A mixture Ia, comprising a mix Iia, is composed of (a) from 1 to 95% by weight of a lithium-ion-conducting solid III, preferably a basic solid III, with a primary particle size of from 5 nm to 20 < mu>m and (b) from 5 to 99% by weight of a polymeric composition IV, btainable by polymerizing (b1) from 5 to 100% by weight, based on the composition IV, of a condensation product V of <alpha> at least one compound VI which is capable of reacting with a carboxylic acid or with a sulfonic acid or with a derivative or a mixture of two or more of these, and <beta> at least 1 mol per mole of the compound VI of a carboxylic acid or sulfonic acid VII which has at least one functional group capable of free-radical polymerization, or of a derivative thereof or of a mixture of two or more thereof and (b2) from 0 to 95% by weight, based on the composition IV, of another compound VIII with an average molecular weight (number average) of at least 5000 having polyether segments in its main or side chain, where the proportion of the mix Iia in the mixture Ia is from 1 to 100% by weight. |
