Abstract: 
Magnesium batteries are promising candidates for post-lithium energy storage systems due to their low cost, high volumetric energy density, and low risk of dendrite formation. This study reports a new magnesium ion conducting ionogel electrolyte based on a Metal-Organic Framework (MOF) structure (UiO-66) impregnated with an ionic liquid, magnesium bis[(trifluoromethyl)sulfonyl]imide in 1-ethyl-3-meth- ylimidazolium bis[(trifluoromethyl)sulfonyl]imide. Comparably high conductivity of 5.7 x10(-5) Scm(-1) can be achieved at room temperature. By employing the prepared MOF-ionogel electrolyte, a reversible quasi-solid-state magnesium battery (QSSMB) is reported. Surface analysis unveils the possible origin of the large overpotential of magnesium plating and stripping. The findings suggest that MOF-based materials are a promising class of ionogel electrolyte templates for QSSMBs. The results on the magnesium anode will be useful to define optimization strategies for magnesium metal anodes in SSMBs.
