Highly reversible Mg-containing multicomponent high-entropy

Pure magnesium (Mg) and magnesium-based alloys were extensively investigated over decades [[17], [18], [19], [20]].Mg can store ∼7.6 wt% of hydrogen. Due to more negative enthalpy of hydride formation (MgH 2, Δ H = − 77 k J / m o l), a higher temperature and pressure are required to (de)absorb hydrogen.Therefore, it is challenging to use Mg alloys for
