• electrodes. MgH2 reacts with lithium ions in a reversible lithium-driven conversion reaction generating lithium hydride and magnesium metal: MgH2 + 2Li+ + 2e− Mg + 2LiH. Moreover, this conversion reaction is not restricted to MgH2. It can also be carried out with several different binary and ternary

• provide higher energy densities without compromising the safety of the battery. For example metals such as magnesium and aluminum were proposed [1][7]. Magnesium metal has been attracting an increased attention as it possesses higher volumetric capacities than lithium metal, i.e., 3832 mAh cm−3 vs 2061

• mAh cm−3 for lithium. It may also provide an opportunity for battery cost reductions due to its natural abundance in the earth crust (5th most abundant element) [7][8]. More importantly, despite the fact that magnesium metal is not competitive with lithium metal on both specific capacity (2205 mAh g−1
