In recent decades, rechargeable Mg batteries (RMBs) technologies have attracted much attention because the use of thin foil anodes may enable development high-energy-density batteries. One most critical challenges for RMBs is finding suitable electrolyte solutions that efficient and reversible cells operation. Most RMB studies concentrate on novel systems, while only few focused practical feasibility using pure metallic as anode material. Pure metal been demonstrated to be useful in studying fundamentals nonaqueous electrochemistry. However, not mass production ultrathin foils (<100 microns) due its limited ductility. The metals industry overcomes this problem by ductile alloys. Herein, processing electrochemical was AZ31 alloys (3 % Al; 1 Zn). Thin-film presented dissolution deposition behavior complex ethereal electrolytes comparable foils. Moreover, it secondary battery prototypes comprising alloy (≈25 μm thick) Mgx Mo6 S8 Chevrel-phase cathodes exhibited cycling performance equal similar containing thicker anodes. possibility processable an important step realization
