Abstract
A method for making a battery system includes applying fast-cure and slow-cure adhesives to interfaces between components. The fast-cure adhesive allows manipulation of the assembly during manufacturing while the slow-cure adhesive cures. The slow-cure adhesive provides desired strength and toughness as needed during use of the final assembly. The fast-cure adhesive and slow-cure adhesive have respective curing schedules. The fast-cure adhesive includes a moisture-curing adhesive or any other suitable adhesive curing on the order of seconds such as UV-activated or cyanoacrylate adhesives. The slow cure adhesive includes any suitable structural adhesive such as a two-part mix-cure epoxy or acrylic. The components adhered using the fast-cure adhesive and slow-cure adhesive include side wall sections, battery cells, mounting bracket, bus bars, or any other suitable components. The fast-cure and slow-cure adhesives are applied in any suitable pattern such as, for example, beads, dots, paths, non-intersecting paths, or any other suitable application shape.
