For this reason, thermal adhesives are used at several locations in battery modules, such as between individual cells, or between cells and cooling plates. Structural adhesives are used in EV battery packs to create bonds that can withstand various environmental conditions and mechanical loads.
Battery adhesives come under various forms, such as liquids, pastes, gels, tapes, and pads. The distinct types of adhesives offer different benefits: Acrylic-based adhesives are known for their ability to bond a broad range of raw metals, composites, and thermoplastics.
Small components: Adhesives are used to attach small components such as heat spreaders, thermal pads, and sensors. Depending on the attached components, adhesives can provide various benefits, such as better thermal conductivity or insulation. Battery adhesives come under various forms, such as liquids, pastes, gels, tapes, and pads.
Structural adhesives for battery packs optimize housing integrity and crash performance. Henkel's solutions can be applied cost-efficiently by robot, and are suitable for both aluminum and multi-metal frames and structures. Metal pretreatment technologies protect battery pack housing against corrosion.
By Catherine Veilleux on January 23, 2024 Batteries & EVs In EV battery manufacturing, adhesives are increasingly used to bond components. They are replacing mechanical fasteners as well various joining technologies. Unlike screws, bolts, and welding, structural adhesives provide a range of benefits beyond the bond.
They also offer easy material handling. Conductive coatings improve the charging and discharging performance of lithium-ion battery cells by reducing the electrical resistance between active material and aluminum foil. Battery assembly adhesives enable cost-efficient and fast assembly of prismatic, cylindrical or pouch cells.
