While a range of barrier materials are on the market, none completely address the full complexity of a thermal runaway event.
A successful mitigation strategy must address all the relevant threats to battery pack components.
Exposure to flame
Excessive heat transfer
Forceful ejection of particulates from compromised cells
FLAME & THERMAL TRANSFER BARRIER PROPERTIES
It is necessary that a barrier material restrict thermal transfer between battery components to prevent propagation during a thermal runaway event.
Common barrier materials may withstand exposure to open flame but fail to prevent thermal transfer for any meaningful duration.
XTS POUCH
FR SILICONE
MICA
CERAMIC FIBER FABRIC
XTS Pouches, either alone or in conjunction with a barrier material, are necessary to meaningfully restrict the thermal transfer associated with a runaway event, out-competing common barrier materials.
Ejecta Barrier properties
During thermal runaway, a compromised cell will release gas and particulate ejecta at high velocity. A barrier material must be able to withstand this ejecta, which is challenging for most common barrier materials.

The xts solution
The selection of barrier materials to protect your battery pack from thermal runaway propagation is a vital design consideration. XTS products’ unique ability to capture and remove heat from the system is a necessary component of any complete barrier solution. LHS can provide tailored solutions utilizing XTS alone or in combination with other materials to meet the most rigorous safety requirements.
