[0038] The following reference Figures 1 to 4 This application describes protective film tapes and batteries according to some embodiments.

[0039] See Figures 1 to 4 As shown, an embodiment of the first aspect of this application provides a protective film tape, which includes an attachment body and a lifting beam. The attachment body is capable of being attached to the adhesive end of a battery body 3 in a first direction F1, and the lifting beam is fixedly disposed on the side of the attachment body opposite to the battery body 3. Both the attachment body and the lifting beam are made of silk-coated coated paper.

[0040] The protective film tape provided according to the above technical features, on the one hand, is attached to the adhesive end of the battery body 3 by means of an adhesive body, and the lifting beam set on the side of the adhesive body opposite to the battery body 3 makes it easy for the operator to pick up and place the battery body 3; on the other hand, both the adhesive body and the lifting beam are made of coated paper, wherein the coated paper (Magno Satin) is a coated art paper produced in Germany, which has a certain degree of water resistance, appearance and gloss. It can not only ensure the physical properties of the protective film tape such as water resistance, insulation, load-bearing capacity, tensile strength, etc., to meet the requirements of the protective film tape to lift and place the battery and to meet the basic function of battery replacement, but also the coated paper can comply with the Packaging and Waste Directive 94 / 62 / EC (Article 11) (i.e., coated paper is fully recyclable), effectively improving the recyclability, biodegradability and aesthetics of the protective film tape.

[0041] Preferably, the weight specification of the above-mentioned silk-coated paper can be 90g / ㎡ to 400g / ㎡, so as to further ensure the load-bearing capacity, tensile strength and other mechanical properties of the protective film tape, so as to meet the requirements of the protective film tape to lift and place the battery and to meet the basic function of replacing the battery.

[0042] Preferably, the thickness of the silk-coated paper can be 74μm to 412μm to further ensure the load-bearing capacity, tensile strength and other mechanical properties of the protective film tape, so as to meet the requirements of the protective film tape to lift and place the battery and to meet the basic function of replacing the battery.

[0043] Preferably, the surface of the above-mentioned silk-coated paper can be provided with screen printing. In other words, the screen printing can be understood as the traces formed on the surface of the silk-coated paper after a wire drawing process, so that the silk-coated paper can adapt to UV ink, thereby facilitating the printing of text on the surface of the protective film tape.

[0044] like Figures 1 to 4 As shown in the figure, F1 can be an example of the first direction F1 described above. Two intersecting directions on a plane perpendicular to the first direction F1 are defined as the second direction F2 and the third direction F3, respectively. F2 shown in the figure can be an example of the second direction F2, and F3 shown in the figure can be an example of the third direction F3. Preferably, the second direction F2 can be the extension direction of the adhesive end. Preferably, the third direction F3 can be perpendicular to the second direction F2 to facilitate application to examples where the battery body 3 is rectangular.

[0045] In an embodiment, preferably, such as Figures 1 to 3As shown, the aforementioned adhesive body may include a cover portion 10, which covers the surface of the battery body 3. An adhesive layer is applied to the side of the cover portion 10 facing the battery body 3 for connecting the cover portion 10 to the adhesive end.

[0046] Preferably, such as Figures 1 to 4 As shown, the aforementioned adhesive body may further include a tearing handle 11, which is disposed on the side of the cover portion 10 in the second direction F2 and connected to the cover portion 10. The tearing handle 11 extends along the second direction F2, and at least a portion of the tearing handle 11 extends beyond the battery body 3 in the second direction F2. On the one hand, it is convenient to take the protective film tape by tearing the handle 11, thereby preventing the operator from accidentally touching the adhesive layer of the cover portion 10 and affecting the adhesive layer's adhesion; on the other hand, it is convenient to tear the protective film tape off the battery body 3 by tearing the handle 11, facilitating the removal operation of the protective film tape.

[0047] Preferably, such as Figures 1 to 4 As shown, there can be two tearing handles 11. The two tearing handles 11 are respectively disposed on both sides of the cover portion 10 in the second direction F2, and the two tearing handles 11 are respectively close to the two ends of the cover portion 10 in the third direction F3. In this way, the two tearing handles 11 can be located at the two ends of the diagonal of the cover portion 10, so that the operator can use the two tearing handles 11 to flatten the adhesive body, thereby facilitating the picking and applying of the protective film tape.

