Abstract[English]
In its main aspect, the invention relates to a flame shield for an electric vehicle battery, in particular a lithium-ion battery, and to a method for manufacturing it. The flame shield according to the invention comprises at least one flame-resistant layer consisting of a porous fibrous non-woven impregnated with polyurethane, wherein the fibers comprised in the porous fibrous non-woven have a melting temperature of at least 1100ºC, the polyurethane does not comprise any flame retardant and the polyurethane impregnates the fibrous-non woven in such a way that the flame-resistant layer is impervious to air- flow. In a second aspect, the invention concerns a battery housing wherein the battery lid and/or the battery tray comprise such a flame shield.[French]
