Analyze the temperature resistance requirements of lithium battery tape

The maximum operating temperature of lithium battery tape does not exceed 110°C. Once the temperature exceeds 110°C for a long time, the micropores of the lithium battery separator will be closed, causing obstacles to electron transfer. In order to improve the high temperature resistance of high-strength adhesives, chemical cross-linking methods are usually used to make the polymer have a porous structure and comprehensively improve its heat resistance. Therefore, under normal circumstances, the high temperature resistance of the lithium battery belt should not exceed 110°C, but in order to guard against unforeseen circumstances, the performance of the lithium battery belt should actually exceed the specified characteristics. Lithium battery tape is based on polyimide film, coated with high-performance silicone pressure-sensitive adhesive on one side. There are two types of materials, one-sided fluorine plastic release material composite or non-composite. After the high-tech surface grafting solution, the combined high-performance tape is widely used, especially in the field of thermal sealing of soft-packaged lithium batteries, with excellent performance. Generally speaking, the temperature resistance of the tape in question refers to high temperature resistance, unless specified as low temperature resistance. The factors that affect the temperature resistance of lithium battery tapes mainly include two aspects: one is the temperature resistance of the adhesive, and the other is the temperature resistance of the substrate. The high temperature tape has good thermal stability, can work at 200℃ for a long time, and can withstand high temperature of 260℃ in a short time. Soft and tear resistant, strong adhesion, not easy to deform, suitable for pasting protection on the surface of various profiles. There is no glue residue, and no glue residue will be left when the tape is torn off after a long period of high temperature curing. High mechanical strength, suitable for tight and firm coil wrapping. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
