In their most recent collaboration, Henkel and Covestro developed a solution enabling the efficient fixation of cylindrical li-ion battery cells inside a plastic cell holder. The solution is based on a UV-curing adhesive from Henkel and a UV-transparent polycarbonate blend from Covestro.
The adhesives need to allow the manufacturing as well as the structural and crash-durable joining of the battery enclosure. Adhesives and sealants are used to seal the battery from external environments and protect the cells and electronic parts inside the battery.
Courtesy of Dupont. Some adhesives for battery assembly serve a multifunctional role, providing structural joining, thermal management, and support for dielectric isolation. Adhesives in this class offer thermal management and medium strength that supports the stiffness and mechanical performance of the battery pack.
On top of the thermal conductivity the adhesive further needs to show a good structural strength paired with a high elongation at break to maintain the mechanical structure over the lifetime of a battery also under load (e.g. vibration).
Adhesives and sealants are used to seal the battery from external environments and protect the cells and electronic parts inside the battery. For the thermal management of the battery, thermally conductive adhesives and thermal interface materials are needed to allow for a proper thermal connection of parts and cells.
The crash-durable adhesives with a high modulus and high strength allow the construction of battery enclosures with an excellent structural stability and stiffness, so that the battery is also protected in case of a crash. An additional advantage is that the adhesive is not only bonding the substrates together but is also sealing the enclosure.
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.

The battery pack in an EV is made up of a series of modules that are in turn made up from individual lithium-ion cells that are connected in series and parallel. The grouping of cells together into vibration proof and weather tight modules requires a variety of adhesives, sealants, gaskets, and thermal materials.
