DETAILED DESCRIPTION

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

[0023] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

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

[0025] In an embodiment of the utility model, 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 communicated 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 by force to produce elastic deformation. 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 at this time. 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 internal components of the battery 200, thereby improving the infiltration efficiency of the electrolyte, reducing the time cost of infiltrating 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 battery 200 can be subjected to force to squeeze the electrolyte inside, so that the electrolyte is in full contact with the pole piece, diaphragm and other components, and the extrusion of the battery 200 can also give the electrolyte a certain internal driving force, which is convenient for the electrolyte to overcome the gas phase resistance in the pole piece and diaphragm and enter the inside of the pole piece and diaphragm, thereby improving the infiltration efficiency of the electrolyte. In order to further improve the infiltration efficiency of the electrolyte, 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 increased first, and then the pressure of the receiving chamber can be reduced; after the pressure is reduced to normal pressure, the pressure of the receiving chamber can be increased again, and then the pressure of the receiving chamber can be reduced again, and the process of increasing and reducing pressure can be repeated. In this process, the electrolyte can also be repeatedly subjected to force and repeatedly contact with the pole piece, diaphragm, etc., so that the pole piece and diaphragm can fully absorb the electrolyte, which can further improve the fluidity of the electrolyte inside the battery 200, shorten the infiltration time, and improve the infiltration efficiency. Alternatively, during the infiltration process, the pressure regulating mechanism 20 may also cyclically pressurize the accommodation chamber in other ways. For example, the pressure of the accommodation chamber may be increased first, and when the pressure of the accommodation chamber reaches a first set value, the pressure regulating mechanism 20 stops working, keeps the pressure in the accommodation chamber unchanged, and reduces the pressure of the accommodation chamber after maintaining the pressure for a preset time. After the pressure is reduced to normal pressure, the pressure of the accommodation chamber may be increased again, and then the pressure of the accommodation chamber may be maintained and reduced. That is, the process of increasing, maintaining, and reducing the pressure of the accommodation chamber may be repeated to improve the fluidity of the electrolyte inside 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 shell of the battery 200 have the property of elastic deformation. The present application can use the elastic deformation property of the thin aluminum shell to apply force to the internal electrolyte through the thin aluminum shell, so that the electrolyte can fully contact with the pole piece, the diaphragm, etc.

[0028] In addition, in some embodiments, Figure 1 As shown, 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. 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 the first pipeline 22. The first switch 21 can be used to control the first pipeline 22 to be connected or disconnected, so that the gas source and the accommodating chamber can be connected, or the connection between the gas source and the accommodating chamber can be disconnected. When the first switch 21 is turned on, the first pipeline 22 can be connected. At this time, the gas source and the accommodating chamber are connected, and the gas source can pass gas into the accommodating chamber to increase the pressure in the accommodating chamber; when the first switch 21 is turned off, the first pipeline 22 can be disconnected. At this time, the gas source and the accommodating chamber are not connected, and the gas source can no longer pass gas 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 embodiment of the utility model.

[0032] In addition, in some embodiments, Figure 1 As shown, the pressure regulating mechanism 20 may further include a second pipeline 24 and a second switch 23, wherein 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, and the second switch 23 is disposed in the second pipeline 24, and the second switch 23 is used to control the second pipeline 24 to be turned on or off so as 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 further includes a second switch 23, which is disposed in the second pipeline 24. The second switch 23 can be used to control the second pipeline 24 to be turned on or off, so that the accommodating chamber can be connected to the space outside it, or the connection between the accommodating chamber and the space outside it can be disconnected. When the second switch 23 is turned on, the second pipeline 24 can be turned on. At this time, the accommodating chamber and the space outside the accommodating chamber are connected, and the gas in the accommodating chamber can be released through the second pipeline 24 to reduce the pressure in the accommodating chamber; when the second switch 23 is turned off, the second pipeline 24 can be disconnected. At this time, the accommodating chamber and the space outside the accommodating chamber are not connected, and the gas cannot be released through the second pipeline 24.

