General description
Ammonium hexafluorophosphate decomposes on heating before melting. Solubility of ammonium hexafluorophosphate in H2O at 20oC is 74.8% w/v. Additionally, it is very soluble in Me2CO, MeOH, EtOH and MeOAc, and is decomposed by boiling mineral acids.
Application
Ammonium hexafluorophosphate is used to synthesize polyethylene oxide based highly conductive non aqueous polymer gel electrolytes exhibiting high conductivity (>10-2S/cm at 25oC)

Is it possible to exceed the lithium redox potential in electrochemical systems? It seems impossible to exceed the lithium potential because the redox potential of the elemental lithium is the lowest among all the elements, which contributes to the high
