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 3,4-dicyano-2-trifluoromethylimidazole (TDI). The methods comprise contacting TDI with an alkaline earth metal bis(trifluoroacetate) salt in trifluoroacetic acid.
