[0004] The battery injection and infiltration process is one of the important process steps in the battery production process to ensure battery performance and cycle life. During the battery production process, the internal materials of the battery must be infiltrated with electrolyte before they can be charged. The purpose of infiltration is to allow the electrolyte to fill the gaps between the particles of the electrode material inside the battery and the pores of the diaphragm material, thereby ensuring the safety and electrical performance of the battery. The role of the electrolyte is to conduct ions between the positive and negative electrodes and act as a medium for charging and discharging.

[0005] In related technologies, to allow the electrolyte to soak into the electrode and separator, after injecting the electrolyte into the battery, the battery is left to stand. This allows the electrolyte to rise through the electrode, separator, and other parts of the electrode due to capillary action, wetting different parts of the electrode. However, this method of soaking the internal materials of the battery requires the battery to sit for a long time, which reduces the soaking efficiency, consumes a lot of time, and reduces the battery production efficiency.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present application. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0024] As shown in Figure 1, the battery-assisted impregnation device 100 includes a carrier and a pressure regulating mechanism 20. A accommodating cavity for accommodating the battery 200 is provided inside the carrier. The pressure regulating mechanism 20 is connected to the carrier and communicated with the accommodating cavity. The pressure regulating mechanism 20 is used to adjust the pressure in the accommodating cavity so that the battery 200 produces elastic deformation.

[0025] In an embodiment of the present application, the battery-assisted infiltration device 100 includes a carrier and a pressure regulating mechanism 20, wherein the carrier has a storage chamber inside, and the battery 200 can be accommodated through the storage chamber. The pressure regulating mechanism 20 is connected to the carrier and is in communication with the storage chamber. Therefore, the pressure in the storage chamber can be adjusted by operating the pressure regulating mechanism 20 to increase or decrease the pressure in the storage chamber. When the battery 200 is accommodated in the storage chamber and the pressure in the storage chamber increases, the battery 200 is squeezed and elastically deformed. At this time, the electrolyte inside the battery 200 is also squeezed, which can enhance the fluidity of the electrolyte and allow the electrolyte to fully contact the components inside the battery 200, thereby improving the infiltration efficiency of the electrolyte; when the pressure in the storage chamber decreases, the battery 200 can restore the deformation, and the battery 200 can be removed from the storage chamber. That is, the present application can adjust the pressure in the accommodating cavity through the pressure regulating mechanism 20, increase the fluidity of the electrolyte, and allow the electrolyte to be forced to fully contact the components inside the battery 200, thereby improving the infiltration efficiency of the electrolyte, reducing the time cost of infiltration of the internal components of the battery 200, and improving the production efficiency of the battery 200.

[0026] It should be noted that after the battery 200 is placed in the receiving chamber, the pressure in the receiving chamber can be increased by the pressure regulating mechanism 20. At this time, the force applied to the battery 200 can squeeze the electrolyte inside, allowing the electrolyte to fully contact the electrode, diaphragm, and other components. The squeezing of the battery 200 can also provide a certain internal driving force to the electrolyte, facilitating the electrolyte to overcome the gas phase resistance within the electrode and diaphragm and enter the electrode and diaphragm, thereby improving the electrolyte infiltration efficiency. To further improve the electrolyte infiltration efficiency, during the infiltration process, the pressure regulating mechanism 20 can cyclically pressurize the receiving chamber. For example, the pressure of the receiving chamber can be first increased and then decreased. After the pressure drops to normal pressure, the pressure of the receiving chamber can be increased again and then decreased again, repeating the pressure increase and decrease process. During this process, the electrolyte can also be repeatedly subjected to force, repeatedly contacting the electrode, diaphragm, etc., allowing the electrode and diaphragm to fully absorb the electrolyte, further improving the fluidity of the electrolyte within the battery 200, shortening the infiltration time, and improving the infiltration efficiency. Alternatively, during the infiltration process, the pressure regulating mechanism 20 may cyclically pressurize the containment chamber in other ways. For example, the pressure in the containment chamber may be increased first. When the pressure in the containment chamber reaches a first set value, the pressure regulating mechanism 20 stops operating, maintaining the pressure in the containment chamber constant. After maintaining the pressure for a preset period of time, the pressure in the containment chamber is reduced. After the pressure drops to normal pressure, the pressure in the containment chamber may be increased again, and then the pressure in the containment chamber may be maintained and then reduced. In other words, the containment chamber may be repeatedly pressurized, maintained, and reduced to improve the fluidity of the electrolyte within the battery 200, shorten the infiltration time, and improve the infiltration efficiency.

