AI Technical Summary
Existing lithium hexafluorophosphate preparation processes suffer from low reaction rates, high costs, poor safety, and unstable product quality. In particular, the organic solvent method may produce harmful byproducts, affecting product purity and safety.
Lithium hexafluorophosphate is prepared by reacting phosphorus pentafluoride and lithium fluoride in a fluorinated solvent. By selecting a fluorinated solvent with a specific structure and controlling the reaction conditions, the reaction between the solvent and phosphorus pentafluoride is avoided, thereby improving the purity and safety of the product.
This method enables efficient and safe preparation of lithium hexafluorophosphate, reduces production costs, increases product yield and purity, and reduces the generation of waste, making it suitable for industrial production.
