[0043] Hereinafter, some embodiments of the disclosed technology will be described in detail with reference to the accompanying drawings.

[0044] At present, commercial secondary batteries include nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries and lithium secondary batteries. Among these secondary batteries, lithium secondary batteries have the advantages of low self-discharge rate, high energy density, small memory effect and free charge and discharge.

[0045] In some embodiments, when manufacturing secondary batteries, the secondary batteries are accommodated in a tray customized according to the shape of each secondary battery, and the tray containing the secondary batteries is transferred to each process for a manufacturing process, a testing process, etc. However, the disclosed technology can be implemented in some embodiments to provide a tray that can accommodate secondary batteries of various types or sizes.

[0046] In one aspect of the disclosed technology, a battery storage tray 10 can be provided that can accommodate various types (e.g., multiple models) or sizes of battery cells 300. In another aspect of the disclosed technology, a battery storage tray 10 can be provided that can implement an area for accommodating battery cells 300 through a convenient assembly method (see Figure 8 ).

[0047] The battery storage tray 10 based on one aspect of the disclosed technology can be mainly used for the activation process in the process of manufacturing the battery cell 300. In one example, the activation process can be a process of activating the battery cell by applying a low current to inject charge so that the original lithium-ion battery raw material is transformed from an inactive state to an activated state after performing the electrode process and the assembly process, so that the activated battery cell becomes stable, and the active electrochemical system is in an operable state, thereby performing a charging operation by converting electrical energy into chemical energy stored in the cell and performing a discharge operation by converting the stored chemical energy into electrical energy. In some embodiments, the activation process undergoes a formation process, an aging process, and a performance test process, and may include a degassing process if necessary. In some embodiments, the battery storage tray 10 can be used for the entire activation process. However, the use of the battery storage tray 10 is not limited to the activation process, and the battery storage tray 10 can also be used for other processes or conditions.

[0048] Figure 1 1 is a perspective view schematically showing a battery storage tray 10 according to an embodiment of the disclosed technology. In some embodiments, the battery cells 300 are accommodated in the battery storage tray 10 (see Figure 8 ).

[0049] Reference Figure 1 , a battery storage tray 10 based on one aspect of the disclosed technology may include a receiving portion 100. In some embodiments, the battery storage tray 10 may include an insert 200. In some embodiments, the battery storage tray 10 may include a receiving portion 100 and an insert 200 embedded in the receiving portion 100. The insert 200 may be embedded in the receiving portion 100, and may be coupled and fixed to a portion of the receiving portion 100 while being embedded. The insert 200 may be coupled and fixed to a portion of the receiving portion 100, or may be disconnected and separated from a portion of the receiving portion 100. Details thereof will be described below.

[0050] Figure 2 1 is a perspective view schematically showing a receiving portion 100 of a battery storage tray 10 according to one embodiment of the disclosed technology. Figure 3 is a perspective view schematically showing a portion of a receiving portion 100 of a battery storage tray 10 according to an embodiment of the disclosed technology, and is Figure 2 Magnified view of area A. Figure 4 A portion of a receiving portion 100 of a battery storage tray 10 according to an embodiment of the disclosed technology is schematically shown. Specifically, Figure 4 yes Figure 2 XY plane diagram of area A. Figure 5The receiving portion 100 of the battery storage tray 10 according to one embodiment of the disclosed technology is schematically shown. Specifically, Figure 5 yes Figure 2 XY plane diagram. Figures 2 to 5 The receiving portion 100 based on one aspect of the disclosed technology is described in detail.

[0051] The receiving portion 100 based on one aspect of the disclosed technology may include a plastic material. The structure of the receiving portion 100 may be appropriately designed in consideration of the insert 200 to be embedded and the battery cell 300 to be accommodated. In some embodiments, the structure of components such as the first coupling portion 110 (described below) of the receiving portion 100 may also be appropriately designed. With this design, the receiving portion 100 may be implemented by injection molding or the like.

[0052] Reference Figure 2 , the receiving portion 100 according to one aspect of the disclosed technology may include an inner space 100 a in which the insert 200 is embedded and one or more first coupling portions 110 disposed in the inner space 100 a .

[0053] The receiving portion 100 according to one aspect of the disclosed technology may have a polyhedral shape with one surface open. Figure 2 , the receiving portion 100 may have a hexahedral shape with one surface open. In some embodiments, the receiving portion 100 based on another aspect of the disclosed technology may have a polyhedral shape with multiple surfaces open. In some embodiments, the receiving portion 100 based on another aspect of the disclosed technology may have a polyhedral shape with one surface open and another surface different from the one surface at least partially open. For example, one terminal 340 of the bidirectional battery cell 300 described below may protrude outward through the one open surface, and the other terminal 340 may protrude outward through the open portion of another surface that is at least partially open. In another example, the other surface may be partially and / or partially open to allow the terminal 340 to protrude outward. However, these are merely examples, and the receiving portion 100 can be designed into a variety of different shapes as needed, as long as the terminal 340 can properly protrude outward and easily contact with the probe used in the formation or test.

[0054] The receiving portion 100 based on one aspect of the disclosed technology may have an open surface for embedding the insert 200 therein as described above, and may include an internal space 100a formed by being surrounded by a surface other than the open surface. That is, the internal space 100a may be a space formed by being surrounded by a surface of the receiving portion 100 other than the open surface for embedding the insert 200. Therefore, the insert 200 may be embedded in the internal space 100a. In some embodiments, as described above, the receiving portion 100 may include an open surface and another surface partially open to allow the terminal 340 to protrude outward.

[0055] In some embodiments, reference Figure 2 The receiving portion 100 may include an outer wall 100b for protecting the insert 200 embedded therein from external influences. The outer wall 100b may be an important component for forming the above-mentioned inner space 100a.

