Description

Technical Field

[0001] The present invention relates to the technical field of battery processing equipment, and in particular to a battery formation device and formation equipment. Background Art

[0002] When the battery is charged during the formation process, it will produce harmful gas. By connecting to the negative pressure system, the harmful gas can be discharged out of the battery under the action of negative pressure. Because the harmful gas carries electrolyte vapor, in the related technology, the negative pressure system cannot separate the electrolyte vapor, resulting in the harmful gas being carried out with the airflow during the discharge process, causing electrolyte loss. Summary of the invention

[0003] In view of this, the present invention provides a battery formation device and formation equipment to solve the problem that the electrolyte is simultaneously taken out during the exhaust of the formation process, resulting in electrolyte loss.

[0004] In a first aspect, the present invention provides a battery formation device, comprising:

[0005] The cup body is suitable for containing electrolyte; the cup body is provided with a communication port for communicating with the battery filling hole, and the cup body is provided with an exhaust hole for communicating with an external gas source;

[0006] The filter element is arranged in the cup body and is located between the communication port and the exhaust hole. The surface of the filter element is provided with filter holes. The communication port and the exhaust hole are connected through the filter element.

[0007] A support frame, suitable for fixedly connecting or flexibly connecting the filter element to the cup body;

[0008] The cross-sectional area of ​​the cup body perpendicular to the gas transmission direction is defined as A, the total filtering area of ​​the filter holes on the filter element is defined as B, and the following conditions are satisfied: 10%≤B / A≤90%.

[0009] Beneficial effect: The battery formation device provided by the embodiment of the present invention, by arranging a filter with filter holes in the cup body, and making the connecting port and the exhaust hole connected through the filter, so that the airflow containing electrolyte vapor and atomized electrolyte collides with the filter under the action of inertia and decelerates and converges, so that the filter plays a role in intercepting electrolyte vapor and atomized electrolyte, and under the action of gravity, the converged electrolyte falls back to the cup body, and the gas passes through the filter into the negative pressure pipeline, so as to achieve gas-liquid separation, thereby reducing the loss of electrolyte during formation. In addition, since a certain amount of electrolyte is filled in the cup body, the bubbles of useless gas will cause the liquid surface to disturb when the electrolyte liquid surface in the cup body is extracted, forming tiny small liquid droplets of electrolyte. Due to the existence of the filter of this embodiment, on the one hand, the filter plays a role in intercepting the small liquid droplets of electrolyte, and on the other hand, due to the blocking and deceleration of the filter, the disturbance peak of the electrolyte liquid surface is reduced, thereby increasing the distance between the electrolyte liquid surface and the exhaust hole, thereby reducing the amount of liquid loss caused when the electrolyte is extracted from the cup body. Since the transmission of gas mainly depends on the filter holes, when the cross-sectional area of ​​the cup body is large, the total area of ​​the filter holes can be increased to speed up the gas discharge. However, if the total filter area B is too large, the electrolyte will be discharged together with the useless gas. At the same time, if the total filter area B is too large, the airflow will be too dispersed. By limiting the total filter area B, it is easy to converge the electrolyte and achieve gas-liquid separation. On the contrary, if the total filter area B is too small, it is easy to increase the flow resistance and affect the discharge efficiency of the useless gas.

[0010] In a second aspect, the present invention further provides a formation device, comprising: the battery formation apparatus as described above.

[0011] Since the formation equipment includes a battery formation device and has the same effect as the battery formation device, it will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0018] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] When the battery is charged during the formation process, it will produce harmful gases. By connecting a negative pressure system, the harmful gases can be discharged from the battery under the action of negative pressure, thereby reducing the gas content in the battery.

[0022] Since the useless gas carries electrolyte vapor, in the related art, the negative pressure system cannot separate the electrolyte vapor, resulting in the useless gas being taken out with the airflow during the discharge process, causing electrolyte loss. In addition, since the negative pressure cup of the negative pressure system is filled with a certain amount of electrolyte, the bubbles of the useless gas will cause the liquid surface to be disturbed when they are drawn out of the negative pressure cup, forming tiny droplets of electrolyte. The disturbance wave peak will be closer to the negative pressure cup outlet, making it easy for the small droplets of electrolyte to be taken out of the negative pressure cup by the high-speed airflow, thereby causing electrolyte loss.

[0023] The battery formation device provided by the embodiment of the present invention can intercept electrolyte vapor and small liquid droplets of electrolyte, effectively slow down and suppress the airflow disturbance wave peak, and prevent the disturbance wave peak electrolyte from being carried out with the airflow; and gather the electrolyte vapor and small liquid droplets of electrolyte to achieve gas-liquid separation, thereby reducing the loss of electrolyte during formation.

