[0001] This utility model relates to the field of battery technology, and in particular to a mold for manufacturing solid-state battery cells. Background Technology

[0002] In the research and development of solid-state batteries, it is necessary to prepare square solid-state battery cells for testing and analysis. Currently, square lobed molds are commonly used to produce square solid-state battery cells. The main problems with using lobed molds are cumbersome operation, long cell production time, easy breakage of the cell sides during demolding, and inconsistent cell dimensions due to the gaps between the lobes of the mold, which affects the subsequent testing of the cells. To solve these problems, it is urgent to design a mold for producing solid-state battery cells. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a mold for manufacturing solid-state solar cells, so as to solve the problems existing in the current manufacturing process of square solid-state solar cells and improve the efficiency and quality of solar cell manufacturing.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A mold for manufacturing solid-state battery cells includes: an upper pressure rod, a cavity, and a lower pressure rod arranged sequentially from top to bottom. The lower part of the upper pressure rod is detachably connected to the cavity, and the upper part of the lower pressure rod is detachably connected to the cavity. A cavity is formed between the lower end face of the upper pressure rod, the upper end face of the lower pressure rod, and the inner wall of the cavity. The cavity is used to press the battery cell, and the upper pressure rod is used to push out the pressed battery cell.

[0005] The beneficial effects of this utility model are: the mold is an integrated structure, and the operation is simple and convenient. The connection and disassembly between the parts are convenient, which improves the efficiency of cell production. At the same time, the cavity is of a fixed size, so that the battery cell body with uniform size can be obtained. By adjusting the shape of the cavity in the cavity, the shape of the upper pressure rod and the lower pressure rod that cooperate with the cavity can be adjusted, thereby producing solid battery cells of different shapes, which greatly improves the versatility and applicability of the mold.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, a plurality of threaded adjusting rods are connected through the lower pressure rod. The threaded adjusting rods are inserted into the lower pressure rod from the end of the lower pressure rod away from the cavity, and the end of the threaded adjusting rod closest to the cavity moves to abut against the lower end face of the cavity. A plurality of threaded adjusting rods are also connected through the upper pressure rod. The threaded adjusting rods are inserted into the upper pressure rod from the end of the upper pressure rod away from the cavity, and the end of the threaded adjusting rod closest to the cavity moves to abut against the lower end face of the cavity.

[0008] The beneficial effects of adopting the above-mentioned further solutions are: the lower pressure rod in combination with the threaded adjustment rod can realize a variety of demolding methods; the upper pressure rod in combination with the threaded adjustment rod, as well as the lower pressure rod and the threaded adjustment rod on the lower pressure rod, can realize a variety of demolding methods; when adhesion occurs, the cavity can be easily pushed out by the threaded adjustment rod, preventing the battery cell from sticking to the cavity and ensuring the integrity of the battery cell.

[0009] Furthermore, the cavity is provided with a first groove and a second groove that are interconnected, and the cross-section of the first groove is square.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the square cavity segment serves as the forming space for the solid-state battery cell, and the cylindrical cavity segment acts as a guide when cooperating with the pressure rod.

[0011] Furthermore, the upper pressure rod is provided with an upper pressure rod body and a first punch from top to bottom. The upper pressure rod body and the first punch are arranged coaxially, and the first punch is inserted into the first groove.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the upper pressure rod is connected to the cavity through the first punch whose cross-sectional shape matches the cross-sectional shape of the first groove, so that the first punch can be smoothly inserted into the first groove of the cavity, thus realizing the assembly of the upper pressure rod and the cavity.

[0013] Furthermore, the pressure rod is provided with a second punch, a third punch, and a pressure rod body from top to bottom. The second punch, the third punch, and the pressure rod body are arranged coaxially. The second punch is inserted into the first groove, and the third punch is inserted into the second groove.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the pressure rod is connected to the cavity through a second punch whose cross-sectional shape matches the cross-sectional shape of the first groove and a third punch whose cross-sectional shape matches the second groove, so that the second punch can be smoothly inserted into the first groove of the cavity and the third punch can be smoothly inserted into the second groove, thus realizing the assembly of the pressure rod and the cavity.

