LithiumSafe Separator, ultra-thin fire insulation for Lithium battery systems

The LithiumSafe Separator is an ultra-thin fire-resistant insulation material that has been specifically developed to block and prevent the spread of a lithium fire inside of a battery system. The material is only a few millimeters thick and can withstand a lithium fire for a period of approximately 20 minutes. At the same time, it keeps the reversed ‘cold’ side below a temperature of 120 °C for a minimum of 10 minutes. It is designed to be installed in between cells, modules and packs and on the chassis.

The lightweight and minimal thickness of the LithiumSafe Separator is benefitial for EV manufacturers since, generally spoken, adding protective materials means less space for battery cells. The LithiumSafe Separator provides excellent fire protection whilst saving a considerable amount of space. This ultimately leads to an increase of the vehicle’s range.

The LithiumSafe Separator is manufactured in both flexible and rigid form, any size and shape, enabling application for all battery types, cylindrical, prism and pouch. Furthermore, the material can be provided with self adhesive backing strips for easy and effective fixation.
