To realize an energy storage transition beyond Li-ion competitive technologies, earth-abundant elements, such as Mg, are needed. Carborane anions particularly well-suited to realizing magnesium-ion batteries (MIBs), their inert and weakly coordinating properties beget excellent electrolyte performance. However, utilizing these materials in actual electrochemical cells has been hampered by the reliance on Mg2+ salts of commercially available [HCB11H11]− anion, which is not soluble more binding solvents apart from higher glymes. Herein, we demonstrate it possible iteratively engineer anion surface synthetically address previous solubility issues yield a highly conductive (up 7.33 mS cm–1) electrochemically stable +4.2 V vs Mg2+/0) magnesium that surpasses state art. This novel non-nucleophilic exhibits dissociative behavior regardless concentration tolerant prolonged periods cycling symmetric at high current densities 2.0 mA cm–2, 400 h).
