Arkema’s new thermal battery runaway material concept

Arkema, a specialty materials company, has announced its Foranext® Gaseous Thermal Barrier (GTB) line, designed to prevent battery thermal runaway propagation in EVs.

Foranext® GTB is a material that can be incorporated into immersion cooling fluid technology to combat thermal runaway propagation. GTB is activated when a battery cell reaches unusually high temperatures, forming a gaseous barrier around the cell and isolating it from the rest of the battery. While gases produced during the thermal runaway process can ignite outside the vehicle, the addition of GTB to the vented gases reduces the likelihood of ignition.

Arkema mentioned they are the first company to propose a gaseous alternative to a solid thermal barrier. This combines the excellent heat dissipation performance of immersion cooling with the exceptional thermal insulation provided by Foranext® GTB.