[0056] The receiving portion 100 according to one aspect of the disclosed technology may fix the insert 200 embedded therein, and may include one or more first coupling portions 110 disposed in the inner space 100a for fixing the insert 200 in the receiving portion 100. The insert 200 may be embedded and fixed in the inner space 100a of the receiving portion 100 while being coupled to the first coupling portions 110.

[0057] In some embodiments, in the receiving portion 100 based on one aspect of the disclosed technology, the first coupling portion 110 may include a plurality of auxiliary coupling portions 111. The number of the auxiliary coupling portions 111 is not particularly limited as long as the number is plural, but may be determined according to the shape or size of the second coupling portion 220 of the insert 200 to be described below. Figure 2 In the embodiment, the number of the auxiliary coupling portions 111 of a specific (one) first coupling portion 110 may be four.

[0058] In some embodiments, the first coupling portion 110 may include a plurality of auxiliary coupling portions 111, and the plurality of auxiliary coupling portions 111 may be arranged to be continuous. Here, in some embodiments, the term "continuous" may be used to indicate that there are no other components between the auxiliary coupling portions 111. That is, the portion where the auxiliary coupling portions 111 are continuously arranged may be referred to as the first coupling portion 110.

[0059] Reference Figure 2, the receiving portion 100 may include a plurality of first coupling portions 110, and may optionally include a side wall 120 configured to partition between adjacent first coupling portions 110. When the receiving portion 100 includes a plurality of first coupling portions 110, the gap between adjacent first coupling portions 110 may be appropriately designed in consideration of the insert 200 to be embedded and the battery cell 300 to be accommodated. In some embodiments, when the receiving portion 100 includes the side wall 120, the size (size is a term covering width, length, and height), shape, position of the side wall 120, and the gap between the side wall 120 and the adjacent first coupling portion 110 may also be appropriately designed in consideration of the insert 200 to be embedded and the battery cell 300 to be accommodated.

[0060] In some embodiments, the accommodating portion 100 based on one aspect of the disclosed technology may include a plurality of first coupling portions 110 as described above. Each of the first coupling portions 110 may independently include a plurality of auxiliary coupling portions 111, and here, each of the first coupling portions 110 may independently include a different number of auxiliary coupling portions 111. For example, one first coupling portion 110 may include four auxiliary coupling portions 111, while another first coupling portion 110 may include seven auxiliary coupling portions 111.

[0061] Based on one aspect of the disclosed technology, the number of first connecting portions 110 in the accommodating portion 100 and the number of auxiliary connecting portions 111 included in each of the first connecting portions 110 are determined based on the size and number of the insert 200 and the battery cells 300 to be accommodated (which will be described below), and are therefore not particularly limited to a specific range.

[0062] Reference Figure 2 , the auxiliary coupling parts 111 may be arranged in parallel along one direction. Figure 2 In the area marked as "A", the first coupling portion 110 may include a plurality of auxiliary coupling portions 111, and the auxiliary coupling portions 111 may be arranged in parallel along the Y-axis direction. That is, all the auxiliary coupling portions 111 included in one first coupling portion 110 may be arranged in parallel along one direction.

[0063] In some embodiments, the auxiliary connection portion 111 based on one aspect of the disclosed technology can have the same or different width, length, and height. That is, the dimensions (dimensions are terms covering width, length, and height) of the auxiliary connection portion 111 can be independent of each other. Here, the width can be the gap between the two ends in the X-axis direction. In some embodiments, the length can be the gap between the two ends in the Y-axis direction. In some embodiments, the height can be the gap between the two ends in the Z-axis direction (see Figure 3 ).

[0064] Reference Figure 3 , the width, length, and height H of the auxiliary connection part 111 may be the same or different from each other. Based on one aspect of the disclosed technology, the auxiliary connection parts 111 of the first connection part 110 may all have the same height. Here, "same" may mean approximately the same, and may mean both a situation where the values ​​are exactly the same, and a situation where the values ​​are different and the difference between the values ​​is within 10%. In some embodiments, the height H may be the distance from the lowest position to the highest position in the Z-axis direction. When the height H of the auxiliary connection parts 111 is the same, when the insert 200 is embedded in the accommodating part 100, a higher connection stability can be ensured.

[0065] In some embodiments, the width, length, and height of the auxiliary coupling portion 111 may be determined based on the shape or size of the second coupling portion 220 of the insert 200, which will be described below. Specifically, the height H of the auxiliary coupling portion 111 may be at least 5% or 10% of the height of the receiving portion 100 to ensure the connection stability with the insert 200. The height of the receiving portion 100 may be the distance from the lowest position to the highest position in the receiving portion 100 in the Z-axis direction.

[0066] In the auxiliary coupling portion 111 according to one aspect of the disclosed technology, a predetermined gap d1 may exist between adjacent auxiliary coupling portions 111. Figure 3 and Figure 4 , there may be a plurality of auxiliary coupling portions 111 in the first coupling portion 110, and a predetermined gap d1 may exist between the auxiliary coupling portions 111 adjacent to each other. In some embodiments, the gaps d1 between different pairs of adjacent auxiliary coupling portions 111 may be different from or the same as each other. In some embodiments, the size of the gap d1 may be determined based on the shape or size of the second coupling portion 220 of the insert 200 to be described below. When there is a predetermined gap d1 between adjacent auxiliary coupling portions 111, a battery storage tray 10 that can accommodate battery cells 300 of various types (e.g., multiple models) or sizes and allows the area for accommodating the battery cells 300 to be implemented by a convenient assembly method can be provided.

[0067] Reference Figure 3 , the first coupling portion 110 of the battery storage tray 10 according to one aspect of the disclosed technology may be provided to protrude from a surface 100a-1 of the internal space 100a. Figure 2 and Figure 3, the first coupling portion 110 may be disposed on a surface 100a-1 in the internal space 100a. In some embodiments, the first coupling portion 110 may be disposed on a surface 100a-1 and may be configured to protrude from a surface 100a-1 along the positive Z-axis direction. Here, the positive Z-axis direction may be the direction indicated by the Z-axis arrow shown in the figure. The protruding shape may be implemented by injection molding or the like.

