FIG. 1 is an exploded perspective view showing a label unit of the present disclosure and a battery pack having the same.

As shown in FIG. 1 , a battery pack 1 according to an embodiment of the present disclosure may include a case 10, a plurality of battery cells 30 and a protection circuit module (PCM) 50 coupled to the case 10 and attached as a battery cell. The first label 100 and the second label 100 ′ of the battery cell 30 are covered in a state where the body 30 and the protection circuit module 50 are combined to the case 10 . Together, the first label 100 and the release paper or the remainder of the release paper may be referred to as a label unit.

Each battery cell 30 may have a general structure in which an electrode assembly is accommodated in a battery case together with an electrolyte. In the present disclosure, three battery cells 30 may be provided by way of example. As shown in FIG. 1 , three battery cells 30 may be arranged such that the length direction of the battery cells 30 and the length direction of the case 10 are the same. The protection circuit module 50 may be electrically connected to the battery cell 30 .

A protection circuit module 50 including a circuit board and a connector is electrically connected to tabs and the outside of the battery cell 30 . The protection circuit module 50 includes a protection circuit for protecting the battery cell 30 from overcharging, overdischarging and overcurrent. A protection circuit may be formed on the circuit board. The protection circuit module 50 may be disposed in a region between the battery cells 30 and the case 10 to minimize an increase in the thickness of the battery pack 1 . For example, the protection circuit module 50 of the present disclosure may be arranged in a substantially "U" shape.

After the battery cell 30 and the protection circuit module 50 are installed in the case 10, the first label 100 and the second label 100' may be attached to the lower and upper parts of FIG. 1, respectively.

Fig. 2 is a plan view showing a state where a release paper is attached to a label according to the first embodiment of the present disclosure. 3 is a plan view showing a state where a part of the release paper is removed from the label of FIG. 2 (for convenience, based on FIGS. 2 and 3 , the upper side and the lower side are defined as upper and lower parts, respectively, and the following description will be made) .

As shown in FIG. 1 , a first label 100 and a second label 100 ′ according to an embodiment of the present disclosure are used to cover the battery cell 30 and the protection circuit module 50 . The first label 100 and the second label 100 ′ may include an adhesive layer to be attached to the battery cell 30 , the protection circuit module 50 and the case 10 . The adhesive layer of the first label 100 may be disposed on a surface facing the battery cell 30 and the protection circuit module 50 . The first label 100 may include a first region 110 , a second region 120 and a third region 130 respectively attached to the plurality of battery cells 30 . The adhesive layer of the second label 100 ′ may be provided on a surface facing the case 10 . Release paper may be attached to the first label 100 and the second label 100'. After the release paper 200 of the first label 100 is partially removed in a state where a part thereof remains, the first label 100 may be attached to cover the battery cells 30 and the protection circuit module 50 . For example, the area where the release paper 200 is partially left may be the second area 120 of the first label 100 . After the release paper of the second label 100 ′ is completely removed, the second label 100 ′ may be attached to cover the case 10 and the battery cells 30 .

Hereinafter, specific structures of the release paper and the first label and a method for removing the release paper will be described in detail.

As shown in FIG. 2 , a release paper 200 may be attached to the first label 100 . The release paper 200 may have a size and shape corresponding to the size and shape of the first label 100, and/or may be formed to have a size larger than that of the first label 100 (in this disclosure, the latter case will be exemplified describe).

As shown in FIGS. 2 and 3 , the release paper 200 may include a removed portion 210 removed to expose the adhesive layer of the first label 100 and a remaining portion 230 left attached to the first label 100. .

The removed part 210 is a part removed from the release paper 200 to adhere the first label 100 to the battery cell 30 . A part of the removal part 210 is not removed but remains on the first label 100 . A portion of the release paper remaining on the first label 100 is defined as a remaining portion 230 .

For example, the release paper 200 may have a remaining portion 230 having a shape corresponding to the shape of the protection circuit module 50 in a substantially "U" shape (an inverted "U" shape based on FIGS. 2 and 3 ). The remaining part 230 may be formed to have the same size as that of the protection circuit module 50 or to have a size larger than that of the protection circuit module 50 . In order to prevent noise from being generated due to the gap between the protection circuit module 50 and the battery cell 30 , the remaining portion 230 corresponding to the position of the protection circuit module 50 is left without being removed. For this, the remaining part 230 may have a shape substantially corresponding to that of the protection circuit module 50 . However, since the remaining part 230 is a non-adhesive release paper, an adhesive part for fixing the protection circuit module 50 should be included. For this, the "U"-shaped remaining part 230 may be divided into two pieces to be spaced apart from each other. For example, the "U"-shaped remaining portion 230 may be vertically divided into two pieces and arranged to be spaced apart from each other. That is, the remainder 230 may include a first remainder 232 and a second remainder 234 .