[0035] That is, 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 of the accommodating chamber, and the second switch 23 and the second pipeline 24 can cooperate to reduce the pressure of 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 turned on and the second switch 23 is turned off, the gas source is connected to the accommodating chamber, which can increase the pressure in the accommodating chamber; when the first switch 21 is turned off and the second switch 23 is turned on, the external space of the accommodating chamber is connected to the accommodating chamber, which can reduce the pressure in the accommodating chamber; when the first switch 21 is turned off and the second switch 23 is turned off, the accommodating chamber is in a sealed state, 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 the embodiment of the utility model.

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

[0038] In addition, in some embodiments, Figure 1 As shown, 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 turned on or off.

[0039] The battery-assisted infiltration device 100 also includes a control component 30, wherein the control component 30 is communicatively connected with the first switch 21 and the second switch 23. Therefore, the first switch 21 and the second switch 23 can be controlled to be opened or closed by the control component 30, so as to facilitate 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 be opened or closed.

[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 realize 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; or, the first switch 21 and the second switch 23 can also be communicated and connected in a wireless manner, for example, wireless connection can be carried out 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 utility model, and can be selected and used according to actual conditions. 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, Figure 1 As shown, the pressure regulating mechanism 20 may further include a pressure detecting component 25, which is disposed on the carrier and connected to the accommodating cavity. The pressure detecting component 25 is communicatively connected to 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 disposed 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, thereby facilitating the operation of the pressure regulating mechanism 20 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, thereby adjusting the pressure in the accommodating chamber, thereby facilitating the regulation of the pressure in the accommodating chamber.

[0044] In addition, in some embodiments, Figure 1 As shown, 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 body 12 and an opening and closing module 40, wherein the cover body 12 is movably connected to the main body 11, and the cover body 12 can be operated to move relative to the main body 11 so that the cover body 12 can be connected to the main body 11. At this time, the carrier is closed, and a receiving cavity for accommodating a battery 200 can be formed between the cover body 12 and the main body 11; or at least a portion of the cover body 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 body 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 body 12 and the main body 11 can form a closed accommodating chamber; or it can be moved until at least partially separated from the opening, at this time the opening of the chamber is exposed, and the battery 200 can be taken out of 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 of the cover body 12 by the driving member 41 such as the above-mentioned rotating motor, linear motor, linear cylinder, etc. meets 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, so that 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, Figure 1 As shown, the opening and closing module 40 can be connected to the control component 30 for communication. 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 body 11 are enclosed to form a receiving cavity, or part of the cover body 12 is separated from the body 11.

[0051] The opening and closing module 40 is communicatively connected with the control component 30, and the opening and closing module 40 can be controlled to run or stop by the control component 30, so as to facilitate automatic control of the opening and closing module 40, thereby facilitating the 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 wirelessly, for example, wirelessly connected via Bluetooth, Wi-Fi, etc. The specific method of the communication connection is not specifically limited in the embodiment of the utility model, 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 rotating motor, a linear motor, a linear cylinder, etc., and the communication connection between the control component 30 and the opening and closing module 40 may specifically be 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 may specifically be 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 connected to the control unit for communication, 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 connected to the control unit for communication, 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 run or stop according to the position.

[0056] Specifically, after the control unit receives the position sent by the detection unit, it can determine whether the cover 12 has moved to the position according to 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, and the opening and closing module 40 can operate to make the cover 12 start to move after receiving the opening signal. 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 the opening completion signal to the control unit. After the control unit receives the opening completion signal, it can control the opening and closing module 40 to stop operating and complete 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 reversely operate to make the cover 12 start to move. When the cover 12 moves, the detection unit can detect the position of the cover 12. When the cover 12 moves to completely cover the opening, the detection unit can feedback the closing completion signal to the control unit. After the control unit receives the closing completion signal, it can control the opening and closing module 40 to stop operating and complete the closing of the vehicle.

[0057] It should be noted that the detection unit can be a position sensor, which can be specifically arranged outside 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; or, the detection unit can also be arranged at the driving member 41 and located on the moving path of the output shaft of the driving member 41. For example, when the driving member 41 is a linear cylinder, the detection unit can be located on the moving path of the piston rod, and the detection unit can be used to detect whether the piston rod is extended or retracted into place, and problems with the cover 12 can also be detected according to the operation of the driving member 41. The specific setting position of the detection unit is not specifically limited in the embodiment of the utility model.

