Abstract: A waste-gas line has a first pipe section connectable to a battery and having an inlet end and a first flange, a separate second pipe section having a second outlet end and a second flange, and an inner sleeve and an outer sleeve, both of a non-conductive material. The inner sleeve is positioned on an outer side of the first flange and of the second flange. The outer sleeve surrounds the first flange, the second flange and the inner sleeve. The first and the second flanges are fastened to one another in such a way that at least the second pipe section is electrically insulated by the inner and the outer sleeves and, by the combination of inner and outer sleeves, is heat-resistant up to a temperature of at least 1100° C. and pressure-resistant up to a pressure of at least 8 bar, for a duration of at least 120 seconds.