2, the first remaining part 232 may include a first side part 232a and a first extension part 232b, the first side part 232a is arranged in a direction perpendicular to the length direction of the release paper 200, and the first extension part 232b extends from the first One end of the side portion 232a extends approximately vertically. The second remaining part 234 may include a second side part 234a spaced parallel to the first side part 232a and a second extension part 234b substantially vertically extending from one end of the second side part 234a. The first extension 232b and the second extension 234b may face each other and may be spaced apart from each other. The removal part 210 may be divided into a plurality of regions so that the release paper 200 may be easily removed with the first remaining part 232 and the second remaining part 234 remaining.

For example, the release paper 200 may include the first removal part 212 provided on the lower part of the first remaining part 232 and the second remaining part 234, the second removal part 214 provided at one side of the first remaining part 232, and the second removal part 214 provided at the second remaining part 232. The third removal portion 216 at one side of the second remaining portion 234 .

Here, the first remaining portion 232 and the second remaining portion 234 may be spaced apart from each other and symmetrically disposed.

The first removal part 212 is provided on the lower side of the release paper 200 . For example, when the release paper 200 is divided into two pieces in the width direction, the first removal part 212 may occupy an area equal to or smaller than the lower half of the release paper 200 . Based on the first label 100 shown in FIG. 3 , the first removal part 212 corresponds to a region covering the lower portion of the first region 110 to the third region 130 of the first label 100 . Here, a lower portion of the first remaining portion 232 may extend to a partial area of the first removed portion 212 . In the first removed portion 212, all remaining regions except the end portion of the first remaining portion 232 are connected as one piece. Therefore, when the first removal part 212 is removed, the first removal part 212 may be removed from the first label 100 with the lower side of the first remaining part 232 remaining.

The second removal part 214 is provided on the upper right side of the first removal part 212 . The third removal part 216 is provided on the upper left side of the first removal part 212 . Based on the first label 100 shown in FIG. 3 , the second removed part 214 and the third removed part 216 correspond to regions covering upper parts of the first to third regions 110 to 130 . For example, the second removal part 214 and the third removal part 216 may be configured to be divided into two pieces by dividing a sheet of release paper in a region between the first extension part 232b and the second extension part 234b. Therefore, the second removed part 214 and the third removed part 216 may be symmetrical to each other.

When the second removal part 214 and the third removal part 216 are removed, all areas of the release paper 200 except the first remaining part 232 and the second remaining part 234 should be removed. For this reason, the second removal part 214 is configured such that the first region 214a which is the right region of the first remaining part 232 and the second region 214b which is the region between the first remaining part 232 and the second remaining part 234 are connected by Regions 214c are connected to each other as one piece. Likewise, the third removing part 216 is configured such that the first region 216a which is the left region of the second remaining part 234 and the second region 216b which is the region between the first remaining part 232 and the second remaining part 234 are connected by Regions 216c are connected to each other as one piece. Therefore, when the second removal part 214 and the third removal part 216 are removed, the first regions 214a and 216a, the second regions 214b and 216b, and the connecting regions 214c and 216c connecting them are all connected, so that except for the first remaining part 232 and All release paper 200 other than the second remainder 234 is removed. After the release paper 200 is removed, on the first label 100, the first remaining portion 232 and the second remaining portion 234 may remain spaced apart from each other as a region of the connecting area in the release paper 200 (indicated by A in FIG. 3 ). instruct).

If the regions A are connected as one body without being spaced apart from each other, the first regions 214a and 216a and the second regions 214b and 216b of the second and third removal parts 214 and 216 cannot be connected to each other. Therefore, the release papers of the first regions 214a and 216a need to be removed separately. In addition, if the removal of the release paper in the first regions 214a and 216a is omitted, the thickness of the corresponding portions will be increased. This means that the thickness of undesired portions may increase, leading to the danger of thickness defects. To solve this problem, the first remaining part 232 and the second remaining part 234 should be arranged to be spaced apart from each other, and the release paper to be removed (the second removing part and the third removing part) are integrally connected so that the releasing paper can be easily removed.

In the present embodiment, the release paper 200 including the first to third removal parts 212 to 216 has been described as an example, but the first to third removal parts 212 to 216 may include a single sheet of release paper. Optionally, the release paper 200 may also include two pieces of release paper separated left and right in the space area between the first remaining part 232 and the second remaining part 234 . However, by configuring the release paper to be separated in the narrow area, it is easy to remove the release paper in the narrow area. Accordingly, the release paper may be configured to separate in the spaced-apart region between the first remainder 232 and the second remainder 234 . This is equally applicable even when the number of sheets of the remainder increases.

Fig. 4 is a plan view showing a state where a release paper is attached to a label according to a second embodiment of the present disclosure. Fig. 5 is a plan view showing a state where a part of the release paper is removed from the label of Fig. 4 . 6 is a plan view showing a state where a release paper is attached to a label according to a third embodiment of the present disclosure. Fig. 7 is a plan view showing a state where part of the release paper is removed from the label of Fig. 6 (detailed description of the same features as those of the above-described embodiment will be omitted).

