Digital Battery Assembly Application of DeepMaterial Adhesive Products

As vehicle 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, common performance goals for all automotive battery technologies are longer life, operational safety, cost efficiency, and reliability. In their recent collaboration, Deepmaterial and Covestro have developed a solution that enables the efficient retention of cylindrical lithium-ion batteries within a plastic battery holder. The solution is based on a UV-curable adhesive from Deepmaterial and a UV-transparent polycarbonate blend from Covestro.

Large-scale and cost-effective lithium-ion battery assembly is a prerequisite for every automotive OEM as consumers strongly push to lower EV prices. Therefore, Deepmaterial's Loctite AA 3963 battery assembly adhesive and Covestro's UV-transparent polycarbonate blend Bayblend® were developed to be compatible with high-volume automated dispensing technology and offer a flexible and fast curing mechanism. The acrylic adhesive is formulated for use with battery holders, which are made of a special flame retardant plastic. It provides strong adhesion to substrate materials and provides production flexibility through long open times and short cure cycles.