[0027] It should also be noted that the existing battery 200 shell is a thin aluminum shell, which makes the battery 200 shell elastically deformable. The present application can take advantage of the elastic deformation of the thin aluminum shell to apply force to the electrolyte inside through the thin aluminum shell, so that the electrolyte can fully contact the electrode, diaphragm, etc.

[0028] In addition, in some embodiments, as shown in Figure 1, the pressure regulating mechanism 20 may include a first pipeline 22 and a first switch 21, one end of the first pipeline 22 is connected to the accommodating chamber, and the other end of the first pipeline 22 is used to connect to the gas source. The first switch 21 is arranged in the first pipeline 22, and the first switch 21 is used to control the first pipeline 22 to be turned on or off so as to introduce gas into the accommodating chamber through the gas source.

[0029] The pressure regulating mechanism 20 includes a first pipeline 22, one end of which is connected to the accommodating chamber, and the other end of the first pipeline 22 is used to connect to the gas source, that is, the first pipeline 22 is connected to the accommodating chamber and the gas source. The gas source can pass gas into the accommodating chamber through the first pipeline 22 to increase the pressure in the accommodating chamber so that the electrolyte is in full contact with the electrode and the diaphragm.

[0030] The pressure regulating mechanism 20 also includes a first switch 21, which is disposed on a first conduit 22. The first switch 21 can be used to control the opening or closing of the first conduit 22, thereby connecting the gas source and the accommodating chamber, or disconnecting the connection between the gas source and the accommodating chamber. When the first switch 21 is on, the first conduit 22 can be connected, and the gas source and the accommodating chamber are connected, allowing the gas source to flow into the accommodating chamber, thereby increasing the pressure in the accommodating chamber. When the first switch 21 is off, the first conduit 22 can be disconnected, and the gas source and the accommodating chamber are disconnected, preventing the gas source from continuing to flow into the accommodating chamber.

[0031] It should be noted that the gas source is a device that can provide compressed gas to the accommodating chamber, such as a compressor, an air pump, etc. The specific form of the gas source is not specifically limited in the embodiments of the present application.

[0032] In addition, in some embodiments, as shown in Figure 1, the pressure regulating mechanism 20 may further include a second pipeline 24 and a second switch 23, one end of the second pipeline 24 is connected to the accommodating chamber, and the other end of the second pipeline 24 is located outside the accommodating chamber. The second switch 23 is arranged in the second pipeline 24, and the second switch 23 is used to control the conduction or disconnection of the second pipeline 24 to release the gas in the accommodating chamber through the second pipeline 24.

[0033] The pressure regulating mechanism 20 includes a second pipeline 24, one end of which is connected to the accommodating chamber, and the other end of the second pipeline 24 is located outside the accommodating chamber, that is, the accommodating chamber and the space outside the accommodating chamber can be connected through the second pipeline 24, so that the gas in the accommodating chamber can be released through the second pipeline 24 to reduce the pressure in the accommodating chamber.

[0034] The pressure regulating mechanism 20 also includes a second switch 23 disposed within a second conduit 24. The second switch 23 can be used to control the opening or closing of the second conduit 24, thereby connecting the accommodating chamber to the space outside of the chamber, or disconnecting the connection between the accommodating chamber and the space outside of the chamber. When the second switch 23 is on, the second conduit 24 is open, allowing the accommodating chamber and the space outside of the chamber to communicate, allowing gas in the accommodating chamber to be released through the second conduit 24, thereby reducing the pressure in the chamber. When the second switch 23 is off, the second conduit 24 is disconnected, disconnecting the accommodating chamber and the space outside of the chamber, preventing gas from being released through the second conduit 24.

