Abstract

This study evaluated the influence of halide anion of phenoxyimine–magnesium halide complex on magnesium deposition–dissolution in Mg(TFSA)₂/triglyme electrolyte containing the magnesium halide complex. The chloride complex provides rather high Coulombic efficiency of reversible magnesium deposition compared with bromide analogue. This difference appears to be in relation to the different complexation equilibrium by Mg²⁺, Cl⁻, and solvent molecules.
