AZ31 Magnesium Alloy Foils as Thin Anodes for Rechargeable Magnesium Batteries

International audienceIn recent decades, rechargeable Mg batteries (RMBs) technolo-gies have attracted much attention because the use of thin Mgfoil anodes may enable development of high-energy-densitybatteries. One of the most critical challenges for RMBs is findingsuitable electrolyte solutions that enable efficient and reversibleMg cells operation. Most RMB studies concentrate on thedevelopment of novel electrolyte systems, while only fewstudies have focused on the practical feasibility of using puremetallic Mg as the anode material. Pure Mg metal anodes havebeen demonstrated to be useful in studying the fundamentalsof nonaqueous Mg electrochemistry. However, pure Mg metalmay not be suitable for mass production of ultrathin foils(
