Abstract: A composite comprises at least one 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) which includes: (IIa) from 1 to 100% by weight of a polymer or copolymer (IIa) which has, along the chain, terminally and/or laterally, reactive groups (RG) which are capable of crosslinking reactions when exposed to heat and/or UV radiation, and (IIb) from 0 to 99% by weight of at least one polymer or copolymer (IIb) which is free from reactive groups RG, where the at least one layer has been applied to at least one second layer comprising at least one conventional separator.

Abstract: The present invention relates to composite bodies that include at least one layer having the following composition: (a) between 1 and 99 wt % of a solid (I) having a primary particle size of 5 nm to 100 .mu.m or a mixture of at least two solids; (b) between 99 and 1 wt % of a polymer binder (II). This polymer binder comprises: between 1 and 100 wt % of a polymer (IIa) or a copolymer (IIa) having reactive groups (RG) located on the chain, at the end s and/or on the sides and capable of cross-linking reactions thermally and/or under the action of UV; and between 0 and 99 % of at least one polymer or copolymer (IIb) free from reactive groups. The at least one layer is applied on at least a second layer comprising at least one traditional separator.
