Highly soluble alkoxide magnesium salts for rechargeable magnesium batteries†
Abstract
A unique class of air-stable and non-pyrophoric magnesium electrolytes has been developed based on alkoxide magnesium compounds. The crystals obtained from this class of electrolytes exhibit a unique structure of tri-magnesium cluster, [Mg3Cl3(OR)2(THF)6]+ [(THF)MgCl3]−. High reversible capacities and good rate capabilities have been obtained in Mg–Mo6S8 batteries using these new electrolytes at both 20 and 50 °C.
