The present invention relates to a method for the production of low-chloride lithium hexafluorophosphate starting from lithium fluoride and phosphorus pentafluoride and its use in an electrolyte.

The present invention relates to pure lithium hexafluorophosphate and its use in an electrolyte as well as a method for reducing the fluoride content in lithium hexafluorophosphate.

Lithium hexafluorophosphate (LiPF 6) solution obtained by treating a non-aqueous halide containing LiPF 6 solution with at least one sodium hydride or sodium metal as an additive, is claimed, where the LiPF 6 is dissolved. Independent claims are included f...

Disclosed is a method for producing a lithium ion battery electrolyte solution containing lithium hexafluorophosphate as an electrolyte and a lithium ion battery using the electrolyte solution. The electrolyte solution is produced by reacting lithium chlor...
