Thermally conductive adhesive brand for new energy batteries

Does Henkel offer a thermally conductive adhesive for EV battery systems?

Therefore, Henkel has extended its broad portfolio of solutions for EV battery systems with a first-of-its-kind injectable thermally conductive adhesive. The new adhesive – Loctite TLB 9300 APSi – provides both structural bonding, as well as thermal conductivity in the battery system.

Why are thermally conductive adhesives important for EV battery packs?

Thermally conductive adhesives play a crucial role in electric vehicle (EV) battery packs by addressing the critical need for efficient heat management. EV battery packs generate significant heat during operation, which can negatively impact their performance, lifespan, and safety.

What are thermally conductive adhesives?

Thermally conductive adhesives help mitigate these issues by providing a reliable bond between battery cells and heat dissipation components, such as heat sinks or other thermal interface materials. These adhesives facilitate the transfer of heat away from the cells, allowing for effective dissipation and maintaining optimal operating temperatures.

What are thermally conductive adhesives (TCAs)?

Thermally Conductive Adhesives (TCAs) are key Thermal Interface Material (TIMs) used in Cell-to-Pack configurations, providing structural bonding and thermal conductivity. In this configuration TCAs are dispensed on the inside of the battery case and cells are then stacked in the case to create the battery pack structure.

Are EV batteries thermally conductive?

“Thermal management in EV batteries is still one of the biggest challenges for electrified mobility. New designs targeting higher energy densities in battery packs bring along the requirement for multifunctional thermally conductive adhesives instead of classical thermal gap fillers.

Can debondable adhesives be used in EV batteries?

Functional materials such as debondable structural adhesives and debondable thermally conductive adhesives will enable OEMs and battery manufacturers to include debond-on-demand solutions into EV batteries, thereby extending the maximum lifetime of batteries and easing the dismantling process for EOL applications.
