UMD, Army Researchers design new electrolyte enabling high energy density rechargeable Mg and Ca batteries

Green Car Congress

Rechargeable magnesium and calcium metal batteries (RMBs and RCBs) are promising alternatives to lithium-ion batteries because of the high crustal abundance and capacity of magnesium and calcium. A paper on their work is published in the journal Science. Yet, they are plagued by sluggish kinetics and parasitic reactions. Singyuk Hou et al.

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 —Son et al.
