[0002] Battery tags are a type of label material used to mark or decorate batteries. In practical applications, battery tags often produce abnormal noises due to factors such as probabilistic pressing of the battery, expansion or contraction of the battery tag, or vibration and friction at the battery mounting location, which in turn affects the user experience of the battery. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] The battery tag provided in this application divides the existing substrate layer into a first substrate layer and a second substrate layer, and sets a noise-reducing and flame-retardant layer between the first substrate layer and the second substrate layer. This not only effectively reduces the stiffness of the battery tag, thereby reducing the probability of the battery tag making abnormal noises, but also, through the structure of the noise-reducing and flame-retardant layer sandwiched between the first substrate layer and the second substrate layer, the ink printing layer and the adhesive layer are in contact with the first substrate layer and the second substrate layer respectively, thereby effectively reducing the impact of the noise-reducing and flame-retardant layer on the structure of the battery tag and ensuring the stability of each layer of the battery tag.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] The following reference Figure 1 This application describes a battery label and battery according to some embodiments.

[0029] See Figure 1 As shown, an embodiment of the first aspect of this application provides a battery tag, which includes an ink printing layer 4, a first substrate layer 1, a second substrate layer 2, a noise-reducing and flame-retardant layer 3, and an adhesive layer 5. Specifically, the noise-reducing and flame-retardant layer 3 is laid between the first substrate layer 1 and the second substrate layer 2, the ink printing layer 4 is laid on the side of the first substrate layer 1 opposite to the noise-reducing and flame-retardant layer 3, and the adhesive layer 5 is attached to the side of the second substrate layer 2 opposite to the noise-reducing and flame-retardant layer 3.

[0030] According to the battery tag provided by the above technical features, by dividing the existing substrate layer into a first substrate layer 1 and a second substrate layer 2, and setting a noise-reducing and flame-retardant layer 3 between the first substrate layer 1 and the second substrate layer 2, the stiffness of the battery tag is not only effectively reduced, thereby reducing the probability of the battery tag producing abnormal noise; moreover, by using the structure of the first substrate layer 1 and the second substrate layer 2 to sandwich the noise-reducing and flame-retardant layer 3, the ink printing layer 4 and the adhesive layer 5 are in contact with the first substrate layer 1 and the second substrate layer 2 respectively, thereby effectively reducing the impact of the noise-reducing and flame-retardant layer 3 on the structure of the battery tag and ensuring the stability of each layer of the battery tag.

[0031] Preferably, the first substrate layer 1 is a PET coating; and / or, the second substrate layer 2 is a PET (Polyethylene terephthalate) coating, that is, at least one of the first substrate layer 1 and the second substrate layer 2 is a PET coating to ensure the waterproofness and durability of the battery label. However, it is not limited to this, the first substrate layer 1 and the second substrate layer 2 can also be other substrates, such as paper, PEF (Poly(ethylene terephthalate-1,4-cyclohexanedimethylene terephthalate), PI (Polyimide), PLA (Polylactic Acid), PHA (Polyhydroxyalkanoates), PBS (Poly(butylene succinate)), etc.

[0032] Preferably, such as Figure 1 As shown, the thickness t1 of the first substrate layer 1 satisfies: 1μm≤t1≤20μm. For example, t1 can be equal to 1μm, 2μm, 3μm, 4μm, 5μm, 6μm, 7μm, 8μm, 9μm, 10μm, 11μm, 12μm, 13μm, 14μm, 15μm, 16μm, 17μm, 18μm, 19μm, 20μm, etc.

[0033] Similarly, such as Figure 1 As shown, the thickness t2 of the second substrate layer 2 satisfies: 1μm≤t2≤20μm. For example, t2 can be equal to 1μm, 2μm, 3μm, 4μm, 5μm, 6μm, 7μm, 8μm, 9μm, 10μm, 11μm, 12μm, 13μm, 14μm, 15μm, 16μm, 17μm, 18μm, 19μm, 20μm, etc.

[0034] It should be noted that the thickness of the substrate for label paper today is typically in the range of 20μm to 40μm. According to the formula for calculating stiffness: Stiffness = (ET...) 3 / 12)×(B / L2). Where: E is the elastic modulus: this is an inherent property of the material, representing the degree of elastic response of the material under stress. The larger the elastic modulus, the smaller the deformation of the material under the same stress. The unit is Newtons per square meter (N / m²). 2 T represents the sample thickness: This is the physical thickness of the material sample, measured in millimeters (mm). The cube of the thickness is considered in the calculation, indicating that stiffness is proportional to the cube of the thickness. B represents the sample width: This is the width of the material sample, also measured in millimeters (mm). Width is proportional to stiffness; that is, the greater the width, the higher the stiffness. Therefore, by setting the thickness t1 of the first substrate layer 1 and the thickness t2 of the second substrate layer 2 to half the thickness of the existing label paper substrate, the stiffness of the battery label can be further reduced, thereby further reducing the probability of the battery label making abnormal noises.

