These adhesives keep the cells firmly in place throughout the vehicle's lifespan. Adhesive technology plays a vital role in the assembly and performance of electric vehicle battery packs. From ensuring structural integrity to managing heat and enhancing safety, adhesives, and sealants contribute significantly to the success of EVs.
Plus, sealants that allow simple disassembly at the battery's end-of-life foster the reuse and recycling of EV battery components. In addition to performance, EV battery designers know that adhesives and sealants must work well in high-volume production.
Sealants are used in the assembly of the battery case enclosure. The main objective of the sealants is to protect the module from any moisture intrusion or chemical leakages, preventing the inside of the battery from exposure to the environment.
Dupont’s BETAMATE (5) and BETAFORCE (7) are part of a broad portfolio of adhesives for numerous EV applications. The next generation of EV batteries is witnessing the emergence of cell-to-pack designs. These designs integrate battery cells into the pack using thermal structural adhesives.
Specifically, adhesives and sealants have a critical role in EV battery durability, performance, and manufacturing. Understanding how these solutions work will help automotive designers innovate and meet the demand for EVs, which is expected to be more than 50% of global car sales by 2028.
Structural Bonding Structural adhesives for battery packs optimize housing integrity and crash performance. Henkel's solutions can be applied cost-efficiently by robot, and are suitable for both aluminum and multi-metal frames and structures.
