About Battery Firebreak
Battery Firebreak is an independent, vendor-neutral reference on battery thermal-runaway barriers, fire-protection materials and safety test standards.
Why this site exists
Engineers choosing materials to stop a single failing cell from setting off its neighbours face scattered information: supplier brochures that use different test conditions, standards that are expensive to read in full, and regulations that change quickly in China, the US, the EU and Australia. This site puts the comparable facts in one place and links every figure to its source.
What we cover
- Materials data: typical properties of aerogel, mica, ceramic-fibre, intumescent and other barrier materials, with sources.
- Standards: plain-language summaries of thermal-runaway and propagation requirements for EV batteries and energy storage.
- Guides: how thermal propagation works, how barrier materials are selected and how products are tested.
Who writes it
Content is written and checked by materials scientists with a research background in functional materials and computational materials science. We do not sell barrier materials or testing services. See the editorial policy and disclosures.