[0068] In some embodiments, reference Figure 3 In the first coupling portion 110 of the battery storage tray 10 according to one aspect of the disclosed technology, the auxiliary coupling portion 111 may be provided to protrude from one surface 100a-1 in the inner space 100a. Figure 2 and Figure 3 , the auxiliary coupling portion 111 may be disposed on one surface 100a-1 in the internal space 100a. In some embodiments, the auxiliary coupling portion 111 may be disposed on one surface 100a-1 and may be disposed to protrude from one surface 100a-1 in the positive Z-axis direction.

[0069] In some embodiments, the receiving portion 100 of the battery storage tray 10 based on one aspect of the disclosed technology may further include other surfaces 100a-c in addition to the one surface 100a-1 provided with the first coupling portion 110. In the disclosed technology, the other surfaces 100a-c of the internal space 100a may be other surfaces of the internal space 100a except the one surface 100a-1. Figure 2 , the receiving portion 100 may include four other surfaces 100 a - c surrounding the one surface 100 a - 1 on which the first coupling portion 110 is disposed.

[0070] In some embodiments, the first coupling portion 110 of the battery storage tray 10 according to one aspect of the disclosed technology may be arranged to face at least some of the other surfaces 100a-c of the interior space 100a. Figure 2 , any first coupling portion 110 may be disposed on one surface 100a-1 of the internal space 100a while being disposed to face two of the four other surfaces 100a-c. Figure 2 , the first coupling portion 110 in the region A may be disposed on one surface 100a-1 of the inner space 100a while being disposed to face two other surfaces 100a-c parallel to the Y-axis direction.

[0071] In some embodiments, in the first coupling portion 110 of the battery storage tray 10 based on one aspect of the disclosed technology, the auxiliary coupling portion 111 may be arranged to face at least some of the other surfaces 100a-c of the above-mentioned internal space 100a. The auxiliary coupling portions 111 of the first coupling portion 110 may be arranged in parallel along one direction as described above, and the arrangement direction may be a direction facing the other surfaces 100a-c. That is, the auxiliary coupling portions 111 may be arranged in parallel along the Y-axis direction, and the auxiliary coupling portions 111 may be arranged to face the other surfaces 100a-c parallel to the Y-axis direction.

[0072] Reference Figure 2 , the first coupling portion 110 of the battery storage tray 10 according to one aspect of the disclosed technology may not contact other surfaces 100a-c in the interior space 100a. Figure 2 , in the first coupling portion 110 of the battery storage tray 10 based on one aspect of the disclosed technology, the auxiliary coupling portion 111 may not contact other surfaces 100a - c in the inner space 100a .

[0073] Reference Figure 2 The first coupling portion 110 of the battery storage tray 10 according to one aspect of the disclosed technology may be arranged to have a predetermined gap d2 with other adjacent surfaces 100a-c. Here, the other adjacent surfaces 100a-c may be other surfaces 100a-c that are closest to the first coupling portion 110 disposed on one surface 100a-1 of the internal space 100a and face the first coupling portion 110.

[0074] In some embodiments, reference Figure 2 , the auxiliary coupling portion 111 of the first coupling portion 110 may be provided to have a predetermined gap d2 with the other adjacent surfaces 100a-c. In some embodiments, the size of the gap d2 may be determined based on the shape or size of the second coupling portion 220 of the insert 200 to be described below. When there is a predetermined gap d2 between the first coupling portion 110 and the other adjacent surfaces 100a-c, a battery storage tray 10 that can accommodate battery cells 300 of various types (e.g., multiple models) or sizes and allows the area for accommodating the battery cells 300 to be implemented by a convenient assembly method may be provided.

[0075] In some embodiments, the first coupling portion 110 based on one aspect of the disclosed technology can be disposed on a surface 100a-1 in the internal space 100a, and the surface 100a-1 can include one or more edges 100a-1E. Due to the presence of the edge 100a-1E, a closed area can be formed, and the first coupling portion 110 can be disposed in the closed area. In some embodiments, the edge 100a-1E can represent the boundary of the surface 100a-1 itself, or represent the boundary line between the surface 100a-1 and other surfaces 100a-c.

[0076] In some embodiments, the edge 100a-1E may be a straight line or a curved line. When the edge 100a-1E is a straight line, the number of edges 100a-1E may be calculated based on whether the direction and position of the straight line are different, and when the edge 100a-1E is a curved line, the number of edges 100a-1E may be calculated based on whether the curvature and position of the curved line are different. Here, when any one edge 100a-1E should be moved to overlap with another edge 100a-1E in the same coordinate system, the positions may be described as being different from each other. For example, referring to Figure 5 , a surface 100 a - 1 of the receiving portion 100 has four straight lines with different directions and positions, and thus can be described as including four straight edges 100 a - 1E.

[0077] In the receiving portion 100 according to one aspect of the disclosed technology, one or more first coupling portions 110 may be disposed along each edge 100a-1E. Here, disposed along the edge 100a-1E means disposed parallel to the edge 100a-1E.

[0078] In some embodiments, a surface 100a-1 based on an aspect of the disclosed technology may include a plurality of edges 100a-1E. In some embodiments, a surface 100a-1 may include one or more pairs of edges 100a-1E facing each other.

[0079] Reference Figure 5 , a surface 100a-1 includes two x edges 100a-1Ex parallel to the X axis and two y edges 100a-1Ey parallel to the Y axis. That is, referring to Figure 5 , a surface 100a-1 includes two pairs of edges 100a-1E facing each other, including a total of four straight edges 100a-1E. In some embodiments, referring to Figure 5 , seven first coupling portions 110 are disposed along each x-edge 100a-1Ex, and five first coupling portions 110 are disposed along each y-edge 100a-1Ey.

