Abstract
A method of making a salt of the formula: Mg[Al(R)4]2, where R represents a compound selected from a deprotonated alcohol or thiol; an amine; or a mixture thereof. The method comprising the steps of; combining a Mg(AlH4)2 precursor with an alcohol, thiol or amine of the general formula R—H to create a reaction liquor containing Mg[Al(R)4]2; and washing the reaction liquor in an organic solvent.
Claims5
A method of making an electrolyte, the method comprising:
- forming a Mg[AlH4]2 precursor by a one-step ball milling process of NaAlH4 and MgCl;
- combining the Mg[AlH4]2 precursor with a deprotonated alcohol, thiol, amine, or a mixture thereof to create a reaction liquor containing Mg[Al(R)4]2, wherein R represents the deprotonated alcohol, thiol, amine, or the mixture thereof;
- washing the reaction liquor in an organic solvent selected from the group consisting of dry DME, 2-methyl-THF, diglyme, triglyme, and tetraglyme to obtain a salt;
- and
- combining the salt with an Mg(PF6)2 additive.