As shown in FIG. 4, according to the second embodiment, a release paper 400 may be attached to the first label 100a. The release paper 400 may include a first remaining part 431 to a fifth remaining part 435 (collectively referred to as a remaining part 430 ), a first removed part 412 and a second removed part 414 (collectively referred to as a removed part 410 ).

For example, the first removal part 412 may be provided on the lower side, and the second removal part 414 may be provided on the upper side. The first removal part 412 and the second removal part 414 may be provided to vertically divide the release paper 400 into two pieces.

Similar to the remainder of the first embodiment, the first to fifth remainders 431 to 435 may have an inverted 'U' shape, but may be divided into five pieces and disposed to be spaced apart from each other. In addition, the first remaining portion 431 and the fifth remaining portion 435 may be provided at the first removal portion 412 side, and the second remaining portion 432, the third remaining portion 433, and the fourth remaining portion 434 may be provided at the second removal portion. 414 side. The first removal part 412 and the second removal part 414 may be configured such that a sheet of release paper is removed between the first remaining part 431 and the second remaining part 432 and between the fourth remaining part 434 and the fifth remaining part 435. Divide into two pieces. Here, in the first removal part 412 and the second removal part 414 , the first remaining part 431 and the second remaining part 432 and the fourth remaining part 434 and the fifth remaining part 435 may be connected by connection parts 412a and 414a, respectively. The second remaining part 432 and the third remaining part 433 and the third remaining part 433 and the fourth remaining part 434 may also be connected by the connection part 414b.

Although the release paper is separated into the first removal part 412 and the second removal part 414, the first removal part 412 and the second removal part 414 should be at all areas except the first remaining part 431 to the fifth remaining part 435 connect. Therefore, in the first removal portion 412 and the second removal portion 414, the region of the first removal portion 412 between the first remaining portion 431 to the fifth remaining portion 435 (indicated by 412a, 414a, and 414b in FIG. area) is formed to be connected at the first removal portion 412 or the second removal portion 414 side. That is, when the first removal part 412 is removed, the first removal part 412 can be removed at one time because the connection part 412a is connected as one. Likewise, when the second removal part 414 is removed, the connection part 414a is connected as a whole, so that the second removal part 414 is removed at one time.

As shown in FIG. 5 , when the first removal part 412 and the second removal part 414 are removed, only the first remaining part 431 to the fifth remaining part 435 remain on the first label 100 . Here, the first to fifth remaining portions 431 to 435 remain spaced apart from each other (indicated by B in FIG. 5 ).

In addition, as shown in FIG. 6, according to the third embodiment, a release paper 600 may be attached to the first label 100b. The release paper 600 may include a first removed part 612 , a second removed part 614 (collectively referred to as the removed part 610 ), and first to third remaining parts 631 to 633 (collectively referred to as the remaining part 630 ). Similar to the remaining part of the first embodiment, the first remaining part 631 to the third remaining part 633 may have an inverted "U" shape, but may be divided into three pieces and arranged to be spaced apart from each other. In the release paper 600, the regions corresponding to the second remaining part to the fourth remaining part 432, 433 and 434 of FIGS. 614 side. In addition, the release paper 600 may be configured such that the first remaining part 631 and the third remaining part 633 are disposed at the first removal part 612 side. In this case, the first removal part 612 and the second removal part 614 may be configured such that a sheet of release paper is placed between the first remaining part 631 and the second remaining part 632 and between the second remaining part 632 and the third remaining part 632 . The remaining part 633 is separated into two pieces.

Although the release paper is separated into the first removal part 612 and the second removal part 614, the first removal part 612 and the second removal part 614 should be at all areas except the first remaining part 631 to the third remaining part 633 connect. Therefore, in the first removal part 612 and the second removal part 614 , the first remaining part 631 to the third remaining part 633 are connected by the connecting regions 612 a and 614 a. That is, when the first removal part 612 is removed, since the first removal part 612 is connected in one body by the connection region 612a, the first removal part 612 can be removed at one time. Likewise, when removing the second removed part 614, since the second removed part 614 is connected in one body by the connecting region 614a, the second removed part 614 can be removed at one time.

As shown in FIG. 7 , after the first removal part 612 and the second removal part 614 are removed, only the first remaining part 631 to the third remaining part 633 may remain on the first label 100b. Here, the first remaining part 631 to the third remaining part 633 may remain at an interval (indicated by C in FIG. 7 ) spaced apart from each other as a region of the connection region in the release paper 600 .

As described above, it is possible to easily remove the release paper in unnecessary areas while leaving only the release paper in necessary areas (corresponding to the remainder), thereby preventing thickness defects. In addition, noise generation due to empty spaces such as gaps can be improved by leaving the release paper in a partial area (empty space) of the component assembly portion.

While the foregoing embodiments have been described to practice the present disclosure, it should be understood that the embodiments described therein should be considered as illustrative only and not for purposes of limitation, and without departing from the scope of the appended claims. Various changes in form and details may be made within the spirit and scope of the disclosure.
