A lithium-air battery cell with an electrolyte composition comprising LiPO 2 F 2 is described. The electrolyte composition comprises an electrolyte solvent, for example, one or more non-fluorinated solvents, e.g. ethylene carbonate, a dialkyl carbonate or propylene carbonate, and/or one or more fluorinated organic solvents, e.g. fluoroethylene carbonate, cis-difluoroethylene carbonate, trans-difluoroethylene carbonate, 4,4-difluoroethylene carbonate, trifluoroethylene carbonate, tetrafluoroethylene carbonate, 4-fluoro-4-methyl-1,3-dioxolane-2-one, 4-fluoro-4-ethyl-1,3-dioxolane-2-one, 2,2,2-trifluoroethyl-methyl carbonate, 2,2,2-trifluoroethyl-fluoromethyl carbonate are preferred. The solvent may further comprise other additives. Also described is a vehicle battery, especially a car battery constituted of a multitude of lithium-air battery cells of the invention. The battery can be used to provide electrical energy to consumers for electric current including an electric motor driving the vehicle.
摘要:
Method for the manufacture of electronic devices with purified fluorine Elemental fluorine is used as etching agent for the manufacture of electronic devices, i.a., semiconductor devices, micro-electromechanical devices, thin film transistors, flat panel displays and solar panels, and as chamber cleaning agent mainly for PECVD apparatus. For this purpose, fluorine often is produced on- site. The invention provides a process for the manufacture of electronic devices wherein fluorine is produced on site and is purified from HF by a low temperature treatment. A pressure of between 1.5 and 20 Bara is especially advantageous.
