A composite comprises at least one first layer which includes a composite comprising(a) from 1 to 99% by weight of a solid (I) with a primary particle size of from 5 nm to 100 mum or a mixture made from at least two solids,(b) from 99 to 1% by weight of a polymeric binder (II) obtainable by polymerizingb1) from 5 to 100% by weight, based on the binder (II), of a condensation product III made fromat least one compound IV which is capable of reacting with a carboxylic acid or with a sulfonic acid or with a derivative or with a mixture of two or more of these, andat least one mol per mole of compound IV of a carboxylic or sulfonic acid V which has at least one functional group capable of free-radical polymerization, or of a derivative of these or of a mixture of two or more of theseandb2) from 0 to 95% by weight, based on the binder (II), of another compound VII with an average molecular weight (number average) of at least 5000 having polyether segments in a main or side chain,where the at least one layer has been applied to at least one second layer comprising at least one conventional separator.
