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: A deicing and/or anti-icing liquid recovery system for recovering deicing and/or anti-icing liquids from airport apron/deicing platform surfaces, the system includes: a deicing-liquid recovery unit; a pump; and a collection tank, where the deicing/anti-icing liquid recovery unit includes a rotatable brush; a baffle; and a sorting tray fluidly connectable to said collection tank via pump, where the rotatable cylindrical brush is arranged to sweep a apron/deicing platform surface such that materials on the apron/deicing platform surface is forced over the baffle and into the sorting tray, wherein said filter is configured to separate liquids and solid phase materials from said swept-up material, and where liquids collected in the sorting tray can be pumped to the collection tank via said pump.

Abstract: The invention provides a method of sampling de-icing fluid from an airplane de-icer having a spraying nozzle for spraying the de-icing fluid onto a surface of an airplane, the de-icing fluid preferably being produced by the airplane de-icer by mixing a number of ingredients. The method comprises the steps of: i) obtaining a limited sample of the de-icing fluid by diverting at least a part of the de-icing fluid flowing towards the spraying nozzle for a period of time during the spraying of the de-icing fluid onto the surface of the airplane, and ii) collecting sample of the de-icing fluid in a sample container. A system for sampling de-icing fluid is also provided as well as an airplane de-icer comprising the system.

Abstract: The invention pertains to a de-icer for airplanes, which comprises a self-propelled vehicle (32) which is provided with a lifting device (34, 36) for lifting and positioning a spraying nozzle (38) in the vicinity of an outer surface of an airplane to be de-iced. The nozzle (38) is fluidly connected to a tank assembly (40) via at least one pipe, wherein the tank assembly (40) comprises separate tanks (42, 44, 46) for an anti-freeze liquid, such as propylene or ethylene glycol, additives and water. Each tank (42, 44, 46) of the tank assembly (40) is fluidly connected to a mixing system (48) via pipes (50, 52, 54), the mixing system (48) is configured for mixing the liquids from each of the tanks (42, 44, 46) before supplying the mixed liquid to the nozzle (38). The invention also pertains to methods of providing onboard mixing of de-icing and anti-icing liquids in a de-icing vehicle.
