Magnesium Ethylenediamine Borohydride as Solid-State Electrolyte for Magnesium Batteries
Solid-state magnesium ion conductors with exceptionally high ionic conductivity at low temperatures, 5 × 10(−8) Scm(−1) at 30 °C and 6 × 10(−5) Scm(−1) at 70 °C, are prepared by mechanochemical reaction of magnesium borohydride and ethylenediamine. The coordination complexes are crystalline, support...

description | Solid-state magnesium ion conductors with exceptionally high ionic conductivity at low temperatures, 5 × 10(−8) Scm(−1) at 30 °C and 6 × 10(−5) Scm(−1) at 70 °C, are prepared by mechanochemical reaction of magnesium borohydride and ethylenediamine. The coordination complexes are crystalline, support cycling in a potential window of 1.2 V, and allow magnesium plating/stripping. While the electrochemical stability, limited by the ethylenediamine ligand, must be improved to reach competitive energy densities, our results demonstrate that partially chelated Mg(2+) complexes represent a promising platform for the development of an all-solid-state magnesium battery. |
