Due to its huge capacity, Si is a promising anode material for practical applications in lithium-ion batteries. Here, using first-principles calculations, we study the applicability of the amorphous Si anode in multivalent-ion batteries, which are of great interest as candidates for post-lithium-ion batteries. Of the multivalent Mg2+, Ca2+, Zn2+, and Al3+ ions, only Mg2+ and Ca2+ are able to form Mg2.3Si and Ca2.5Si by alloying with Si, delivering very high capacities of 4390 and 4771 mA h g-1, respectively. Mg2.3Si has an 8% smaller
