The heat extracted using adhesive originates from electrical resistance in the battery’s electrodes, electrolyte, current collectors, busbars, and various interconnections. For this reason, thermal adhesives are used at several locations in battery modules, such as between individual cells, or between cells and cooling plates.
Courtesy of Dupont. Some adhesives for battery assembly serve a multifunctional role, providing structural joining, thermal management, and support for dielectric isolation. Adhesives in this class offer thermal management and medium strength that supports the stiffness and mechanical performance of the battery pack.
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.
Adhesives are used at several locations in battery modules to help dissipate heat, insulate electrical components, seal off against environmental damage, and create strong structural bonds. Here are common examples of where they are used:
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.
Advanced adhesives and sealants like those from DuPont can help advance sustainability. An essential contribution of adhesives to EV battery design is that they allow for greater simplicity. For example, adhesives help reduce or eliminate mechanical fasteners, reducing battery complexity.
