What are rechargeable magnesium-ion batteries?

Rechargeable magnesium-ion batteries (MIBs) have attracted global attention owing to their distinct advantages (Fig. 1a) . Magnesium, the eighth most abundant element in the Earth's crust, is considered a nontoxic material, and it offers significant benefits for battery technology .

Is magnesium a viable cathode material for rechargeable batteries?

When applied to a complete cell configuration utilizing a magnesium anode, the material demonstrated a projected average operating voltage of around 3.2 V and an estimated energy density of approximately 800 mWh g −1, emphasizing its potential as a viable cathode material for rechargeable magnesium batteries.

Are magnesium ion batteries suitable for lithium-ion batteries?

The alloying mechanisms of elements combined with magnesium from groups 13, 14, 15, alkali metals, alkaline earth metals, and transition metals were detailed. Magnesium-ion batteries (MIBs) are promising candidates for lithium-ion batteries because of their abundance, non-toxicity, and favorable electrochemical properties.

What is a magnesium-sulfur battery?

For instance, in magnesium–sulfur (Mg S) batteries, magnesium acts as the anode and sulfur as the cathode, both of which are abundant in the earth and easily obtained from diverse mineral byproducts. The electrochemical reaction entails a two-electron transfer between magnesium and sulfur, resulting in a theoretical cell voltage of 1.77 V.
