The adhesive tapes used in EV (electric vehicle) battery packs are designed with the core objective of meeting the comprehensive requirements of battery modules in terms of safety, durability and sealing. As battery modules integrate high-energy-density lithium-ion cells and operate in environments that may involve high temperatures, vibrations, humidity, and chemical corrosion, these tapes serve not only as simple bonding materials but also as critical components for structural reinforcement, electrical insulation, thermal management, and environmental protection.

In terms of safety, the tapes must provide excellent flame retardancy and insulation to prevent risks such as short circuits and thermal runaway. Sealing performance ensures that the battery pack achieves effective water and dust protection, meeting stringent IP rating requirements. In terms of manufacturing efficiency, tapes help simplify assembly, minimize the use of parts and mechanical fasteners, speed up production, and reduce total weight.

In summary, tapes used in EV battery packs are high-performance materials that ensure the sustained performance and longevity of electric vehicles.