[0015] Furthermore, the third punch is provided with the end of the second punch abutting against the end of the second groove near the first groove.

[0016] The beneficial effect of adopting the above-mentioned further solution is that it ensures the accuracy of the position of the lower pressure rod inserted into the cavity. Once the position of the lower pressure rod inserted into the cavity is determined, the solid-state battery cell can be manufactured by operating the upper pressure rod.

[0017] Furthermore, at least one pair of first connecting holes for connecting the threaded adjusting rod are provided through the upper pressure rod body, and the two first connecting holes in the pair are symmetrically arranged about the axis of the upper pressure rod;

[0018] The lower pressure rod body has at least one pair of second connecting holes for connecting the threaded adjusting rod, and the two second connecting holes in the pair are symmetrically arranged about the axis of the lower pressure rod.

[0019] The beneficial effects of adopting the above-mentioned further solution are as follows: By symmetrically arranging first connecting holes on the upper pressure rod body and connecting threaded adjusting rods through the first connecting holes, the force applied by the upper pressure rod to the upper end face of the cavity can be made more uniform; at the same time, multiple first connecting holes can apply force to multiple positions on the upper end face of the cavity, facilitating the demolding of the formed battery cell and thus obtaining a complete battery cell. Similarly, by symmetrically arranging second connecting holes on the lower pressure rod body and connecting threaded adjusting rods through the second connecting holes, the force applied by the lower pressure rod to the lower end face of the cavity can be made more uniform; at the same time, multiple second connecting holes can apply force to multiple positions on the lower end face of the cavity, facilitating the demolding of the formed battery cell and thus obtaining a complete battery cell.

[0020] Furthermore, the threaded adjusting rod is a threaded fastener, and a pair of threaded adjusting rods are symmetrically arranged on the upper pressure rod body and a pair of threaded adjusting rods are symmetrically arranged on the lower pressure rod body.

[0021] The advantages of adopting the above-mentioned further solution are: the threaded fasteners are easy to source, can be reused as threaded adjusting rods, and reduce production costs. When replacement or repair is required, only disassembly and replacement with new threaded fasteners are needed.

[0022] Furthermore, it also includes an extension rod, which is connected to the side of the pressure rod away from the cavity by fasteners.

[0023] The beneficial effect of adopting the above-mentioned further solution is that by passing fasteners through the extension rod and screwing them into the threaded blind hole of the lower pressure rod, the two are connected as a whole to form a lower pressure rod assembly. During demolding, pressure can be applied to the extension rod using a press.

[0024] Furthermore, the cavity is made of stainless steel or ceramic.

[0025] The beneficial effect of adopting the above-mentioned further solutions is that using ceramic materials can greatly reduce the damage caused by uneven demolding force. Attached Figure Description

[0038] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0039] like Figure 1-3As shown, this utility model provides a mold for manufacturing solid-state battery cells, comprising: an upper pressure rod 2, a cavity 3, and a lower pressure rod 5 arranged sequentially from top to bottom. The lower part of the upper pressure rod 2 can be inserted into the cavity 3, and the upper part of the lower pressure rod 5 can be inserted into the cavity 3, so that the lower end face of the upper pressure rod 2, the upper end face of the lower pressure rod 5, and the inner wall of the cavity 3 form a cavity, which is the molding space for the solid-state battery cell. During the manufacturing of a square solid-state battery cell, an appropriate amount of battery powder material is loaded into the cavity, and then the upper pressure rod 2 is inserted into the cavity 3. The mold is placed in a press, and the upper pressure rod 2 is squeezed by the press head to reach the set pressure. After holding the pressure for a period of time, the pressure is released, and the lower pressure rod 5 assembly is removed. Figure 9 As shown, the mold is inverted, and the end face of the cavity 3 is squeezed again by the press head to extrude the formed battery cell 4, thus obtaining a battery cell with a complete shape. In this embodiment, a cavity is formed by the lower end face of the upper pressure rod 2, the upper end face of the lower pressure rod 5, and the inner wall of the cavity 3 to produce a square solid-state battery cell. It can be imagined that the shape of the cavity can be changed to prepare solid-state battery cells of different shapes.