[0080] Reference Figure 5, the number and position of the first coupling portions 110 provided along the edges 100a-1E facing each other may correspond to each other. That is, the number and position of the first coupling portions 110 provided along one x edge 100a-1Ex may correspond to the number and position of the first coupling portions 110 provided along another x edge 100a-1Ex facing the one x edge 100a-1Ex. Here, "corresponding" may mean that the number of first coupling portions 110 is the same and the positions are symmetrical. When the number and positions of the first coupling portions 110 provided along the edges 100a-1E facing each other correspond to each other in this way, it may be advantageous to implement the area for accommodating the battery cells 300 by a convenient assembly method. However, this is merely an example, and the number and position of the first coupling portions 110 may vary based on the design.

[0081] Reference Figure 4 , the first coupling portion 110 based on one aspect of the disclosed technology may be disposed on one surface 100a-1 in the internal space 100a, and may be disposed to have a predetermined gap d3 with an edge 100a-1E of an adjacent one surface 100a-1. Here, the adjacent edge 100a-1E may be the edge 100a-1E that is closest to the first coupling portion 110 and faces the first coupling portion 110. In some embodiments, the size of the gap d3 may be determined based on the shape or size of the second coupling portion 220 of the insert 200 to be described below.

[0082] When the edge 100a-1E represents the boundary line between a surface 100a-1 and other adjacent surfaces 100a-c, the predetermined gap d2 between the first connecting portion 110 and other adjacent surfaces 100a-c and the predetermined gap d3 between the first connecting portion 110 and the adjacent edge 100a-1E may be the same.

[0083] When a predetermined gap d3 exists between the first coupling portion 110 and the adjacent edge 100a-1E, a battery storage tray 10 capable of accommodating various types (eg, multiple models) or sizes of battery cells 300 and allowing an area for accommodating battery cells 300 to be implemented through a convenient assembly method can be provided.

[0084] Specifically, refer to Figure 4 The auxiliary coupling portion 111 according to one aspect of the disclosed technology may be disposed on one surface 100a-1 in the inner space 100a, and may be disposed to have a predetermined gap d3 with an edge 100a-1E of the adjacent one surface 100a-1.

[0085] In the disclosed technology, as described above, the sizes of the gaps d1, d2, and d3 can be determined based on the shape or size of the second coupling portion 220 of the insert 200 described below. In some embodiments, when the representative values ​​of the gaps d1, d2, and d3 are not constant due to changes in the measurement position or the measurement object, these values ​​may represent average values. For example, referring to Figure 4 , a plurality of auxiliary coupling parts 111 may be provided, and the gap d3 between the auxiliary coupling part 111 and the adjacent edge 100a-1E may be the same or different for each auxiliary coupling part 111. When the gap d3 between each auxiliary coupling part 111 and the adjacent edge 100a-1E is the same, its size may be used as a representative value of the gap d3, and when the gap d3 between the auxiliary coupling part 111 and the adjacent edge 100a-1E is different in one or more auxiliary coupling parts 111, the size of the arithmetic mean of the gap d3 may be used as a representative value of the gap d3.

Figure 7 is a perspective view schematically showing a portion of an insert 200 of a battery storage tray 10 according to an embodiment of the disclosed technology. Specifically, Figure 7 yes Figure 6 Magnified view of area B.

[0087] According to one aspect of the disclosed technology, the battery cell 300 can be accommodated in the insert 200 of the battery storage tray 10. In the battery storage tray 10, the insert 200 can be coupled to the receiving portion 100 to form an area for accommodating the battery cell 300, and the battery cell 300 can be accommodated in the area for accommodating the battery cell 300 (the battery storage portion 260 to be described below, see Figure 8 The battery storage tray 10 accommodating the battery cells 300 may be mainly used in an activation process and the like.

[0088] The insert 200 based on one aspect of the disclosed technology may include a plastic material. The structure of the insert 200 may be appropriately designed in consideration of the type or size of the battery cell 300 to be accommodated. In some embodiments, the structure of the second coupling portion 220 (described below) and other components of the insert 200 may also be appropriately designed. With this design, the insert 200 may be implemented by injection molding or the like.

[0089] The insert 200 according to one aspect of the disclosed technology may include a storage slot 210. The storage slot 210 may be a slot for accommodating at least a portion of each battery cell 300. In some embodiments, when a plurality of inserts 200 are arranged and combined, the storage slot 210 may allow the battery storage tray 10 to have a battery storage portion 260 (see FIG. 1 ) for accommodating the battery cells 300. Figure 8 ).

[0090] In some embodiments, the insert 200 based on one aspect of the disclosed technology may include a second coupling portion 220 that may be coupled to the first coupling portion 110 included in the receiving portion 100. That is, when the insert 200 is embedded in the receiving portion 100, the first coupling portion 110 and the second coupling portion 220 may be coupled, and the insert 200 may be fixed to the inner space 100a of the receiving portion 100. Conversely, the first coupling portion 110 and the second coupling portion 220 coupled to each other may be disconnected, and since the first coupling portion 110 and the second coupling portion 220 are disconnected, the receiving portion 100 and the insert 200 may be separated.

[0091] In some embodiments, the insert 200 based on one aspect of the disclosed technology may include a second coupling portion 220 configured to be coupled to one or more auxiliary coupling portions 111 selected from a plurality of auxiliary coupling portions 111 included in a first coupling portion 110. That is, a first coupling portion 110 may include a plurality of auxiliary coupling portions 111 as described above (see Figures 2 to 5 ), and the second coupling portion 220 of the insert 200 may be coupled to one or more of the plurality of auxiliary coupling portions 111. When the second coupling portion 220 is coupled to one or more of the plurality of auxiliary coupling portions 111, the insert 200 may be coupled and fixed to the receiving portion 100. Details of the coupling between the first coupling portion 110 of the receiving portion 100 and the second coupling portion 220 of the insert 200 will be described below.

