EV Battery thermal management
Thermally conductive tapes and films, thermal runaway protection materials and venting solutions designed to address all thermal challenges in EV battery packs.
Thermal management is critical to battery performance, safety and longevity. Adhex thermally conductive tapes and films ensure optimal heat transfer between cells, modules and cooling plates — while maintaining electrical insulation.
In the event of thermal runaway, our UL-94 rated protection materials slow down heat and flame propagation between cells, buying critical time for passenger safety.
Combined with our venting solutions — which allow controlled gas evacuation while preventing liquid and dust ingress — they form a comprehensive thermal safety system for EV battery packs.
