- Abstract
- New electrolytes are necessary for the development of eco-friendly and cost-effective solid-state magnesium batteries. Methylamine borane-magnesium borohydride Mg(BH4)2-CH3NH2BH3 combined with MgO is suggested as a novel solid state electrolyte. In fact, Mg(BH4)2-CH3NH2BH3 0.33–0.67 (molar fraction) is a viscous liquid at room temperature, but it can be stabilized in the solid state after the incorporation of 75 wt% of MgO. The obtained composite exhibits remarkable Mg2+ conductivity, achieving approximately 10–5 S cm-1 at 25 °C and 10–4 S cm–1 at 65 °C.