[0024] Combine the following Figure 1 to Figure 2 , describing an embodiment of the present invention.

[0025] According to an embodiment of the present invention, on the one hand, a battery formation device 1 is provided, comprising:

[0026] The cup body 11 is suitable for containing electrolyte; the cup body is provided with a communication port 14 for communicating with the battery injection hole, and the cup body 11 is provided with an exhaust hole 15 for communicating with an external air source;

[0027] The filter element 13 is disposed in the cup body 11 and is located between the communication port 14 and the exhaust hole 15. The surface of the filter element 13 is provided with filter holes, and the communication port 14 and the exhaust hole 15 are connected via the filter element 13.

[0028] The support frame 12 is suitable for fixedly connecting or flexibly connecting the filter element 13 to the cup body 11;

[0029] The cross-sectional area of ​​the cup body 11 perpendicular to the gas transmission direction is defined as A, the total filtering area of ​​the filter holes on the filter element 13 is defined as B, and the following conditions are satisfied: 10%≤B / A≤90%.

[0030] The cup body 11 is provided with an exhaust hole 15 for communicating with the air source device 2 . The cup body 11 is connected to the air source device 2 via an air source pipeline 21 . The air source device 2 is used for evacuating the inside of the cup body 11 .

[0031] In this embodiment, the connecting port 14 opened at the bottom of the cup body 11 is used to be aligned with the liquid injection hole of the battery 3, and the exhaust hole 15 opened in the upper area of ​​the cup body 11 is used to communicate with the gas source device 2. The negative pressure formed by the gas source device 2 can discharge harmful gas out of the battery 3 and reduce the gas content in the battery.

[0032] In this embodiment, the cup body 11 is a straight cylindrical structure, and the exhaust hole 15 is opened at the top of the cup body 11. As a variation, the exhaust hole 15 can also be opened on the side wall surface of the upper area of ​​the cup body 11.

[0033] When the battery formation device is working, the negative pressure will cause a certain amount of electrolyte to be filled in the cup body 11. The electrolyte vapor and the atomized electrolyte will rise with the airflow.

[0034] In this embodiment, a filter 13 with filter holes is arranged in the cup body 11. The filter 13 is located between the connecting port 14 and the exhaust hole 15, and the connecting port 14 and the exhaust hole 15 are connected through the filter 13, so that the airflow containing electrolyte vapor and atomized electrolyte collides with the filter 13 under the action of inertia and decelerates and converges, so that the filter 13 plays a role in intercepting electrolyte vapor and atomized electrolyte, and under the action of gravity, the converged electrolyte falls back to the cup body 11, and the gas passes through the filter 13 into the negative pressure pipe, thereby realizing gas-liquid separation, and further reducing the loss of electrolyte during formation.

[0035] In addition, since the cup body 11 is filled with a certain amount of electrolyte, the bubbles of useless gas will cause the liquid surface to be disturbed when the electrolyte surface in the cup body 11 is extracted, forming tiny small liquid droplets of electrolyte. Due to the presence of the filter element 13 of this embodiment, on the one hand, the filter element 13 serves to intercept the small liquid droplets of electrolyte, and on the other hand, due to the blocking and deceleration of the filter element 13, the disturbance peak of the electrolyte surface is reduced, thereby increasing the distance between the electrolyte surface and the exhaust hole 15, thereby reducing the amount of liquid loss caused by the electrolyte being extracted from the cup body 11.

[0036] The cross-sectional area of ​​the cup body 11 perpendicular to the gas transmission direction is defined as A, and the total filtering area of ​​the filter holes on the filter element 13 is defined as B. The gas transmission direction may be the direction from the exhaust hole 15 to the connecting port 14, specifically, the vertical direction of the cup body 11. If the cross-sectional area of ​​the cup body 11 perpendicular to the gas transmission direction is different, the cross-sectional area here refers to the largest area among the multiple areas. The total filtering area of ​​the filter holes refers to the product of the area of ​​a single filter hole and the number of filter holes.

[0037] Since the transmission of gas mainly depends on the filter holes, when the cross-sectional area of ​​the cup body is large, the total area of ​​the filter holes can be increased to speed up the gas discharge. However, if the total filter area B is too large, the electrolyte will be discharged together with the useless gas. At the same time, if the total filter area B is too large, the airflow will be too dispersed. By limiting the total filter area B, it is easy to converge the electrolyte and achieve gas-liquid separation. On the contrary, if the total filter area B is too small, it is easy to increase the flow resistance and affect the discharge efficiency of the useless gas.

