Abstract
(DE)
Gegenstand der Erfindung ist ein Separator, der auf einem Substrat und in den Zwischenräumen des Substrats, welches Fasern aus einem elektrisch nicht leitendem Material aufweist, eine poröse, nicht elektrisch leitfähige Beschichtung aus durch einen anorganischen Kleber miteinander und mit demSubstrat verklebten Oxidpartikeln, die zumindest ein Oxid, ausgewählt aus Al2O3, SiO2 aufweisen, aufweist, dadurch gekennzeichnet, dass in der keramischen Beschichtung zumindest ein Zucker vorhanden ist.
(EN)
The invention relates to a separator, which comprises on a substrate and in the intermediate spaces of the substrate, which substrate comprises fibres made of an electrically non-conductive material, a porous, electrically non-conductive coating made of oxide particles which include at least one oxide selected from Al2O3, SiO2 and are adhered by an inorganic glue to one another and to the substrate, characterised in that at least one sugar is present in the ceramic coating.
(FR)
L'invention concerne un séparateur qui, sur un substrat et dans les espaces intermédiaires du substrat qui possèdent des fibres d'un matériau non électroconducteur, comprend un revêtement poreux non électroconducteur fait de particules d'oxyde collées ensemble et sur le substrat à l'aide d'une colle anorganique, qui comprennent au moins un oxyde choisi parmi Al2O3, SiO2, caractérisé en ce qu'au moins un sucre est présent dans le revêtement céramique.