[0092] The insert 200 according to one aspect of the disclosed technology may include a support body 230 having a second coupling portion 220. The second coupling portion 220 may be disposed at an appropriate position on the support body 230 so as to utilize space when the insert 200 is coupled to the receiving portion 100 and the battery cell 300 is received. In some embodiments, the insert 200 may include a plurality of second coupling portions 220 to stably couple with the receiving portion 100.

[0093] Reference Figure 6, the insert 200 according to one aspect of the disclosed technology may include a support body 230 provided with second coupling portions 220 at both ends. The support body 230 is a component for supporting each component of the insert 200, and may have a shape that is long in the longitudinal direction, for example, may have a beam or a tube shape, but is not limited thereto. That is, referring to Figure 6 , in the support body 230 having a shape that is long in the longitudinal direction along the Y-axis, the second coupling parts 220 may be located at both ends along the Y-axis.

[0094] In some embodiments, the second coupling portion 220 may be integrally formed with the support body 230 and may be joined and coupled thereto by welding, bonding, or hardware (bolts, etc.). Preferably, when the structure of the insert 200 is implemented by injection molding or the like, the second coupling portion 220 and the support body 230 may be integrally formed.

[0095] The insert 200 according to one aspect of the disclosed technology may include a plurality of storage frame portions 240 disposed on a support body 230 and including a bending member 250 that is at least partially bent. Figure 6 , a plurality of at least partially curved curved members 250 may be disposed on the support body 230, and in this way, the insert 200 may also include a plurality of storage frame portions 240 including the curved members 250. Specifically, referring to Figure 6 , the bending member 250 may protrude from one surface of the support body 230 .

[0096] In some embodiments, the bending member 250 can be integrally formed with the support body 230 and can be joined and coupled thereto by welding, bonding, or hardware (bolts, etc.). Preferably, when the structure of the insert 200 is implemented by injection molding or the like, the bending member 250 and the support body 230 can be integrally formed.

[0097] In some embodiments, in the storage frame portion 240 of the insert 200 according to one aspect of the disclosed technology, the storage slot 210 may be provided by the structure of the curved member 250. Figure 6 The storage frame portion 240 may include one bending member 250 or a plurality of bending members 250 , and may have various forms of the storage slots 210 based on the structure of the bending member 250 .

[0098] Reference Figure 6 The number of bending times of the bending member 250 and the bending direction of the bending member 250 may be independent for each bending member 250 disposed on the support body 230. The number of bending times of the bending member 250 and the bending direction of the bending member 250 may be appropriately designed in consideration of the type or size of the battery cell 300 to be accommodated.

[0099] In some embodiments, an insert 200 based on an aspect of the disclosed technology may include a plurality of storage frame portions 240, and the structure and shape of the storage frame portion 240 may be independent for each storage frame portion 240. The storage frame portion 240 may include: a first storage frame portion 240a, including a plurality of first curved members 250a; and a second storage frame portion 240b, including a single second curved member 250b. That is, the curved member 250 may include one or more curved members selected from the group consisting of a plurality of first curved members 250a and a single second curved member 250b. Here, the ordinal numbers added at the beginning of "first curved member 250a" and "second curved member 250b" are added only to distinguish the two, and have nothing to do with order or importance.

[0100] In the insert 200 according to one aspect of the disclosed technology, the first storage frame portion 240a may include the storage groove 210 due to the plurality of first curved members 250a. Figure 6 In the first storage frame portion 240a, a plurality of first curved members 250a may be disposed to be spaced apart from each other, and curved portions of the first curved members 250a may be arranged to face each other. Figure 6 , the bent portion may be the protrusion 250a-1. Figure 6 When the protrusions 250a-1 of the first curved member 250a are arranged facing each other as described above, the storage groove 210 may be naturally formed. In some embodiments, when the protrusions 250a-1 of the first curved member 250a are arranged facing each other while a plurality of first curved members 250a are spaced apart from each other as described above, a channel area 250a-2 may be formed between the protrusions 250a-1.

[0101] Here, although the first storage frame portion 240a is defined as the storage frame portion 240 including the plurality of first curved members 250a, as described above, the storage frame portion 240 in which the channel area 250a-2 is formed may be the first storage frame portion 240a.

[0102] In some embodiments, the separation gaps between the plurality of first curved members 250 a may be determined based on the shape and size of the battery cell 300 .

[0103] In the insert 200 according to one aspect of the disclosed technology, the second storage frame portion 240b may include the storage groove 210 due to the single second curved member 250b. Figure 6In the second storage frame portion 240b, a single second curved member 250b may be provided, and the second curved member 250b may have a shape that is bent multiple times. The position where the second curved member 250b is bent and the number of times the second curved member 250b is bent may be determined based on the shape and size of the battery cell 300. That is, the second curved member 250b may be bent multiple times and form the storage slot 210, and at least a portion of the battery cell 300 may be accommodated in the storage slot 210.

[0104] In some embodiments, the second storage frame portion 240b may include a protrusion 240b-1 that protrudes more than the first storage frame portion 240a due to the curved shape of the second curved member 250b. Figure 6 , the second storage frame portion 240b includes a protrusion 240b-1 that protrudes more than the first storage frame portion 240a, and the protrusion 240b-1 protrudes in the negative X-axis direction. Here, when the direction indicated by the arrow of the X-axis shown in the figure is the positive X-axis direction, the negative X-axis direction may be a direction that is 180° to the positive X-axis direction.

[0105] In some embodiments, reference Figure 6 , since the single second curved member 250b is bent multiple times to form the storage groove 210, a component such as the channel area 250a-2 formed by the multiple first curved members 250a is not formed. Here, although the second storage frame portion 240b is defined as a storage frame portion 240 including a single second curved member 250b, as described above, a storage frame portion 240 that does not form a component such as the channel area 250a-2, unlike the first storage frame portion 240a, may be the second storage frame portion 240b.

