Aspen Aerogels

Aspen Aerogels developed PyroThin®, the world’s first aerogel cell-to-cell barrier engineered for pouch and prismatic battery cell applications. Utilizing Aspen’s proprietary Aerogel Technology Platform®, PyroThin delivers the ultimate thermal runaway propagation protection. PyroThin’s combined thermal and mechanical performance enables PyroThin to act as both a fire barrier and compression pad, in an ultrathin and lightweight format. When battery engineers choose PyroThin as part of their thermal runaway strategy, they can use thinner cell-to-cell barriers, fit more cells within modules, and decrease pack weight.
