From smartphones to electric vehicles – lithium-ion batteries are ubiquitous. Less well known are the dangers posed by a fire in such energy storage systems. The resulting smoke gases, for example, are acutely hazardous to health, especially hydrofluoric acid. A protective textile developed by the Research Center for Fire Protection Technology at the Karlsruhe Institute of Technology (KIT) together with Planex GmbH in Ludwigshafen opens up new options for fire fighting .
This protective textile is pulled over a small inflamed device like a bag. The gas-permeable layers of the bag prevent the flame from escaping, and a core made of mineral earth binds the poisonous smoke. If necessary, the bag can also be unfolded as a blanket. In the XXL version, this completely covers e-vehicles whose batteries can no longer be erased.
