Abstract
Robust separator, which has on a substrate and in the intermediate spaces of the substrate, which comprises fibres of an electrically nonconducting material, an electrically nonconductive coating of oxide particles which are adhesively bonded to one another and to the substrate by an inorganic adhesive and comprise at least one oxide, selected from AlO, ZrOand SiO, wherein polymer particles are also present in the ceramic coating in addition to the oxide particles of AlO, ZrOand/or SiO. These separators are particularly easy to handle, since they are mechanically very stable.
