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

摘要

There is provided a method for producing an electrolyte solution for lithium ion battery, which is characterized in that lithium fluoride, lithium chloride, lithium bromide, lithium iodide or a mixture of any of these is reacted with phosphorus pentachloride and hydrogen fluoride in a nonaqueous organic solvent, when an electrolyte solution for lithium ion battery, which contains lithium hexafluorophosphate as an electrolyte, is produced.
