Battery Aerogel Thermal Barrier Pads
Lightweight aerogel-based thermal barrier materials designed for evaluation in EV battery and energy storage assemblies.
- ThicknessGrade-dependent
- 0.3-5 mm
- Material conductivity
- ≤0.025 W/(m·K) at 25 °C
- Density
- 180-300 kg/m³
Overview
Thin aerogel-based pads are intended for engineering evaluation in constrained battery, energy-storage and transport assemblies. Final performance depends on the cell, pack layout, clamping load and validation method.
Material selection should be made against the specific thermal, electrical, mechanical and compliance requirements of the finished assembly.
- Fit and compression
- Confirm cell format, available gap, cut pattern, fixation and compression in the intended assembly.
- Electrical and thermal validation
- Check electrical isolation, heat propagation, aging and mechanical durability in the pack-level test plan.
Typical applications: Battery modules, Energy storage systems, Cell spacing, Pack-level thermal barriers.

Handling and selection limits
Handling / storage
- Confirm cut pattern, compression, edge treatment and fixation with a representative assembly trial.
- Use the pack-level validation plan to assess electrical isolation, thermal propagation, ageing and mechanical durability.
Selection limits
- No UL 94, pack fire, thermal-runaway or vehicle compliance claim is made on this page without the applicable report and assembly conditions.
- Do not infer pack-level results from a material-only thermal conductivity value.

Product FAQ
Is this a validated battery thermal-runaway solution?
It is a material for evaluation. Pack-level validation, including the selected test method and construction, remains the responsibility of the project team.
How is thickness selected?
Select it against available space, target thermal path, compression condition and the project validation plan.