[0040] To prevent the battery material from sticking to the inside of the cavity 3, making it difficult to separate the cavity 3 from the upper pressure rod 2, multiple threaded adjusting rods are respectively connected through the upper pressure rod 2 and the lower pressure rod 5. The threaded adjusting rods on the upper pressure rod 2 are screwed into the upper pressure rod 2 from the end of the upper pressure rod 2 away from the cavity 3. The threaded adjusting rods can move to abut against the upper end face of the cavity 3. When the battery material sticks to the inside of the cavity 3, making it difficult to separate the cavity 3 from the upper pressure rod 2, the threaded adjusting rods can be passed through the upper pressure rod 2, and the cavity 3 can be pushed out by turning the threaded adjusting rods, so that the cavity 3 is separated from the upper pressure rod 2.

[0041] Correspondingly, a threaded adjusting rod is provided on the lower pressure rod 5 and screwed into the lower pressure rod 5 from the end of the lower pressure rod 5 away from the cavity 3. The threaded adjusting rod can move to abut against the lower end face of the cavity 3.

[0042] In this embodiment, the cavity 3 is cylindrical in shape. It is conceivable that the diameter of the cavity 3 should be greater than the distance between the two furthest threaded adjusting rods on the upper pressure rod 2 or lower pressure rod 5, ensuring sufficient space for contact with the threaded adjusting rods on the upper or lower end face of the cavity 3. The cavity 3 can be made of stainless steel, or zirconia ceramic material can be selected, ensuring the long-term stability and reliability of the mold; further limitations are not specified here.

[0043] In the above scheme, the mold is an integrated structure, and the operation is simple and convenient. The connection and disassembly between the components are convenient, which improves the efficiency of cell production. At the same time, the cavity is of a fixed size, so that the battery cell body with uniform size can be obtained. By adjusting the shape of the cavity in the cavity 3, the shape of the upper pressure rod 2 and the lower pressure rod 5 that cooperate with the cavity 3 can be adjusted, thereby producing solid battery cells of different shapes, which greatly improves the versatility and applicability of the mold.

[0044] like Figure 3 , Figure 6 As shown, in the preferred embodiment, the cavity 3 has a first groove and a second groove that are interconnected, that is, the inner cavity of the cavity 3 is divided into two sections. The cross-section of the first groove is square, and this section is a square hollow cavity 3. The second groove is a cylindrical hollow cavity 3. The square cavity section is the forming space of the solid-state battery cell, and the cylindrical cavity section plays a guiding role when it cooperates with the pressure rod 5.

[0045] like Figure 1-4 As shown, the upper pressure rod 2 is provided with an upper pressure rod body and a first punch from top to bottom. The upper pressure rod body and the first punch are an integral structure. The upper pressure rod body is cylindrical, and its diameter is similar to that of the cavity 3, but its size is larger than that of the first punch. In this embodiment, the diameter of the upper pressure rod body is the same as that of the cavity 3. The upper pressure rod body and the first punch are coaxially arranged. The first punch is inserted into the first groove of the cavity 3 from above. Therefore, the cross-section of the first punch matches the cross-sectional shape of the first groove. At the same time, in order to push the battery cell 4 out by the upper pressure rod 2, it is necessary to ensure that the height of the first punch is not less than the height of the first groove on the cavity 3. This ensures that when the battery cell 4 is pushed out of the first groove of the cavity 3 by the upper pressure rod 2, the end face of the battery cell 4 facing away from the upper pressure rod 2 does not exceed the end face of the cavity 3. That is, after the battery cell 4 is pushed out, it is located in the second groove.

[0046] In the above scheme, the upper pressure rod 2 is connected to the cavity 3 by a first punch whose cross-sectional shape matches the cross-sectional shape of the first groove, so that the first punch can be smoothly inserted into the first groove of the cavity 3, thus realizing the assembly of the upper pressure rod 2 and the cavity 3.

