Therefore, this progress report highlights a comprehensive and concise survey of the major progress in the history of secondary Mg–air batteries, and the detailed illustrations of corresponding reaction mechanisms.
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 , , .
