 is located between the first limiting surface 111 and the second limiting surface 112 and is in limiting fit with the first limiting surface 111 and the second limiting surface 112 toward the first direction X.
The groove 120 may have a third limiting surface 121 and a fourth limiting surface 122 oppositely disposed in the second direction Y, and the second current collecting portion 220 is located between the third limiting surface 121 and the fourth limiting surface 122 and is in limiting fit with the third limiting surface 121 and the fourth limiting surface 122 in the second direction Y.
The first direction X, the second direction Y and the height direction Z of the battery cell intersect with each other, for example, are perpendicular to each other. For example, the shape of the insulating member 100 in fig. 1 is cylindrical, so the first direction X and the second direction Y can be understood as the radial direction of the insulating member 100, but the orientation in the horizontal direction is different, and the height direction Z of the battery cell can be understood as the axial direction of the insulating member 100.
As such, the through-hole 110 may form a constraint on the first current collecting portion 210 in the first direction X, thereby limiting a possible shaking of the current collector 200 in the first direction X. And the groove 120 may form a restriction on the second current collecting portion 220 in the second direction Y, thereby limiting the shaking of the current collector 200 that may occur in the second direction Y.
It can be seen that, due to the arrangement of the insulating member 100, the current collector 200 can be limited and restrained in different directions, so that the current collector 200 can be better fixed, the possibility of shaking of the current collector 200 is reduced, and the stability of the current collector 200 in the end cap assembly 10 is further improved.
Similarly, since the through hole 110 already limits the current collector 200 in the first direction X, the design of the groove 120 does not need to consider the limitation problem in the first direction X, and therefore the groove 120 may be disposed to penetrate toward the first direction X, so as to remove more material on the insulator 100, which is more beneficial to reducing the weight of the insulator 100.
Alternatively, the grooves 120 may be symmetrically provided at both sides of the through hole 110 to remove more material to achieve weight reduction of the insulator 100 and better to achieve accommodation and restraint of the second current collecting portion 220.
Optionally, the insulating member 100 is provided with a liquid injection flow channel 130, the end cap 300 is provided with a liquid injection hole 310, and the liquid injection hole 310 is communicated with the inner cavity 31 through the liquid injection flow channel 130, so that the electrolyte can flow into the inner cavity 31 through the liquid injection hole 310 and the liquid injection flow channel 130 in sequence, thereby realizing the liquid injection of the battery cell.
Alternatively, the injection flow channel 130 may be directly connected to the inner cavity 31 or indirectly connected to the inner cavity 31, for example, as shown in fig. 2 and 7, in this application, the injection flow channel 130 is connected to the through hole 110 and is connected to the inner cavity 31 through the through hole 110, that is, the electrolyte may sequentially flow into the inner cavity 31 through the injection hole 310, the injection flow channel 130 and the through hole 110. This allows multiplexing of the through-holes 110, thereby simplifying the design of the insulator 100.
Alternatively, two injection flow channels 130 may be provided, and are symmetrically provided on opposite sides of the through hole 110. In this manner, not only can more material be removed from the insulator 100 to facilitate weight reduction, but also the insulator 100 can be maintained in alignment with the end cap 300 in both the 0 ° position and the 180 ° position during assembly of the end cap assembly 10, i.e., both the 0 ° and 180 ° mounting orientations of the insulator 100, making installation easier.
Alternatively, as shown in fig. 2, the insulating member 100 may be provided with a recess 140, and the recess 140 is spaced apart from the through-hole 110. The arrangement of the recess 140 can improve the hollow degree of the insulating member 100, and further remove the material on the insulating member 100, thereby being more beneficial to reducing the weight of the insulating member 100; meanwhile, the recess 140 can increase the surface area of the insulating member 100, so as to increase the heat dissipation area of the insulating member 100, thereby improving the heat dissipation performance of the insulating member 100.
Alternatively, the recesses 140 may be disposed in a plurality and symmetrically distributed on both sides of the through hole 110, which can remove more material on the insulating member 100 and further increase the heat dissipation area of the insulating member 100.
Alternatively, the recess 140 may be provided on a side of the insulator 100 facing away from the recess 120; the insulating member 100 is further provided with a through hole 150, and the through hole 150 is provided at the bottom of the recess 140.
The through hole 150 is in positioning fit with the end cover 300 of the battery through a positioning member, for example, the positioning member is a positioning pin, one end of the positioning pin is fixed to the end cover 300, and the other end of the positioning pin penetrates through the through hole 150 to position the insulating member 100; for another example, the positioning element is a bolt, and the bolt penetrates through the through hole 150 and is in threaded connection with the end cover 300 to position the insulating element 100; for another example, the positioning element is a rivet, and the rivet sequentially penetrates through the through hole and the end cover 300, so that the insulating element 100 and the end cover 300 are riveted into a whole, and the positioning of the insulating element 100 is realized; it can be seen that the positioning member is provided to prevent the insulation member 100 from abnormally rotating with respect to the end cap 300, thereby improving the stability of the insulation member 100.
Meanwhile, the through-holes 150 communicate with the recess 140 and the cavity 31, respectively, so that the electrolyte flowing into the through-holes 150 can be guided to flow back into the cavity 31, preventing the electrolyte from staying in the recess 140, causing waste of the electrolyte and corrosion of the recess 140.
The application also discloses consumer, explains with the consumer as the car for the example, and the car can be fuel oil car, gas car or new energy automobile, and the new energy automobile can be pure electric, hybrid vehicle or increase form car etc.. An automobile includes a battery, a controller, and a motor. The battery is used to supply power to the controller and the motor as an operation power source and a driving power source of the automobile, for example, the battery is used for power demand for operation in starting, navigation and running of the automobile. For example, a battery supplies power to a controller, the controller controls the battery to supply power to a motor, and the motor receives and uses the power of the battery as a driving power source of the automobile instead of or in part replacing fuel or natural gas to provide driving power for the automobile. The electric equipment comprises the battery cell.
