Abstract
An object is to provide a method of manufacturing a hexafluorophosphate, that can simply and easily manufacture an inexpensive and high-quality hexafluorophosphate while suppressing the manufacturing cost, an electrolytic solution containing a hexafluorophosphate, and an electricity storage device including the electrolytic solution. The present invention relates to a method of manufacturing a hexafluorophosphate, which comprises reacting at least a phosphorus compound with a fluoride represented by MFs.r(HF) (wherein 0≦r≦6, 1≦s≦3, and M is at least one kind selected from the group consisting of Li, Na, K, Rb, Cs, NH4, Ag, Mg, Ca, Ba, Zn, Cu, Pb, Al and Fe) to produce a hexafluorophosphate represented by the chemical formula M(PF6)s.