[0035] Preferably, the noise-reducing and flame-retardant layer 3 can be a water-based damping material to utilize its vibration reduction, noise reduction, heat insulation, sound insulation, and low cost. However, it is not limited to this. The noise-reducing and flame-retardant layer 3 is not limited to the water-based damping material. As long as it can reduce the stiffness of the battery tag, the noise-reducing and flame-retardant layer 3 can also be other flexible flame-retardant materials. For example, the noise-reducing and flame-retardant layer 3 can also be a flexible polyurethane flame-retardant material; another example is that the noise-reducing and flame-retardant layer 3 can also be a flexible polyolefin flame-retardant material; yet another example is that the noise-reducing and flame-retardant layer 3 can also be a flexible flame-retardant composite phase change material, that is, a composite material formed by combining a phase change material (such as paraffin) with a flame retardant (such as expanded graphite or ammonium polyphosphate); yet another example is that the noise-reducing and flame-retardant layer 3 can also be a silicone rubber flame-retardant material.

[0036] It should be noted that the water-based damping material is existing technology in this field (see the coatings described in Chinese patent documents CN111909584A or CN111087865A), and will not be described further here.

[0037] Preferably, such as Figure 1As shown, the thickness t3 of the noise-reducing and flame-retardant layer 3 can satisfy: 1μm≤t3≤30μm. For example, t3 can be equal to 1μm, 2μm, 3μm, 4μm, 5μm, 6μm, 7μm, 8μm, 9μm, 10μm, 11μm, 12μm, 13μm, 14μm, 15μm, 16μm, 17μm, 18μm, 19μm, 20μm, 21μm, 22μm, 23μm, 24μm, 25μm, 26μm, 27μm, 28μm, 29μm, 30μm, etc., to balance the influence of the noise-reducing and flame-retardant layer 3 on the stiffness of the battery label and the stability of the battery label structure (i.e., t3≥15μm can ensure the effectiveness of the influence of the noise-reducing and flame-retardant layer 3 on the stiffness of the battery label; t3≤30μm can ensure the stability of the battery label structure).

[0038] Optionally, the adhesive layer 5 can be a double-sided adhesive layer, an adhesive coating, or other adhesive layer that can attach the battery label to the surface of the battery.

[0039] Preferably, such as Figure 1 As shown, the thickness t4 of the adhesive layer 5 can satisfy: 1μm≤t4≤30μm. For example, t4 can be equal to 1μm, 2μm, 3μm, 4μm, 5μm, 6μm, 7μm, 8μm, 9μm, 10μm, 11μm, 12μm, 13μm, 14μm, 15μm, 16μm, 17μm, 18μm, 19μm, 20μm, 21μm, 22μm, 23μm, 24μm, 25μm, 26μm, 27μm, 28μm, 29μm, 30μm, etc., to ensure the adhesive stability of the adhesive layer 5.

[0040] Preferably, such as Figure 1 As shown, the thickness t5 of the ink printing layer 4 can satisfy: 1μm≤t4≤3μm. For example, t4 can be equal to 1μm, 1.5μm, 2μm, 2.5μm, 3μm, etc. This not only ensures the clarity of the ink printing layer 4, but also avoids the ink printing layer 4 being too thick or unevenly distributed, which may lead to local stress concentration during folding or rolling, thereby causing abnormal noise.

[0041] Preferably, such as Figure 1 As shown, the battery label may also include a transparent protective layer 6, which covers the surface of the ink printing layer 4 to protect the ink printing layer 4 and prevent the ink printing layer 4 from being worn away during use, resulting in the loss of the label's markings.

[0042] Optionally, the aforementioned transparent protective layer 6 may be a matte oil coating, which is an existing coating in the art and will not be described in detail here.

[0043] However, it is not limited to this. The transparent protective layer 6 is not limited to the above-mentioned matte oil coating. The transparent protective layer 6 can also be a plastic film, a thermoplastic film, or other transparent protective film.

[0044] Preferably, such as Figure 1 As shown, the thickness t6 of the transparent protective layer 6 can satisfy: 1μm≤t6≤4μm. For example, t6 can be equal to 1μm, 2μm, 2.5μm, 3μm, 3.5μm, or 4μm. This ensures that t6≥2μm, effectively guaranteeing the protective and wear-resistant properties of the transparent protective layer 6. Ensuring that t6≤4μm effectively avoids uneven distribution of the transparent protective layer 6 due to excessive thickness, which could lead to local stress concentration during folding or rolling, thus causing abnormal noise.

[0045] An embodiment of the second aspect of this application also provides a battery including the battery tag described in any of the above embodiments, thus possessing all the beneficial technical effects of the battery tag, which will not be repeated here.

[0046] Alternatively, the battery can be a mobile phone battery, a laptop battery, or a battery for other electronic devices.

[0047] 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.