[0035] Specifically, the pressure regulating mechanism 20 includes a first switch 21, a second switch 23, a first pipeline 22, and a second pipeline 24. The first switch 21 and the first pipeline 22 can cooperate to increase the pressure in the accommodating chamber, while the second switch 23 and the second pipeline 24 can cooperate to reduce the pressure in the accommodating chamber. The pressure in the accommodating chamber can be adjusted by controlling the first switch 21 and the second switch 23. When the first switch 21 is on and the second switch 23 is off, the gas source is connected to the accommodating chamber, increasing the pressure in the accommodating chamber. When the first switch 21 is off and the second switch 23 is on, the external space of the accommodating chamber is connected to the accommodating chamber, decreasing the pressure in the accommodating chamber. When the first switch 21 and the second switch 23 are off, the accommodating chamber is sealed, and the pressure in the accommodating chamber remains unchanged.

[0036] It should be noted that the first switch 21 and the second switch 23 can be switch valves, control valves and other components that can be controlled to open and close. The specific types of the first switch 21 and the second switch 23 are not specifically limited in this embodiment of the application.

[0037] It should also be noted that the second pipe 24 may not be provided. Instead, a through hole may be provided on the carrier, and the second switch 23 may be provided at the through hole. When the second switch 23 is turned on, the gas may leak through the through hole. The provision of the second pipe 24 in the embodiment of the present application can guide the gas and prevent it from leaking into the working environment of the auxiliary infiltration device of the battery 200.

[0038] In addition, in some embodiments, as shown in FIG1 , the battery-assisted infiltration device 100 may further include a control component 30 , which is communicatively connected to the first switch 21 and the second switch 23 , and is used to control the first switch 21 and the second switch 23 to be opened or closed.

[0039] The battery-assisted infiltration device 100 also includes a control component 30, wherein the control component 30 is communicatively connected to the first switch 21 and the second switch 23. Therefore, the first switch 21 and the second switch 23 can be controlled to open or close by the control component 30, which facilitates automatic control of the first switch 21 and the second switch 23, thereby facilitating the adjustment of the pressure in the accommodating chamber and avoiding the complex operation of requiring the user to manually control the first switch 21 and the second switch 23 to open or close.

[0040] It should be noted that the communication connection between the control component 30 and the first switch 21 and the second switch 23 can be carried out in a variety of ways. For example, a signal line can be connected between the first switch 21 and the control component 30 to achieve a wired communication connection between the first switch 21 and the control component 30. Of course, a signal line can also be connected between the second switch 23 and the control component 30. Alternatively, the first switch 21 and the second switch 23 can also be communicated wirelessly, for example, through Bluetooth, wireless communication technology (Wireless Fidelity, Wi-Fi), etc. The specific method of communication connection is not specifically limited in the embodiment of the present application and can be selected according to actual circumstances. Among them, the communication connection methods between the first switch 21, the second switch 23 and the control component 30 can be different.

[0041] In addition, in some embodiments, as shown in Figure 1, the pressure regulating mechanism 20 may further include a pressure detecting component 25, which is arranged on the carrier and connected to the accommodating cavity. The pressure detecting component 25 is communicated with the control component 30. The pressure detecting component 25 is used to detect the pressure in the accommodating cavity, and the control component 30 is used to control the opening and closing of the first switch 21 and / or the second switch 23 based on the pressure.

[0042] The pressure regulating mechanism 20 also includes a pressure detecting component 25, which is arranged on the carrier. Since the pressure detecting component 25 is connected to the accommodating chamber, the pressure in the accommodating chamber can be detected by the pressure detecting component 25, so that the operation of the pressure regulating mechanism 20 can be controlled according to the pressure in the accommodating chamber.