[0106] In some embodiments, reference Figure 6 , an insert 200 based on one aspect of the disclosed technology may include a first storage frame portion 240a and a second storage frame portion 240b. In some embodiments, the insert 200 may include a first storage frame portion 240a and a second storage frame portion 240b, and may have a structure in which the first storage frame portion 240a and the second storage frame portion 240b are arranged in sequence. That is, the insert 200 may have a structure in which, in a support body 230 having a shape that is longer in the longitudinal direction, the first storage frame portion 240a and the second storage frame portion 240b are arranged in sequence in the longitudinal direction of the support body 230 while being spaced apart from each other. Here, the separation gap between the first storage frame portion 240a and the second storage frame portion 240b may be determined based on the shape and size of the battery cell 300.

[0107] Reference Figure 6, the number of structures in which the first storage frame portion 240a and the second storage frame portion 240b are arranged in sequence and spaced from each other can be multiple. Here, for each structure, the separation gap between the first storage frame portion 240a and the second storage frame portion 240b can be independent. For example, the separation distances can be the same or different from each other. Considering space efficiency, the number of structures in which the first storage frame portion 240a and the second storage frame portion 240b are arranged in sequence and spaced from each other can be multiple, and for each structure, the separation gap between the first storage frame portion 240a and the second storage frame portion 240b can be the same.

[0108] In some embodiments, reference Figure 6 , there may be a plurality of structures in which the first storage frame portion 240a and the second storage frame portion 240b are sequentially arranged and spaced apart from each other, and there may also be an appropriate separation distance between the sequentially arranged structures. Here, the separation distances may be independent of each other, for example, the separation distances may be the same or different from each other. Considering space efficiency, the separation distances between the sequentially arranged structures may be the same.

[0109] Specifically, for example, refer to Figure 6 , the support body 230 has a shape that is long in the direction along the Y axis, and the insert 200 includes a plurality of structures that are sequentially arranged in the order of the first storage frame portion 240a and the second storage frame portion 240b in the direction along the Y axis. Figure 6 , the insert 200 may continuously include a structure arranged in the order of the first storage frame portion 240a and the second storage frame portion 240b. Here, "may continuously include" may mean that the structure arranged in the order of the first storage frame portion 240a and the second storage frame portion 240b is repeated at least twice or more. For example, the structure may be arranged in the order of the first storage frame portion 240a, the second storage frame portion 240b, the first storage frame portion 240a, the second storage frame portion 240b, and the first storage frame portion 240a.

[0110] In some embodiments, reference Figure 6 , separation distances between different pairs of the first storage frame portions 240a and the second storage frame portions 240b may be independent of each other and may be the same as each other.

[0111] In some embodiments, the insert 200 may include a plurality of structures in which the first storage frame portion 240a and the second storage frame portion 240b are sequentially arranged while being spaced apart from each other and may continuously include sequentially arranged structures. Figure 6, the separation distances between the sequentially arranged structures may be independent of each other and may be the same as each other. In some embodiments, the insert 200 may include structures sequentially arranged in the order of the first storage frame portion 240a and the second storage frame portion 240b, or may continuously include structures sequentially arranged in the order of the first storage frame portion 240a and the second storage frame portion 240b, but the insert 200 does not have to start with the first storage frame portion 240a or end with the second storage frame portion 240b. The structure of the insert 200 may be determined based on the shape and size of the battery cell 300.

[0112] Reference Figure 6 , the insert 200 includes a structure arranged in the order of the first storage frame portion 240a, the second storage frame portion 240b, the first storage frame portion 240a, the second storage frame portion 240b, and the first storage frame portion 240a, the second storage frame portion 240b, and the first storage frame portion 240a. That is, referring to Figure 6 The insert 200 may include a structure in which the first storage frame portion 240a and the second storage frame portion 240b are arranged in sequence, or may include a structure in which such structures are arranged continuously.

[0113] When the insert 200 includes a structure arranged in sequence in the order of the first storage frame portion 240a and the second storage frame portion 240b as described above, a battery storage tray 10 can be provided that can accommodate battery cells 300 of various types (e.g., multiple models) or sizes and allows the area for accommodating the battery cells 300 to be implemented through a convenient assembly method.

[0114] In some embodiments, when the insert 200 continuously includes a structure in which the first storage frame portion 240a and the second storage frame portion 240b are sequentially arranged in this order, the storage groove 210 may be provided due to the protrusion 240b-1 of one second storage frame portion 240b and another adjacent second storage frame portion 240b. Figure 6 A storage slot 210 that can accommodate at least a portion of the battery cell 300 may be provided between adjacent second storage frame portions 240b, wherein each second storage frame portion 240b includes a protrusion 240b-1 that protrudes along the negative X-axis direction.

[0115] That is, the insert 200 may include a storage frame portion 240 in which the storage slot 210 is provided by the curved member 250 itself. For example, the first storage frame portion 240a may have a storage slot 210 provided by a plurality of first curved members 250a, and the second storage frame portion 240b may have a storage slot 210 provided by a single second curved member 250b.

Specifically, referring to Fig.11 , multiple second coupling parts 220 can be coupled to the first coupling part 110. Here, the multiple inserts 200 coupled to one first coupling part 110 may or may not have a certain interval between them. That is, the multiple inserts 200 may or may not be in contact with each other at least partially. In some embodiments, as described above, the insert 200 may be implemented by injection molding or the like. Taking into account the injection molding tolerance occurring during the injection molding process or the assembly tolerance occurring when the multiple inserts 200 are coupled to the first coupling part 110, the multiple inserts 200 may be coupled to the first coupling part 110 with a minimum interval therebetween. When the multiple inserts 200 are coupled to the first coupling part 110 with a minimum interval therebetween, the inserts 200 and the first coupling part 110 may be more easily coupled and disconnected, and damage to the inserts 200 or the first coupling part 110 may be minimized. In another example, referring to Fig.11 , when there is no injection tolerance or assembly tolerance, the plurality of insert members 200 may contact each other in consideration of space utilization.

