NREL-led team overcomes major technical obstacle in Mg-metal batteries by developing artificial solid-electrolyte interphase

Green Car Congress

Magnesium offers a number of advantages over lithium for rechargeable batteries: it is safer and earth-abundant, and doubles the total charge per ion, delivering larger theoretical volumetric capacity compared with a typical lithium-ion battery. Further, in Mg batteries (MB) the anode is energy-dense Mg metal (~?3,830
