Abstract

A novel Mg(BH₄)₂·1.9NH₃-MgBr₂·2NH₃ composite was demonstrated as a solid-state Mg²⁺ electrolyte. The in situ decoration of MgBr₂·2NH₃ nanoparticles with an average size of 3.7 nm on the surface of Mg(BH₄)₂·1.9NH₃ improves the Mg²⁺ conductivity to 2.1 × 10^-4 S cm^-1 at 50 °C and offers long-term stability towards the Mg metal anode.