[0148] In some embodiments, reference Fig.12 , the width W and length L of the battery storage portion 260 provided by the storage slots 210 of the first insert 200a and the second insert 200b may vary based on the appropriate structural design of each insert 200, the position of the insert 200, and the position of the auxiliary coupling portion 111 to which the insert 200 is coupled, etc. That is, by changing the structural design, coupling position, etc. of the insert 200, the battery storage tray 10 may include a battery storage portion 260 having a width W and a length L suitable for accommodating the battery cells 300. The contents regarding the width W and the length L of the battery storage portion 260 are as described above, and therefore, the description thereof will be omitted below unless otherwise specified.

[0149] In some embodiments, here, the width W may be the dimension between two points on the battery storage portion 260 with the largest straight-line distance, and the length L may be the dimension between two points on the battery storage portion 260 that are perpendicular to the width W and may be the shortest straight-line distance. That is, in the battery storage portion 260, the width W may be greater than the length L. In the disclosed technology, when the width W and the length L are the same size, they may both be referred to as the width W or the length L.

[0150] Reference Fig.13 , showing Fig.12The battery storage unit 260 shown in FIG. 2 contains all the battery cells 300. The battery cells 300 may each include an external material 310 in which an electrode assembly 320 may be embedded. In some embodiments, the battery cells 300 may each include one or more terminals 340 (see FIG. 3 ). Fig.18 and Fig.19 ), the one or more terminals 340 protrude in one direction of the external material 310 in a direction not facing the inner space 100a of the receiving portion 100, and are electrically connected to the electrode assembly 320. That is, in Fig.13 In the embodiment, the battery cell 300 can be accommodated in the battery storage portion 260 so that at least some of the terminals 340 of the battery cell 300 protrude in the positive Z-axis direction. When the terminals 340 protrude as described above, formation or testing that may be performed during the activation process can be more easily performed. For example, when a probe used in formation or testing that may be performed during the activation process contacts the protruding terminals 340, formation or testing can be more easily performed. The details of the battery cell 300 will be described below.

[0151] Reference Fig.13 The shape of the battery storage portion 260 may be determined based on the shape of the outer material 310 of the battery cell 300 to be accommodated. Fig.13 When the outer material 310 of the battery cell 300 has a prismatic hexahedral shape, the battery storage portion 260 may have an appropriate shape to store the prismatic hexahedral shape, and for this purpose, the storage frame portion 240 or the bending member 250 of the insert 200 may be designed to be suitable therefor.

That is, referring to Fig.13 , the battery cells 300 accommodated in the battery storage portion 260 may be described as being accommodated along a Y-axis direction which is a width W direction of the battery storage portion 260 .

[0153] Here, when the width W and the length L of the battery storage portion 260 are the same, the accommodation direction of the battery cell 300 may be determined based on the width W direction of the battery cell 300. The width W of the battery cell 300 may be the dimension of the long side on a plane (XY plane) excluding the direction in which the terminal 340 of the battery cell 300 protrudes (e.g., the Z-axis direction). Likewise, the length L may be smaller than the width W and may be the dimension of the short side.

[0154] When the width W and length L of the battery cell 300 are also the same, the accommodation direction of the battery cell 300 can be determined based on the width W direction of the accommodation portion 100. The width W of the accommodation portion 100 can be the size of the long side on the plane (XY plane) except for the direction in which the terminal 340 of the battery cell 300 protrudes (for example, the Z-axis direction). Similarly, the length L can be smaller than the width W and can be the size of the short side. In some embodiments, when the width W and length L of the accommodation portion 100 are also the same, the accommodation direction of the battery cell 300 can be determined.

[0155] Fig.14 The state of the battery storage tray 10 shown shows that although the battery storage tray 10 has Fig.12 The battery storage tray 10 shown has the same structure, but the battery storage portion 260 can be interpreted differently.

Fig.16 , one or more inserts 200 may be disposed across the inner space 100a of the receiving portion 100 along the Y-axis direction. Since the insert 200 is the same as described above except for the direction in which the insert 200 is disposed across the inner space 100a of the receiving portion 100, further description of the insert 200 will be omitted below.

In some embodiments, Fig.16 The insert 200 in the embodiment includes a structure that is sequentially arranged in the order of the first storage frame portion 240a and the second storage frame portion 240b. In such a structure, the storage slot 210 (see FIG. 210 ) can be provided due to the protrusion 240b-1 of one second storage frame portion 240b and the adjacent protrusion 240b-1 of another second storage frame portion 240b.

[0162] exist Fig.16 In FIG. 2 , based on the above description, the entire dotted line frame may represent the battery storage portion 260 , and the battery cells 300 may be accommodated in the battery storage portion 260 .

[0163] Reference Fig.17 , showing Fig.16 , all the battery cells 300 are accommodated in the battery storage portion 260. The accommodated battery cells 300 can be described as being accommodated along the Y-axis direction, which is the width W direction of the battery storage portion 260. Fig.17 , when the battery cells 300 are accommodated along the Y-axis direction, a maximum of 28 battery cells 300 can be accommodated.

[0165] For example, refer to Fig.13 When all the multiple inserts 200 are arranged across the inner space 100a of the receiving portion 100 along the X-axis direction (i.e., the first direction), the maximum number N1 of battery cells 300 that can be accommodated in the Y-axis direction (i.e., one direction) may be 28. In some embodiments, referring to Fig.17 When all of the plurality of inserts 200 are arranged across the internal space 100a of the receiving portion 100 along the Y-axis direction (ie, the second direction), the maximum number N2 of battery cells 300 that can be accommodated in the Y-axis direction (ie, one direction) may also be 28.

[0166] In some embodiments, the first direction and the second direction may be perpendicular to each other.

