In the related art, the battery cell can prevent electric leakage by arranging the insulating piece, so that the insulating safety performance of the battery cell is improved. The insulator can laminate with end cover, mass flow body respectively on the assembly, simultaneously, can set up the convex part etc. that is used for supporting the mass flow body on the insulator, will lead to insulator overall structure complicacy like this, and weight is great, and then increases 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 setting purpose of this application is just in order to solve this kind of problem, combines fig. 1 ~ 8 to set forth below.
The application discloses battery cell can include: the case 30, the electrode assembly 20, the cap assembly 10, and the current collector 200.
The case 30 provides shielding protection for the battery cell, and in particular, 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 case 30, thereby performing a sealing function to prevent external stains from being impregnated into the inside of the battery cell, and the end cap 300 is generally made of a metal material such as aluminum. The insulating member 100 has an insulating protection function, 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 disposed through in a thickness direction Z of the insulating member 100, and the groove 120 is disposed 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 through 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 electrode post 400, and the second current collecting portion 220 is received in the recess 120 to connect the electrode assembly 20, such that the electrode assembly 20, the current collector 200, and the electrode post 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 insulating member 100 has a hollow structure with multiple grooves by forming the through hole 110 and the groove 120, so that 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 mounted with the insulating member 100, and further reducing the thickness of the end cap assembly 10.
In the second aspect, the insulator 100 and the current collector 200 are multiplexed in height space by the accommodation of the current collector 200 by the through-hole 110 and the groove 120, thereby achieving the thinning of the cap assembly 10 mounted with the insulator 100 and the current collector 200, and thus achieving the thinning of the cap assembly 10.
In the third aspect, based on the light-weight design of the end cover assembly 10, the overall weight of the battery cell can be reduced, and meanwhile, due to the thinned design of the end cover assembly 10, the space occupation ratio of the end cover assembly 10 in the battery cell can be reduced, and the space utilization rate of the battery cell can be improved.
Alternatively, the through hole 110 may have a first limiting surface 111 and a second limiting surface 112 disposed opposite to each other in 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 engagement with the first limiting surface 111 and the second limiting surface 112 in the first direction X.
The recess 120 may have a third limiting surface 121 and a fourth limiting surface 122 disposed opposite to each other 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 engagement 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 cells intersect each other, for example, perpendicular to each other. For example, in fig. 1, the outer shape of the insulating member 100 is cylindrical, so that the first direction X and the second direction Y may be understood as radial directions of the insulating member 100, but the directions in the horizontal directions are different, and the height direction Z of the battery cell may be understood as axial directions of the insulating member 100.
As such, the through-hole 110 may form a constraint on the first current collecting portion 210 toward the first direction X, thereby limiting the shaking of the current collector 200 that may occur in the first direction X. And the groove 120 may form a constraint on the second current collecting portion 220 toward 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 the arrangement of the insulating member 100 can form limit and constraint on the current collector 200 in different directions, so as to better fix the current collector 200, reduce the possibility of shaking the current collector 200, and further improve the stability of the current collector 200 in the end cover assembly 10.
Similarly, since the through hole 110 has limited 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, so that the groove 120 can be disposed through in the first direction X to remove more materials on the insulating member 100, which is more beneficial to weight reduction of the insulating member 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 accommodation and restraint of the second current collecting portion 220.
Optionally, the insulating member 100 is provided with a liquid injection channel 130, the end cover 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 channel 130, so that electrolyte can flow into the inner cavity 31 through the liquid injection hole 310 and the liquid injection channel 130 in sequence, thereby realizing liquid injection to the battery cell.
Alternatively, the injection flow channel 130 may directly communicate with the inner cavity 31, or may indirectly communicate with the inner cavity 31, such as shown in fig. 2 and 7, in this application, the injection flow channel 130 communicates with the through hole 110, and communicates with the inner cavity 31 through the through hole 110, that is, the electrolyte may flow into the inner cavity 31 through the injection hole 310, the injection flow channel 130, and the through hole 110 in sequence. This allows multiplexing of the through holes 110, thereby simplifying the design of the insulator 100.
Alternatively, the injection flow path 130 may be provided in two, and symmetrically provided at opposite sides of the through hole 110. In this manner, not only can more material of the insulator 100 be subtracted to facilitate weight reduction, but also the insulator 100 can remain aligned with the end cap 300 in both the 0 ° and 180 ° positions during assembly of the end cap assembly 10, i.e., with both 0 ° and 180 ° mounting orientations, making installation easier.
Alternatively, as shown in fig. 2, the insulator 100 may be provided with recesses 140, the recesses 140 being spaced apart from the through holes 110. The arrangement of the concave 140 can improve the hollow degree of the insulating piece 100, and further remove the material on the insulating piece 100, thereby being more beneficial to the weight reduction of the insulating piece 100; meanwhile, the recess 140 is provided to increase the surface area of the insulating member 100, thereby increasing the heat dissipation area of the insulating member 100 and further improving the heat dissipation performance of the insulating member 100.
Alternatively, the recesses 140 may be provided in a plurality and symmetrically distributed on both sides of the through hole 110, so that more material on the insulating member 100 can be removed and the heat dissipation area of the insulating member 100 can be further increased.
Alternatively, the recess 140 may be provided at a side of the insulating member 100 facing away from the recess 120; the insulator 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 matched with the end cover 300 of the battery in a positioning way through a positioning piece, for example, the positioning piece is a positioning pin, one end of the positioning pin is fixed on the end cover 300, and the other end of the positioning pin penetrates through the through hole 150 to position the insulating piece 100; for example, the positioning member is a bolt, and the bolt penetrates through the through hole 150 and is screwed with the end cover 300, so as to position the insulating member 100; for example, the positioning member is a rivet, and the rivet sequentially penetrates through the through hole and the end cover 300, so that the insulating member 100 and the end cover 300 are riveted into a whole, and positioning of the insulating member 100 is realized; it can be seen that the positioning member can prevent abnormal rotation of the insulating member 100 relative to the end cap 300, and improve stability of the insulating member 100.
Meanwhile, the through holes 150 communicate with the recess 140 and the inner cavity 31, respectively, so that the electrolyte flowing into the through holes 150 can be guided to flow back into the inner cavity 31, thereby preventing the electrolyte from being retained in the recess 140, resulting in waste of the electrolyte and corrosion of the recess 140.
The application also discloses electric equipment, which is illustrated by taking the electric equipment as an automobile, wherein the automobile can be a fuel oil automobile, a fuel gas automobile or a new energy automobile, and the new energy automobile can be a pure electric automobile, a hybrid electric automobile or a range-extended automobile and the like. The automobile includes a battery, a controller, and a motor. The battery is used to supply power to the controller and motor as an operating power source and a driving power source for the automobile, for example, the battery is used for the power consumption for operation at the time of starting, navigation, and running of the automobile. For example, the battery supplies power to the controller, the controller controls the battery to supply power to the motor, and the motor receives and uses the power of the battery as a driving power source for the automobile to supply driving power to the automobile instead of or in part instead of fuel oil or natural gas. The electric equipment comprises the battery monomer.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
