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.