[0058] It should also be noted that when the driving member 41 is a linear cylinder, in order to detect the working state 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 arranged in the rodless cavity or the rod cavity of the linear cylinder to detect the situation of the linear cylinder receiving gas.

[0059] In order to make the purpose, technical solution and beneficial effects of the utility model clearer, the following describes the use process of the battery auxiliary infiltration device 100 provided in the embodiment of the utility model to further describe the utility model. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model.

[0065] Step 106: the pressure detection component detects the pressure in the accommodating chamber, and 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 the above 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 take out the battery 200 .

[0068] The first setting value is greater than the second setting value, the second setting value may be normal pressure, i.e., standard atmospheric pressure, and the first setting value may be 0.5 MPa, so that the air pressure can squeeze the battery 200. Of course, the first setting 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 setting value is not specifically limited in the embodiment of the utility model.

[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 the embodiment of the utility model.

[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 the embodiment of the utility model. In the related art, the time taken to allow the electrolyte to infiltrate the electrode and the diaphragm by leaving the battery 200 to stand still generally takes 8-36 hours. When the battery 200 is infiltrated using the battery auxiliary infiltration device 100 proposed in the present application, it has been tested that if the process of boosting, maintaining pressure, and releasing pressure is repeated twice, the time taken can reach 18 minutes, which can greatly reduce the time consumption.

[0071] In an embodiment of the utility model, 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 by force to produce elastic deformation. 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 internal components of the battery 200, thereby improving the infiltration efficiency of the electrolyte, reducing the time cost of infiltrating the internal components of the battery 200, and improving the production efficiency of the battery 200.

[0072] In addition, an embodiment of the utility model 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 receiving chamber, and the pressure regulating mechanism 20 can adjust the pressure in the receiving chamber. When the battery 200 is accommodated in the receiving chamber and the pressure in the receiving chamber increases, the battery 200 is squeezed by force, and the electrolyte inside the battery 200 is also squeezed. The fluidity of the electrolyte can be enhanced, and the electrolyte can be fully in contact with the components inside the battery 200, thereby improving the infiltration efficiency of the electrolyte; when the pressure in the receiving chamber is reduced, the battery 200 can restore the deformation, and the battery 200 can be taken out of the receiving chamber at this time.

[0074] In addition, in some embodiments, Figure 2 , Figure 3 As shown, 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 and distributed along a first direction X. In a 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 is in contact with 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 arranged 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] In the length direction of the battery 200, the shell 206 has a relative top and bottom, and between the top and the bottom of the shell 206, there are also two relative wide faces and two relative narrow faces. The distribution direction of the two wide faces is the thickness direction of the battery 200, and the distribution direction of the two narrow faces is the width direction of the battery 200. In the embodiment of the present application, the positive electrode sheet 203 and the negative electrode sheet 204 are distributed along the thickness direction of the battery 200, and the first surface 201 and the second surface 202 are distributed along the direction perpendicular to the first direction X, that is, the two narrow faces mentioned above.

[0077] When the battery 200 is placed in the receiving cavity, the first surface 201 or the second surface 202 can be in contact with the bottom of the receiving cavity. The battery 200 is placed in the receiving cavity in a side-standing manner, and the width direction of the battery 200 is parallel to the vertical direction. When the receiving cavity is pressurized, the shell of the battery 200 squeezes the electrolyte inside, and the electrolyte moves upward in the vertical direction, and can contact and infiltrate the pole pieces 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 pole pieces 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 place, avoiding the process of the electrolyte slowly climbing. The electrolyte only needs to enter from the outside of the pole piece to the inside along the thickness direction, changing the original long-distance self-infiltration infiltration from bottom to top into a short-distance infiltration 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, so that the size of the battery 200 can be smaller in the vertical direction, which is convenient 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 side-by-side placement proposed in this application is more convenient for taking the battery 200 than the method of placing the wide side downward.
