A High-Performance Magnesium Triflate-based Electrolyte for Rechargeable Magnesium Batteries
Original language description
The quest for a suitable electrolyte formulation is pivotal to the suc-cess of rechargeable magnesium batteries. A simple conventionalelectrolyte having high compatibility with magnesium anode andcathodematerialisingreatdemand. Herein, we report a simpleyet effective electrolyte formulation, comprising magnesium triflate(Mg(OTf)2) and magnesium chloride in monoglyme, that can enablehighly reversible, conditioning-free, and homogeneous magnesiumdeposition. Galvanostatic Mg plating/stripping demonstrates anaverage Coulombic efficiency of99.4% over 1,000 cycles. The cellsshow excellent performance at current densities up to 3 mA cm2and areal capacities up to 5 mAh cm2.Postmortemanalysis unveilsthe formation of a robust solid electrolyte interphase, which leads toimproved kinetics at the magnesium electrode. A prototype Mgbattery with Mo6S8cathode demonstrates stable cycling perfor-mance over 100 cycles. This study shows that rational design ofMg(OTf)2-based electrolytes is a promising direction toward therealization of high-performance magnesium batteries.
