Abstract: The invention relates to a separator which has a porous coating which is not electrically conductive and is composed of oxide particles which are adhesively bonded to one another and to the substrate by means of an inorganic adhesive and comprise at least one oxide selected from among Al2O3 and SiO2 on a substrate and in the interstices of the substrate which has fibres composed of a material which is not electrically conductive, characterized in that at least one sugar is present in the ceramic coating.

Abstract: The invention relates to a battery (0), comprising a plurality of self-contained, substantially cuboid cell housings (1), in each of which a side face is formed at least in some regions as a negative pole (?) and the opposite side face is designed at least in some regions as a positive pole (+), wherein the cell housings (1) bear against one another, with the pole (?) on the pole (+), and extend between a positive contact (14) and a negative contact (13), and wherein the cell housings (1) are each enclosed by an electrically non-conductive, mechanically supporting frame (2). The aim of the invention is to provide such a battery which has lower internal resistance and is therefore suitable for applications which require rapid charging or discharging (high-power applications).
