电解质六氟磷酸锂的制备与检测

Abstract

Abstract: With anhydrous hydrogen fluoride as the solvent，lithium fluoride was dissolved therein to prepare a solution.Then， phosphorus pentafluoride gas was passed into the solution to synthesize lithium hexafluorophosphate.Next，the solution was concentrated and crystallized，and filtered，and dried to obtain the lithium hexafluorophosphate sample.The sample was detected by Raman spectroscopy and XRD qualitative detection，and maps were consistent with the standard ones.Free acid content was tested by using organic solvent potentiometric titration.Moisture content was checked by using Karl Fischer method. Impurity content and lithium content were measured by atomic absorption spectrometry.All of the quantitative analysis showed that the sample prepared met electrolyte quality requirements for lithium-ion battery.

Key words: lithium hexafluorophosphate, preparation, detection
