The invention relates to a separator filled with an electrolyte composition. The separator has a ceramic surface and the electrolyte composition comprises an ionic fluid. Filling with the electrolyte composition can take place, for example, by inserting the separator into a battery, e.g. into a lithium ion battery, which is filled with a corresponding electrolyte composition.

Use of a ceramic separator in lithium ion batteries, comprising an electrolyte containing ionic fluids

The present invention relates to a vapor-pervious water-impervious substrate, preferably a fibrous nonwoven web, which can be used in particular as a textile continuous sheet material, for example as an awning or as an inlet in apparel. The substrate according to the present invention may have self-cleaning properties. The substrate according to the present invention is simple to produce in an at least two-step process wherein a coating on the fibers of the substrate is produced in the first step and then hydrophobic particles are applied to the coated fibers by means of an adhesion promoter.

Textile substrates having self-cleaning properties

Separator-electrode assemblies (SEAs) comprising a porous electrode useful as a positive or negative electrode in a lithium battery and a separator layer applied to this electrode, the separator layer being an inorganic separator layer comprising at least two fractions of metal oxide particles different from each other in their average particle size and/or in the metal, and the electrode having active mass particles that are bonded together and to a current collector by an inorganic adhesive; and a process for their production.

Inorganic separator-electrode-unit for lithium-ion batteries, method for the production thereof and use thereof in lithium batteries

A pyrogenic oxidic powder composed of particles, comprising (i) atoms of an element of groups 3A, 4A, 3B or 4B of the periodic table of the elements, and (ii) oxygen atoms, said particles being characterized by lithium atoms attached to said atoms via an oxygen bridge.
