2,5-Dimethoxy-1,4-Benzoquinone (DMBQ) as Organic Cathode for Rechargeable Magnesium-Ion Batteries
2,5-Dimethoxy-1,4-benzoquinone (DMBQ) was reinvestigated as a cathode material with magnesium electrolytes that are capable of plating/stripping magnesium for rechargeable magnesium-ion batteries. Two electrolytes, the magnesium bis(trifluoromethylsulfonyl)imide mixed with MgCl2 in dimethoxyethane (Mg(TFSI)(2)-2MgCl(2) in DME) electrolyte, and the Mg(TFSI)(2) in diglyme were selected. The Mg(TFSI)(2)-2MgCl(2) in DME enabled Mg-DMBQ batteries with a discharge potentials above 2.0 V vs Mg/Mg2+, which is superior to the previous reported potential in Mg-DMBQ batteries with conventional magnesium salt-based electrolytes (1.1 V, vs Mg/Mg2+), and also excels the well-known Chevrel phase Mo6S8 in magnesium-ion batteries (1.2 V, vs Mg/Mg2+).
