[0118] Reference Figure 1 and Figure 2 , the length, width and height H1 of each of the multiple internal joints 500 may be the same or different. Here, the height H1 of the internal joint 500 may refer to the height of the protruding area, that is, the length protruding from the inner wall 100b. The heights H1 of the multiple internal joints 500 according to one aspect of the present disclosure may be the same. Here, the same means basically the same, and may refer to exactly the same value, or may refer to a situation where even if the values ​​are different, the difference is within 10%. In addition, the height H1 may refer to the distance between the lowest position and the highest position when the Z-axis direction is used as a reference. If the heights H1 of the multiple internal joints 500 are made the same, the bonding stability can be better ensured when the insert 200 is built into the accommodating portion 100.

[0119] In addition, the height H1 of the inner joint portion 500 may be at least 1%, at least 3%, or at least 5% of the height of the receiving portion 100 to ensure the direction of the terminal 340 of the battery cell 300, the protruding length of the terminal 340, and the bonding stability of the insert 200.

[0229] The electrode assembly 320 may be manufactured by winding a positive electrode 321, a negative electrode 322, and a separator 323 in the form of a longitudinally long sheet. Alternatively, the electrode assembly 320 may be manufactured by stacking (e.g., Z-type stacking) a positive electrode 321 and a negative electrode 322 cut to a suitable size between separators 323 in the form of longitudinally long sheets. Fig.17 and Fig.18 The electrode assembly 320 shown is manufactured by stacking, and the manufacturing method of the electrode assembly 320 described in the present disclosure is not limited to a certain method.

[0230] The cathode 321 may refer to a reduction electrode where an electron transfer substance receives electrons when the battery cell 300 is discharged. The cathode 322 may refer to an oxidation electrode where an electron transfer substance transfers electrons when the battery cell 300 is discharged. In addition, the separator 323 refers to a membrane that prevents an electrical short circuit between the cathode 321 and the cathode 322 while allowing the electron transfer substance to pass through. Here, the electron transfer substance may be lithium ions (Li+).

[0231] In addition, the battery cell 300 may have a structure in which the electrode assembly 320 is built in a space enclosed by the exterior material 310 and filled with electrolyte. The term enclosed space used in the present disclosure may refer to a space enclosed to such an extent that when a liquid substance exists in the space, the liquid substance does not leak to the outside.

[0232] The electrolyte refers to a medium that allows electron transfer substances (eg, lithium ions) to move to promote electrochemical reactions between the positive electrode 321 and the negative electrode 322. The electrolyte generally includes an organic solvent and a lithium salt, which may include organic solvents and lithium salts known in the art.

[0233] There are many types of batteries depending on the type of the electron transfer material. For example, if the electron transfer material is lithium (Li, containing ions), the battery is called a lithium-ion battery.

[0234] In addition, as described above, the outer packaging material 310 can protect the electrode assembly 320 from external impact and prevent the electrolyte from leaking to the outside (i.e., sealing). According to the shape of the outer packaging material 310, the battery cell 300 can be distinguished as a prismatic, cylindrical, or bag-shaped. In the present disclosure, the battery cell 300 is preferably a prismatic battery cell 300.

[0235] In the battery cell 300 according to one aspect of the present disclosure, the electrode assembly 320 may include a tab 324. The tab 324 may include a positive tab 324a electrically connected to the positive electrode 321 and a negative tab 324b electrically connected to the negative electrode 322. The tab 324 may protrude from at least one side of the electrode assembly 320.

[0236] Reference Fig.17 , the positive electrode tab 324a and the negative electrode tab 324b can protrude in different directions. The tab 324 in this case can be called a bidirectional tab 324. Fig.18 , the positive electrode tab 324a and the negative electrode tab 324b can protrude in the same direction. The tab 324 in this case can be called a unidirectional tab 324.

[0237] The battery cell 300 according to one aspect of the present disclosure may include a cover 330, which includes a terminal 340. The cover 330 may seal an open surface for embedding the electrode assembly 320 and the like in the outer packaging material 310 of the battery cell 300. In addition, the terminal 340 included in the cover 330 may be electrically connected to the tab 324 of the electrode assembly 320 by welding or the like, and the terminal 340 may protrude from at least one side of the cover 330. The cover 330 may be combined with the outer packaging material 310 for sealing, and the combination may generally be performed by welding. When the cover 330 is combined with the outer packaging material 310, the terminal 340 may protrude from the outer packaging material 310 in one direction.

[0238] In addition, refer to Fig.17 and Fig.18 , the positive electrode tab 324a can be electrically connected to the positive electrode terminal 340a, and the negative electrode tab 324b can be electrically connected to the negative electrode terminal 340b. Fig.17 , the positive terminal 340a and the negative terminal 340b may protrude in different directions, and the battery cell 300 in this case may be called a bidirectional battery cell 300. Fig.18 , the positive terminal 340a and the negative terminal 340b protrude in the same direction. In this case, the battery cell 300 can be called a unidirectional battery cell 300.

[0239] The above description is merely an example of applying the principles of the present disclosure, and other configurations may also be included without departing from the scope of the present disclosure.
