| abstract |
The invention relates to a LiPF6 production process, wherein LiF is reacted with PCl5 or PCl3 at a temperature of -20 to 300 °C for a reaction time of 0.1 to 10 hours to give LiPF6, and LiPF6 is isolated as a solution from the reaction mixture, using ether, nitrile, sulphone, carbonate, halogenated hydrocarbon and/or tertiary amines as the solubilizing agent. |
