An article comprising:
- a plurality of layers, the layers comprising:
- one or more nonwoven layers, wherein at least one nonwoven layer comprises polyacrylonitrile fibers, oxidized polyacrylonitrile fibers, inorganic fibers, or a combination thereof;
- one or more E-glass layers;
- one or more E-CR glass layers;
- wherein each of the one or more nonwoven layers has a temperature resistance of about 200° C. or greater;
- wherein at least one of the one or more nonwoven layers is coated with a ceramic coating;
- wherein the article is adapted to provide thermal insulation for a battery and avoid and/or confine fire propagation during a battery thermal runaway event;
- and
- wherein the article provides a time period of at least 5 minutes between a detection of the battery thermal runaway event and an actual impact of the battery thermal runaway event within a passenger compartment of a vehicle.
