    Magnesium Batteries

## Description

- description: We revisited very different organic solvent-based electrolytes for
    RMB applications to clarify the possible molecular design toward anodically-stable
    ether-based electrolyte solutions. Through the comprehensive experimental and
    computational surveys, the intrinsic electrochemical/chemical stabilities against
    magnesium metal and the well-balanced solvating ability are found to be necessary
    to achieve the solvents with desired functionalities. Based on this knowledge,
    the glyme-analogues bearing trifluoroalkyl groups were designed and synthesized.
    By combining suitable fluorinated glyme-based solvents with appropriate supporting
    salts, the anodically-stable electrolytes those support electrochemical magnesium
    deposition/dissolution have been developed. These electrolytes showed the remarkable
    anodic limit of 4.4 V vs. Mg2+/Mg, highest ever reported to the best of our knowledges,
    and effectively suppressed undesired corrosion of Al current collectors. The application
    of such electrolytes to RMBs with high-voltage oxide-based cathodes however failed.
    The modest compatibility against magnesium metal anodes caused positive shift
    of the electrode potential of the magnesium metal anodes. Moreover, fragility
    against oxide-based cathodes caused undesired catalytic decomposition of the fluorinated
    solvents during charging. Based on the above findings and knowledges on RMBs,
    the basic concepts in designing feasible electrolyte materials and possible options
    toward constructing high-voltage magnesium batteries are proposed.
