“Growing Use of Thermal Interface Adhesives for Battery Performance and Safety”
• Thermal interface adhesives are becoming critical in electric vehicle (EV) battery systems to ensure optimal thermal conductivity and stable operating temperatures during high load conditions
• These adhesives replace traditional thermal pads and gap fillers by offering a more consistent interface between battery cells and cooling plates, enhancing durability and performance
• Their role is especially vital in high-energy-density battery packs used in long-range EVs, where managing excess heat is essential for preventing degradation and thermal runaway
• Automakers are also turning to these adhesives to reduce reliance on mechanical fasteners, which adds to vehicle weight and complicates design in tight spaces
• As EVs transition to 800V architectures and ultra-fast charging capabilities, the thermal load on battery components increases, driving the adoption of these high-performance adhesives
• For instance, Tesla’s Model Y integrates thermally conductive adhesives in its battery module design to facilitate efficient heat dissipation, reduce component stress, and optimize battery lifespan
