Synthesis of Electroactive Ionic Liquids for Flow Battery Applications

摘要

The present disclosure is directed to synthesizing metal ionic liquids with transition metal coordination cations, where such metal ionic liquids can be used in a flow battery. A cation of a metal ionic liquid includes a transition metal and a ligand coordinated to the transition metal.

主权项

1. A metal ionic liquid comprising:
a cation comprising a transition metal selected from the group consisting of Fe, Cu, Mn, Zn and combinations thereof and a ligand coordinated to the transition metal, wherein the ligand comprises an amine functional group and a hydroxyl functional group; and an anion selected from the group consisting of 2-ethylhexanoate, hexafluorophosphate, triflate, triflimide, tetrafluoroborate and combinations thereof, the metal ionic liquid being a non-aqueous liquid.
