EV aerogel heat shields
Back to Products
EV aerogel heat shields are used in separators in EV batteries and help to mitigate thermal runaway propagation. Aerogel-based solutions provide highest thermal management performance over the full lifecycle of the EV battery.
EV aerogel heat shield EAH
Application: Heat shield
The EV aerogel heat shield EAH is a passive aerogel-based cell-to-cell barrier for prismatic and pouch cell form factors. It contains an ultra-thin aerogel functional layer encapsulated in a polymer film.
