Samples were mechanically milled under argon for 5 h; then characterised by X-ray diffraction (XRD), differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). Diffraction peaks of NaMgH3 phase shifted to higher angles and lattice parameters decreased due to the Li addition into the system. 2 and 3 endothermic reactions were observed for the Lix substituted samples (x = 0, 0.2, 0.5, 0.8). Li0.8Na0.2MgH3 hydride showed the best performance among the other quaternary hydrides (synthesised in this work) releasing 5.2 wt.% of H2 at 314 °C. Rehydrogenation of the decomposed LixNa1−xMgH3 (x = 0, 0.2, 0.5 & 0.8) samples was experimentally confirmed under 10 bar H2 at ∼250 °C.",