[0038] In some embodiments, the ratio of the total filtering area B of the filter holes on the filter element 13 to the cross-sectional area A of the cup body 11 perpendicular to the gas transmission direction satisfies: B / A≥60%; the pore size of the filter holes is C, which satisfies: C≤0.5mm.

[0039] When the value of B / A is large, if the aperture of the filter hole is set relatively large, the filter element 13 is easy to deform when the cup body 11 is evacuated. After deformation and rupture, the interception effect of electrolyte vapor and small liquid droplets of electrolyte will become poor, which may easily cause the outflow of electrolyte. Therefore, the aperture C of the filter hole should be made smaller. In this embodiment, C≤0.5mm.

[0040] In this embodiment, the pore size C of the filter hole can be 0.1 mm, 0.15 mm, 0.2 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.5 mm, etc.

[0041] In some embodiments, the pore spacing between adjacent filter holes is D, satisfying: B / A≤40%, D≥0.2 mm.

[0042] When the value of B / A is small, the total filtering area of ​​the filter element 13 is relatively small, and the hole spacing D between adjacent filter holes should be made larger to avoid gas concentration in the filter holes and affect the filtering efficiency.

[0043] Since the filter element 13 needs to work under vacuum negative pressure, in order to ensure that the filter element 13 does not deform, it is necessary to make certain requirements on the hardness of the filter element 13 to meet the use requirements and avoid frequent damage and replacement.

[0044] In some embodiments, the filter element 13 has a plurality of filter layers stacked together, and the filter holes of two adjacent filter layers are not overlapped.

[0045] The filter element 13 includes a plurality of stacked filter layers, and the filter holes of two adjacent filter layers are not overlapped, which can extend the airflow path and thus slow down the airflow speed; at the same time, it can increase the probability of the airflow containing electrolyte vapor and atomized electrolyte colliding with the filter element 13 under the action of inertia, thereby improving the recovery rate of the electrolyte.

[0046] In this embodiment, each filter layer is cylindrical in shape. After multiple filter layers are stacked, the filter element 13 can still be cylindrical in shape and can be installed through the support frame 12 to adapt to cup bodies 11 of different shapes.

[0047] In some embodiments, the pore size of the filter pores of the filter layer close to the communication port 14 is larger than the pore size of the filter pores of the filter layer away from the communication port 14 .

[0048] In this embodiment, when the cup body 11 is placed vertically, the filter layer on the side close to the communication opening 14 is arranged relatively below the filter layer on the side away from the communication opening 14 .

[0049] Due to the crystallization of the electrolyte, the electrolyte converges downward under the action of gravity. As the electrolyte of the upper filter layer drips to the lower filter layer, the electrolyte of the lower filter layer will remain for a long time. In order to prevent the filter holes of the filter layer from being blocked by electrolyte crystals, when setting the filter holes, the pore size of the filter holes of the filter layer close to the communication port 14 is made larger, which can prevent the electrolyte crystals from blocking the holes.

[0050] In some embodiments, along the airflow direction from the communication port 14 toward the exhaust hole 15 , the pore sizes of the filter holes of the plurality of stacked filter layers gradually decrease.

[0051] Due to the crystallization of the electrolyte, the electrolyte gathers downward under the action of gravity. At this time, the filter layer located below may have the problem of the filter holes being blocked by the electrolyte crystals. Therefore, when setting the filter holes, the airflow direction along the connecting port 14 toward the exhaust hole 15 is made so that the pore size of the filter holes of the multiple stacked filter layers gradually decreases, that is, the filter holes of the filter layer located below are larger, thereby avoiding the holes being blocked by the electrolyte crystals and improving the overall effective utilization rate of the filter element 13.

[0052] In some embodiments, the projections of the filter holes of two adjacent filter layers do not overlap.

[0053] By making the projections of the filter holes of two adjacent filter layers not overlap, the airflow containing electrolyte vapor and atomized electrolyte cannot directly pass through the filter element 13 along a straight line, thereby increasing the airflow path and having the effect of slowing down the airflow speed. In addition, the probability of the airflow containing electrolyte vapor and atomized electrolyte colliding with the filter element 13 under the action of inertia is increased, thereby improving the recovery rate of the electrolyte.

[0054] In some embodiments, the vertical distance between the filter element 13 and the connecting port 14 is h1, and the vertical distance between the filter element 13 and the exhaust hole 15 is h2, which satisfies: 30%≤h2 / h1≤70%.

