1. A multilayer material for use as a thermal insulation barrier in a rechargeable electrical energy storage system, the multilayer material comprising:
at least one inorganic fabric layer;
a nonwoven layer comprising inorganic particles and inorganic fibers; and
an inorganic adhesive layer, located between the at least one inorganic fabric layer and the nonwoven layer, the inorganic adhesive layer comprising:
inorganic constituents present in an amount of at least 99 wt. %, and