[0047] like Figure 2 , Figure 3 , Figure 5As shown, the lower pressure rod 5 is provided with a second punch, a third punch, and a lower pressure rod body arranged sequentially from top to bottom. The second punch, the third punch, and the lower pressure rod body are an integral structure, wherein the lower pressure rod body is cylindrical, and the diameter of the lower pressure rod body is similar to the diameter of the cavity 3 and the upper pressure rod body. The size of the second punch < the size of the third punch < the size of the lower pressure rod body. In this embodiment, the diameter of the lower pressure rod body is set to be the same as the diameter of the cavity 3. The second punch, the third punch, and the lower pressure rod body are arranged coaxially. The second punch is inserted into the first groove of the cavity 3 from below, and the third punch is inserted into the second groove. Therefore, the cross-sectional shape of the second punch matches the cross-sectional shape of the first groove, and the cross-sectional shape of the third punch matches the cross-sectional shape of the second groove. The upper and lower pressure rods and the inner wall of the cavity 3 can be in a clearance fit.

[0048] In the above scheme, the pressure rod 5 is connected to the cavity 3 by a second punch whose cross-sectional shape matches the cross-sectional shape of the first groove and a third punch whose cross-sectional shape matches the cross-sectional shape of the second groove, so that the second punch can be smoothly inserted into the first groove of the cavity 3 and the third punch can be smoothly inserted into the second groove, thus realizing the assembly of the pressure rod 5 and the cavity 3.

[0049] like Figure 3 As shown, in the preferred embodiment, the end of the third punch with the second punch abuts against the end of the second groove near the first groove. After abutting, the lowering rod 5 is blocked from continuing to advance, ensuring the accuracy of the position of the lowering rod 5 inserted into the cavity 3. The position of the lowering rod 5 inserted into the cavity 3 is determined, and then the solid-state battery cell is made by operating the upper pressing rod 2.

[0050] In some feasible embodiments, in order to connect the upper pressure rod 2 with the threaded adjusting rod, at least one pair of first connecting holes for connecting the threaded adjusting rod are provided through the upper pressure rod body, and the two first connecting holes in the pair are symmetrically arranged about the central axis of the upper pressure rod 2. Correspondingly, the first connecting holes are threaded holes.

[0051] In the above scheme, by symmetrically setting the first connecting holes on the upper pressure rod body and connecting the threaded adjustment rod through the first connecting holes, the force applied by the upper pressure rod 2 to the upper end face of the cavity 3 can be made more uniform; at the same time, through multiple first connecting holes, force can be applied to multiple positions on the upper end face of the cavity 3, which facilitates the demolding of the formed battery cell and thus obtains a complete battery cell.

[0052] In some feasible embodiments, in order to connect the pressure rod 5 to the threaded adjusting rod, at least one pair of second connecting holes for connecting the threaded adjusting rod are provided through the pressure rod body, and the two second connecting holes in the pair are symmetrically arranged about the axis of the pressure rod 5. Correspondingly, the second connecting holes are threaded holes.

[0053] In the above scheme, by symmetrically setting second connecting holes on the body of the pressure rod and connecting the threaded adjustment rod through the second connecting holes, the force applied by the pressure rod 5 to the lower end face of the cavity 3 can be made more uniform; at the same time, through multiple second connecting holes, force can be applied to multiple positions on the lower end face of the cavity 3, which facilitates the demolding of the formed battery cell and thus obtains a complete battery cell.

[0054] In some feasible embodiments, the threaded adjusting rod uses a threaded fastener. In this embodiment, the threaded adjusting rod uses a first hexagon socket head cap screw 1. A pair of first hexagon socket head cap screws 1 are symmetrically arranged on the upper pressure rod body, and a pair of first hexagon socket head cap screws 1 are also symmetrically arranged on the lower pressure rod body. That is, two threaded through holes are symmetrically opened on the upper pressure rod body, and the thread hole specifications are the same as those of the first hexagon socket head cap screw 1; two threaded through holes are symmetrically opened on the lower pressure rod body, and the thread hole specifications are the same as those of the first hexagon socket head cap screw 1.

