Aerogels – often supplied for high temperature insulation as nonwoven blankets – have experienced steady market growth historically, reaching a market of just under US$450 million in 2022, according to a new report from IDTechEx.
Progress has been slower than expected largely due to competition with lower-cost incumbent insulation materials. The emergence of aerogels as a fire protection material for electric vehicle (EV) batteries provides a new and rapidly growing opportunity for the aerogel market. The IDTechEx report, Aerogels 2024-2034: Technologies, Markets and Players, predicts that EV batteries will account for over half of the aerogel market by 2025.
Thermal insulation
Aerogels are well known to exhibit excellent thermal insulation (15-20mW/m.K) making them ideal for EV batteries.
Typically, battery cells are cooled via a thermal management strategies like water cold plates and coolant channels. However, around these it can be beneficial to thermally insulate the cells from each other. This aids in keeping cells warm in cold conditions and prevents heat transfer between cells in the event of an overheating cell. Aerogels also have a very low density (
