Advanced thermal runaway barriers

Extend battery cell life, optimise performance, and improve safety

Effective thermal runaway barriers are essential for optimising cell performance, longevity, and safety of battery packs.

Our OEM-approved thermal cell barriers are a breakthrough in anti-thermal propagation technology for prismatic, pouch, and cylindrical cells. The thermal runaway barriers address persistent industry challenges while reducing overall costs without compromising quality.

Developed at our IATF-certified facility in collaboration with leading automotive OEMs, our solution is used across electric vehicle ranges, providing a superior thermal propagation delay of over 20 minutes.

Advanced thermal runaway barriers for battery packs

Tecman Battery Application Diagram No Labels 640X812

Our ground-breaking thermal runaway barriers, known as Anti-thermal Propagation (ATP) Pads, incorporate innovative features designed to optimise both the performance and lifespan of the cell and improve the overall safety of the battery pack.

Available for prismatic, pouch, and cylindrical cells, our advanced thermal cell barriers prevent or delay thermal propagation from a thermal runaway event.

ATP Pads can be customised for specific requirements and manufactured using an industry-leading all-in-one process, eliminating third-party pre-conversion for efficient, high-volume manufacturing. This approach not only streamlines production, but also reduces costs without compromising quality while supporting sustainability goals by reducing manufacturing and transportation emissions.

Pouch Cell Thermal Runaway Barrier

Encapsulated ATP Pads are a ground-breaking anti-thermal propagation technology for pouch cells. Using a combination of lightweight material technology and specialist encapsulation films these solutions prevent thermal propagation from a thermal runaway event.

multiple benefits of advanced thermal cell barriers

Multiple functions

  • Critical in preventing heat from a cell in a thermal runaway event propagating to neighbouring cells.
  • Integrated spacer provides optimal spacing, allowing the insulation pad to provide consistent thermal insulation and effective cell wall pressure over a significantly higher number of cycles.
  • Adhesive layers on either side increase the stiffness of the pad and enhance the overall vibration and shock performance.

Streamlines Supply Chain

  • The compact production line can be integrated into existing clean manufacturing facilities.
  • Can be situated in close proximity to battery assembly plants.
  • Highly efficient manufacturing process eliminates the requirement for component parts to be pre-produced as a sub-assembly.

Fully customisable

  • ATP pads can be produced in various sizes with or without frames and in multiple material options.
  • Suitable for prismatic cells, pouch cells, cylindrical cells and solid state cells.
  • Can be used in both EV battery packs and battery storage systems.
