EV Battery Thermal Protection: Why Aerogel Is Everywhere
How thin aerogel barriers slow heat spread between battery cells.
· 3 min read
Key takeaways
- Aerogel insulates in very thin layers.
- Used between cells to slow thermal propagation.
- Also useful for DIY battery and enclosure projects.
The problem
If one cell overheats, heat can spread to neighbours. Barriers buy time.
Why aerogel
Very low thermal conductivity in a thin, flexible blanket.
Pro tip: Wear a mask when cutting aerogel.
Lightweight enclosures
Carbon fiber panels combined with insulation create light, rigid enclosures.