[0048] Preferably, such as Figure 1 and Figure 4 As shown, a flexible circuit board connector 31 is provided at one end of the battery body 3 on the third-direction F3. It should be noted that the flexible circuit board connector 31 can be understood as a connector of the flexible circuit board of the battery body 3. Usually, the flexible circuit board connector 31 protrudes relative to the cell assembly on the third-direction F3 so that the flexible circuit board connector 31 can be plugged into external electrical equipment.

[0049] Preferably, such as Figures 1 to 4 As shown, the above-mentioned attachment body may also include a shielding part 12, which is connected to one end of the covering part 10 in the third direction F3. In the first direction F1, the shielding part 12 can completely cover the flexible board connection part 31 to improve the neatness and aesthetics of the battery product.

[0050] Preferably, the covering part 10, the tearing part 11, and the shielding part 12 can be an integrally connected structure. In other words, the covering part 10, the tearing part 11, and the shielding part 12 are formed by cutting from the same piece of silk coated paper.

[0051] It should be noted that neither the tearing part 11 nor the shielding part 12 is coated with the aforementioned adhesive layer on the side facing the battery body 3, so as to avoid the tearing part 11 and the shielding part 12 from sticking to other structures.

[0052] Preferably, as not shown in the figure, the adhesive end of the battery body 3 may be provided with an information label to display the parameter information, production information and product logo of the battery body 3.

[0053] Correspondingly, such as Figures 1 to 3 As shown, the aforementioned adhesive body may be provided with a viewing window 13. When the adhesive body is attached to the adhesive end, the aforementioned information label can be exposed by the viewing window 13.

[0054] Preferably, the viewing window 13 can be a hollow structure that penetrates the cover portion 10 along the first direction F1, so as to facilitate the discharge of gas between the attaching body and the battery body 3 during the attachment process, thereby improving the attachment stability of the cover portion 10.

[0055] In an embodiment, such as Figures 1 to 3 As shown, the lifting beam may include a first lifting ring 21 and a second lifting ring 22 spaced apart along the second direction F2, so as to enable the operator to hold the protective film tape with both hands, thereby ensuring the stability of the battery body 3.

[0056] Preferably, such as Figures 1 to 3 As shown, the first lifting ring 21 and the second lifting ring 22 are symmetrically arranged about the centerline of the adhesive end in the second direction F2 to ensure the uniform distribution of the lifting force applied by the operator to the battery body 3, so as to further improve the stability of lifting the battery body 3.

[0057] It should be noted that the above-mentioned lifting beam is made of silk-coated paper, which can be understood as both the first lifting ring 21 and the second lifting ring 22 being paper strip rings made of silk-coated paper.

[0058] Preferably, such as Figure 1 As shown, the paper strip loop can be a ring structure formed by folding a paper strip in half and overlapping the two ends of the folded paper strip. Both the overlapping portions of the paper strip and the ring structure can be fitted to the covering portion 10 to achieve connection between the paper strip loop and the covering portion 10. This effectively increases the connection area between the paper strip loop and the covering portion 10, improving the connection stability of the paper strip loop. However, it is not limited to this; as long as a paper strip loop structure can be formed, the paper strip loop can also be in other forms.

[0059] However, it is not limited to this. As long as the battery body 3 can be lifted, the above-mentioned lifting beam structure is not limited to the form of the first lifting ring 21 and the second lifting ring 22. For example, the lifting beam structure can be a lifting strap extending in a predetermined direction, with both ends of the lifting strap connected to the cover portion 10 in the predetermined direction. The predetermined direction can be the second direction F2, the third direction F3, or other directions in a plane perpendicular to the first direction F1.

[0060] The second aspect of this application also provides a battery, including the battery body 3 described above and the protective film tape described in any of the above embodiments, and thus has all the beneficial technical effects of the protective film tape, which will not be repeated here.

[0061] Preferably, the battery body 3 may include a cell assembly, a flexible circuit board, and the flexible circuit board connection portion 31. The flexible circuit board extends along the third direction F3. One end of the flexible circuit board is electrically connected to the cell assembly, and the other end of the flexible circuit board is connected to the flexible circuit board connection portion 31. In the third direction F3, the flexible circuit board connection portion 31 protrudes relative to the cell assembly to facilitate the connection of the flexible circuit board connection portion 31 with external electrical equipment.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
