A lithium sulfur battery with a low solvating electrolyte at an amount of less than 2 μl per mg sulfur. The electrolyte comprises dioxolane and hexylmethylether, as well as a Li salt, for example LiTSFi. The electrolyte is free from lithium nitrate, LiNO.

LiS battery with low solvating electrolyte

The invention relates to a coating which has special absorption properties for electromagnetic radiation from the wavelength spectrum of sunlight and to a method for producing the coating and to its use. The coating is formed by a layer which is formed on the surface of a substrate or on a reflective layer formed on the surface of the substrate. Carbon nanotubes are contained in the layer. The proportion of carbon nanotubes contained per unit of area or unit of volume and/or the layer thickness of the layer is selected such that it absorbs electromagnetic radiation from the wavelength spectrum of sunlight at predefinable proportions and the proportion of electromagnetic radiation from the wavelength spectrum of a black radiator at a temperature greater than 50&#xb0; C. which is emitted is very small.

Coating, method for the production thereof and use thereof

A method for manufacturing photocatalytically active titanium dioxide layers on substrate surfaces. The method reduces the effort for the manufacture of photocatalytically active titanium dioxide layers and increases the choice for the coating of suitable substrate materials. In the method, a titanium compound present in the gas phase and water vapor are directed to a preheated substrate by means of gas phase hydrolysis and a titanium dioxide layer is foamed on the surface of the substrate by chemical reaction. In this respect, the titanium compound and water vapor are supplied separately from one another so that a flow speed of at least 0.5 m/s is achieved and the time between the first contact of the two gases up to the impact on the surface of the substrate is kept lower than 0.05 s, and in this process the photocatalytically active titanium dioxide layer is formed on the substrate surface.
