Back Cover: A Stable, Non-Corrosive Perfluorinated Pinacolatoborate Mg Electrolyte for Rechargeable Mg Batteries (Angew. Chem. Int. Ed. 21/2019)
Graphical Abstract
A chloride-free electrolyte termed magnesium fluorinated pinacolatoborate, Mg[B(O2C2(CF3)4)2]2, is reported by T. L. Liu and co-workers in their Communication on page 6967 ff. This electrolyte demonstrates reversible Mg deposition with a low overpotential of 197 mV and an anodic stability of 4.0 V versus Mg. This enabled the production of a high-voltage, rechargeable Mg/MnO2 battery with a discharge capacity of 150 mAh/g.
