Title: Salts for multivalent ion batteries

Abstract

Methods for preparing electrolyte salts for alkaline earth metal-ion batteries (e.g., calcium and magnesium ion batteries) are described. The electrolyte salts comprise alkaline earth metal (e.g., Mg or Ca) salts of bis(fluorosulfonyl)imide (FSI) and 3,4-dicyano-2-trifluoromethylimidazole (TDI). The methods comprise contacting FSI or TDI with an alkaline earth metal bis(trifluoroacetate) salt in trifluoroacetic acid.
