Redefining Battery Safety While Maximizing Energy Density

Our breakthrough technology, GORE Battery Insulation, helps protect battery installation from thermal runaway propagation while enabling higher energy density.

Reliable When Others Fail

Traditional, compressible thermal barrier layers like aerogel, cork or silicone foam compress under load (due to battery swelling). This causes them to lose thermal resistance and increase the risk of failure.

GORE Battery Insulation is Different

- Low compressibility to maintain thermal resistance
- Ultra-low thermal conductivity
- Exceptional mechanical stability


GORE Battery Insulation enables compact, high-capacity battery designs without sacrificing safety.

How Does it Work?

When used in a hybrid configuration, this new ultra-thin, non-particulating material helps accommodate battery swelling while optimizing costs by alternating with industry-standard compliant materials. GORE Battery Insulation effectively isolates thermal propagation, preventing catastrophic failure of the entire module.

Comparison infographic showing GORE Battery Insulation versus an Aerogel Alternative. On the left, the GORE material is labeled “2.0 mm thickness” with a fibrous structure, while the aerogel is labeled “4.0 mm thickness” with a porous texture. In the middle column, GORE insulation compresses to about 2.0 mm in a battery module, while aerogel compresses more to 3.0 mm. On the right, under high heat and pressure, the GORE insulation shows higher thermal resistance, keeping flames contained within one battery

The structure sits about 1 mm high before activation and spans less than 35 mm. It is mounted on a housing surface over a battery enclosure. At around 200 mbar of internal pressure, the activation layer enables venting from the battery enclosure through the breathable vent layer.
