A mobile phone is an electronic device equipped with a cellular communication module.

[0013] This application first provides a battery easy-tear sticker, which is used to attach to the outer surface of a battery cell. Please refer to [link to relevant documentation]. Figure 2 , Figure 2 This is a schematic diagram of a battery easy-tear sticker according to an embodiment of the present application. The battery easy-tear sticker 100 includes: a protective film 110 and an adhesive layer 120 disposed on one side surface of the protective film 110.

[0014] Specifically, the adhesive layer 120 includes multiple sets of adhesive units 121, please refer to the following: Figure 3 , Figure 3 yes Figure 2 The schematic diagram of the bonding unit in the embodiment shows that each bonding unit 121 includes at least two adhesive strips 1210 arranged crosswise (two adhesive strips 1210 in the figure of this embodiment). The adjacent adhesive strips 1210 are arranged at an acute angle along the first direction (arrow X in the figure). The first direction X is the direction in which the battery easy-tear sticker is peeled off and the battery cell is removed, that is, the direction of tearing.

[0015] Optionally, the included angle α between adjacent adhesive strips 1210 along the first direction X is greater than 0 degrees and less than 45 degrees. In some optional embodiments, specifically, the included angle α between adjacent adhesive strips 1210 along the first direction X is greater than 0 degrees and less than 30 degrees. The design of the above angle is based on a comprehensive consideration of the bonding area and tear strength. The technical solution in this application uses cross-shaped strip adhesive paper instead of regular round dots. While ensuring that the easy-tear pull force does not increase or increases only slightly, the adhesive area is significantly increased to increase the adhesive force and ensure that the battery can be bonded better.

[0016] In this embodiment, multiple sets of adhesive units 121 are arranged along a second direction (arrow Y in the figure), and the second direction Y is perpendicular to the first direction X. The arrangement and extension direction of the adhesive strips 1210 in each adhesive unit 121 are the same, and the width and length of the adhesive strips 1210 in each adhesive unit 121 can also be the same.

[0017] Please refer to the following: Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of another embodiment of the battery easy-tear sticker of this application. Figure 5 yes Figure 4 The schematic diagram of the adhesive unit in the embodiment shows that the battery easy-tear sticker 100 in this embodiment may also include: a protective film 110 and an adhesive layer 120 disposed on one side surface of the protective film 110.

[0018] The adhesive layer 120 includes multiple sets of bonding units 121. In this embodiment, each bonding unit 121 includes three intersecting adhesive strips 1210. Adjacent adhesive strips 1210 are set at an acute angle along a first direction (arrow X in the figure). The first direction X is the direction in which the battery easy-tear sticker is peeled off to remove the battery cell, i.e., the tearing direction. Optionally, the included angle α between adjacent adhesive strips 1210 along the first direction X is greater than 0 degrees and less than 45 degrees. In some optional embodiments, the included angle α between adjacent adhesive strips 1210 along the first direction X is greater than 0 degrees and less than 30 degrees. The above angle design is based on a comprehensive consideration of the bonding area and tear strength. The technical solution in this embodiment uses intersecting strip adhesive paper instead of regular round dots. While ensuring that the easy-tear sticker's tensile strength does not increase or increases only slightly, the adhesive area is significantly increased to increase the adhesive force and ensure that the battery can be bonded better.

[0019] In this embodiment, multiple sets of adhesive units 121 are arranged along a second direction (arrow Y in the figure), where the second direction Y is perpendicular to the first direction X. The adhesive strips 1210 within each adhesive unit 121 have the same arrangement and extension direction; alternatively, the width and length of the adhesive strips 1210 within each adhesive unit 121 can also be the same. Furthermore, in this embodiment, the adhesive units 121 are arranged along the second direction Y to form multiple columns (two columns are shown in the figure; please refer to both). Figure 6 , Figure 6 This is a schematic diagram of another embodiment of the battery easy-tear adhesive of this application. In this embodiment, the adhesive units 121 are arranged in three columns. Of course, in some other embodiments, there may be four columns or more columns (which will not be listed and described in detail here). The extension direction of each column is perpendicular to the first direction X.

[0020] Please refer to the following: Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of another embodiment of the battery easy-tear sticker of this application. Figure 8 This is a schematic diagram of another embodiment of the battery easy-tear adhesive of this application; unlike the previous embodiments where the arrangement and extension direction of the adhesive strips 1210 in each adhesive unit 121 are the same, and the width and length of the adhesive strips 1210 are the same, in... Figure 7 and Figure 8 In the embodiments, the arrangement of the bonding units 121 and the width and length of the adhesive strips 1210 can be different. The bonding units 121 can be arranged in an identical row or they can be different from each other, as long as each bonding unit includes at least two adhesive strips arranged in a cross pattern, and the adjacent adhesive strips are arranged at an acute angle along the first direction X. Various combinations of arrangements of the bonding units 121 and the width and length of the adhesive strips 1210 are beyond the understanding of those skilled in the art and will not be listed or described in detail here.

[0021] The battery easy-tear sticker provided in this application embodiment, by designing a cross-shaped strip adhesive structure, can still be easily torn off while ensuring reliable adhesion and preventing detachment. It has the characteristics of simple structure and easy removal.

[0022] In the aforementioned embodiments, the adhesive strip 1210 is of uniform thickness and has rectangular or rounded ends. In some other embodiments, the adhesive strip 1210 may also have a non-uniform thickness or width; please refer to those embodiments as well. Figures 9 to 11 , Figure 9 This is a schematic diagram of another embodiment of the bonding unit of this application, wherein the adhesive strip 1210 in this embodiment can be a structure that is wide in the middle and narrow at both ends. Figure 10 This is a schematic diagram of another embodiment of the adhesive unit of this application. In this embodiment, the end of the adhesive strip 1210 is a pointed (or triangular) structure, and the end gradually narrows along the first direction X. The purpose of this design is to make it easier to tear open by hand near the edge. Please refer to... Figure 11 , Figure 11 This is a structural schematic diagram of another embodiment of the adhesive unit of this application. The end of the adhesive strip 1210 is not limited to a continuously changing triangle or cone shape, but can also be an ellipse or an irregular shape, as long as the adhesive area is smaller closer to the edge (gradually narrowing along the first direction X).
