Nonetheless, The progression of magnesium battery technology faces hindrances from the creation of a passivated film at the interface between the magnesium anode and electrolyte, along with the slow diffusion kinetics of Mg 2+.
In addition, good compatibility between electrolyte and cathode is essential to consider to achieve high-capacity magnesium batteries. The magnesium battery capacity depends on the utilization of the interfacial charge with the storage mechanism of the cathode.
The cathode consists of a compound that can reversibly embed/de-embed Mg 2+, and the anode consists of Mg metal or Mg alloy. The reaction mechanism of a rechargeable magnesium battery is as follows: In the discharge (Fig. 4 A), Mg 2+ are released from the anode, typically composed of Mg metal, and migrate through the electrolyte to the cathode.
Particularly, the natural abundance of Mg in the earth's crust reaches up to 2.3 %, making rechargeable magnesium batteries superior in terms of production cost (Fig. 1 C). Moreover, the deposited Mg is less likely to form dendrites on the anode, which makes the battery have higher safety , , .
However, the matching of magnesium salts and solvents is critical to the performance of magnesium batteries, and specific ratios of solvents may affect the matching with the high-voltage cathode. Therefore, electrolyte modification strategies should ensure interfacial compatibility with the electrodes.
A magnesium–air battery has a theoretical operating voltage of 3.1 V and energy density of 6.8 kWh/kg. General Electric produced a magnesium–air battery operating in neutral NaCl solution as early as the 1960s. The magnesium–air battery is a primary cell, but has the potential to be 'refuelable' by replacement of the anode and electrolyte.