[0043] Since the pressure detection component 25 is also communicatively connected to the control component 30, the pressure detection component 25 can transmit the detected pressure to the control component 30. After receiving the pressure transmitted by the pressure detection component 25, the control component 30 can control the opening and closing of the first switch 21 and / or the second switch 23 based on the pressure, and adjust the pressure in the accommodating chamber, which can facilitate the regulation of the pressure in the accommodating chamber.

[0044] In addition, in some embodiments, as shown in Figure 1, the carrier may include a main body 11, a cover body 12 and an opening and closing module 40, the opening and closing module 40 is connected to the cover body 12, the cover body 12 is movably connected to the main body 11, and the opening and closing module 40 is used to drive the cover body 12 to move so that the cover body 12 and the main body 11 are enclosed to form a accommodating cavity, or at least part of the cover body 12 is separated from the main body 11.

[0045] The carrier includes a main body 11, a cover 12 and an opening and closing module 40, wherein the cover 12 is movably connected to the main body 11, and the cover 12 can be operated to move relative to the main body 11 so that the cover 12 can be connected to the main body 11. At this time, the carrier is closed, and a storage cavity for accommodating the battery 200 can be formed between the cover 12 and the main body 11; or at least part of the cover 12 can be separated from the main body 11. At this time, the carrier is opened, and the battery 200 can be placed in the carrier or taken out of the carrier.

[0046] Among them, the opening and closing module 40 is connected to the cover body 12, and the cover body 12 can be driven to move by the opening and closing module 40, so that the cover body 12 can be enclosed with the main body 11 to form a accommodating cavity, or at least part of the cover body 12 can be separated from the main body 11, so that the carrier can switch between the closed and open states.

[0047] It should be noted that a chamber with an opening can be provided in the main body 11, and the cover 12 is movably connected to the main body 11 and can be moved to the opening to seal the chamber. At this time, the cover 12 and the main body 11 can form a closed accommodating chamber; or it can be moved until it is at least partially separated from the opening. At this time, the opening of the chamber is exposed, and the battery 200 can be removed from the carrier or placed into the carrier through the opening.

[0048] It should also be noted that the cover body 12 and the main body 11 can be connected in different ways. For example, the cover body 12 can be rotatably connected to the main body 11. In this case, the opening and closing module 40 is a rotatable component, such as a rotary motor. The output shaft of the rotary motor can be connected to the cover body 12, and the cover body 12 can be driven to rotate by the output shaft of the rotary motor; or, the cover body 12 can be slidably connected to the main body 11, that is, the cover body 12 can move relative to the main body 11. In this case, the opening and closing module 40 is a component that can output linear motion, such as a linear motor, a linear cylinder, etc., and the cover body 12 can be connected by a linear motor, a linear cylinder, etc. to drive the cover body 12 to move.

[0049] In addition, in order to ensure that the driving member 41 such as the above-mentioned rotary motor, linear motor, linear cylinder, etc. drives the cover body 12 in accordance with the use requirements, avoid the cover body 12 from moving too fast or too slow, and enable the driving member 41 to apply sufficient power to the cover body 12, a transmission member 42 can also be provided, and the transmission member 42 is connected between the cover body 12 and the driving member 41, and the force of the driving member 41 is transmitted to the cover body 12 through the transmission member 42.

[0050] In addition, in some embodiments, as shown in Figure 1, the opening and closing module 40 can be communicated with the control component 30, and the control component 30 is used to control the opening and closing module 40 to run or stop, so that the cover body 12 and the main body 11 are enclosed to form a accommodating cavity, or part of the cover body 12 is separated from the main body 11.

[0051] The opening and closing module 40 is communicatively connected to the control component 30, and the opening and closing module 40 can be controlled to run or stop by the control component 30, which facilitates automatic control of the opening and closing module 40, thereby facilitating control of the cover body 12, avoiding the user's need to manually control the movement of the cover body 12 to open or close the vehicle. The complicated process of the vehicle.