[0055] Combination Figure 2 As shown, the vertical distance between the filter element 13 and the connecting port 14 refers to the vertical distance between the opening end surface of the connecting port 14 located on the side of the cup body 11 close to the filter element 13 and the filter element 13; the vertical distance between the filter element 13 and the exhaust hole 15 refers to the vertical distance between the opening end surface of the exhaust hole 15 located on the side of the cup body 11 close to the filter element 13 and the filter element 13.

[0056] By limiting the range of the ratio h2 / h1, it can be ensured that the gas has a sufficient transmission distance between the filter element 13 and the connecting port 14 to separate the electrolyte and improve the recovery rate of the electrolyte.

[0057] In some embodiments, the communication port 14 is disposed at the bottom of the cup body 11 , and the exhaust hole 15 is disposed at the top of the cup body 11 ;

[0058] Along the airflow direction from the communication port 14 to the exhaust hole 15 , the communication port 14 , the exhaust hole 15 and the filter element 13 partially overlap.

[0059] Along the airflow direction from the connecting port 14 toward the exhaust hole 15, by making the connecting port 14, the exhaust hole 15 and the filter element 13 partially overlap, it can ensure that the connecting port 14 and the exhaust hole 15 are straight in the airflow path, avoiding too many turns in the airflow path, and quickly drawing a vacuum to speed up the discharge of harmful gases.

[0060] In some embodiments, the material of the filter element 13 includes: any one of PP, PVDF, PTFE or steel.

[0061] In some embodiments, in combination Figure 2 As shown, one end of the support frame 12 connected to the cup body 11 faces one end of the support frame 12 connected to the filter element 13; the support frame 12 is tilted downward along the direction of gravity.

[0062] In this embodiment, the support frame 12 is funnel-shaped or cone-shaped. By tilting the support frame 12 downward along the direction of gravity, it is beneficial to the condensation of electrolyte vapor and small droplets of electrolyte, and they fall back into the cup body 11 by gravity, thereby improving the recovery efficiency and avoiding a large amount of electrolyte from being retained on the support frame 12.

[0063] In some embodiments, at least a portion of the filter element 13 is recessed toward the side facing downward in the direction of gravity.

[0064] In this embodiment, the filter element 13 may be cambered or conical. By setting at least a portion of the filter element 13 to be concave toward the side facing downward in the direction of gravity, it is beneficial for the condensation of electrolyte vapor and small droplets of electrolyte to fall back into the cup body 11 by gravity, thereby improving the recovery efficiency and preventing the electrolyte from clogging the filter holes of the filter element 13.

[0065] In some embodiments, the integral structure formed by the support frame 12 and the filter element 13 is used as a boundary layer; the volume of the space inside the cup body 11 and located relatively above the boundary layer is defined as V1, and the volume of the space inside the cup body 11 and located relatively below the boundary layer is defined as V2, satisfying: 5%≤V1 / V2≤30%.

[0066] By limiting the lower limit of the ratio of the volume of the space above the boundary layer to the volume of the space below the boundary layer, it is possible to avoid material waste caused by the volume V2 of the space below the boundary layer being too large. By limiting the upper limit of the ratio of the volume of the space above the boundary layer to the volume of the space below the boundary layer, it is possible to avoid the volume V2 of the space below the boundary layer being too small, thereby ensuring that sufficient liquid storage space is retained in the lower portion of the cup body 11.

[0067] In some embodiments, the support frame 12 and the cup body 11 are integrally formed or welded.

[0068] Since the battery formation device of this embodiment needs to work under vacuum negative pressure, the integrity of the support frame 12 and the cup body 11 can be ensured by adopting one-piece molding or welding connection, the firmness of the support frame 12 can be ensured, and compression deformation can be avoided.

[0069] In some other embodiments, the support frame 12 is detachably disposed relative to the cup body 11 .

[0070] The detachable arrangement of the support frame 12 and the cup body 11 does not include a welding connection.

[0071] The support frame 12 is suitable for being movably arranged along the extending direction of the cup body 11 to adjust the distance between the filter element 13 and the exhaust hole 15 in the extending direction of the cup body 11 .

[0072] The cup body 11 can be provided with a slide rail. By making the support frame 12 slide and cooperate with the slide rail of the cup body 11, the support frame 12 can be movably adjusted, and then the distance between the filter element 13 and the exhaust hole 15 in the extension direction of the cup body 11 can be adjusted, so that the filter element 13 can be positioned according to the electrolyte level in the cup body 11, ensuring that the disturbance peak of the electrolyte level is reduced, thereby reducing the amount of liquid loss caused by the electrolyte being extracted from the cup body 11.

[0073] According to an embodiment of the present invention, on the other hand, a formation device is provided, including: the battery formation device 1 as described above.

[0074] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
