## Description

- description: Rechargeable magnesium batteries (RMBs) are promising large-scale stationary
    energy storage devices. A manufacturing system similar to that used for lithium-ion
    batteries should be adoptable to the fabrication of RMBs. However, the compatibility
    of RMB components with atmospheric components other than moisture has not been
    studied yet. In this study, we investigated the effects of atmospheric conditions
    on the electrochemical dissolution–deposition behavior of magnesium in non-aqueous
    electrolytes and revealed for the first time that even a miniscule amount of O2
    in the electrolyte solution is a fatal impurity for reversible magnesium electrochemistry.
    The carbonate-based interface on magnesium metal negative electrodes induced by
    a contact with O2-bearing electrolytes impedes interfacial electrochemical reactions,
    which can be overcome by surface functionalization by appropriate elements. A
    diethylzinc-derived interface leads to remarkably stable magnesium dissolution–deposition.
