## Description

- description: To identify the key factors for achieving high-voltage MRBs, this study
    investigates ether-based weakly coordinating anion (WCA) electrolytes— Mg[B(OCH(CF3)2)4]2
    (BHFIP) and Mg[Al(OCH(CF3)2)4]2 (AlHFIP)—under varying water content to elucidate
    their electrochemical behavior on carbon-coated Al current collectors and MnO2
    cathodes. The two electrolytes are found to exhibit different characteristics
    in moisture, but as a common conclusion, trace water can promote electrolyte decomposition
    and CEI formation. Ultimately, the BHFIP electrolyte designed with a low water
    content successfully enables reversible Mg||MnO2 cells cycling under high voltage
    (4 V cut-off, > 50 cycles) by mitigating side reactions, whereas higher water
    content accelerates solvent/anion decomposition and MnO2 dissolution. The work
    highlights trace water content as a critical factor in ether-based MRB’s electrolyte
    design, demonstrating that optimized BHFIP electrolytes have potential in stabilizing
    high-voltage MRBs while emphasizing the need for moisture-resistant functional
    materials to enhance battery performance.