[0167] In the battery storage tray 10 based on one aspect of the disclosed technology, the array P1 of the battery storage section 260 when the plurality of inserts 200 are arranged across the internal space 100a of the receiving section 100 in the first direction to allow the maximum number N1 of battery cells 300 to be accommodated and the array P2 of the battery storage section 260 when the plurality of inserts 200 are arranged across the internal space 100a of the receiving section 100 in the second direction to allow the maximum number N2 of battery cells 300 to be accommodated may be identical to each other. In the disclosed technology, the array of the battery storage section 260 may be the positions of the rows and columns of all the battery storage sections 260 provided in the battery storage tray 10 and the width W and length L associated with the positions.

[0168] For example, in Fig.12 In the embodiment, the array P1 of the battery storage portion 260 when a plurality of inserts 200 are arranged along the X-axis direction (i.e., the first direction) across the inner space 100a of the receiving portion 100 to allow for the maximum number N1 of battery cells 300 to be accommodated is shown in a dotted frame.

Here, the array P1 and the array P2 may be the same. In this way, formation or testing that may be performed during the activation process may be performed more easily.

[0169] In some embodiments, since the arrays P1 and P2 are the same, the centers of the terminals 340 of the battery cells 300 can be the same. Since the centers of the terminals 340 are the same in the same arrays P1 and P2, when performing formation or other tests, even if the type of the battery cells 300 changes, it is not necessary to change the structure of the receiving portion 100 and / or the insert 200 itself or change the position of the probe. In this way, a battery storage tray 10 that can accommodate various types (e.g., multiple models) of battery cells 300 and allows the area for accommodating the battery cells 300 to be implemented by a convenient assembly method can be provided.

In another example, the battery cell 300 may include electrodes (cathode 321 and anode 322) and a solid electrolyte layer, and the solid electrolyte layer may serve as a separator 323 while allowing electron transport materials to pass through. Here, the electron transport material may be lithium ions (Li+). In some embodiments, the battery cell 300 including the solid electrolyte layer may be an all-solid battery.

[0172] The electrode assembly 320 may include an electrode. The electrode may be a term covering the cathode 321 and the anode 322. In some embodiments, the electrode assembly 320 may include a separator 323 to prevent a short circuit between the cathode 321 and the anode 322. The separator 323 may be interposed between the cathode 321 and the anode 322.

[0173] The electrode assembly 320 may be manufactured by winding the cathode 321, the anode 322, and the separator 323 into a vertically long sheet. Alternatively, the electrode assembly 320 may be manufactured by a stacking method (e.g., a Z stacking method) in which the cathode 321 and the anode 322 cut into appropriate sizes are inserted between the separators 323 in the vertically long sheet.

[0176] The electrolyte is a medium that enables electron transport materials (eg, lithium ions) to move to promote an electrochemical reaction between the cathode 321 and the anode 322. The electrolyte may generally include an organic solvent and a lithium salt, and the organic solvent and the lithium salt may be known in the art.

[0177] Here, the battery is classified into various types based on the type of electron transport material. For example, when the electron transport material is lithium (Li, including ions), the battery is called a lithium-ion battery.

[0178] In some embodiments, as described above, the outer material 310 can protect the electrode assembly 320 from external impact and prevent the electrolyte from leaking to the outside (that is, seal the electrolyte from the outside). Based on the shape of the outer material 310, the battery cell 300 can be divided into a prismatic shape, a cylindrical shape, and a pouch shape. In the disclosed technology, it may be advantageous for the battery cell 300 to be a prismatic battery cell 300.

Fig.19, the cathode tab 324a and the anode tab 324b may protrude in the same direction. In this case, the tab 324 may be referred to as a unidirectional tab 324.

[0181] The battery cell 300 based on one aspect of the disclosed technology may include a cover 330, which includes a terminal 340. The cover 330 may seal the surface of the external material 310 of the battery cell 300 that is open to embed the electrode assembly 320, etc. In some embodiments, the terminal 340 included in the cover 330 may be electrically connected to the pole ear 324 of the electrode assembly 320 by welding, etc., and the terminal 340 may protrude from at least one surface of the cover 330. The cover 330 may be coupled to the external material 310 and sealed, and generally, the coupling may be performed by welding. When the cover 330 and the external material 310 are coupled, the terminal 340 may protrude from the external material 310 in one direction.

[0182] In some embodiments, reference Fig.18 and Fig.19 , the cathode tab 324a can be electrically connected to the cathode terminal 340a, and the anode tab 324b can be electrically connected to the anode terminal 340b. Fig.18 , the cathode terminal 340a and the anode terminal 340b protrude in different directions from each other, and the battery cell 300 in this case may be referred to as a bidirectional battery cell 300. In some embodiments, referring to Fig.19 , the cathode terminal 340 a and the anode terminal 340 b protrude in the same direction as each other, and the battery cell 300 in this case may be referred to as a unidirectional battery cell 300 .

In some embodiments, based on another aspect of the disclosed technology, a battery storage tray may be provided that may implement an area for accommodating battery cells through a convenient assembly method.

[0184] The disclosed technology can be implemented to manufacture rechargeable secondary batteries, which are widely used in battery-powered devices or systems, including, for example, digital cameras, mobile phones, laptops, hybrid vehicles, electric vehicles, uninterruptible power supplies, battery energy storage power stations, and battery power storage including for solar panels, wind turbines and other green technology generators. Specifically, the disclosed technology can be implemented in some embodiments to manufacture improved electrochemical devices such as batteries for various power sources and power supplies, thereby alleviating climate change related to the use of power sources and power supplies. Secondary batteries made using the disclosed technology can be used to address various adverse effects (such as air pollution and greenhouse gas emissions) by powering electric vehicles (EVs) as an alternative to vehicles using fossil fuel engines and providing battery-based energy storage systems (ESS). Such secondary batteries can include, for example, lithium-ion batteries, nickel-cadmium batteries, nickel-metal hydride batteries, and nickel-hydrogen batteries.
