Making lithium-ion
battery systems safer.

The industry leader in passive thermal runaway containment and
propagation prevention. LithiumPrevent is proven effective through
internal testing, independent testing, and evaluations at NASA,
the FAA and DNV.


A passive fire safety system that delivers reliable, cost-effective, high performance passive fire propagation protection. We consistently meet the thermal runaway propagation standard for OEM’s to supply safer lithium-ion battery systems.

LithiumPrevent’s proprietary intumescent technology is injection molded or extruded to form fire-resistant battery pack components. The technology, combined with innovative designs and our team’s expertise, delivers superior thermal runaway containment and propagation prevention for OEM battery system.


Flexible by design, our engineers can custom-build cost-effective solutions that are QA tested and optimized to meet individual OEM specifications for smooth system integration. Our team of experts has consistently succeeded in meeting fire safety standards and will work closely with your team to ensure your system achieves whatever standard is required, including UL 9540A.

Independent Testing & Evaluation


“The results clearly form a cohesive picture as to the viability of a safe packaging solution for containment of a thermal runaway fire based on intumescent fire resistant polymer composites for operational use, transportation and storage of lithium ion cobalt batteries.”


“It was shown that insulation materials can prevent the probable propagation of thermal runaway in modules constructed with the prismatic cells.”


“As a last line of defense these materials have demonstrated significant potential to limit or halt propagation.”