[0052] It should be noted that the communication connection between the control component 30 and the opening and closing module 40 can be carried out in a variety of ways. For example, a signal line can be connected between the opening and closing module 40 and the control component 30 to realize a wired communication connection between the opening and closing module 40 and the control component 30; or, the opening and closing module 40 can also be communicated in a wireless manner, for example, through Bluetooth, Wi-Fi, etc. The specific method of communication connection is not specifically limited in the embodiment of the present application, and can be selected for use according to actual conditions.

[0053] It should also be noted that when the opening and closing module 40 includes a driving member 41, for example, it may include one of a rotary motor, a linear motor, a linear cylinder, etc., and the communication connection between the control component 30 and the opening and closing module 40 can be specifically a communication connection between the control component 30 and the driving member 41; when the opening and closing module 40 includes a driving member 41 and a transmission member 42, the communication connection between the control component 30 and the opening and closing module 40 can be specifically a communication connection between the control component 30 and the driving member 41.

[0054] In addition, in some embodiments, the control component 30 may include a control unit and a detection unit. The opening and closing module 40, the detection unit, the first switch 21, and the second switch 23 are all communicatively connected to the control unit. The detection unit is used to detect the position of the cover body 12, and the control unit is used to control the opening and closing module 40 to run or stop according to the position.

[0055] The control assembly 30 includes a control unit and a detection unit. The opening and closing module 40, the first switch 21, and the second switch 23 are all communicatively connected to the control unit, and the control unit can control the opening and closing module 40, the first switch 21, and the second switch 23. The detection unit can detect the position of the cover 12. Since the detection unit is also communicatively connected to the control unit, the detection unit can send the position of the cover 12 to the control unit, and the control unit is used to control the opening and closing module 40 to start or stop according to the position.

[0056] Specifically, after receiving the position sent by the detection unit, the control unit can determine whether the cover 12 has moved into position based on the position, and then control the opening and closing module 40 to operate or stop. For example, when it is necessary to open the vehicle, the control unit can send an opening signal to the opening and closing module 40. After receiving the opening signal, the opening and closing module 40 can operate to cause the cover 12 to start moving. When the cover 12 moves, the detection unit can detect the position of the cover 12. When the cover 12 moves to expose the opening, the detection unit can feedback a signal of opening completion to the control unit. After receiving the signal of opening completion, the control unit can control the opening and closing module 40 to stop operating, completing the opening of the vehicle. When it is necessary to close the vehicle, the control unit can send a closing signal to the opening and closing module 40. After receiving the closing signal, the opening and closing module 40 can reverse and cause the cover 12 to start moving. When the cover 12 moves, the detection unit can detect the position of the cover 12. When the cover 12 moves to completely block the opening, the detection unit can feedback a signal of closing completion to the control unit. After receiving the signal of closing completion, the control unit can control the opening and closing module 40 to stop operating, completing the closing of the vehicle.

[0057] It should be noted that the detection unit can be a position sensor, which can be specifically set on the outside of the carrier and opposite to the opening on the body 11, and can detect whether there is a cover 12 at the opening and the movement of the cover 12 at the opening; alternatively, the detection unit can also be set at the driver 41 and located on the movement path of the output shaft of the driver 41. For example, when the driver 41 is a linear cylinder, the detection unit can be located on the movement path of the piston rod. The detection unit can detect whether the piston rod is extended or retracted into place, and problems with the cover 12 can also be detected based on the operation of the driver 41. The specific location of the detection unit is not specifically limited in the embodiments of the present application.

[0058] It should also be noted that when the driving member 41 is a linear cylinder, in order to detect the working status of the linear cylinder and ensure the normal operation of the linear cylinder, the control component 30 may also include a sensor. The sensor can be set in the rodless cavity or the rod cavity of the linear cylinder to detect the situation of the linear cylinder receiving gas.

