Magnesium(II) Bis(trifluoromethane sulfonyl) Imide-Based Electrolytes with Wide Electrochemical Windows for Rechargeable Magnesium Batteries
We present a promising electrolyte
candidate, MgÂ(TFSI)<sub>2</sub> dissolved in glyme/diglyme, for future
design of advanced magnesium (Mg) batteries. This electrolyte shows
high anodic stability on an aluminum current collector and allows
Mg stripping at the Mg electrode and Mg deposition on the stainless
steel or the copper electrode. It is clearly shown that nondendritic
and agglomerated Mg secondary particles composed of ca. 50 nm primary
particles alleviating safety concern are formed in glyme/diglyme with
0.3 M MgÂ(TFSI)<sub>2</sub> at a high rate of 1C. Moreover, a MgÂ(TFSI)<sub>2</sub>-based electrolyte presents the compatibility toward a Chevrel
phase Mo<sub>6</sub>S<sub>8</sub>, a radical polymer charged up to
a high voltage of 3.4 V versus Mg/Mg<sup>2+</sup> and a carbon–sulfur
composite as cathodes
