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 invention relates to an electrolyte separator system comprising an ionic liquid, a conductive salt and a ceramic separator, and the use of the electrolyte separator system according to the invention in electrochemical energy storage systems, in particular of lithium metal and lithium ion batteries.

Film former-free electrolyte/separator system and use thereof in electrochemical energy accumulators

The invention relates to an electrolyte composition consisting of an ionic liquid, a conducting salt, a film former and a viscosity modifier and also to the use of the electrolyte composition of the present invention as an electrolyte material for electrochemical energy storage systems, especially for lithium-metal and lithium-ion batteries.

The invention relates to a method for catalytically oxidizing unsaturated hydrocarbons to form oxidation products, and to the production of saturated alcohols, ketones, aldehydes or carboxylic acids by subsequently hydrogenating the oxidation product. A compound of formula (I) is used as a catalyst during oxidizing in which: R1, R2=H, an aliphatic or aromatic alkoxy radical, carboxyl radical, alkoxycarbonyl radical or hydrocarbon radical, each having 1 to 20 carbon atoms, SO3H, NH2, OH, F, Cl, Br, I and/or NO2, whereby R1 and R2 signify identical or different radicals or R1 and R2 can be coupled to one another via a covalent bond, with Q1, Q2=the same or different, C, CH, N; X, Z=C, S or CH2; Y=O or OH; k=0, 1 or 2; 1=0, 1 or 2; m=1 to 100 in the presence of a radical initiator. Peroxy compounds or azo compounds can be used as radical initiators. Preferred substrates are cyclic aliphatic or aromatic compounds.

Method for producing saturated alcohols, ketones, aldehydes and carboxylic acids

The invention relates to a method for oxidizing substrates such as hydrocarbons, waxes or soot. The method involves the use of a compound of formula (I) in which: R1 and R2 represent H, an aliphatic or aromatic alkoxy radical, carboxyl radical, alkoxycarbonyl radical or hydrocarbon radical, each having 1 to 20 hydrocarbon atoms, SO3H, NH2, OH, F, Cl, Br, I and/or NO2, whereby R1 and R2 designate identical or different radicals or R1 and R2 can be linked to one another via a covalent bonding; Q1 and Q2 represent C, CH, N, CR5, each being the same or different; X and Z represent C, S, CH2, each being the same or different; Y represents O and OH; k=0, 1, 2; l=0, 1, 2; m=1 to 3, and; R5 represents one of the meanings of R1. Said compound is used as a catalyst in the presence of a radical initiator, whereby the molar ratio of the catalyst to the hydrocarbon is less than 10 mol %. Peroxy compounds or azo compounds can be used as the radical initiator. Preferred substrates are aliphatic or aromatic hydrocarbons.