[0059] To make the purpose, technical solutions, and beneficial effects of this application more clear, the following describes the use process of the battery-assisted infiltration device 100 provided in the embodiments of this application to further describe this application. It should be understood that these embodiments are only used to illustrate this application and are not intended to limit the scope of this application.

[0060] Step 101: The control component sends an opening signal to the opening and closing module, and the opening and closing module drives the cover to move to open the carrier;

[0064] Step 105: After a preset time, the control component controls the second switch to turn on;

[0065] Step 106: The pressure detecting element detects the pressure in the accommodating chamber. When the pressure in the accommodating chamber is a second set value, the control component controls the second switch to be closed.

[0066] Step 107: Repeat steps 103 to 106 for a preset number of times;

[0067] Step 108 : The control component sends an opening signal to the opening and closing module, and the opening and closing module drives the cover to move to open the carrier and remove the battery 200 .

[0068] The first set value is greater than the second set value, the second set value may be normal pressure, i.e., standard atmospheric pressure, and the first set value may be 0.5 MPa, so that the air pressure can squeeze the battery 200. Of course, the first set value may also be other values, for example, 0.48 MPa, 0.46 MPa, 0.55 MPa, 0.52 MPa, etc. The specific value of the first set value is not specifically limited in this embodiment of the present application.

[0069] The preset duration can also be set according to actual needs, for example, it can be set to 60 seconds, 70 seconds, 79 seconds, 85 seconds, 90 seconds, etc. The specific value of the preset duration is not specifically limited in this embodiment of the application.

[0070] The preset number of times can also be set according to actual needs, for example, it can be set to 2, 3, 4, etc. The specific value of the preset number is not specifically limited in this embodiment of the present application. In the related art, the process of allowing the electrolyte to infiltrate the electrode and the diaphragm by leaving the battery 200 to stand still generally takes 8-36 hours. However, when the battery 200 is infiltrated using the battery auxiliary infiltration device 100 proposed in this application, it has been tested that if the process of increasing pressure, maintaining pressure, and releasing pressure is repeated twice, the time taken can be as low as 18 minutes, which can significantly reduce the time consumption.

[0071] In an embodiment of the present application, the battery-assisted infiltration device 100 includes a carrier and a pressure regulating mechanism 20, wherein the carrier has a storage chamber inside, and the battery 200 can be accommodated through the storage chamber. The pressure regulating mechanism 20 is connected to the carrier, and part of the pressure regulating mechanism 20 is connected to the storage chamber. Therefore, the pressure in the storage chamber can be adjusted by operating the pressure regulating mechanism 20 to increase or decrease the pressure in the storage chamber. When the battery 200 is accommodated in the storage chamber and the pressure in the storage chamber increases, the battery 200 is squeezed and elastically deformed. At this time, the electrolyte inside the battery 200 is also squeezed, which can enhance the fluidity of the electrolyte and allow the electrolyte to fully contact the components inside the battery 200, thereby improving the infiltration efficiency of the electrolyte; when the pressure in the storage chamber decreases, the battery 200 can restore the deformation, and the battery 200 can be taken out of the storage chamber. That is, the present application can adjust the pressure in the accommodating cavity through the pressure regulating mechanism 20, increase the fluidity of the electrolyte, and allow the electrolyte to be forced to fully contact the components inside the battery 200, thereby improving the infiltration efficiency of the electrolyte, reducing the time cost of infiltration of the internal components of the battery 200, and improving the production efficiency of the battery 200.

[0072] In addition, an embodiment of the present application also proposes an infiltration system, which includes a battery 200 and a battery-assisted infiltration device 100 in any of the above embodiments. The battery 200 is located in the accommodating cavity, and the pressure regulating mechanism 20 is used to adjust the pressure in the accommodating cavity so that the battery 200 produces elastic deformation.

