METHOD FOR PRODUCING ELECTROLYTE SOLUTION FOR LITHIUM ION BATTERY AND BATTERY USING SAME

摘要

Disclosed is a method for producing an electrolyte solution which contains lithium hexafluorophosphate as the electrolyte. In this method, the electrolyte solution is directly produced in an organic solvent. Specifically disclosed is a method for producing an electrolyte solution for lithium ion batteries which solution contains lithium hexafluorophosphate as the electrolyte. In this method for producing an electrolyte solution for lithium ion batteries, lithium fluoride, lithium chloride, lithium bromide, lithium iodide or a mixture of some of them is reacted with phosphorus pentachloride and hydrogen fluoride in a nonaqueous organic solvent.
