Abstract: Disclosed is a calcium salt, Ca(HMDS)2, where HMDS is the hexamethyldisilazide anion (also known as bis(trimethylsilyl)amide), enables high current densities and high coulombic efficiency for calcium metal deposition and dissolution. These properties facilitate the use of this salt in batteries based on calcium metal. In addition, the salt is significant for batteries based on metal anodes, which have higher specific energies than batteries based on intercalation anodes, such as LiC6. In particular, a calcium based rechargeable battery includes Ca(HMDS)2 salt and at least one solvent, the solvent suitable for calcium battery cycling. The at least one solvent can be diethyl ether, diisopropylether, methyl t-butyl ether (MTBE), 1,3-dioxane, 1,4-dioxane, tetrahydrofuran (THF), tetrahydropyran, glyme, diglyme, triglyme or tetraglyme, or any mixture thereof.

Abstract: 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—, AlXaRb— (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.
