As automotive electrification continues to evolve, powerful lithium-ion (li-ion) battery architectures are at the center of discussions around electric vehicles. While battery system designs vary by manufacturer, the joint performance objectives for all automotive battery technologies are longer lifetime, operational safety, cost efficiency and reliability. 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.
