KIST team develops activation strategy for magnesium metal enabling efficient operation of Mg batteries

Green Car Congress

Despite these advantages, the difficulty of efficiently charging and discharging magnesium metal due to its reactivity with electrolytes has hindered its commercialization. The highest energy density can be obtained by directly utilizing magnesium metal as a anode, of which volumetric capacity is about 1.9 times higher than lithium metal.
