Flexible multilayer material resistant to the explosion of an electric battery

A multilayer material comprising n base units with n being a natural, non-zero integer, each of the base units comprising a laminate comprising, in order:

• a cross-linked silicone resin layer comprising resin including graphite particles expandable from a temperature greater than a cross-linking temperature of said resin;
• an impregnated silica or alumina fabric or knit layer, the fabric or knit being provided with gaps, all the gaps being impregnated with said cross-linked silicone resin or another cross-linked silicone resin comprising graphite particles expandable from a temperature greater than a cross-linking temperature of said resin;
• wherein:
• the number n of base units is between 1 and 5 inclusive,
• the nth base unit being covered with another cross-linked silicone resin layer, further comprising graphite particles expandable from a temperature greater than a cross-linking temperature of said resin, to form the laminate formed of an alternating resin layer and a fabric or knit layer.
