Mg-Air Battery with High Coulombic Efficiency and Discharge Current by Electrode and Electrolyte Modification

Addressing corrosion issues in Mg-air batteries is vital for improving energy storage technologies. Unlike traditional methods that focus solely on electrode materials or electrolyte composition, this study introduces a novel integrated strategy that combines electrode surface modification and controlled electrolyte content. Through comprehensive numerical simulations, the details of corrosion kinetics and ion migration mechanisms at the atomic level are revealed. Our findings demonstrate exceptional Coulombic efficiencies (>97%) and enhanced ion diffusion by over three times, ensuring the desired discharge current. This approach not only overcomes traditional limitations but also offers important insights for the research community, paving the way for the design of high-performance Mg-air batteries in next-generation energy storage systems.
