| 摘要 |
Lithium hexafluorophosphate solution prepared by treating a non-aqueous, halide-containing dimethyl carbonate-lithium hexafluorophosphate solution with at least lithium hydride as additive, is claimed. Independent claims are also included for: (1) producing corrosion resistant lithium hexafluorophosphate solution, comprising neutralizing the dimethyl carbonate- lithium hexafluorophosphate solution by reacting with lithium hydride, and then separating the insoluble components; and (2) reducing the corrosiveness of the dimethyl carbonate solution, preferably dimethyl carbonate-lithium hexafluorophosphate solution to be used in electrochemical storage devices, comprising neutralizing the solution and separating the solids by filtering (preferred), sedimenting, centrifuging or floating, to remove the excess additive and/or other substances present in solid, preferably lithium fluoride and lithium hydride. |
