Chelating ionic liquids for magnesium battery electrolytes and systems

摘要

Ionic liquids suitable for use in magnesium batteries are disclosed. In an exemplary embodiment, a rechargeable magnesium battery comprises an anode electrode, a cathode electrode, and a chelating ionic liquid solution in contact therewith. The chelating ionic liquid may comprise at least one cation, at least one anion, and at least one soluble, magnesium salt. The magnesium salt may comprise MgX₂, wherein X comprises at least one of Cl—, Br—, I—, TFSI—, FSI—, ClO₄—, BF₄—, PF₆—, RSO₃— (wherein R consists of at least one of an alkyl or aryl group), RCO₂— (wherein R consists of at least one of an alkyl or aryl group), alkyl borides, alkyl borates, AlCl₄—, AlX_aR_b— (wherein the sum of subscripts a and b is 4, X consists of a halide, and R consists of at least one of an alkyl or aryl group), carboranes, or hexamethyldisilazide.
