LiPO2F2 is manufactured by the reaction of P4O10 with LiF forming a reaction mixture comprising LiPO2F2. To isolate pure LiPO2F2, the reaction mixture is extracted with water, organic solvents or mixtures thereof, and if desired, pure LiPO2F2 is isolated from the solution. The pure LiPO2F2 can be re-dissolved in suitable organic solvents, e.g. in fluorinated and/or non-fluorinated organic carbonates. Another aspect of the present invention is crystalline LiPO2F2. LiPO2F2 is suitable as electrolyte salt or as electrolyte salt additive for Li ion batteries, for lithium-sulfur batteries and for lithium-oxygen batteries. |
