Kapton High Temperature Tape for Battery Fixing and Protection Features

High temperature resistance: In the use of batteries and the process of charging and discharging, heat may be generated, especially in some high rate charging and discharging or high temperature environment of the battery, Kapton high temperature tape long-term working temperature up to 260 ℃, short-term can be processed below 300 ℃, can maintain good performance in high temperature environments, will not be de-adhesive, residual adhesive, and deformation of the substrate and so on, to ensure that the fixing and protecting effect of the battery will not be affected. Ensure the fixation and protection of the battery will not be affected.
Electrical insulation: excellent dielectric properties, good electrical insulation can prevent short circuit and leakage between the positive and negative poles of the battery or between the battery and other parts, improve the safety and stability of the battery, especially important for lithium batteries and other batteries with high safety requirements.
Chemical stability: good resistance to acid, alkali, salt and other chemicals, can be used normally in a certain degree of chemical corrosion environment. In the process of battery use, even if there is electrolyte leakage and other situations, Kapton high temperature tape can maintain its performance stability, will not be corroded or damaged, so as to continue to play a fixed and protective role.
Good mechanical properties: high mechanical strength, high tensile strength, good flexibility and ductility, can be tightly adhered to the battery surface and various shapes of the battery, including flat, curved surfaces and complex irregular surfaces, to adapt to different shapes and sizes of the battery fixing needs, and is not easy to fracture or breakage in the process of use.
No residual adhesive: using imported silicone pressure-sensitive adhesive as adhesive, no residual adhesive is left after the tape is torn off, which avoids contamination and damage to the surface of the battery, does not affect the appearance and performance of the battery, and also facilitates the operation of the tape when it needs to be replaced or the maintenance of the battery.

Kapton High Temperature Tape for Battery Fixing and Protection Applications

Lithium battery manufacturing strapping: In the production process of lithium batteries, Kapton high-temperature tape can be used for strapping battery cells and battery protection plates and other components to ensure the safety and stability of the battery in the assembly and use process.
For example, when assembling multiple battery cells into a battery pack, the use of Kapton high-temperature tape can firmly fix the battery cells together, preventing the battery cells from loosening or shifting in the process of use, and at the same time, its high-temperature resistance can also prevent the battery from charging and discharging process of the heat generated by the adhesion of the tape and the performance of the impact.
Battery Positive and Negative Fixing: Kapton high temperature adhesive tape can be used for fixing the positive and negative terminals of lithium batteries to ensure that the positive and negative terminals are in a stable position inside the battery, and to prevent the positive and negative terminals from having poor contact or short circuit due to vibration, impact and other reasons during the use of the battery. In addition, the insulating properties of the tape can also avoid accidental electrical connection between the positive and negative electrodes, improving the safety and reliability of the battery.
Battery encapsulation protection: For some batteries that need to be sealed, such as flexible pack batteries, Kapton high temperature tape can provide good sealing performance. It can be tightly adhered to the encapsulated edge of the battery to prevent outside air, moisture or other impurities from entering the battery, affecting the performance and life of the battery. At the same time, the tape's high temperature resistance also ensures that the sealing effect is still good under the high temperature environment of the battery.
Battery module fixing and isolation: In the assembly of battery module, Kapton high temperature tape can be used to fix each cell in the battery module, and play the role of isolation, to prevent mutual extrusion, friction or short-circuit between the battery cells. Its good flexibility and adhesion can make the tape adapt to different shapes and sizes of battery modules, ensuring the overall stability and safety of the battery module.
