## Description

- description: We conducted comprehensive comparative studies on the representative
    WCA-based electrolytes incorporating tetrakis(hexafluoro-iso-propoxyl)borate ([B(HFIP)4]−)
    anions as a model system to understand the effect of valency of paired cation
    species on transport properties and electrochemical characteristics. As revealed
    by X-ray crystallography, the monovalent lithium and sodium salts were obtained
    as adducts, where the anion participated in cation coordination along with a single
    solvent molecule, whereas divalent magnesium, calcium, and zinc salts formed fully
    isolated solvates with the divalent cations being coordinated by solvents alone.
    Such valency-dependent differences in the dissociation states would affect the
    solution properties, as the divalent electrolytes exhibited greater conductivities
    than their monovalent counterparts, even though the same number of charged species
    were present in the respective solutions. The electrochemical metal deposition/dissolution
    studies combined with morphological and subsequent elemental analysis on the deposits
    suggested the specific favorable combination of magnesium cations and [B(HFIP)4]−
    anion in ethereal solutions. The modest surface reactivity of the deposited macrocrystalline
    magnesium, moderate reductive nature of the magnesium metal, and well-balanced
    mutual interactions among the components may have jointly contributed to such
    outstanding performance.