[0055] In the above solution, the hex socket head cap screw is readily available and can be reused as a threaded adjustment rod, reducing production costs. When replacement or repair is needed, simply disassemble and replace it with a new threaded fastener.

[0056] like Figure 1-3 , Figure 7 As shown, in the preferred embodiment, the mold is further provided with an extension rod 7, which is connected to the side of the pressure rod 5 away from the cavity 3 by fasteners. Correspondingly, a countersunk hole is formed at the center of the end face of the end of the pressure rod 5 away from the cavity 3, and a threaded blind hole is also formed at the center of the countersunk hole. This countersunk hole is used for positioning the extension rod 7, so that the extension rod 7 can be connected to the threaded blind hole of the pressure rod 5 by fasteners. The fasteners can be second hexagon socket head cap screws 6, selected as needed. During assembly, the second hexagon socket head cap screws 6 are used to pass through the extension rod 7 and screw into the threaded blind hole of the pressure rod 5 to connect the two into a whole, forming the pressure rod 5 assembly. During demolding, pressure can be applied to the extension rod 7 using a press.

[0057] like Figure 3 As shown, in the preferred embodiment, the extension rod 7 is a hollow cylindrical structure with a second cavity inside. An opening is provided on the side of the extension rod 7 away from the cavity 3, so that the fastener can be tightened through the opening to fix the extension rod 7 to the lower pressure rod 5, which is convenient for the operator to operate.

[0058] The specific usage method of the mold is as follows:

[0059] Example 1:

[0060] like Figure 8-9 As shown, according to Figure 8Assemble the mold, fill it with an appropriate amount of battery powder material, and insert the upper pressure rod 2 into the square hole of the cavity 3, i.e., the cavity; further, place the mold into a press, and use the press head to squeeze the upper pressure rod 2 to reach the set pressure. After holding the pressure for a period of time, release the pressure and remove the lower pressure rod 5 assembly. Figure 9 As shown, the mold is inverted, and the end face of the cavity 3 is squeezed again by the press head to extrude the battery cell 4. Other battery materials can then be stacked as needed to obtain the required solid battery cell.

[0061] In Example 1, cavity 3 is made of stainless steel. In reality, the battery cell is directly demolded after molding. During demolding, the battery cell may be damaged due to uneven stress. In this case, the operation can be carried out according to Example 2. Alternatively, the material of cavity 3 can be changed to zirconium oxide ceramic material, which can greatly reduce the damage caused by uneven stress during demolding.

[0062] Example 2:

[0063] like Figure 8-10 As shown, according to Figure 8 Assemble the mold, fill it with an appropriate amount of battery powder material, and insert the upper pressure rod 2 into the square hole of the cavity 3, i.e., the cavity; further, place the mold into a press, and use the press head to squeeze the upper pressure rod 2 to reach the set pressure. After holding the pressure for a period of time, release the pressure and invert the mold. Figure 10 As shown, pressure is applied to and maintained on the extension rod 7 using the press head; then, the first hex socket head cap screw 1 is turned left and right alternately with a wrench to push the cavity 3 upwards towards the press rod 2 until the battery cell 4 is completely separated from the cavity 3. At this point, the press is depressurized, and the lower press rod 5 assembly is removed. Figure 9 As shown, a complete battery cell is obtained.

[0064] The upper pressure rod 2, in conjunction with the threaded adjustment rod, or the lower pressure rod 5, in conjunction with the threaded adjustment rod, can achieve a variety of demolding methods. When adhesion occurs, the battery cell 4 inside the cavity 3 can be easily pushed out through the threaded adjustment rod to prevent the battery cell 4 from sticking to the cavity 3 and to ensure the integrity of the battery cell.

[0065] Example 3:

[0066] like Figure 9 As shown, after removing the battery cell, if the battery powder material adheres to the inner wall of the cavity 3, making it difficult for the cavity 3 to separate from the upper pressure rod 2, the first internal hexagonal head screw 1 can be screwed into the threaded hole of the upper pressure rod 2, and the cavity 3 can be pushed out by alternately turning the first internal hexagonal head screw 1 left and right with a wrench until the two are completely separated.

[0067] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
