Maximize Thermal Runaway Propagation Protection with PyroThin® Aerogel Cell Barriers

  • Mitigate or Stop Thermal Runaway Propagation

    PyroThin advanced thermal barriers have proven that thermal propagation can be stopped at a cell-to-cell level.

  • Meet Critical Safety Requirements

    PyroThin helps battery engineers satisfy and exceed China’s GB38031 and the United Nations’ ECE/TRANS/180/Add.20 standards.

  • Optimize Battery Pack Performance

    Major OEMs choose PyroThin because PyroThin can perform the mechanical function of a compression pad and the thermal role of a fire barrier.

  • Enable Next-Generation Cell Architecture

    PyroThin cell-to-cell barriers are ultrathin and lightweight, which supports maximum volumetric cell-to-pack ratio (VCPR).

PyroThin’s Proven Performance

In 2024, PyroThin won Automotive News PACE and Innovation Partnership Awards. The Innovation Partnership Award recognizes our extensive collaboration with General Motors as the thermal runaway solution for its Ultium battery platform.

Aspen Aerogels was also named 2022’s Overdrive Award Winner for Launch Excellence, as part of General Motors’ 30th Supplier of the Year Award. PyroThin’s proprietary technology and Aspen’s agile engineering support played a crucial role in GM’s thermal propagation strategy for their Ultium battery platform.

PyroThin C2C barriers are in volume production for major automotive OEMs in North America, Europe, and Asia.
