MANUFACTURE OF MIXTURES COMPRISING LIPO2F2 AND LIPF6

Mixtures comprising LiPO2F2 and LiPF6 both of which are electrolyte salts or additive for, i.a., Li ion batteries, are manufactured by the reaction of POF3 and LiF. The mixtures can be extracted with suitable solvents to provide solutions containing LiPO2F2 and LiPF6 which can be applied for the man...

Beschreibung
Zusammenfassung:Mixtures comprising LiPO2F2 and LiPF6 both of which are electrolyte salts or additive for, i.a., Li ion batteries, are manufactured by the reaction of POF3 and LiF. The mixtures can be extracted with suitable solvents to provide solutions containing LiPO2F2 and LiPF6 which can be applied for the manufacture of Li ion batteries, Li-air batteries and Li-sulfur batteries. Equimolar mixtures comprising LiPO2F2 and LiPF6 are also described, as well as a method for the manufacture of electrolyte compositions obtained by the extraction of equimolar mixtures comprising LiPO2F2 and LiPF6.
