Electrolytic solution for rechargeable magnesium batteries, method for preparing the same, and rechargeable magnesium batteries

Abstract

The present application provides an electrolytic solution for rechargeable magnesium batteries, a method for preparing the same, and a rechargeable magnesium battery, wherein the electrolytic solution comprises an electrolyte salt and a non-aqueous solvent, the electrolyte salt comprising [MgxM2x-1Py][Mg(ORF)3Qz], in which x represents an integer between 1 and 6, y represents an integer between 1 and 6, z represents an integer between 0 and 6, M represents a monovalent anion, and each RF independently represents partially fluorinated or perfluorinated C1-C6 aliphatic hydrocarbon group, or partially fluorinated or perfluorinated C6-C12 aromatic hydrocarbon group, and P and Q represent an ligand. The electrolytic solution provided by the present application has excellent electrochemical properties, and at the same time the interfacial stability between the electrolytic solution and the negative electrode is also high.
