Covestro and Henko Strong force driven the development of electric transportation to provide adhesive solutions for efficient lithium-ion battery packaging

With the continuous development of automobile electrification, powerful lithium-ion batteries have become a central topic in the field of electric vehiclesAlthough battery systems are designed to vary from manufacturer to manufacturer, all automotive battery technologies share common performance goals of longer life, safer operation, lower cost, and greater reliabilityTo this end, Covestro and Henko have developed a solution that efficiently secures cylindrical lithium-ion batteries in plastic battery holders by combining Henco's UV curing adhesive with Covestro's high UV transmission through polycarbonate alloysautomakers are viewing large-scale, high-efficiency and low-cost lithium-ion battery components as a prerequisite for competition to cope with the severe pressure to cut prices for electric vehiclesThe High UV Adhesive slot trespass edgto of the Loctite AA3963 battery component and Covestro's high UV through polycarbonate alloy, Bayblend® ®, meets the requirements of high-volume automatic dispensing technology, and the adhesive is flexible and fast curingIn addition, professionally developed acrylic adhesives are suitable for battery holders made of special flame retardant plasticsThis adhesive has a strong adhesion to the substrate and has good production adaptability for long opening hours and short curing cyclesCovestro Baibenland ® materials and Henkolete adhesives to create cylindrical lithium-ion battery modules (Photo: Hencore)efficient and flexible production
explains Frank Kerstan, head of Henco's European electric vehicle business, "It is critical that large-scale production can be completed in a flexible process in a short period of time." Lotte is an on-demand curing of single-component adhesives, approved by the vehicle manufacturers, can be cylindrical lithium-ion batteries fixed to the carrierAfter high-speed dispensing, the material can tolerate long opening hours, improving the adaptability of the entire process to cope with unexpected production interruptionsAfter all batteries are placed in the battery holder and the adhesive injection is complete, the curing step is activated by UV rays and takes less than 5 seconds"This is a major advantage that differentiates it from traditional manufacturing, where curing can take from a few minutes to a few hours in a traditional manufacturing process, requiring additional parts storage space." thebattery holder is made of Covestro Bebenland ® FR3040EV polycarbonate and ABS alloyThe plastic is only 1 mm thick, the U.SUL company UL94 flame retardant V-0 grade, and the wavelength of more than 380 nanometers of ultraviolet rays have good transmission"This material allows us to create a stable size part, which is necessary for automated batch packaging," said Steven Daelemans, electric transportation market development manager for the Covestro Baibenland ® materials and Henkolete adhesives to create cylindrical lithium-ion battery modules (Photo: Hencore) Covestro polycarbonate business unit Combined with the fast curing capability of Lotte adhesives, this combination of materials provides an innovative approach to the production of large-scale cylindrical lithium-ion battery modules "
