水系镁空气电池电解液研究进展OA

Mg-air batteries have garnered significant attention in recent years due to their outstanding advantages,including high theoretical energy density,excellent safety,low cost,and environmental friendliness.However,systematic reviews concerning aqueous Mg-air battery electrolytes remain relatively scarce.The Mg anode is prone to self-corrosion,discharge product accumulation,and severe block effect in aqueous environments.This results in low anode utilisation,suboptimal operating voltages,and pronounced voltage fluctuations,making the electrolyte a critical factor constraining the practical application of Mg-air batteries.To address this,this paper systematically reviews the fundamental properties and key influencing factors of aqueous Mg-air electrolytes,focusing on electrolyte system selection,interfacial control strategies,and additive mechanisms.The review covers the structural characteristics and applicability of chlorinated and chlorine-free near-neutral electrolytes,the regulatory roles of inorganic,organic,and composite additives,and the synergistic effects of anions at the electrolyte/anode interface.Finally,future development directions for aqueous Mg-air electrolytes are proposed,including in-depth understanding of interfacial regulation mechanisms,green design of electrolyte systems,and rapid formulation screening based on machine learning.This paper aims to provide reference for the research and application of high-performance Mg-air battery electrolytes.
