Abstract: A lithium sulfur battery with a low solvating electrolyte at an amount of less than 2 ?l 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, LiNO3.

Abstract: The invention relates to an electrolyte, which is provided for an alkali-sulfur battery (e.g. for a Li—S battery). The electrolyte contains a non-polar, acyclic and non-fluorinated ether, a polar aprotic organic solvent, and a conducting salt for an alkali-sulfur battery. It has been found that, when such an electrolyte is used in an alkali-sulfur battery, a high-capacity, a low overvoltage, a high cycle stability, and a high Coulomb efficiency can be achieved in the alkali-sulfur battery and, in addition, as compared with an alkali-sulfur battery which contains a fluorinated ether in the electrolyte, a considerably improved gravimetric energy density is obtained. The invention further relates to a battery comprising the electrolyte according to the invention and to uses of the electrolyte according to the invention.

Abstract: The invention relates to alkaline secondary batteries. The secondary battery contains a cathode, an anode and an electrolyte, said secondary battery being arranged between the cathode and anode and comprises an alkali metal ion conductive contact to the cathode and to the carbon layer of the anode. The anode contains or consists of a carbon layer, whereby the carbon layer, alone or in combination with an electrically conductive substrate, forms with an electrically conductive contact.

Abstract: The invention relates to a process for producing metal-coated inorganic particles by means of currentless deposition technique in which the inorganic particles are first functionalized, then introduced into an aqueous metal-salt solution containing metal ions, and the metal is reduced by adding a reducing agent to the aqueous metal-salt mixture containing the functionalized particles and the metal is deposited on the functionalized particles, wherein the functionalization of the inorganic particles takes place by means of aminophosphonic acids, aminocarboxylic acids and/or aminoalcohol phosphoric acid esters, and the aminophosphonic acid, the aminocarboxylic acid and/or the aminoalcohol phosphoric acid ester form(s) a monolayer on the surface of the inorganic particles. The metal-coated inorganic particles can be introduced into metal matrices due to their improved surface properties.
