Abstract

Currently, only two types of hybrid Mg-Na electrolytes are known. Herein, we report a new hybrid Mg-Na electrolyte, based on Mg(TFSI)2 and NaBF4 salts in diglyme solvent, which engenders non-dendritic cycling of Mg metal when used in hybrid Mg-Na cells. Using NaTi2(PO4)3 as sodium intercalation-type cathode, NaTi2(PO4)3/C vs Mg cell delivered discharge capacity approaching 120 mAh/g with flat plateau at 1.25 V vs Mg/Mg2+, along with relatively good rate performance and cycling stability.