[0073] The infiltration system includes a battery 200 and a battery auxiliary infiltration device 100, wherein the battery 200 is located in a accommodating chamber, and the pressure regulating mechanism 20 can adjust the pressure in the accommodating chamber. When the battery 200 is accommodated in the accommodating chamber and the pressure in the accommodating chamber increases, the battery 200 is squeezed by force. At this time, the electrolyte inside the battery 200 is also squeezed, which can enhance the fluidity of the electrolyte and allow the electrolyte to fully contact the components inside the battery 200, thereby improving the infiltration efficiency of the electrolyte; when the pressure in the accommodating chamber decreases, the battery 200 can restore its deformation, and the battery 200 can be removed from the accommodating chamber.

[0074] In addition, in some embodiments, as shown in Figures 2 and 3, the battery 200 may have a positive electrode sheet 203 and a negative electrode sheet 204 inside, and the positive electrode sheet 203 and the negative electrode sheet 204 are stacked along the first direction X. In the direction perpendicular to the first direction X, the battery 200 has a first surface 201 and a second surface 202 relative to each other, and the first surface 201 or the second surface 202 abuts against the bottom of the accommodating cavity.

[0075] The battery 200 may include a shell 206, which is filled with an electrolyte. The positive electrode sheet 203 and the negative electrode sheet 204 are stacked in the shell 206 along the first direction X. A diaphragm 207 is also provided between the positive electrode sheet 203 and the negative electrode sheet 204. The positive electrode sheet 203, the negative electrode sheet 204, and the diaphragm 207 form a core 205. The diaphragm 207 can isolate the positive electrode sheet 203 and the negative electrode sheet 204 to prevent the positive electrode sheet 203 and the negative electrode sheet 204 from contacting and short-circuiting.

[0076] Along the length of the battery 200, the housing 206 has opposing top and bottom portions. Between the top and bottom portions, the housing 206 also has two opposing wide sides and two opposing narrow sides. The two wide sides are oriented along the thickness of the battery 200, while the two narrow sides are oriented along the width of the battery 200. In the embodiment of the present application, the positive electrode tab 203 and the negative electrode tab 204 are arranged along the thickness of the battery 200, while the first side 201 and the second side 202 are arranged perpendicular to the first direction X, i.e., the two narrow sides mentioned above.

[0077] When the battery 200 is placed in the receiving cavity, the first surface 201 or the second surface 202 can abut against the bottom of the receiving cavity. The battery 200 is placed in the receiving cavity in a side-standing manner, with the width direction of the battery 200 parallel to the vertical direction. When the pressure in the receiving cavity is increased, the outer shell of the battery 200 squeezes the electrolyte inside, and the electrolyte moves upward in the vertical direction, which can contact and infiltrate the electrode and other components at a high position. In the solution of the stationary battery 200 in the related art, the electrolyte needs to slowly climb from the bottom to the top in the vertical direction to infiltrate the electrode and other components. Compared with the solution of the related art, the battery 200 in the present application can apply force to the electrolyte, so that the electrolyte moves to a high position, avoiding the process of the electrolyte slowly climbing. The electrolyte only needs to enter from the outside of the electrode and other components in the thickness direction. The original long-distance self-infiltration from bottom to top is changed to a short-distance infiltration along the thickness direction, which can improve the infiltration efficiency of the electrolyte.

[0078] In addition, the first surface 201 or the second surface 202 is placed downward in the accommodating cavity. At this time, the width direction of the battery 200 is parallel to the vertical direction, which can make the size of the battery 200 smaller in the vertical direction, making it easier for the electrolyte to rise under the squeezing action of the shell; of course, the top or bottom of the shell 206 can also be placed downward in the accommodating cavity. At this time, the length direction of the battery 200 is parallel to the vertical direction, and the battery 200 is in an upright state. In the vertical direction, the size of the battery 200 is larger. Compared with the case where the battery 200 is placed sideways, its infiltration efficiency is slightly reduced, but compared with the related art, the infiltration efficiency is still higher. Of course, the wide side can also be placed downward in the accommodating cavity, which can also improve the infiltration efficiency. The sideways placement proposed in this application is more convenient for taking the battery 200 than the method of placing the wide side downward.
