The development of,efficient, inexpensive, and safe rechargeable batteries for large-scale environmentally benign cells is one of the key requirements to accommodate and satisfy various technological applications. To date, the development of magnesium battery as a promising candidate for next-generation battery systems has been-hindered-hy the lack, of high performance arid,stable electrolyte. In this work, we have developed:an original, safe, and high-performance class of electrolytes based on a simple: mixture of commercially available compounds, that is; Mg(TFSI)(2), anthracene, MgCl2,, and diglyme solvent, We have proven that-anthracene induCes stabilization of.the reduced, form of magnesium involving reversible magnesium plating/stripping with very high current density. The electrolyte investigated exhibits an unprecedented electrochemical stability window of up to 3.1 V, whereas MgCl2 addition allows the improvement of the Mg/electrolyte interface properties, and enables a large cyclability of Mg/Mo6S Chevrel phase-cell, allowing one to reach high performances.
