Keschuang and Henkel work together to promote the development of electric transportation

With the continuous development of vehicle electrification, the battery pack of the core components of electric vehicles has become a hot topic in the field of electric vehicles Although the design of the battery system varies from manufacturer to manufacturer, all automotive battery technologies share a common performance goal, which is longer life, safer operation, lower total cost and stronger reliability For this reason, covestro and Henkel have jointly developed an innovative solution By combining Henkel's UV curing adhesive with covestro's UV penetrating polycarbonate alloy, the cylindrical lithium-ion battery can be efficiently fixed in the plastic battery base Vehicle manufacturers are considering large-scale, high-efficiency and low-cost lithium-ion battery components as a prerequisite for competition to cope with the severe pressure of cost reduction of electric vehicles The adhesive of Loctite AA 3963 battery module of Henkel and the high ultraviolet light penetrating polycarbonate alloy of baybrand? Of kostron meet the requirements of batch automatic dispensing technology, and the adhesive can be flexible and fast curing In addition, the specially developed acrylic structural adhesive is suitable for battery bases made of special flame-retardant plastics This kind of structural adhesive and base material have strong adhesive force, long opening time and short curing time, and have good production adaptability Frank kerstan, head of Henkel's European electric vehicle business, explained: "it is critical to be able to complete mass production with flexible processes in a short period of time Loctite is an on-demand curing single component adhesive, which is approved by the vehicle manufacturer to fix the cylindrical lithium-ion battery into the carrier After high-speed glue injection, the glue can endure long opening time, improve the adaptability of the whole process, and better deal with unexpected production interruption After all the cells are put into the battery base and the structural adhesive is injected, the UV curing process takes less than 5 seconds to achieve ultra fast curing " This is the main advantage different from traditional manufacturing In traditional manufacturing process, curing may take several minutes to several hours, so additional parts storage space is required The battery base is made of Coriolis benlan? Fr3040 EV polycarbonate + ABS alloy When the thickness of the plastic is only 1 mm, it can reach the UL94V0 flame retardant grade, and has good transmission to the ultraviolet light with wavelength of more than 380nm Steven daelemans, manager of electric transportation market development, polycarbonate business department, Cisco, said: "this material enables us to manufacture parts with stable size, which is necessary for automatic bulk packaging Combined with the rapid curing ability of Loctite adhesive, this material combination provides an innovative method for large-scale modular production of cylindrical lithium-ion batteries " Loctite is a registered trademark of Henkel and / or its subsidiaries in Germany and elsewhere.
